Twitter/X header image specifications
The recommended header size is 1500×500 pixels at a 3:1 aspect ratio. This is the size X displays on desktop profiles. On mobile, the header renders differently — it's cropped from the center, showing roughly the middle third of the banner.
Maximum file size is 5 MB. As with any web image, a well-compressed JPG at 150–300 KB looks identical to an uncompressed upload and loads faster.
Accepted formats are JPG and PNG. JPG is preferred for photographic banners. PNG works if you need sharp text or graphics overlaid on the banner.

- Safe zone: keep important content in the center third
Designing for the safe zone
The most important design consideration is that your profile photo overlaps the bottom-left corner of the banner on desktop. Any text, logos, or faces placed in that area will be hidden behind your circular profile picture.
On mobile, only the center portion of the banner is visible — roughly 1500×500 cropped to about 1500×250 from the vertical center. Design your banner so the key message and visuals sit in the center third.
Avoid placing critical text near the edges. X's interface may crop slightly differently across devices and screen sizes. A centered composition with generous padding on all sides survives every viewport.
How to prepare your banner on Irreva
Start with a high-resolution source image — at least 1500px wide. If your source is a photo or graphic at a different aspect ratio, use the Image Cropper to set a 3:1 ratio and position the crop over the area you want visible.
Resize to exactly 1500×500 pixels using the Image Resizer. Enter both dimensions explicitly to ensure the output matches X's specifications precisely.
Compress with the Image Compressor at 80–85% quality. A 1500×500 banner at this quality typically produces a 100–250 KB JPG — well under the 5 MB limit and sharp on all screens.
Preview the result by uploading it to your X profile. Check both desktop and mobile views. If important content is clipped, adjust the crop and re-export.
Banner design tips
Keep it simple. A header banner is a background element, not a billboard. One clear message, a clean image, or a brand color gradient works better than a cluttered collage.
Use high-contrast text if you include words. The banner sits behind your profile info and tweets — busy backgrounds make text hard to read. A semi-transparent overlay behind text improves legibility.
Update seasonally or for campaigns, but maintain visual consistency with your profile photo and brand colors. A header that clashes with your profile picture looks unintentional.
If you're not a designer, a solid brand color with your logo centered in the safe zone is perfectly professional. Not every banner needs a photograph.
Twitter header vs other platform banners
Each platform has different banner dimensions. LinkedIn backgrounds are 1584×396. Facebook covers are 820×312. YouTube banners are 2560×1440 with a complex safe zone. Don't reuse the same image across platforms without resizing and re-cropping.
Use the Image Cropper with the correct aspect ratio for each platform, then the Image Resizer for exact pixel dimensions. The workflow is the same — only the numbers change.
Maintain a master version of your banner at the highest resolution you need, then crop and resize down for each platform. This preserves quality better than upscaling a small image.
