Which aspect ratio to use
1:1 is the classic square of profile pictures and product catalogs. 4:5 is the portrait format that takes up the most space in the Instagram feed. 9:16 is the full phone screen: Stories, Reels, TikTok and Shorts. 16:9 is the format for video and YouTube thumbnails, and 3:2 is the one used by cameras and 4×6 in (10×15 cm) prints.
