Enter width and height to get a simplified ratio (for example 16:9), a decimal ratio, common ratio names, and optional scaled dimensions for a target width or height.
Enter dimensions to simplify the aspect ratio.

Use the Aspect Ratio Calculator form near the top of this page. Enter the values you know, run the tool, and review the results panel. You can change inputs and run it again. Processing stays in your browser and is not uploaded to Utilnivo servers.
Example: open Aspect Ratio Calculator, enter a realistic set of inputs for your situation, and note the primary result. Change one input—such as an amount, rate, or option—and compare how the output changes so you can choose a scenario that fits your needs.
Second example: try edge cases that matter for your task—such as zero values, a different unit system, or a second file—and confirm the tool shows a clear result or a helpful validation message.
Enter width and height in any unit. The calculator simplifies the ratio with the greatest common divisor, names common ratios like 16:9, and can scale to a target width or height while keeping the same proportions.
This tool runs in your browser for convenience. Results are estimates or transformations based on the inputs you provide and may not cover every edge case.
Width and height are divided by their greatest common divisor, so 1920×1080 becomes 16:9.
