WhatsApp does not have strict required dimensions, but it compresses images significantly if they exceed certain sizes:
- Shared photos: WhatsApp compresses to roughly 1600px on the longest edge and applies additional compression, often reducing quality significantly. For best quality, send as a document (not a photo).
- Profile picture: 500 × 500 px minimum; displays at 192 × 192 px
- Status: 1080 × 1920 px (9:16), max 16 MB
| Type | Recommended Size |
|---|---|
| Post image | 1200 × 627 px |
| Profile picture | 400 × 400 px |
| Background / banner | 1584 × 396 px |
| Company logo | 300 × 300 px |
| Article cover image | 1200 × 644 px |
