Reels vs TikTok vs Shorts [2026]: 1080×1920, 3-Min Cap

Export one 9:16 file at 1080 x 1920 pixels, keep it at 3 minutes or less, and it clears all three platforms. Instagram Reels size, TikTok video size and YouTube Shorts length differ far more in time limits than in pixels. Shorts stop at 3 minutes, Reels run to 20 minutes in the app, and TikTok allows 10 minutes recorded or 60 minutes uploaded. Bloomberg reported on October 26, 2026 that Instagram is ramping up its video strategy against TikTok and YouTube, so the Reels numbers below are worth rechecking every few months.

The catch sits in distribution, not in the upload screen. Instagram accepts a Reel of up to 20 minutes but does not recommend Reels longer than 3 minutes to people who do not follow you. YouTube classifies a square or vertical upload as a Short only when it runs 3 minutes or less. That makes 180 seconds the practical ceiling for a single file you want to post everywhere.

This comparison belongs to our platform video specs section. It covers the dimensions, length caps, frame rates and file advice for each platform, then turns them into a render preset, a crop guide and a migration plan. Specs here come from platform documentation as relayed in spec guides dated October 13 to October 30, 2026, and were last checked on November 2, 2026. Where sources disagree, the tables use the more conservative figure.

The Five Numbers That Cover Most Questions

• 9:16 is the standard vertical ratio on all three platforms.
• 1080 x 1920 is the common export size for Reels, TikTok and Shorts.
• 3 minutes (180 seconds) is the Shorts ceiling and the Reels reach threshold for non-followers.
• 20 minutes is the Reels maximum in the app.
• 10 and 60 minutes are TikTok’s in-app recording and device-upload limits.

If you remember only those five, you can plan almost any short-form export. The rest of this article explains where each number comes from, which ones are soft, and how to build a workflow that does not break when a platform changes a limit. Most of the changes in the past two years have moved length caps, not pixel counts, so the dimension advice has stayed stable while the duration advice keeps shifting.

One practical note before the detail. None of the three platforms publishes a single mandatory pixel size for organic posts in the sources checked. They publish a recommended size, a minimum or an accepted range. That is why you will see the words recommended, accepted and common throughout. Treat 1080 x 1920 as the safe default and not as a legal requirement.

The order of the sections follows how a creator works. Each platform gets its own spec table first, then one combined table, then the benchmarks and costs. After that come the practical parts: a render preset, the crop arithmetic for wide footage, six worked scenarios, a migration plan and a verdict. If you only need a number, jump to the combined table. If you are rebuilding a template library, read the migration guide.

Instagram Reels Size: 1080 x 1920, 9:16 and a 20-Minute Ceiling

Instagram Reels size starts with the full-screen vertical frame. The recommended export is 1080 x 1920 pixels at 9:16, and the minimum resolution reported in 2026 spec guides is 720 pixels. Instagram accepts ratios from 1.91:1 (wide) to 9:16 (tall), which means a 16:9 clip technically uploads without a crop. It will sit in the middle of the frame with empty bands above and below, so most creators reframe instead.

Frame rate is the one spec where Instagram sets a floor. The reported minimum is 30 frames per second, so a 24 fps cinematic export sits below it. If your footage is 24 fps, conform it to 30 in your editor before export instead of letting the app resample it. TikTok and YouTube did not state a frame-rate floor in the sources checked.

Length is where Reels changed most. The Instagram Help Center lists 20 minutes for a Reel recorded in the app. Guides that still say 90 seconds are out of date and should not be treated as current. Some upload and scheduling routes cap lower, with Buffer reporting a 15-minute limit and a publishing-API range of 3 seconds to 15 minutes reported in one 2026 summary. One spec roundup still lists 3 minutes as the Reels maximum, which conflicts with the Help Center figure. The table above uses 20 minutes for in-app Reels and treats 3 minutes as a reach rule, because that reading matches the most sources.

