AspectCalc: Ratio & Crop

Aspect ratio & resize math

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

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 * Prepare six format delivery sets with exact source crops and final output pixels * Rank common targets by the least crop or fit waste * Place a crop using nine focal anchors * Plan exact safe rectangles with independent horizontal and vertical margins * Check megapixels, estimated memory, and a chosen pixel limit before export * Calculate print dimensions and effective pixel density * Plan print bleed, trim, safe areas and full canvas pixels * Save reusable ratios and calculation history * View personal usage insights * Export PDF spec sheets, CSV data and a validated local backup FREE AND PRO Ratio solving, detection and single size scaling are available free. AspectCalc Pro is a one time in app purchase that unlocks ratio comparison, crop and fit planning, focal anchors, batch size sets, print tools and professional exports. There is no subscription and no account is required. PRIVATE BY DESIGN Saved ratios, calculations and backups remain under your control on your device or in a file location you choose. AspectCalc includes no advertising, analytics or tracking.
