Twitter/X Header Size Guide 2025
Header Image (1500x500)
The Twitter/X header image displays at 1500 x 500 pixels, giving it a 3:1 aspect ratio. This is one of the widest banner formats of any social platform, making it a challenge to design for.
The header is partially overlapped by your profile picture on the left side (the profile photo sits approximately 60 pixels from the left edge and 150 pixels from the bottom of the header). Text placed in the lower-left quadrant will be hidden behind the profile photo and name.
Profile Photo Size
Twitter/X profile photos display at 400 x 400 pixels on desktop and are cropped into a circle. Upload a square PNG at 400 x 400 pixels for the best quality. Larger files will be compressed by Twitter's servers, so uploading at exactly the required size avoids unnecessary compression.
As with all circular profile photos, center your subject and leave adequate padding around the edges. Your face or logo should occupy only the middle 60-70% of the frame.
In-Stream Photo Dimensions
In-stream photos on X now support the full 16:9 aspect ratio (1200 x 675 pixels) without cropping. This change was a major improvement for content creators who produce widescreen content for YouTube previews, photography portfolios, and cinematic screenshots.
For single image tweets, the image displays at a maximum width of 1200 pixels. For tweets with multiple images (up to four), each image is cropped to a 16:9 ratio in the gallery view. Keep your main subject centered to avoid unwanted cropping in multi-image tweets.
Card and Link Preview Images
When you share a link on X, a preview card is generated with an image. The optimal size for Twitter Card images is 1200 x 675 pixels (16:9 ratio). The image will display at a 1.91:1 ratio in the feed for summary cards, but 16:9 for large summary cards.
Use our Image Resizer to ensure your link preview images meet these exact dimensions before sharing. Twitter's card validator tool can help you test how your links will appear before you post them.
Aspect Ratio Changes on X
In 2024, X (formerly Twitter) updated its in-stream image display to support native 16:9 aspect ratios for the first time. Previously, landscape images were cropped to a 16:9 ratio, hiding the top and bottom of your frame. Now, images display in full without automatic cropping.
This change means creators can finally share widescreen content without worrying about the platform cutting off the top and bottom of their photos. However, portrait photos are still cropped to 4:5 ratio in the feed, so vertical content should be designed with that constraint in mind.

What is the best format for Twitter/X profile photos?
