Social media video and image sizes
The dimensions, ratios, length limits and file caps for every placement worth posting to, in one table you can search.
| Placement | Size | Ratio | Max length | Max file | Copy |
|---|---|---|---|---|---|
| YouTube — Video, 1080p The default upload. Anything narrower is pillarboxed. | 1920×1080 | 16:9 | 12 hours | 256 GB | |
| YouTube — Video, 1440p Worth it on detailed footage — YouTube gives 1440p a better codec than 1080p. | 2560×1440 | 16:9 | — | — | |
| YouTube — Video, 4K Also the safest source for a 1080p final, since the downscale hides compression. | 3840×2160 | 16:9 | — | — | |
| YouTube — Shorts Vertical and under the cap is a Short; over it, the same file is an ordinary video. | 1080×1920 | 9:16 | 3 minutes | — | |
| YouTube — Thumbnail Upload smaller than 1280 wide and no maxresdefault is ever generated. | 1280×720 | 16:9 | — | 2 MB | |
| YouTube — Channel banner Only the middle 1546×423 is visible on every device. Keep text inside it. | 2560×1440 | 16:9 | — | 6 MB | |
| YouTube — Channel avatar Displayed as a circle, so corners are lost. | 800×800 | 1:1 | — | 4 MB | |

| TikTok — Photo post Carousels use the same frame as video, and the same safe area. | 1080×1920 | 9:16 | — | — | |
| TikTok — Profile photo Shown small and circular. Upload larger and let it downscale. | 200×200 | 1:1 | — | — | |
| Instagram — Reel The grid crops the preview to 4:5 — keep the hook inside that. | 1080×1920 | 9:16 | 3 minutes | 4 GB | |
| Instagram — Feed post, portrait The tallest the feed allows, and the most screen a post can take. | 1080×1350 | 4:5 | — | — | |
| Instagram — Feed post, square | 1080×1080 | 1:1 | — | — | |
| Instagram — Feed post, landscape | 1080×566 | 1.91:1 | — | — | |

| Instagram — Profile photo | 320×320 | 1:1 | — | — | |
| Facebook — Feed video 4:5 outperforms 16:9 in the feed for the same reason it does on Instagram. | 1080×1350 | 4:5 | 240 minutes | 10 GB | |
| Facebook — Reel | 1080×1920 | 9:16 | 90 seconds | — | |
| Facebook — Cover photo Cropped differently on mobile and desktop — keep the subject centred. | 1640×856 | 1.91:1 | — | — | |
| X — Video, landscape Longer and larger uploads are a paid feature. | 1280×720 | 16:9 | 2 min 20 s | 512 MB | |
| X — Video, vertical | 720×1280 | 9:16 | — | — | |
| X — Header image | 1500×500 | 3:1 | — | — | |
| LinkedIn — Feed video | 1920×1080 | 16:9 | 15 minutes | 5 GB | |
| LinkedIn — Feed video, vertical LinkedIn's own feed favours vertical now, which it did not two years ago. | 1080×1920 | 9:16 | — | — | |
| LinkedIn — Page cover | 1128×191 | 5.9:1 | — | — | |
| Twitch — Stream 6000 kbps is the practical video ceiling. Above it, viewers buffer. | 1920×1080 | 16:9 | — | — | |

| Twitch — Profile banner | 1200×480 | 5:2 | — | 10 MB | |

| Pinterest — Video pin | 1080×1920 | 9:16 | 15 minutes | 2 GB |
33 of 33 placements. Dimensions are the recommended upload size, not a requirement — every platform here accepts a smaller file at the same ratio and scales it. Length and file caps are the part that changes, so confirm them before a launch you cannot re-render.
What this does
A reference table of the sizes each platform actually wants: the pixel dimensions, the aspect ratio, the maximum length and the file size cap for YouTube video and thumbnails, Shorts, TikTok, Instagram feed, Reels and Stories, Facebook, X, LinkedIn and Twitch's overlays and panels. Search it, filter it by platform, and copy any size as a width and height ready to paste into an editor. Two things worth knowing before you use it: platforms change these, and the ones that matter are the ratio and the safe area rather than the exact pixel count. A 1080×1920 file and a 720×1280 file are both 9:16 and both accepted, and the second one just looks worse.
How to use the size guide
- 01
Find your placement
Filter by platform or search for the placement by name: Reel, Short, thumbnail, panel, banner.
- 02
Take the dimensions
Copy the width and height straight into your editor's sequence settings or your canvas size.
- 03
Check the limits too
The row carries the length cap and the file size cap alongside the dimensions, which are the two things that get an upload rejected after you have already rendered it.
Questions
What size should a YouTube thumbnail be?
1280×720, 16:9, under 2MB, as a JPG, PNG, GIF or WebP. That is YouTube's stated requirement and it is also the size YouTube stores as maxresdefault, so a thumbnail uploaded smaller than 1280 wide never gets a full-size version generated for it.
What size is an Instagram Reel?
1080×1920, 9:16. The feed crops the preview to 4:5, so keep anything that has to be legible from the grid within the middle of the frame, and keep text clear of the bottom fifth where the caption and buttons sit.
How long can a YouTube Short be?
Up to three minutes. Anything vertical and under that length is treated as a Short; go over it and the same file is published as an ordinary video instead.
Do these sizes change?
Yes, and the length limits change most often. The ratios are the stable part. 16:9, 9:16, 4:5 and 1:1 have been the shapes for years and are what to design against. Check a platform's own help page before a launch you cannot re-render.
