Social Media Image Sizes: The Complete Cheat Sheet (2026)

Uploading an image with the wrong dimensions is the fastest way to get awkward crops, blurry previews or cut-off text. This cheat sheet collects the sizes that matter in 2026 — bookmark it and resize once, post everywhere.

Instagram

Placement	Size (px)	Aspect ratio
Square post	1080 × 1080	1:1
Portrait post (max reach)	1080 × 1350	4:5
Stories / Reels	1080 × 1920	9:16
Profile photo	320 × 320	1:1

The 4:5 portrait takes the most screen space in the feed — the best default for reach.

Facebook

Placement	Size (px)	Aspect ratio
Link / shared image	1200 × 630	~1.91:1
Feed photo	1080 × 1350 or 1200 × 630	4:5 or landscape
Cover	851 × 315	~2.7:1
Profile	170 × 170	1:1

YouTube

Placement	Size (px)	Aspect ratio
Thumbnail	1280 × 720	16:9
Channel banner (safe area)	1546 × 423	—
Profile	800 × 800	1:1

Thumbnails under 1280px wide get rejected; keep faces and text large — they render at postage-stamp size on phones.

TikTok

Placement	Size (px)	Aspect ratio
Video cover	1080 × 1920	9:16
Profile	200 × 200	1:1

X (Twitter)

Placement	Size (px)	Aspect ratio
Single image in timeline	1200 × 675	16:9
Header	1500 × 500	3:1
Profile	400 × 400	1:1

LinkedIn

Placement	Size (px)	Aspect ratio
Shared post image	1200 × 627	1.91:1
Banner	1584 × 396	4:1
Profile	400 × 400	1:1

Pinterest

Placement	Size (px)	Aspect ratio
Standard pin	1000 × 1500	2:3
Idea pin	1080 × 1920	9:16

Format and file size rules

1. JPG for photos, PNG for text/logos on top of solid backgrounds — text stays razor sharp in PNG. WebP is increasingly accepted and 25–35% smaller.
2. Stay under ~1 MB per image. Platforms re-compress everything anyway; huge files just upload slowly and lose quality twice.
3. Export at exactly 2× the display size for logos/text overlays (crisp on retina screens).
4. Keep faces and text in the center 80% — every platform crops edges differently per placement.

Resize, crop and compress in one pass (free & private)

The whole workflow can run in your browser — nothing uploaded:

1. Resize to the exact pixels above with the Image Resizer (aspect lock keeps proportions right).
2. Crop to the exact ratio when needed with the Image Cropper — it has 1:1, 4:5, 9:16 and 16:9 presets.
3. Compress to sane file size with the Image Compressor.
4. Convert format if needed with the JPG / PNG / WebP Converter.

FAQ-style quick answers

Do these sizes change often? A few pixels here and there yearly — the aspect ratios are stable for years. When in doubt, 1080-wide images cover 95% of cases.

Why does my image look blurry after upload? Either it was smaller than the placement size (platform upscaled it) or above ~5 MB (aggressive re-compression). Hit the recommended size and stay under 1 MB.

One image for every network? Square 1080×1080 survives everywhere; portrait 1080×1350 maximizes Instagram/Facebook but gets letterboxed on X. When reach matters, make 2 versions.
