What is an aspect ratio?
Aspect ratio is the proportional relationship between an image or display screen’s width and height, written as width:height (e.g., 16:9).
What aspect ratio is used for Instagram and TikTok videos?
TikTok, Instagram Reels, and YouTube Shorts use 9:16 vertical ratio (1080x1920px), while Instagram posts use 1:1 square or 4:5 vertical.
How do I calculate missing dimension from aspect ratio?
Multiply or divide your known width/height by the ratio fraction. For 16:9, height = width * (9 / 16).
