What is an Aspect Ratio?
An aspect ratio is the proportional relationship between an image's width and height. Standard 16:9 is universal for high-definition streaming, while 9:16 dominates mobile short-form video.
Why does PPI (Pixels Per Inch) Matter?
PPI measures how tightly packed pixels are on a screen. Higher PPI produces sharper text and crisper images at close viewing distances, eliminating visible pixelation.
Responsive Scaling & Resizing
When designing responsive websites or cropping banners, locking aspect ratios prevents awkward stretching, squishing, and letterboxing artifacts.
