Aspect Ratio Calculator

Aspect Ratio Calculator is a straightforward tool that helps you find and scale aspect ratios instantly. No complicated features. No clutter. Just enter your numbers and get results.

What it does:

Find Aspect Ratio
Enter any width and height. The app calculates the simplified ratio. For example, 1920 x 1080 becomes 16:9. 1024 x 768 becomes 4:3. 1080 x 1920 becomes 9:16. It works with any numbers, large or small, even decimals.

Scale Dimensions
Enter an aspect ratio (like 16:9 or 4:3) and a new width. The app tells you the matching height that keeps the same proportions. This is useful when resizing images, videos, or any design element without stretching or cropping.

Swap Width and Height
Tap the swap button to exchange the width and height values. Helpful when switching between landscape and portrait orientations.

Everything happens instantly on your device. The app works without an internet connection. It does not collect any data. There are no ads, no tracking, and no hidden permissions. Just open the app, enter your numbers, and get your results.

The interface is clean and easy to use with large input fields, clear buttons, and visible results. Keyboard navigation lets you move from field to field using Next and Done buttons. Tapping anywhere outside the input fields closes the keyboard.

Whether you are a video editor resizing footage, a designer maintaining proportions, a developer setting responsive dimensions, a photographer finding crop ratios, or just someone who needs quick ratio calculations, this app does the job simply and reliably.
