Composition check
ISO paper dimensions are specified in millimeters. The pixel numbers round upward from the exact millimeter conversion; use the actual trim size specified by your lab.

Or enter dimensions below. Artwork stays on your device.
Centered crop calculation, orientation as entered. Swap print width/height for landscape. Meeting PPI does not prove sharpness or good composition.
Before you promise this size
- Use original pixel dimensions, not the DPI metadata label.
- Check the calculated crop percentage and visually inspect text and subject edges.
- Open the actual exported file and proof it at the intended size.
- Check delivery bytes separately; uncompressed pixels do not predict JPEG size.
300 PPI is a planning target, not a quality guarantee. A blurred or artificially enlarged source may still look poor.
