Image aspect ratio is the proportional relationship between width and height. Common ratios include 16:9 (widescreen), 4:3 (standard), 1:1 (square for social media), and 3:2 (photography). Maintaining aspect ratio prevents distortion when resizing.
Large images are the #1 cause of slow websites. Resizing images to their display dimensions reduces file size, decreases load time, saves bandwidth, and improves SEO rankings. For example, displaying a 4000px image in a 400px container wastes 96% of the data transferred.