The reach rule matters more than the cap. Instagram does not recommend Reels longer than 3 minutes to people who do not follow the account. A 12-minute Reel will publish and your followers will see it, but it loses the discovery surface that makes Reels worth posting. If growth is the goal, treat 180 seconds as the working ceiling.

For editing, the practical effect is simple. Set your timeline to 1080 x 1920, check that the frame rate is 30 or higher, and cut the discovery version to 3 minutes or less. If you also want a longer cut for followers, export it as a second file instead of stretching the first. Two files take ten extra minutes and protect the reach of the short one.

What Instagram is testing next

Several October 2026 reports describe Instagram widening beyond vertical clips. According to those reports, a format called Features began testing on October 26 with selected US creators after earlier tests in Brazil, allowing horizontal videos of up to 90 minutes. A test linking up to eight short Reels clips to one longer Feature was also reported, along with a Series format that groups Reels into episodic collections. Instagram’s TV app was reported on Apple TV and Amazon Fire TV, with Samsung TVs and Google TV added. The Los Angeles Times reported on October 26 that Instagram chief Adam Mosseri and Tessa Lyons, vice president of product, are overseeing the video push.

Treat all of that as testing, not as a settled spec. The reports describe limited rollouts, and the sources do not show that Features has reached every account or market. Features does not replace Reels, so the Reels numbers in this article stay valid. Revisit your export plan only when Features reaches your account and shows a published limit.

TikTok Video Size: 9:16, 1080 x 1920, 10 Minutes In-App and 60 Uploaded

TikTok video size follows the same vertical logic. The recommended format is 9:16, and 1080 x 1920 pixels is the common export. One spec guide in the research set calls the claim that 1080 x 1920 is the only correct size too absolute, and that fits what the platform documents. TikTok’s advertising specification, updated in late October 2026, sets a minimum of 540 x 960 pixels for 9:16 ad video and also accepts 16:9 and 1:1 for the ad products cited. Organic posts do not have a published pixel rule in the material checked.

The same advertising documentation reportedly lists other supported dimensions, including 720 x 1280. Only one source showed that list, so use it as a hint and confirm it in TikTok’s own ad manager before building an ad template around it. The 5 to 60 second range applies to TopView and other specified ad types, so do not read it as an organic limit.

Length is the real difference from the other two. A clip recorded inside TikTok can run 10 minutes, and a file uploaded from your device can run 60 minutes. Summaries that say TikTok caps at 10 minutes are incomplete because they skip the upload route. For creators who edit in a desktop app, the 60-minute figure is the one that applies, since you export a file and upload it.

What the sources do not confirm is equally useful to know. They did not provide verified current limits for organic file size, bitrate, codec, frame rate or safe-zone dimensions. If a template or an editor preset claims exact TikTok bitrate numbers, check the upload screen and the help centre before trusting it. A clean H.264 MP4 with AAC audio at 1080 x 1920 is the safe path, and that recommendation matches what a cross-platform specs guide gives for all three platforms.

The 60-minute upload limit changes how you should think about TikTok video size and length together. A tutorial that runs 8 minutes in 1080 x 1920 is a normal TikTok upload, while the same file is too long to be a Short and sits past the Reels reach threshold. If your audience lives on TikTok, you do not need to chop every video into 60-second pieces. Cut for the story, not for an old limit.

YouTube Shorts Length and Dimensions: 3 Minutes, Square or Vertical, 1080p Cap

YouTube Shorts length is the clearest number in this comparison. YouTube’s Help documentation says a Short can run up to 3 minutes, and a video uploaded on or after October 15, 2024 that is square or vertical and 3 minutes or shorter is categorized as a Short. The documentation was updated on October 27, 2026 and still carries the same limit, so nothing in the latest check points to a change.

You will still find forum posts that say Shorts must stay under 60 seconds. Those conflict with YouTube’s own pages, so ignore them. The current rule took effect on October 15, 2024, which means any guide older than that date is describing a different rule.

