Make a square tweet image

Square is the format that works everywhere without thinking about it. Instagram, Facebook, LinkedIn and X all display 1:1 uncropped in the feed, so one export covers every destination when you do not want to make a decision per platform.

This page keeps the background plain white rather than a gradient, which is the right choice when the image will be reposted, embedded or printed and you do not want a colour scheme fighting whatever surrounds it.

Questions

Is square still a good format?
Yes, for ordinary feed posts and for one file used in several places. Vertical wins only on Stories, Reels and TikTok.
Why white rather than a gradient?
White composites cleanly onto any page or slide. A gradient is a design choice that can clash with its surroundings.
What size is the export?
1080 by 1080, the standard square size every platform accepts uncropped.
