AspectCalc: Ratio & Crop

Detect and solve ratios, build batch size sets, compare the least waste crop or fit, set focal anchors, and calculate print dimensions with exact pixel results.

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.

WHAT YOU CAN DO

• Detect and simplify a ratio from any whole pixel dimensions
• Solve a missing width or height from any ratio
• Use quick formats such as 16:9, 4:5, 1:1 and 2.39:1
• Scale a size by percentage while preserving its ratio
• Build and copy a batch set of output sizes
• Rank common targets by the least crop or fit waste
• Place a crop using nine focal anchors
• Calculate print dimensions and effective pixel density
• Save reusable ratios and calculation history
• View personal usage insights
• Export PDF spec sheets, CSV data and a validated local backup
