Social media image size guide

How to use this guide

Start from the shape, then the size. The shape (aspect ratio) decides whether a network crops your image; the size decides how sharp it looks. Enter your image’s width and height above to see every format it fits without cropping, then check the size column for that format.

When a network accepts a range of shapes, like Instagram’s 1.91:1 to 3:4 for feed photos, anything in between fits. When it gives one shape, like 9:16 for stories, anything else is cropped or shown with bars.

Tips that save a re-export

• Export at the recommended size, not larger. Networks compress big uploads, and an oversized file gains nothing.
• Keep text and faces away from the edges. Profile photos are shown as circles, headers are cropped differently on phones, and stories have interface on top.
• Make one master image per shape (square, 4:5, 9:16 and 16:9) rather than one per network. Most formats share one of those four.
• Save photos as JPEG and graphics with text as PNG, in the sRGB colour space.

Where these numbers come from

Each row links to its source. We used the networks’ help centres and developer documentation first. Some networks only publish sizes in their advertising specs (TikTok and X); we use those where they are the only official figures. Where a network publishes no size, we use a recent third-party guide and label it. Networks change these numbers without notice, so if a figure here disagrees with the network’s own page, trust the network.
