About this tool: Aspect Ratio Calculator
Calculate a simplified aspect ratio from dimensions or use a custom/common ratio with one known dimension to calculate the other.
The output is meant to support practical visual decisions such as dimensions, color choices, contrast or layout planning.
Aspect Ratio Calculator is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
For dimensions, NexterHub scales decimal values to integers and divides both by their greatest common divisor. For a missing dimension it applies width × ratioHeight / ratioWidth or height × ratioWidth / ratioHeight.
Practical example
A 1280 px width at 16:9 gives 720 px height.
Important notes
Display, print and accessibility requirements vary, so verify the generated value in the final design environment.
