The correct X (Twitter) banner size is 1500×500 pixels, a 3:1 aspect ratio. Since X displays this header across both desktop and mobile layouts that crop it differently, designing with extra margin around the edges keeps your banner looking intentional on every screen.
Quick answer: Upload 1500×500 pixels (3:1). For a sharper result on high-resolution screens, design at 3000×1000 pixels and let X scale it down. Max file size is 5MB.
Key Takeaways
- 1500×500 pixels is the standard X banner size; designing at double that resolution (3000×1000) produces a sharper result on retina displays.
- X trims a strip off the top and bottom of the banner on some phone screens, so critical content should stay within the vertical center.
- Your profile photo overlaps the bottom-left corner of the banner, which needs to be accounted for during design.
- Max file size is 5MB; JPG, PNG, and GIF are all accepted.
Why 1500×500 Pixels Is the Standard
X’s header image sits at the top of your profile, stretching the full width of the page at a 3:1 ratio. A banner uploaded below 1500×500 pixels gets upscaled by X’s system, which introduces visible softness, particularly around any text or fine detail in the design. Therefore, 1500×500 is the practical floor rather than an arbitrary recommendation.
For users designing on a high-resolution monitor or exporting from design software that works in larger canvases, building the banner at 3000×1000 pixels and letting X downscale it on upload produces a noticeably crisper result than starting at the exact minimum.
How the Banner Displays Differently by Device
X doesn’t show the full 1500×500 canvas identically everywhere. The table below summarizes where cropping commonly occurs.
| Context | What Happens |
|---|---|
| Desktop profile page | Shows close to the full 3:1 banner width |
| Mobile app | Trims a thin strip off the top and bottom in some layouts |
| Profile photo overlap | Your round profile photo sits over the bottom-left portion of the banner |
As a result, keeping important text, logos, or faces centered vertically — rather than flush against the top or bottom edge — avoids losing content to either the mobile crop or the profile photo overlap.
Designing Around the Profile Photo Overlap
Your circular profile photo covers part of the bottom-left corner of the banner on both desktop and mobile. Consequently, placing a logo, headline text, or any element you want fully visible in that specific corner is a common and avoidable mistake. Our Crop Image tool lets you set the exact 1500×500 canvas and reposition elements before export, so you can plan around that overlap deliberately.
Safe Zone Checklist
- Keep key text and logos within the vertical center third of the banner.
- Leave the bottom-left corner clear of anything essential — your profile photo sits there.
- Avoid fine detail near the very top and bottom edges, which mobile layouts sometimes trim.
File Size and Format
X accepts JPG, PNG, and GIF files up to 5MB for the header image. A 1500×500 or 3000×1000 pixel JPG rarely approaches that limit once compressed reasonably well. If your source banner comes from a high-resolution export at several megabytes, our Image Compressor brings the file size down without visibly softening text or logos.
Common Mistakes
| Mistake | Why It Hurts Your Banner |
|---|---|
| Uploading below 1500×500 pixels | X upscales the image, softening detail and text |
| Placing a logo in the bottom-left corner | Gets partially covered by your circular profile photo |
| Text flush against the top or bottom edge | Can be trimmed by mobile app cropping on certain devices |
| Using a busy, detail-heavy background with text | Harder to read at the compact size the banner renders on mobile |
Expert Insight: Designing for the 3:1 Ratio Specifically
A 3:1 ratio is unusually wide compared to most social banners, which makes a single centered subject — rather than a left-to-right composition — often read better. Many banners that work well on LinkedIn or Facebook look cramped or awkwardly stretched when reused directly on X, since those platforms use closer to a 4:1 or 5.9:1 ratio instead. Consequently, designing a banner specifically for X’s 3:1 ratio, rather than reusing one built for a different platform, consistently produces a cleaner result.
Step-by-Step: Resizing a Banner for X
- Open your source photo or graphic in our Crop Image tool.
- Set the canvas to 1500×500 pixels, or 3000×1000 if you want extra sharpness on high-resolution screens.
- Position key text and logos within the vertical center, avoiding the bottom-left corner where your profile photo sits.
- Export as PNG if the banner includes text, or JPG for a photographic design.
- Compress with our Image Compressor if the file is close to the 5MB limit.
- Upload through Edit Profile on desktop or mobile, then preview how it looks with your profile photo overlapping before saving.
How X’s Banner Compares to Other Platforms
At 3:1, X’s header is wider relative to its height than most other social banners — LinkedIn’s personal banner is 4:1, and Discord’s server banner is a squarer 16:9. This means a banner built for LinkedIn or Discord generally needs to be re-cropped rather than directly reused on X, since simply stretching it to fit the 3:1 frame distorts the image noticeably.
Keeping Your Banner Readable at a Glance
Most visitors scroll past a profile header in under a second before focusing on your bio and recent posts, so a banner that communicates its message instantly tends to perform better than one that requires close reading. Brands and creators who use a short, bold statement or a single strong image rather than dense paragraphs of text on their banner generally see it register with more visitors than a text-heavy design that only makes sense after a few seconds of study. Keeping the layout simple also helps the banner age well, since X occasionally adjusts how much of the header is visible across updates to its desktop and mobile apps.
Frequently Asked Questions
What is the correct X (Twitter) banner size?
1500×500 pixels at a 3:1 aspect ratio. Designing at 3000×1000 pixels produces a sharper result on high-resolution screens.
What is the maximum file size for an X banner?
5MB. JPG, PNG, and GIF formats are all accepted.
Why does my X banner look different on mobile than on desktop?
X’s mobile layout trims a thin strip off the top and bottom of the banner in some cases, so content near those edges can be cropped differently than on desktop.
Does my profile photo cover part of the banner?
Yes, your circular profile photo overlaps the bottom-left portion of the banner on both desktop and mobile.
Can I use the same banner on X and LinkedIn?
Not directly — X uses a 3:1 ratio while LinkedIn uses 4:1 for personal profiles, so a banner built for one will look stretched or cropped on the other.
Finishing Your X Banner
Because X’s 3:1 ratio and profile photo overlap are specific to the platform, reusing a generic banner from another site is the most common source of an awkward-looking result. Use our Crop Image tool to set the exact 1500×500 canvas, and our Image Compressor to keep the final file well under the 5MB limit.
