AspectCalc: Ratio & Crop

AspectCalc is a focused dimension toolkit for photographers, designers, video editors and anyone who works with images. Detect a ratio from any pixel size, solve a missing dimension, scale one size or build a full output set. Compare common target ratios by the visual area lost to cropping or fitting. Pick the least waste option, choose one of nine focal anchors, and copy the exact crop origin and output dimensions. Print tools convert between pixels, inches and centimetres at any density and show a clear quality rating.
