An aspect ratio calculator is a web-based utility that computes new dimensions for digital media while maintaining the original proportions. It ensures that images or videos scale perfectly without stretching, squeezing, or distorting. Core Features
Proportional Scaling: Enter the original dimensions (width and height) and define one new target dimension; the tool automatically calculates the missing value.
Platform Presets: Includes quick-click dimensions optimized for major platforms like Instagram (1:1, 4:5, 9:16), YouTube (16:9), and Facebook.
Universal Math: Works seamlessly across multiple digital measurement formats, including pixels, centimeters, and inches.
Zero Overhead: Operates entirely in-browser with no login required, no software downloads, and no ads. Underlying Formulas
The calculator operates using standard algebraic cross-multiplication to solve for missing variables:
New Height=New Width×(Original HeightOriginal Width)New Height equals New Width cross open paren the fraction with numerator Original Height and denominator Original Width end-fraction close paren
New Width=New Height×(Original WidthOriginal Height)New Width equals New Height cross open paren the fraction with numerator Original Width and denominator Original Height end-fraction close paren Common Digital Presets
