Social Media Image Sizes

Which ratio should you deliver?

YouTube rows on this page come from https://support.google.com/youtube/answer/6375112. Last verified 2026-10-06. If a placement is missing, we did not have an official URL we were willing to cite.

Standard video upload: 1920×1080 (16:9). YouTube recommended upload encoding lists 16:9 frame sizes including 1920×1080. 720p upload: 1280×720 (16:9). Same recommended encoding table includes 1280×720. 4K upload: 3840×2160 (16:9). Recommended encoding table includes 3840×2160. Custom video thumbnail: 1280×720 (16:9). YouTube help: thumbnail 1280×720, under 2 MB, JPG/GIF/PNG. Feed photo (square): 1080×1080 (1:1). Instagram help documents square 1:1 as a supported feed crop. Feed photo (portrait): 1080×1350 (4:5). Instagram help: portrait feed crops as tall as 4:5. Stories and Reels: 1080×1920 (9:16). Full-screen Stories/Reels use a 9:16 frame on typical phone canvases. In-feed video (ads creative spec): 1080×1920 (9:16). TikTok Ads creative specifications list 9:16 vertical video at 1080×1920. Feed image (square): 1080×1080 (1:1). Meta Ads Guide lists 1:1 as a primary feed image ratio. Stories: 1080×1920 (9:16). Meta Ads Guide lists 9:16 for Stories placements. In-timeline photo: 1200×675 (16:9). X help on posting photos and media; 16:9 is a common timeline display crop. Confirm live crop in the composer. Share image (landscape): 1200×627 (1.91:1). LinkedIn marketing/help image size articles list ~1.91:1 share images (1200×627 class). Standard pin: 1000×1500 (2:3). Pinterest creative guidance commonly specifies 2:3 pins (e.g. 1000×1500).

Convert from a 16:9 master

Most cameras and desktop editors still start at 16:9. To reach 9:16, crop 607×1080 or pad 1920×3414 from a 1920×1080 source.

Open any table row in the calculator to set the width or the height in pixels. That is faster than retyping a cheat sheet.

What this page will not claim

Safe-zone UI chrome, bitrate caps and file-type limits change often. We list ratio and pixel size only when the cited help page states them.

Ads placements can differ from organic placements. The Meta and TikTok rows used here are the public ads/help specs, labelled as such.

Notes that apply only to Social Media Image Sizes

This chart is a union of the cited platform rows, not a third-party “2026 cheat sheet.” If a network is missing (Snapchat, Threads, WhatsApp), we did not have an official URL we were willing to pin to a last_verified date.

Open-in-calculator icons pre-fill Resize so you can test a width immediately. Last verified dates stay on each source row, not on the build clock.

Use social media image sizes to decide the export before you edit, not after. A campaign usually needs a square or 4:5 feed still, a 9:16 story, and sometimes a 16:9 player or a 2:3 pin. Make those from one master and keep the master. Each network page on this chart states the shape we could cite, so a missing row means we left it out rather than guessing a pixel pair.
