How to do it
- Open the Image Resizer and load your banner art.
- Set custom dimensions 1500 × 500.

Constraints to know

Questions
What size is a Twitter / X header in 2026?
1500 × 500 px (3:1), max 5 MB, JPG or PNG.
Why is my X header blurry?
Uploading under 1500 px wide forces upscaling. Export at 1500 × 500 from a larger source.
Where does the profile picture sit on X?
Overlapping the bottom-left of the header — keep that area clear.