Dimensions are looser than people expect. YouTube confirms a maximum upload resolution of 1080p but does not set one mandatory pixel size for Shorts. A square 1080 x 1080 file qualifies as a Short in the same way a 1080 x 1920 file does. A 16:9 file does not qualify, and YouTube recommends a wider format such as 16:9 when you want a video treated as long-form. That makes the aspect ratio the real gate: anything wider than square falls into the standard video feed no matter how short it is.

The 1080p ceiling has one editing consequence. Uploading a 4K vertical master gains nothing on Shorts, because the platform stops at 1080p, and it only adds upload time. Render at 1080 x 1920 and keep the 4K original in your archive for a future re-cut. That also keeps one preset for all three apps.

Side-by-Side Specs Table: Reels vs TikTok vs Shorts

Read the table by row, not by column. The pixel rows are almost identical across all three, and the length rows are where the platforms split. If you build a template once at 1080 x 1920 and 30 fps, the only per-platform decision left is how long to cut the clip and whether to trim the caption area for each app’s interface.

Rows marked not confirmed mean the sources checked did not state a verified figure. They do not mean the platform has no limit. File size caps, bitrate ceilings and safe-zone pixel margins exist in practice, and you will see them on the upload screen or in the help centre. This article does not guess at them because a wrong number sends you to re-export a finished clip.

Benchmarks: What the Length and Reach Data Shows

Benchmarks for platform specs are thin, and it is better to say so than to invent a chart. The one dated performance figure in the research is the study of almost 10 million Reels cited in the 30 Second Productions guide, which found that 45 to 60 seconds earned the most views and engagement. That is a Reels result. It says nothing about Shorts or TikTok, and the sources did not provide an equivalent retention figure for either.

Meta also clarified on October 22, 2026 that a Reel’s public view count can include repeated views by the same person and paid views from boosted Reels, so views do not necessarily equal unique viewers. That is worth remembering before you judge longer formats by their view counts. It does not tell you that longer Reels perform better. Video matters, and short clips still get the strongest measured response on Reels.

On reach, Meta’s Portuguese-language newsroom post of October 22, 2026 argues that engagement and not follower count drives how far a post travels. It names watch time, likes and comments among the signals, and says content that gets many views, shares and reactions in a short window is more likely to be shown to others. Meta also clarified the same week that a Reel’s public view count can include repeated views by the same person and paid views from boosted Reels, so views do not equal unique viewers. Keep that in mind when you compare Reels numbers with TikTok or Shorts analytics, since each platform counts a view in its own way.

Reportedly, Meta also posted 3.64 billion daily active people across its apps for the third quarter of 2026. That figure covers the whole Meta family, so do not read it as a Reels audience. The takeaway for this comparison is simple: the pixel specs tell you whether your video uploads, and the length and engagement data tell you whether anyone sees it.

Three gaps deserve a plain mention. The sources gave no retention curve for Shorts, no completion-rate figure for TikTok and no frame-rate benchmark for any platform. If your channel analytics show a drop at second 20 on every clip, that tells you more than any industry average. Use the benchmarks above to set your starting length, then let your own numbers move it.

Cost: What Each Platform Charges to Post

Posting is free on all three. The research found no official price for publishing a Reel, a TikTok or a Short, and no paid consumer plan tied to standard posting. Where money enters is promotion. Boosted Reels add paid views to a Reel’s public view count, as Meta noted in October 2026, and TikTok’s TopView ads follow the ad specs described above.

No official price for posting Reels, TikTok videos or organic YouTube Shorts was identified, so this article leaves subscription plans out of the table. The real cost of short-form video is production time, plus any editing software you pay for. Check the export limits of your editor before you commit, because a free tier that stamps a watermark or caps resolution below 1080 x 1920 defeats the whole preset.

