i was tired of trying to figure out which resolutions i should use for my games via trial-and-error, so i made this tool. if you are making a pixel-art game with integer scaling, this should help you find game screen sizes that either exactly match common resolutions or match close enough that the screen borders are acceptably small. this tool takes an aspect ratio, finds every resolution near that ratio, checks to see what it neatly scales into, and tabulates the info below. enter your desired parameters and click “generate.”
Enter one or more aspect ratios (W:H), comma‑separated.
e.g. 0.005 = ±0.5%
This tolerance helps detect "close" multiples.
