Q. What's the best image size for X (aka Twitter)

In this article we list the best image and Ad sizes to use for the X social media platform.

For X (formerly Twitter) image posts, the best image size depends on the type of post you’re making:

Recommended Image Sizes

Single image post:

• 1200 x 675 px (16:9 ratio)
• Minimum size: 600 x 335 px
• Max file size: 5MB (photos), 15MB (GIFs)

Profile images:

• 400 x 400 px (appears as a circle in feed)

Header/cover image:

• 1500 x 500 px

Multiple images (in a collage):

• 2 images: both at 7:8 ratio
• 3 images: left is 7:8, right two are 4:7 stacked
• 4 images: all at 2:1 ratio

Best Practices

• Stick to 16:9 ratio for single-image posts to avoid awkward cropping.
• Keep important content (text, faces, logos) centered since X crops previews.
• Use JPG or PNG for photos/graphics and GIF for animations.

👉 The safest all-purpose size is 1200 x 675 px (16:9) for standard posts.