There is also a quieter cost in storage and upload time. A 3-minute vertical clip is small, but a 60-minute TikTok upload is not, and a failed upload at minute 40 wastes the evening. Compress sensibly, test on a short clip first and keep an original master so you never re-encode a re-encode.

Render Settings for One Master File

That table is the whole preset. Build it once in your editor, name it Vertical Master, and reuse it. The master satisfies the Shorts ceiling, the Reels reach threshold and the TikTok limits at once, which is why a 3-minute vertical MP4 became the default in the October 2026 specs guides. H.265 may shrink files further, but the sources recommend H.264 for cross-platform posting, so start there and move only if a platform asks for something else.

Here is an example command if you export from the command line with ffmpeg. The quality value is my starting point, not a platform requirement, so adjust it to the clip.

ffmpeg -i input.mov -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2" -r 30 -c:v libx264 -crf 18 -pix_fmt yuv420p -c:a aac -b:a 192k -movflags +faststart -t 180 vertical-master.mp4

The scale and pad filter fits the clip inside a 1080 x 1920 canvas without stretching it, the -r flag sets 30 fps, and -t 180 stops the export at 180 seconds. The sources did not confirm a file size cap for any platform, so check the upload screen if a long export fails. For planning, the arithmetic is simple: file size in megabytes equals bitrate in megabits per second times seconds, divided by 8. At an example 8 Mbps, a 180-second clip is about 180 MB and a 20-minute clip is about 1,200 MB. Those are illustrations, not platform limits.

Frame rate, codec and audio

Frame rate comes first because Reels states a floor. A 30 fps timeline satisfies it, and a 60 fps timeline also does, though the sources give no benefit or penalty for 60. If your camera shoots 24 fps, either shoot 30 or conform in the editor. Mixed frame rates on one timeline cause stutter, so convert clips before you cut.

For codec and container, the cross-platform advice in the October 2026 guides is MP4 with H.264 video and AAC audio. It plays on nearly every phone and every upload pipeline, which is the reason it works as a neutral choice. For audio, export stereo AAC and keep dialogue clear and centered, because phone speakers flatten everything else.

If you also want a branded opener on the master, Vipid lists intro themes with their resolution, length and frame rate, which lets you match a theme against your 9:16 preset before you pick one. Keep any opener short on short-form clips, since the first seconds decide whether a viewer stays.

Converting 16:9 to Vertical: The Crop Math

This is straight arithmetic, so it holds on every platform. A 16:9 clip placed inside a vertical frame fills only a small part of the height. The rest is empty, which is why landscape uploads to Reels look small. A center crop does the opposite and throws away most of the picture, so a talking head survives the crop and a wide gameplay shot does not.

Three approaches work in practice. First, reframe each shot by hand with keyframed position so the subject stays inside the 9:16 window. Second, stack the clip: place the 16:9 footage in the middle and use the empty bands for captions, a facecam or a blurred copy of the same clip. Third, record vertical from the start. The third option costs nothing and gives the cleanest result, and it avoids the Shorts rule that a 16:9 upload is not a Short at all.

Keep captions and faces away from the screen edges. Each app places its own buttons and text over the frame, and the sources checked did not give pixel margins for safe zones, so use a generous inner margin and test on a phone before you post. A caption that sits too close to the bottom edge is the most common casualty. Burned-in captions also need to match your 1080 x 1920 canvas, so build the caption style inside the same project instead of adding it after export.

Real-World Examples: Six Common Clips and Where They Fit

The six cases below are worked scenarios built from the specs above. They are planning examples, not reports of what any named creator did.

Example 1: a 45-second tip clip. Shot vertical on a phone and exported at 1080 x 1920, this clip sits inside every limit. It also lands in the 45 to 60 second band that drew the most views in the almost 10 million Reels study. Post the identical file to all three platforms and change only the caption text.

Example 2: a 2-minute tutorial. At 120 seconds this fits the Shorts and Reels reach thresholds with 60 seconds to spare. The risk is detail: a screen recording at 1920 x 1080 shrinks to 608 pixels tall in a vertical frame, so text becomes unreadable. Crop to the active window, zoom in and add large captions instead of posting the full desktop.

