YouTube Shorts Size & Dimensions in 2026 (Plus Reels & TikTok)
The YouTube Shorts size is 1080×1920 pixels — a 9:16 vertical frame — with a maximum length of 3 minutes and a maximum resolution of 1080p. Anything square or taller than square, up to 3 minutes, is automatically treated as a Short; anything wider (like 16:9) never is, no matter how short.
Reels and TikTok use the same 1080×1920 canvas, so one properly sized vertical video works across all three platforms. The details below — length ceilings, what happens to wrong-sized uploads, safe zones — were verified against each platform's official documentation on July 12, 2026, because these specs change more often than most articles admit.
Quick reference: all three platforms
| Spec | YouTube Shorts | Instagram Reels | TikTok |
|---|---|---|---|
| Aspect ratio | 9:16 (square to vertical qualifies) | 9:16 recommended (accepts 1.91:1 to 9:16) | 9:16 (also accepts 1:1, 16:9) |
| Resolution | 1080×1920 — capped at 1080p | 1080×1920 standard (max 1920 horizontal px per Meta's spec) | 1080×1920 standard (up to 4K per TikTok's developer spec, played back at ~1080p) |
| Max length | 3 minutes | 20 minutes — but see the 3-minute catch below | 60 min uploaded / 10 min recorded in-app |
| File | No Shorts-specific cap (general 256 GB / 12 h) | No cap published for app uploads (API: 300 MB) | 4 GB (per TikTok's developer spec) |
| Formats | MP4, MOV, WebM, AVI + most others | MOV/MP4, H.264 or HEVC (per Meta's API spec) | MP4 recommended, also WebM/MOV |
YouTube Shorts dimensions, explained
What makes a video a Short is math, not metadata. YouTube's rule: any video up to 3 minutes with a square or vertical aspect ratio is automatically categorized as a Short. No #Shorts hashtag needed — and no way to opt out except using a wider ratio. The 3-minute ceiling has applied to uploads since October 15, 2024 (Official Artist Channels only got it on December 8, 2025); before that it was 60 seconds.
Three details most creators miss:
- Shorts are capped at 1080p. Upload a 4K vertical master and YouTube downscales it. Rendering your Shorts export above 1080×1920 buys nothing.
- 16:9 videos can't be Shorts. A 30-second landscape clip stays a regular video on the watch page. If you want it in the Shorts feed, it needs to become vertical first — that's the job of a YouTube to Shorts converter.
- The Content ID trap: a Short longer than 1 minute with any active Content ID claim — even a manual one — gets blocked worldwide. If you clip content with licensed music, staying under 60 seconds is the safer play.
What if your video is the wrong size?
YouTube pads non-9:16 videos with background color and TikTok letterboxes 16:9 uploads with black bars — neither crops your frame. Instagram is the exception: Meta's own wording is that non-9:16 reels get "cropping or blank space," and on phone screens taller than 9:16 it may zoom in and crop the edges. Either way your video looks small or loses its edges — and in a full-screen vertical feed, both lose.
That's the actual reason the "shorts size" question matters: the fix isn't the export settings, it's reframing. Cropping 16:9 down to 9:16 cuts two-thirds of the frame, so a static center-crop routinely beheads speakers or loses the action. That's the problem EzClip's free reframe tool exists for — it tracks the subject and keeps them centered while converting to 9:16, free for clips up to 2 minutes — one short a day on a free account, no card.
Instagram Reels size and the 3-minute catch
Reels use the same 1080×1920 standard. Meta's developer specification caps the picture at 1920 horizontal pixels and accepts 23–60 fps (re-verified September 17, 2026) — and the 9:16 recommendation is explicit: anything else gets cropped or padded.
The big 2025 change: Reels can now be up to 20 minutes long. The catch, straight from Instagram's help center: "Reels over 3 minutes won't be recommended to new audiences." So the practical ceiling for growth content is still 3 minutes — the 20-minute allowance is for your existing followers, not for reach.
Two gotchas worth knowing: cover images that aren't 9:16 get center-cropped for the Reels tab and cropped again to a square for the Feed grid, so keep cover subjects dead-center. And if you publish through a scheduling tool, the API is stricter than the app: 15 minutes and 300 MB max.
Reels also carry an encoding specification — container, codec, frame rate and chroma — that decides whether an upload is accepted at all, separately from its size. Our Instagram Reels size and dimensions guide has the full Meta spec.
TikTok size and the record-vs-upload split
TikTok's spec is the most permissive on paper: 1080×1920 at 9:16 is the working standard (TikTok's own docs only publish minimums — its developer spec accepts up to 4K, though playback tops out around 1080p; turn on Settings → Account → Data Usage → High quality upload to hold 1080p delivery). Videos recorded in the app cap at 10 minutes; uploaded files can run to 60 minutes. Max file size is 4 GB per TikTok's developer documentation.
One sneaky behavior: if you pick a sound before posting, the sound's length can cap your video's length. And TikTok's UI eats more of the frame than the other platforms — its own safe-zone template for a 1080×1920 canvas keeps roughly the bottom 484px (caption, sound ticker), right 140px (like/share rail), and top 130px clear. Those numbers come from TikTok's downloadable ad template rather than a published spec, but they're a reasonable proxy for what the organic UI covers. Keep faces and captions in the middle of the frame and you're safe on all three platforms.
One vertical video size for every platform
The specs converge on a simple rule: make one 1080×1920 master, 3 minutes or less, subject centered. That one vertical video size qualifies as a Short, stays recommendable on Reels, and posts cleanly to TikTok — one file, three feeds, zero re-exports.
Getting a platform-ready vertical cut from long-form footage is the part worth automating. An AI clip generator does the whole chain in one pass — finds the strongest moments in a long video, reframes each to subject-tracked 9:16 at platform-optimized resolution, and writes titles and hashtags — with one free trial clip to test on your own channel, no card needed.
FAQ
What size is a YouTube Short in pixels?
1080×1920 pixels — those dimensions are 9:16 vertical at 1080p, which is also the maximum resolution YouTube allows for Shorts. Higher-resolution uploads get downscaled.
Can YouTube Shorts be 3 minutes long now?
Yes. Since October 15, 2024, any square-or-vertical video up to 3 minutes is automatically classified as a Short. Before that date the limit was 60 seconds.
Is YouTube Shorts 16:9 or 9:16?
9:16 (vertical). A 16:9 video is never treated as a Short regardless of length — it stays a regular video. Square (1:1) and anything between square and vertical does qualify.
Are Reels and Shorts the same size?
Yes — both use a 1080×1920, 9:16 canvas, so the same file works for both. The difference is length rules: Shorts cap at 3 minutes, while Reels allow up to 20 but stop recommending anything over 3 minutes to new audiences.
What happens if I upload a horizontal video as a Short?
YouTube won't crop it — but it also won't make it a Short. Wider-than-square videos are always long-form. To get landscape footage into the Shorts feed, convert it to 9:16 first (a subject-tracking reframe tool avoids the beheaded-speaker problem of static crops).
Specs verified July 12, 2026 against YouTube Help, Instagram Help Center, Meta developer docs, and TikTok's help and developer documentation. Platforms change these numbers — if something above looks stale, it probably changed again; we re-verify quarterly.
