Proportional Scaler is a straightforward tool for web designers and developers. We created it because we need it!

We were fed up of opening an image editing application merely to calculate width and height of an image when scaled proportionally.

Proportional Scaler helps you to calculate the new dimensions of images and movies when scaled by their width, their height, or by a percentage value.

Scaling images:
Proportional scaler does not physically scale your image files. Proportional Scaler helps you to calculate the proper dimensions when you need to change the size of an image (or movie) on your web page. By maintaining an image's proportions, you avoid distortion, degradation and visually unappealing artefacts in your images.

Scaling movie embeds:
Movies are particularly susceptible to degradation if improperly enlarged or reduced when embedded into a web page. Proportional Scaler will help to ensure you maintain the correct proportions when defining a new width and height for an embedded movie file.

What's New in Version 1.2

Improved decimals handing:
Based on your valued feedback, we have added more intelligent decimal handling in the calculated results:

- If you do not use any decimal digits in your input values, no decimals will be displayed in the calculated values

- if you do use decimals in your input values, calculated values will have a similar number of decimal digits displayed

This gives you full and direct control of your calculated results, without resorting to preferences or settings screens.

Bug Fix:
- Fixed a bug where the ratio would not display correctly when input values less than one were entered.

Almost there

I like the idea behind the app, but it still does not work right. When I enter a width and height and a percentage with a decimal in it, I should get a new size with a decimal in it. Instead everything gets rounded up/down. Unless I am doing something wrong.

This new version is still a little off. If I enter a whole percentage everything gets rounded up instead of the actual size. For example if I enter the dimensions, 4 x 6 and enlarge it 125%, I should get in return 5 x 7.5. Instead I get 5 x 8. It shouldn't matter if I enter a dot and a zero after the whole number, I still should get the correct size. Fix the math and you've got a good program.