Example 3: an 8-minute vlog cut. This is too long for Shorts and past the Reels reach threshold, so it fits TikTok best, since a 480-second file is well under the 60-minute upload limit. On Instagram it publishes but stays mostly in front of followers. Cut a 60 to 90 second highlight for discovery and mention the full version in the caption.

Example 4: a 16:9 gameplay highlight. A landscape clip is not a Short, and in Reels it shows with large empty bands. Stack it with a facecam in the lower half or reframe to follow the action. If the full match matters, upload the 16:9 file as a normal YouTube video and cut a vertical version separately. That gives you one long-form upload and one discovery clip from the same session.

Example 5: a square product demo. A 1080 x 1080 file qualifies as a Short because YouTube accepts square, sits inside the Reels range, and is accepted in TikTok’s ad products. It fills only part of a vertical frame, so a true 9:16 version uses the screen better in organic feeds. Square works better for a single product on a plain background than for a person talking.

Example 6: a TikTok ad creative. The ad specification asks for 9:16 at 540 x 960 or higher, and TopView runs 5 to 60 seconds. Build the ad at 1080 x 1920 so the creative also works as an organic post, then trim to the ad length. Always confirm the dimensions in the ad manager, since the platform updates its ad documentation more often than organic specs.

Which Platform for Which Job: Use-Case Recommendations

• Short, punchy discovery clips (under 60 seconds): post to all three from one master. Reels data favors the 45 to 60 second range.
• Tutorials and explainers of 1 to 3 minutes: use Shorts and Reels for discovery and keep the 3-minute ceiling. TikTok is also fine at this length.
• Long-form stories of 4 to 10 minutes: choose TikTok or a regular YouTube upload. A Reel at this length will publish but lose non-follower reach.
• Lectures and full episodes up to an hour: use YouTube long-form, since TikTok allows uploads up to 60 minutes but the format is not built for it.
• Paid campaigns: build to the TikTok ad spec of 9:16 at 540 x 960 or higher and the Meta ad specs, then export at 1080 x 1920.
• Brand intros and logo stings: keep them to the first few seconds and render them at 1080 x 1920 so they match the body of the clip.

The pattern is that length sorts the platforms. Under 3 minutes, any of them works. Past 3 minutes, TikTok and long-form YouTube pull ahead, and Instagram’s own tests of Features suggest Meta wants to cover that range too. If you only have time for one extra step, make the discovery cut first and the long version second.

Solo creators should favor the simplest workflow: one vertical master, one caption, three uploads. Small studios can split the work, with one editor owning the master and another owning platform-specific captions and thumbnails. Streamers who clip highlights can set the 180-second limit as a hotkey-length rule so every clip fits every platform by default.

From the Vipid archive: the animated logo intro theme is one place to start for a short branded opener.

Migration Guide: Moving from Old Limits to the 2026 Workflow

Many creators still work from templates built around 60-second Shorts and 90-second Reels. Those limits no longer apply, and old templates quietly cap your clips. Follow these steps to update a library.

1. List every preset and template that mentions 60 seconds or 90 seconds and mark it for review.
2. Create one project preset at 1080 x 1920, 9:16 and 30 fps. Name it clearly.
3. Set the sequence length to 180 seconds so the Shorts ceiling and the Reels reach threshold are built in.
4. Save an export preset as MP4 with H.264 video and AAC audio.
5. Re-render your three best-performing older clips from the original footage, not from the compressed file, so quality does not drop twice.
6. Replace any 16:9 intros and lower thirds with vertical versions built at 1080 x 1920.
7. Test one clip on each platform and compare the upload screens. Write down any size, length or rotation warning.
8. Review the specs once a quarter, since the October 2026 Instagram tests show limits can shift.

