Twitter Image Sizes 2026: Header, Post, Profile & Ad Dimensions (X)

TL;DR: The Short Answer

Here is the one thing most 2024-era guides get wrong: X (Twitter) now prioritizes portrait 3:4 images in the feed — they display taller and take more space than the old 16:9 landscape. If you still post 16:9 by default, you are giving up screen real estate. Beyond that, the core sizes are stable: header/banner/cover photo 1500 × 500 pixels (3:1), profile photo 400 × 400 (circle crop), single tweet images accept any ratio from 2:1 to 3:4 — use 1200×1600 (3:4) for maximum space, 1600×900 (16:9) for landscape, or 1080×1080 (1:1) square, link/og:image cards 1200×627 (1.91:1), and ads support 1.91:1, 1:1, 4:5, 2:3, 16:9, and 9:16.

Export as sRGB JPG under 5 MB (8 MB for Premium). Keep all header text in the center band — roughly 60 px crops off the top and bottom, and your circular profile photo covers the lower-left. This guide covers every surface — header, profile, single and multi-image tweets, link cards, video, and ads — with crop maps and safe zones. The official X Help Center profile guide and Adobe’s X/Twitter image sizes guide confirm these numbers.

The 2026 X (Twitter) Image Size Cheat Sheet

Header / Banner / Cover Photo: 1500 × 500

Your Twitter header (also called banner or cover photo) is the single most-missized element on the platform. The official X Help Center recommends 1500 × 500 pixels, a 3:1 aspect ratio. Upload JPG, PNG, or GIF — but animated GIFs do not work on headers or profile photos; they render as a static first frame.

Two crops ruin headers. First, X trims roughly 60 px off the top and 60 px off the bottom on some displays and browsers, so the visible band is closer to 1500 × 380. Second, your circular profile photo overlaps the lower-left corner, covering anything you put there. Design for a center safe zone: keep all text, logos, and faces within the middle ~70% horizontally and the middle ~75% vertically, and never put anything important in the lower-left. Solid brand colors, subtle gradients, and simple patterns always survive cropping; busy photos with faces in the corners do not. Hootsuite’s social media image sizes guide and Influencer Marketing Hub’s X image sizes 2026 both flag this crop trap.

Profile Photo: 400 × 400, Circle Crop

Upload your profile photo at 400 × 400 minimum (800 × 800 is better for sharpness). It displays as a circle around 200 px on your profile and much smaller (40–48 px) in the feed. Keep your face centered and away from the edges — anything in the corners gets cut off by the circle. Use a real headshot with a clean background; if you need to remove a distracting backdrop, our background removal methods or ecommerce product photo editing team handle it cleanly. Max file size is 2 MB, and animated GIFs are not supported.

Single Tweet Image: Why 3:4 Beats 16:9 in 2026

This is the biggest change in recent years. X displays any single image with an aspect ratio between 2:1 (wide) and 3:4 (tall) in full, without cropping. Within that range, taller images take more vertical space in the feed — and more space means more attention. So:

• 3:4 portrait (1200 × 1600): the tallest allowed, the most feed space. Best for portraits, quotes, infographics, and anything you want to stop the scroll.
• 1:1 square (1080 × 1080): safe middle ground, looks identical on desktop and mobile, never crops.
• 16:9 landscape (1600 × 900 or 1200 × 675): classic for screenshots and wide scenes, but displays noticeably smaller than 3:4 now.
• 2:1 wide (1200 × 600): the widest accepted without crop. Anything wider gets cropped to 2:1.

Minimum resolution X accepts is low, but anything under 1200 px wide looks soft on retina displays. Max file is 5 MB for free accounts, 8 MB for X Premium. After resizing to your target pixel dimensions, a light sharpening pass keeps text and edges crisp through X’s compression.

Multi-Image Tweets: How X Crops 2, 3, and 4 Photos

When you attach more than one photo, X arranges them in a grid and crops each tile — so composition matters.

