Exactly what I wanted. Good work.

Except two things…

1. It’s not very attractive.

2. I wish I could have a little box pop up showing an actual image at the dimensions—or at least the ratio—I’ve typed in.

Other than that, great!

Simple, but very useful

One of the maddening things when designing is stopping to work out your maths: "What's the 16:9 width when I only have 185 pixels in height?" This solves that. Quickly.

For the price, just put it in your toolkit.

(I'd give it five stars, but the UI needs a little more love.)
