About Ratio Calculator
A ratio compares two quantities and shows their relative sizes. Ratios are used in many areas including mathematics, design, photography, video production, and cooking. This calculator helps you solve ratio problems, find missing values in proportions, and simplify complex ratios.
How Ratios Work
Ratios are typically expressed in the form A:B, where A and B are numbers. For example, a 16:9 ratio means that for every 16 units of width, there are 9 units of height. Ratios can be simplified by dividing both numbers by their greatest common divisor (GCD).
Common Aspect Ratios
Here are some standard aspect ratios used in different fields:
| Ratio | Simplified | Common Uses |
|---|---|---|
| 4:3 | 1.33:1 | Standard definition TV, older computer monitors |
| 16:9 | 1.78:1 | HDTV, widescreen computer monitors |
| 16:10 | 1.6:1 | Some computer monitors, tablets |
| 21:9 | 2.33:1 | Ultrawide monitors, cinematic displays |
| 1:1 | 1:1 | Square images, Instagram posts |
How to Use This Calculator
This calculator has two main functions:
- Ratio Solver: Enter a ratio (A:B) and a value to calculate the missing dimension (width from height or height from width).
- Ratio Simplifier: Enter a ratio to find its simplest form by dividing both numbers by their greatest common divisor.
Practical Applications
Ratio calculations are essential for:
- Web Design: Maintaining consistent aspect ratios for responsive images
- Photography: Cropping images to standard print sizes
- Video Production: Ensuring proper scaling between different resolutions
- Printing: Calculating dimensions for posters and banners
- Cooking: Scaling recipes up or down while maintaining proportions
