Twitter (X) Header Size: 1500x500 (2026)
The Twitter (X) header size is 1500x500 pixels at a 3:1 aspect ratio. One catch: your profile picture and bio overlay the bottom of the header on mobile, so keep anything important in the top 350 pixels.

The numbers you need, ready to copy into your canvas.
Keep text and logos in the top 350 pixels of the header. On mobile, your profile photo and bio cover most of the bottom strip.
Or skip the safe-zone math and design your X header with AI. It lands at exactly 1500x500 with your message clear of the overlay.
Twitter banner size (same as the header)
Banner, header, cover: all three words point at the same image. The rebrand to X changed the logo, not the frame, so the twitter banner dimensions are still 1500x500 pixels at a 3:1 ratio. If a design tool asks you for x banner dimensions or twitter cover dimensions, 1500x500 is the answer every time.
There are really only two twitter banner sizes worth keeping. 1500x500 is the native upload and what X serves to most people. 3000x1000 is the same artwork at 2x, and it holds up better on retina laptops and high-DPI phones because X re-compresses whatever you hand it. Going under 1500x500 is the one thing to avoid: X upscales small files, and the softness shows the second someone opens your profile.
Color deserves a second of thought, because your banner sits against both themes. Artwork that ends in white edges looks like a floating rectangle for anyone browsing in dark mode, and near-black artwork disappears in light mode. Run your color all the way to the edge of the canvas so there's no visible seam, keep text at strong contrast against whatever sits behind it, and let one brand color carry the whole 3:1 strip instead of three colors competing for it.
The twitter banner specs themselves are short. JPG, PNG, or GIF, up to 5MB, RGB color. PNG is the safer pick when the banner carries a wordmark, a logo, or thin type, because X compresses JPG hard and the edges of letters are the first thing to go fuzzy.
Every number in one line: 1500x500 pixels, 3:1, RGB, JPG or PNG, under 5MB, with your message inside a centered 1300x350 area.
Twitter banner specs and the mobile vs desktop crop
Uploading at the right size is the easy half. The other half is knowing what X does with the image afterward, because desktop and mobile frame your banner differently and neither one shows all 1500x500 pixels the way you designed them.
File format and file size
X accepts JPG, PNG, and GIF for headers, with a 5MB cap. Most well-exported banners land under 1MB, so the cap is rarely what stops you. Use PNG for anything with text, a logo, or flat color blocks, and JPG for photo-led banners where compression is harder to spot. GIF uploads go through, but don't build a design around motion: the header renders as a still frame.
Desktop crop
On desktop your banner sits above the profile in a wide column and shows close to the full 3:1 frame. Your profile picture overlaps the bottom-left as a 200x200 circle with a border, which takes out roughly the left 250 pixels of the bottom strip. That corner should hold background only, never a logo or a line of copy.
Mobile crop
Mobile is the tighter one. X keeps the full width and trims around 60 pixels off the top and bottom of the frame to fit the narrower profile card, then stacks your avatar, display name, and bio over the lower part of what's left. Anything you care about has to live in the middle band, clear of both edges.
The safe zone in numbers
Put both crops together and one rectangle works everywhere: 1300x350 pixels, centered horizontally, sitting in the upper two-thirds of the canvas. Keep your headline, logo, and any URL inside it, give the very top and bottom edges a little breathing room for the mobile trim, and treat the bottom 150 pixels and the outer 100 pixels on each side as decoration that plenty of people will never see.
Check it before you publish
Two minutes of checking saves a re-upload. Open your own profile on a phone and on a laptop, switch X between light and dark mode, and look at what your avatar covers in each one. Then zoom out until the banner is about the size of a business card, roughly what someone sees while skimming, and see whether the message still reads. If the text is only legible at full size, it's too small or too thin for a 3:1 strip. Bumping the type up and cutting a word or two usually fixes both problems at once.
Sizing the rest of your social art in the same session? The OG image size (1200x630) is a different frame again, and it's the one that shows up when someone shares your site on X.
Where the safe zone sits
Profile picture and bio overlay the bottom-left. Keep critical content in the top 350 pixels.

Design a Twitter header with AIX (Twitter) design tips that matter
Knowing the pixel sizes is half the battle. Here's what separates designs that get engagement from designs that don't.
Design for the top 350 pixels
Mobile users see most of the top of the banner. The bottom 150 pixels are usually behind your profile picture and bio.
Avoid stock cliches
Mountains and laptops are everywhere on X. A bold typographic banner with your tagline reads as more authentic.
Refresh for launches
If you're shipping a product or speaking at an event, swap your banner the week of. It's free real estate everyone sees when they land on your profile.
PNG over JPG for graphics
X compresses JPG aggressively for banners. PNG preserves text sharpness better.
Frequently asked questions
1500x500 pixels at a 3:1 aspect ratio.
The same as the header: 1500x500 pixels at a 3:1 aspect ratio. Banner, header, and cover all describe the same image. Keep your text and logo inside a centered 1300x350 safe zone so your profile picture and bio don't cover them on mobile.
X crops headers slightly on mobile and overlays your profile photo and bio at the bottom. Always keep your most important text and visuals in the top 350 pixels of the 500-pixel-tall canvas.
You can, but X displays it on a black or white background depending on the viewer's theme. Test in both light and dark mode before publishing.
5MB. Most well-compressed banners come in under 1MB.
Yes. The header dimensions (1500x500) haven't changed since the rebrand from Twitter to X.
