OG Image Size Guide 2026: Perfect Dimensions for Every Platform
May 22, 2026 · 7 min read
Don't guess at OG image dimensions. The wrong size means your social preview gets cropped, downgraded to a thumbnail, or rejected entirely. Here are the exact pixel sizes every platform actually uses in 2026 — pulled from current platform docs and rendering behavior we've verified.
The universal answer: 1200×630
If you make one OG image and stop, make it 1200×630 pixels at 1.91:1 aspect ratio. This single dimension renders cleanly on Facebook, LinkedIn, Slack, Discord, and Twitter/X. It's the size every modern platform's preview component is built around.
Keep file size under 8 MB (Facebook's limit). PNG or JPG both work; PNG if you need text crispness, JPG if file size matters.
Platform-by-platform breakdown
| Platform | Recommended | Aspect ratio |
|---|---|---|
| 1200×630 | 1.91:1 | |
| Twitter/X | 1200×600 | 2:1 |
| 1200×627 | 1.91:1 | |
| Slack | 1200×630 | 1.91:1 |
| Discord | 1200×630 | 1.91:1 |
Why text gets cropped
Every platform applies a different safe-zone within the 1.91:1 frame. Twitter occasionally crops the bottom 30 pixels. LinkedIn squeezes by 3 pixels at top and bottom. The fix: keep all critical text and logos at least 90 pixels from any edge.
FAQ
What is the standard OG image size?
1200×630 pixels. This is the dimension the original Open Graph spec recommends and the one Facebook, LinkedIn, and most platforms render cleanly without cropping.
Does Twitter/X use 1200×630?
Twitter accepts 1200×630 but officially recommends 1200×600 for Summary Card (Large Image). The 30-pixel difference rarely causes visible cropping, but pure-1200×600 is safer if your design has tight margins.
What aspect ratio should I use?
1.91:1 is the standard Open Graph aspect ratio (1200×630 simplifies to roughly 1.905:1). Stay within ±5% of that ratio and every platform renders without distortion.
Will small OG images still work?
Facebook accepts as small as 200×200 but downgrades the preview to Summary Card style — a small thumbnail next to the title. For the full hero-card preview, you need at least 1200×630.
