Social Media Specs
Social Media Image Sizes
This is the table I keep open when briefing designers. It covers the aspect ratios that actually matter, because most platforms accept a range of pixel dimensions but only crop cleanly at specific ratios. Build to the ratio first, then export at a safe pixel width.
| Platform | Placement | Aspect ratio | Recommended pixels |
|---|---|---|---|
| Square feed post | 1:1 | 1080 x 1080 | |
| Portrait feed post | 4:5 | 1080 x 1350 | |
| Landscape feed post | 1.91:1 | 1080 x 566 | |
| Feed image | 1.91:1 or 1:1 | 1200 x 630 or 1080 x 1080 | |
| Feed image | 1.91:1 or 1:1 | 1200 x 627 or 1080 x 1080 | |
| X (Twitter) | In-stream image | 16:9 | 1600 x 900 |
| Standard Pin | 2:3 | 1000 x 1500 |
| Platform | Placement | Aspect ratio | Recommended pixels |
|---|---|---|---|
| Stories and Reels | 9:16 | 1080 x 1920 | |
| Stories and Reels | 9:16 | 1080 x 1920 | |
| TikTok | In-feed video | 9:16 | 1080 x 1920 |
| YouTube | Shorts | 9:16 | 1080 x 1920 |
| Vertical video | 9:16 | 1080 x 1920 | |
| Snapchat | Snap Ads | 9:16 | 1080 x 1920 |
| Platform | Asset | Aspect ratio | Recommended pixels |
|---|---|---|---|
| Profile photo | 1:1 | 320 x 320 | |
| Page profile photo | 1:1 | 170 x 170 displayed | |
| Personal profile photo | 1:1 | 400 x 400 | |
| Personal background banner | 4:1 | 1584 x 396 | |
| Company page banner | 4:1 | 1128 x 191 displayed | |
| X (Twitter) | Header image | 3:1 | 1500 x 500 |
| YouTube | Channel banner | 16:9 safe area | 2560 x 1440 |
| YouTube | Video thumbnail | 16:9 | 1280 x 720 |
Notes
Design once at 1080 x 1350 and you cover more surface than any other single size. The 4:5 portrait crop is the tallest ratio Instagram accepts in feed, it downsizes cleanly to 1:1 for LinkedIn and Facebook, and it takes up more vertical screen on mobile than a square, which is most of what feed real estate is worth.
Every platform re-compresses your upload. Export at the recommended pixel width rather than 4x that width, use sRGB, and avoid fine one pixel lines or heavy gradients, which are what compression artifacts attack first. If a brand asset has thin type, thicken it for social rather than fighting the encoder.
Safe areas matter more than canvas size on vertical formats. On Stories and Reels, keep text and logos roughly 250px clear of the top and 400px clear of the bottom of a 1920px tall canvas, because captions, profile chrome and the interaction rail sit there. On the YouTube channel banner, only the central 1546 x 423 region is guaranteed visible across devices.
Platforms change these values without announcement and often A/B test crops in the app before documenting them. Treat this table as a working default and confirm against the platform's own help centre before a large production run.
Frequently asked questions
Should I upload the largest file I can?
No. Uploading a 6000px wide file just means the platform resizes it with its own algorithm instead of yours. Export at or near the recommended dimension so you control the downsample, and keep files under a few megabytes.
What single size should I use if I only make one asset?
1080 x 1350 (4:5) for static feed, and 1080 x 1920 (9:16) for anything vertical. Those two cover the majority of organic placements across Meta, LinkedIn and TikTok.
Do these sizes apply to paid ads too?
Mostly, but ad placements add their own constraints such as text overlays, safe zones and file size caps. Check the ad platform spec page for the network you are buying on.
