Switch between three modes to plan prints, calculate required pixels, or determine resulting PPI. Essential for photographers preparing work for galleries and clients.
PPI = pixels ÷ inches. When using centimeters, values are converted to inches. Aspect ratio mismatch indicates cropping or padding.
Scenario: Gallery exhibition planning with 24MP full-frame images
Image size: 6000×4000 pixels from camera
Desired print: 20×13 inches at 300 PPI for fine art quality
Result: Need 6000×3900 pixels (current image works perfectly!)
Alternative: At current pixels, max size is 20×13.3 inches at 300 PPI
300 PPI is safe for high-quality prints, while 200 PPI works well for larger sizes viewed from farther away.
Your image dimensions don't match the print dimensions—you'll need to crop the image or add borders.
Yes, but quality depends on viewing distance. Posters at 150 PPI look fine from several feet away.
Either crop your image to match the print ratio, or choose a print size that matches your image ratio.
PPI (pixels per inch) is for digital images. DPI (dots per inch) is for printers. For photography planning, use PPI.