• 2 images: side by side, each roughly 7:8 (slightly portrait). Keep subjects centered; left/right edges get trimmed.
• 3 images: one large image on the left (roughly 7:8) plus two stacked images on the right (each roughly square). The first image you attach is the large one.
• 4 images: 2 × 2 grid, each tile roughly 1:1 or 7:8.

Because every tile is cropped toward a near-square, upload square (1080 × 1080) or near-square images for multi-photo tweets — wide 16:9 shots get butchered in the grid. Put the most important photo first, since it gets the largest tile in a 3-photo post and the top-left position in a 4-photo grid.

Link Cards and og:image: 1200 × 627

When you paste a link into a tweet, X pulls the og:image from the page and shows it as a link card — a 1.91:1 rectangle below your text. Design your website’s og:image at 1200 × 627 pixels (or 1600 × 840, same ratio). If your og:image is missing or too small, X shows a plain text link, which gets far fewer clicks. Put the article title or a strong visual on the image — link cards are clickable, and a compelling thumbnail doubles click-through. Buffer’s social media image sizes guide covers og:image specs across all networks.

Video on X: Sizes and Length

• Resolution: minimum 1280 × 720 (720p); recommended 1920 × 1080 (1080p). Max accepted is higher, but 1080p is the sweet spot.
• Aspect ratios: 16:9 (landscape), 1:1 (square), or 9:16 (vertical). Vertical 9:16 (1080 × 1920) takes the most mobile feed space, matching the 3:4 still-image logic.
• Length: up to 140 seconds (2:20) for standard accounts; X Premium subscribers can upload up to ~3 hours.
• File size: up to 512 MB. MP4 or MOV. Add captions — most viewers watch with sound off.

X Ads: Image and Carousel Specs

Paid posts support more ratios than organic.

• Single image ad: 1.91:1 (1200 × 627), 1:1 (1080 × 1080), 4:5 (1440 × 1800), 2:3 (1080 × 1620), 16:9, or 9:16. Max 5 MB, JPG/PNG. The 4:5 and 2:3 portrait formats take the most feed space.
• Carousel ad: 2–6 cards, each 800 × 800 (1:1) or 800 × 418 (1.91:1). Headline up to 70 characters per card.
• Video ad: MP4 or MOV, 6-second looping GIF or standard video, 16:9 recommended (1280 × 720), up to 512 MB.

The official X Business ad specs page lists every format in detail.

Export Settings for Sharp X Graphics

• Color space: sRGB. Adobe RGB and ProPhoto shift dull on X.
• Format: JPG quality 80–90% for photos; PNG for text-heavy graphics, logos, and flat colors.
• File size: under 5 MB (free) / 8 MB (Premium). Aim for 200–500 KB for feed images.
• Pixel dimensions: export at exactly the target size. Never upscale — it blurs.
• Sharpen after resize: light unsharp mask (Amount 80–120%, Radius 0.5–1 px) compensates for X’s compression. Our photo editing guide covers the full export workflow.
• Text: keep it large and high-contrast. In a 1500×500 header, text under 24 px is unreadable.

5 Common Twitter Image Mistakes

1. Posting 16:9 by default. In 2026, 3:4 portrait takes far more feed space. Switch your default template to 1200 × 1600.
2. Putting text in the header corners. 60 px crops off top and bottom, and the profile photo covers the lower-left. Keep everything centered.
3. Uploading wide 16:9 images in multi-photo tweets. They get cropped to near-square tiles. Use square for multi-image posts.
4. Forgetting og:image on your website. Shared links without a 1200 × 627 og:image show as plain text and get ignored.
5. Oversized files. A 10 MB photo compresses harder and looks worse than a properly exported 400 KB one.

Frequently Asked Questions

Final Verdict

Twitter’s sizes are stable except for one important shift: the feed now rewards tall 3:4 images, so retire the old 16:9 default. Keep your header at 1500 × 500 with everything centered, profile photo at 400 × 400, single tweets at 1200 × 1600 (or 1080 × 1080 for multi-photo), link cards at 1200 × 627, and export in sRGB under 5 MB. Design for the two header crops — top/bottom trim and the profile-photo overlap — and your graphics will look sharp on every device.
