Make an X post with AIX (Twitter) design tips that matter
Knowing the pixel sizes is half the battle. Here's what separates designs that get engagement from designs that don't.
Default to 16:9 or square
1200x675 and 1080x1080 both display uncropped in the timeline. Only go taller when the extra height earns its space.
Design multi-image posts as one set
Two-image grids crop each photo to 7:8 and four-image grids crop to 2:1. Keep every focal point centered so nothing gets cut.
Caption your videos
Most X videos autoplay on mute. Burn in captions or on-screen text so the post works silently.
Check it in dark mode
A huge share of X runs dark mode. Transparent PNGs and dark text can vanish, so test your graphic on both backgrounds.
