Instagram has expanded format support for its multi-image posts, letting users create these posts using portrait or landscape images or videos in addition to square format content. The change gives users more flexibility in choosing which content is shared on the social network, Instagram explains, although it is still limited: only one format (portrait or landscape) can be used per multi-photo post.

The restriction is in place to ensure users get a 'smooth and consistent' experience when viewing multi-content posts, says Instagram. As such, users can create a multi-image post using only portrait format, only landscape format, or only square format, but not a mixture of two or three.

The updated feature arrives today in the Instagram version 12 update for Android and iOS.
