How to Use

Simply enter two whole numbers into the fields above. For example, if you enter 1920 and 1080, the tool will find the Greatest Common Divisor (GCD) and divide both numbers by it to give you the simplified version, which in this case is 16 : 9. This is extremely useful for maintaining proportions when resizing images or mixing ingredients.

Frequently Asked Questions

What is a ratio? +
A ratio is a mathematical comparison of two numbers that indicates how many times one value contains or is contained within the other. It is usually written with a colon (:) or as a fraction.
Why should I simplify a ratio? +
Simplifying a ratio makes the relationship between the numbers easier to understand and communicate. "2 : 1" is much more intuitive than "450 : 225," even though they represent the exact same proportion.
What are common aspect ratios? +
In digital media, common ratios include 16:9 (Widescreen video), 4:3 (Standard TV/Monitor), 1:1 (Square/Instagram post), and 9:16 (Vertical video/TikTok).
Can I use decimals? +
This specific tool is designed for whole numbers. If you have decimals, multiply both by 10 or 100 first to turn them into whole numbers before simplifying (e.g., convert 1.5 : 2 into 15 : 20).
