Twitter (X) Image Size Guide 2026

Any twitter image size guide worth using starts with the shape that avoids awkward cropping in the timeline: 1200x675 pixels, a 16:9 ratio, for a standard in-feed image post. Square 1200x1200 also displays cleanly, especially in multi-image posts, but extreme aspect ratios, very tall or very wide, get cropped in ways that can cut off the part of the image you actually wanted seen.

X photo dimensions 2026, by placement

Placement	Dimensions	Aspect ratio
In-feed single image	1200 x 675	16:9
In-feed square	1200 x 1200	1:1
Profile photo	400 x 400	1:1 (displays as a circle)
Header image	1500 x 500	3:1
Max file size	5MB	JPG, PNG, or WebP

Why extreme aspect ratios get cropped awkwardly in the timeline

X's timeline reserves a fixed amount of vertical space for image previews regardless of the source image's actual proportions. A very tall image gets cropped top and bottom to fit that space; a very wide panorama gets cropped at the sides. Either way, whatever sits at the edges of an extreme ratio is the first thing to disappear. Staying within 16:9 to 1:1 keeps your image inside the zone X actually displays without cropping.

Multi-image posts behave differently

Posting two, three, or four images together changes the layout entirely. Two images each display around 506x506px side by side. Three images show one larger image alongside two smaller ones. Four fill a grid, each roughly 253x506px. Because the crop happens automatically based on count, keeping the important part of each image centered matters more than hitting an exact dimension when posting multiple images at once.

Profile and header images

Your profile photo displays as a circle everywhere on X, in the timeline, search results, and reply threads, so keep your subject centered with margin on all sides; anything near the corners gets clipped by the circular crop. Your header image spans a wide 3:1 banner at the top of your profile; since a chunk of it can sit behind your profile photo and bio on some layouts, avoid putting essential text or faces in the center-left area where overlap is most likely.

Format choices that hold up under compression

PNG holds up better for graphics, screenshots, logos, or anything with text and sharp edges, since it avoids the soft compression artifacts JPG can introduce around fine lines. JPG is the better choice for photography, where its smaller file size doesn't cost much visible quality. Either format, staying under the 5MB limit avoids extra processing time on upload.

Checking your image before you post

A social post preview shows how an image will actually crop in the timeline before it's live, and the social media image resizer handles converting a source image to the right dimensions for feed posts, headers, or multi-image sets.
