Aspect Ratio Calculator

Calculate aspect ratios from dimensions (e.g., 1920x1080 to 16:9) or find missing dimensions using a known aspect ratio.

Instructions

This tool helps with aspect ratios in three ways: 1. **Find Aspect Ratio:** Enter both **Width** and **Height** to calculate the simplified ratio (e.g., 16:9) and decimal ratio. 2. **Find Height:** Enter **Width** and **Aspect Ratio** (e.g., '16:9' or '1.777') to calculate the corresponding Height. 3. **Find Width:** Enter **Height** and **Aspect Ratio** to calculate the corresponding Width. Ensure you provide the correct combination of inputs for the calculation you need.

Enter the width. Provide Width & Height to find Ratio. Provide Width & Ratio to find Height.
Enter the height. Provide Width & Height to find Ratio. Provide Height & Ratio to find Width.
Enter the desired aspect ratio (like '16:9', '4:3' or a decimal like '1.777'). Used with Width OR Height to find the other dimension.
