Aspect-ratio & print-size matcher
See whether your image fits the print shape—and how much a fill crop removes.
Choose your measurements and calculate to see the result.
A visual size estimate. Verify the actual artwork, frame, mat, glazing, hardware, wall and manufacturer specifications before buying or arranging a display. Dimensions alone do not guarantee fit.
Compare proportions before you order a print.
A 4 × 6 photo is 2:3 in portrait; an 8 × 10 is 4:5. Enlarging one to the other changes the shape. “Fill” makes the image large enough to cover the destination, cropping the excess. “Fit” keeps the whole image and leaves blank space.
Worked example: 4000 × 3000 pixels
At 300 pixels per inch, the uncropped image is 13⅓ × 10 inches. For a landscape 10 × 8 print, filling the rectangle crops 6.25% of its area; fitting the entire image leaves 6.25% blank destination area. Rotate your target dimensions to match your intended orientation.
The calculator uses the source numbers as pixels for the PPI output. If you enter a simple ratio such as 4 and 3, ignore that physical-size result. 300 PPI is an example input, not a quality guarantee; printers have their own requirements and resampling policies.
Mat overlap can hide additional content after the print crop. Check both the photo-size guide and the mat window.
