Question
What aspect ratio should I use for Reels and TikTok?
Answer
Use vertical 9:16 (1080 x 1920) for Reels, TikTok, and Shorts — it fills the screen and performs best on short-form feeds. For feed posts, 4:5 portrait or 1:1 square works well.
Design tools apply the right size automatically for each network. Compare design tools.
