Discord Image Sizes: The Complete 2026 Guide
Discord displays most images tiny and circular, then enforces strict file-size caps on emoji and assets, so a great-looking source image can still fail on upload or turn to mush at 32px. Here is every dimension and limit Discord uses in 2026.
| Use | Dimensions | Ratio | Notes |
|---|---|---|---|
| Avatar (profile picture) | 128 × 128 px minimum | 1:1 | Displays as a circle at sizes down to 32px in chat, so upload 512 × 512 for crispness on profile popouts. |
| Server icon | 512 × 512 px | 1:1 | Shown as a circle in the server list at ~48px, where bold shapes beat detailed artwork. |
| Server banner | 960 × 540 px | 16:9 | Displays behind the server name at the top of the channel list; the text overlay sits at the bottom-left. |
| Custom emoji | 128 × 128 px | 1:1 | Hard 256KB file-size limit: Discord rejects larger uploads, and emoji render at just 32px in chat. |

Pro Tips
- Everything circular (avatars, server icons) loses its corners, so keep the subject inside a centered circle when designing.
- Emoji must be under 256KB: a 128 × 128 PNG almost always fits, but animated GIFs often need compression first.
- Test emoji at 32px before uploading, because fine details and thin text disappear completely at chat size.
- Server banners get darkened behind the server name; avoid important content in the bottom-left corner.
Frequently Asked Questions
Why won't Discord accept my emoji upload?
The most common reason is the 256KB file-size cap. Discord rejects anything larger, and animated GIFs hit it fast. Resize to 128 × 128 and compress the file, and the upload will go through.
What size should my Discord avatar be?
Discord requires at least 128 × 128, but uploading 512 × 512 keeps your avatar sharp on profile popouts and the new profile pages. Remember it is always cropped to a circle, so centered subjects work best.
