Using the correct image dimensions prevents automatic cropping and compression by the platform.
Correct dimensions
| Format | Dimensions | Notes |
|---|---|---|
| Profile photo | 400 × 400 px | Displayed as circle; PNG recommended |
| Header/Banner | 1500 × 500 px | 3:1 ratio; center subject — edges crop on mobile |
| Post image (single) | 1200 × 675 px | 16:9 ratio for feed preview |
| Post image (2 images) | 700 × 800 px each | Both images shown side by side |
| Max file size | 5 MB | PNG, JPG or WebP |
Twitter/X displays your header at different crops on desktop and mobile. Keep important content and text in the center 1000×500px of your header image.
Tips

FAQs
What happens if I use the wrong size?
The platform auto-crops or compresses your image, often losing quality or cutting off important content.
Should I resize before or after editing?
Edit first, then resize to the target dimensions as the last step.
What format is best?
JPG at 85-90% quality is best for photos. PNG is best for graphics, logos and images with text.