Step five matters most for older libraries. Re-encoding an already compressed file stacks compression artifacts, and the loss shows on gradients and small text. Keep your project files and exports organized by date so the original is always available. If your old library used 4K horizontal masters, you can still reuse the footage, but plan to reframe it at 1080 x 1920 rather than scale the whole frame.

Two mistakes come up again and again. The first is trusting a spec table with no date. Limits moved in 2024 and 2025, and any guide that does not say when it was checked may describe an older rule. The second is treating a recommendation as a requirement. Instagram’s 3-minute figure is a reach rule, YouTube’s 3-minute figure is a classification rule, and neither is a hard stop for uploading. Knowing which kind of limit you face tells you what actually breaks when you go over.

Pros and Cons of Each Platform for Video Specs

Reels gives the most room and the least certainty. The 20-minute ceiling is generous, but the reach rule and the route-specific caps mean you need to read the fine print each time. TikTok gives the most room for long uploads, yet its organic technical specs are the least documented of the three in the sources checked. Shorts is the strictest and the clearest, because YouTube states its rule in one sentence and has kept it since October 2024.

For a creator who values predictability, the clarity of the Shorts rule is a real advantage. You know that a square or vertical clip of 3 minutes or less is a Short, and you can plan around it. For a creator who values flexibility, TikTok’s 60-minute upload limit and Instagram’s 20-minute ceiling leave more space to experiment.

Verdict: Build for 1080 x 1920 and 180 Seconds

The data points to a single recommendation. Export a 9:16 MP4 at 1080 x 1920, 30 fps or higher, with H.264 video and AAC audio, and keep it at 180 seconds or less. That one file satisfies the Instagram Reels size guidance, the TikTok video size recommendation and the YouTube Shorts length rule. It also keeps the clip eligible for Instagram’s non-follower recommendations and for the Shorts shelf.

Pick the platform by length, not by pixels. Use Shorts when you want the clearest documented rule, Reels when you want discovery inside Instagram and a clip near a minute, and TikTok when the clip runs past 3 minutes or you need the 60-minute upload route. For ads, check the platform’s current ad specification before you render, since ad documents change more often than organic limits.

Two caveats keep this verdict honest. First, several rows in the specs table read not confirmed, so file size caps, bitrate limits and safe-zone margins still need a check on the upload screen. Second, Instagram’s Features, Series and TV tests could change the Reels picture within months. Nothing in the October 2026 material shows a change to the 1080 x 1920 default, so the master file advice should hold even if the length caps move.

Common questions

What is the best Instagram Reels size in 2026?

Use 1080 x 1920 pixels at 9:16. Instagram accepts ratios from 1.91:1 to 9:16 with a minimum of 720 pixels and 30 frames per second, but the full-screen vertical export avoids bands and cropping.

How long can a YouTube Short be?

Up to 3 minutes. YouTube Help, updated October 27, 2026, says square or vertical videos of 3 minutes or less uploaded on or after October 15, 2024 are categorized as Shorts.

What is the TikTok video size and length limit?

The recommended format is 9:16, commonly 1080 x 1920 pixels. Videos recorded in the app can run 10 minutes, and videos uploaded from a device can run 60 minutes.

Can I post the same video to Reels, TikTok and Shorts?

Yes, if it is vertical, 1080 x 1920 and 180 seconds or less. That meets the Shorts ceiling and the Reels reach threshold, and it sits well inside TikTok’s limits.

Is a 16:9 video allowed as a Reel or a Short?

A 16:9 clip falls inside Instagram’s accepted range, so it uploads as a Reel with empty bands. YouTube does not treat 16:9 as a Short and recommends it for long-form video.

Why does my long Reel get less reach?

Instagram does not recommend Reels longer than 3 minutes to people who do not follow the account. The Reel still publishes and followers can see it, but discovery drops.

Do Reels, TikTok and Shorts charge to post?

No official price for posting was identified for any of the three. Costs arise from ads, boosted posts and your own editing software.
