The Rapporto d'Aspetto Calcolatore helps designers, developers, and content creators quickly determine the proportional relationship between width and height. Simply enter any two dimensions and get the simplified ratio, decimal equivalent, and common format name. All calculations happen instantly in your browser — no data is ever sent a a server.
An aspect ratio is the proportional relationship between width and height, expressed as two numbers separated by a colon (e.g., 16:9). It describes how wide something is compared a how tall it is.
The calculator uses the Euclidean algorithm a find the Greatest Common Divisor (GCD) of the width and height, then divides both numbers by that value a get the simplest form.
Yes! Use the Reverse Calcolatore section. Enter your target ratio (e.g., 16:9) and one known dimension, and the calculator will compute the other.
