Twitter (X) Banner Size in 2026: Exact Dimensions, Safe Zones, Common Mistakes
The number you came for: 1500 x 500 pixels. The part that actually ruins banners: the profile photo overlap and the mobile crop. Both are solved below, with the exact pixels.
The spec (verified August 25, 2026)
- → Banner: 1500 x 500 px, 3:1 ratio, max 5MB, JPG or PNG
- → No animated GIFs; headers are static on every tier
- → Profile photo: 400 x 400 px, circular crop
- → Keep text and logos in the central band; the bottom-left dies under your avatar
The exact X banner size in 2026 is 1500 x 500 pixels (3:1), max 5MB, JPG or PNG. The spec has not changed in years; what keeps changing is how the banner gets cropped across devices, which is why banners that looked perfect in the design tool arrive with the tagline buried under the profile photo.
The Full Spec, One Table
| Banner (header) size | 1500 x 500 px |
| Aspect ratio | 3:1 |
| Max file size | 5 MB |
| Formats | JPG or PNG (no animated GIF) |
| Displays at (desktop) | ~1200 x 400 px |
| Profile photo | 400 x 400 px (circular crop) |
| Danger zone | bottom-left corner (profile photo overlap) + top/bottom edges (mobile crop) |
| Safe zone | central ~1200 x 330 band |
The Safe Zone: Where Your Design Survives
Think of the 1500 x 500 canvas as three zones:
The dead zone (bottom-left). Your circular 400 x 400 profile photo overlaps here on the rendered profile. Anything in roughly the left 420 px of the bottom half is gambling with being covered.
The crop zone (top and bottom edges). Phones shave horizontal slices off the banner; different devices shave differently. Keep 60-80 px at the top and bottom free of anything essential.
The safe zone (the central band). The middle ~1200 x 330 area survives every device we test. Put the text, the logo, the faces, the CTA there. Decoration can bleed to the edges; meaning stays in the band.
Practical workflow: design at exactly 1500 x 500, put a 400 px circle guide in the bottom-left and 70 px guides top and bottom, and preview on your own phone before calling it done. Every design tool preset (Canva, Figma) ships the 1500 x 500 frame; the guides you add yourself.
The Five Mistakes That Ruin Good Banners
1. Uploading the wrong resolution. Smaller images get upscaled into blur; giant images get compressed into mush. Export exactly 1500 x 500.
2. Fine print. X compresses. Small text becomes fuzz, especially in JPGs. If it matters, make it big; if it is decorative, it can be small.
3. Key content bottom-left. The single most common failure: the tagline sits exactly where the avatar renders. Check the rendered profile, not the export.
4. JPG for graphics. Flat colors and text belong in PNG; photos belong in JPG around quality 80. The wrong format either blurs edges or blows the 5MB cap.
5. A banner that says nothing. The banner is the largest pixel area on your profile - prime space in the 3-second follow decision. Social proof, what you do, or your best hook belong there; abstract gradients are a wasted billboard.
Every Other X Image Size You Will Ask About Next
Profile photo: 400 x 400 px, circular crop, JPG/PNG. In-feed images: 16:9 (1600 x 900) renders clean as a single image; squares work; verticals get cropped in-feed. Link/card previews: 1.91:1 (1200 x 628) is the safe target for sites you share. And if you are producing video instead, our X video guide has the 2026 length and size limits per tier.

What is the Twitter (X) banner size in 2026?
1500 x 500 pixels, a 3:1 aspect ratio, maximum 5MB, in JPG or PNG. That spec has been stable for years and is still current as of August 2026. Upload at exactly 1500x500 - X scales anything else and scaling is where blur comes from.
Why does my X banner look blurry?
Three usual causes: you uploaded a smaller image and X upscaled it, you uploaded a huge file and X compressed it hard, or your image has fine text that survives neither. Fix: export exactly 1500x500 as a PNG under 5MB for graphics/text, or a quality-80 JPG for photos, and keep text large.
What part of the banner gets covered by the profile picture?
The circular profile photo overlaps the bottom-left corner of the banner, and mobile screens crop slices from the top and bottom edges. Keep anything that matters - text, logo, faces - in the central band and away from the bottom-left. Rule of thumb: center your key content in the middle ~1200x330 area.
Can I use an animated GIF as my X header?
No. X headers must be static images (JPG or PNG; a GIF gets flattened to its first frame). Animated profile assets are not supported for headers on any tier.
What size should my X profile picture be?
400 x 400 pixels, displayed as a circle. Design for the circle: keep faces or logos centered so the corner crop takes nothing important. Same JPG/PNG guidance as the banner.
