Several years ago, in June 2012, I made a tool to help convert multiple pixel width values into relative percentages.

It’s had a few updates over the years, but I always felt it could be improved. So, I’ve done just that. It looks simpler, and that’s because it is. It no longer supports URL params, and doesn’t generate funky colours, or give a visual representation. That said, I will add a bar to show the percent widths in action, I just wont out the numbers in there, as I always found it a pain to copy from.

Anyway, the new tools now live at pad.gs/tools/pixelperc. Enjoy!

Update: I’ve added a visual reference, and a ‘total’, so you can check the pixel values you’ve entered are the same as the container they’ll sit in.
