About this tool
3:2 is the aspect ratio of a classic 35mm film frame and most DSLR/mirrorless camera sensors, which is why it's the standard ratio behind common print sizes like 4×6 and 12×18 inches.
For AI image generation, 3:2 is a popular choice when you want a photography-style, slightly-wider-than-square composition rather than the more extreme 16:9 widescreen ratio.
