aspectRatio features a fixed calculator for common square and non-square pixel aspect ratios. It also features a Custom Calculator with presets and "Not-Divisible by 16" alerts.

Custom calculations begin with the user defining a source aspect ratio. Proportionate relative ratios are then returned based on user defined "width" and/or "height" inputs.

The RETURN key triggers calculations in both modules. Clicking through the "Mode more...

What's New

Version 2.3:

The link to the developer's web site is wrong. It should be:


Also, the platform is wrong. This is a universal PPC/Intel binary.

This is a great little app. It's simple and easy to use.

You can calculate both vertical and horizontal values in the custom values area.

It's very handy.

I'm using version 1.6t for Tiger.

Is there no chance for a 10.4.11 version? I really need an app like this.

While it's a neat little tool, I'm puzzled as to why it is only possible to enter a value in the box for horizontal.

This is going to be a permanent fixture in my dock. Great work!

Naoh: I think you can put in a custom vertical. If you click on the bottom right "dot" button it brings up a window with more extensive options.
