Pixel Print Planner
Print planning guide
Start with the actual pixel dimensions
Find width and height in your image editor’s image-size dialog or the file’s Details or Info panel. Use the dimensions of the final exported image, after any edits or crop—not a camera’s megapixel label or the size of a thumbnail.
Enter those two whole numbers, choose the paper dimensions, and set your own target PPI. Calculate to compare the same source image in two ways. Load example uses 4000 × 3000 pixels on a 10 × 8 inch sheet. Nothing is uploaded.
Fit keeps everything. Fill trims the edges.
Fit scales the whole image proportionally until it touches two paper edges. Any unused space becomes centered borders. Fill scales proportionally until the paper is covered, then removes equal amounts from opposite sides. Neither option stretches the image.
A 4000 × 3000 image on 10 × 8 inch paper fits at 10 × 7.5 inches: the top and bottom borders are each 0.25 inch, and density is 400 PPI. Filling the same sheet retains a 3750 × 3000 pixel rectangle at 375 PPI, cropping 6.25% of the original image area. At a 300 PPI target, that sheet requires 3000 × 2400 pixels.
PPI is a planning ratio, not a quality rating
Here, PPI means source image pixels per printed inch. Divide pixels by physical inches to calculate it. Printer DPI describes the printer’s output dots, a different quantity; this tool does not model those dots or translate PPI into a printer setting.
The default target of 300 PPI is an editable comparison value, not a universal requirement. A 6000 × 4000 image on a 12 × 8 inch sheet gives 500 PPI with neither crop nor borders. Changing a resolution label without changing pixel dimensions does not change this calculator’s result.
Choose for the picture and the destination
For artwork with a signature near an edge, start with Fit and consider how a mat or frame opening may cover the border. For a borderless photo, inspect the Fill crop allowance before ordering—especially when faces or text sit near an edge.
For a square source on rectangular paper, you must choose borders or a crop. If orientation is wrong, swap the source and paper independently; rotating one does not rotate the other. Confirm the lab’s actual print area, automatic crop settings, bleed, and frame opening separately. This planner uses only the dimensions you enter.
Common questions
Why do I see fractional retained pixels? The crop rectangle is ideal geometry; an editor or lab must choose actual pixel boundaries. Why is my screen ruler different? The schematic is proportional, not life-size, and screen size does not determine printed size.
Can this fix a low-resolution image? No. It does not resample, sharpen, upscale, edit, or create an image file. Can I move the crop? No: both layouts are centered. For an off-center composition, make the crop in an editor and calculate again with the new dimensions.
What the estimate leaves out
The model assumes a rectangular image, rectangular paper, uniform scaling, and no stretching. It does not inspect image detail, focus, compression, color, viewing distance, paper, printer behavior, bleed, or lab tolerances.
Use full-size proofs or advice from your print provider when the result matters. Inputs are limited to 1–1,000,000 whole pixels per side, 0.01–1,000 inches (or up to 2,540 centimeters) per paper side, and 0.01–10,000 target PPI. Values are calculated at full numerical precision; displayed results are rounded to two decimal places, so a very small crop or border may display as zero.
