Image Resolution Planner

Choose inches or centimeters, physical width and height, and a target PPI to calculate required raster dimensions and compare common print-density targets.

Plan pixels from physical output

Start with the print size you want and a target PPI. This is the reverse of the Image Print Size Calculator.

This calculates raster dimensions from physical size × PPI. It does not guarantee a printer, paper, viewing distance, or source image can deliver a particular perceived quality.

Pixel, megapixel & memory budget

Translate a print size and PPI target into pixel dimensions, megapixels and approximate uncompressed RGB/RGBA memory.

Browser-local limits

Canvas-based export is browser dependent. PNG is broadly available; JPEG/WebP quality and support can vary, and metadata may not be preserved through canvas re-encoding.
