Why Aspect Ratios Matter
Aspect ratio defines the proportional relationship between width and height. Preserving the aspect ratio prevents images and videos from appearing stretched, squashed, or distorted.
Aspect Ratio Formula
(original height / original width) × new width = new height
Example: resizing a 1920 × 1080 image to 640 pixels wide results in a height of 360 pixels.
