What it means for a Dubai business
Portrait posts take more of the screen than squares, so they hold attention longer in the feed. Since Instagram’s profile grid moved to taller rectangular tiles, 4:5 also crops less on your profile.
Reels and Stories fill the phone at 9:16. Keep text and faces away from the very top and bottom, where the app places buttons and captions.
Example
An interior studio used to post square crops of wide rooms. It switches to 4:5, framing each room vertically, which shows more of the ceiling height that villa owners care about.
Common mistake
Posting horizontal photos and letting Instagram crop them. The best part of the room ends up at the edge. Frame for the format when you shoot.
