Calculate the pixel dimensions for a 10 × 12 inch print
Choose the intended physical size
Enter 10 for width and 12 for height, select inches, and choose the physical-size-to-pixels direction. These inputs define a size interpretation; they do not change an image file. Use the print provider’s actual requirement when choosing the intended PPI.
Apply the formula
At 300 PPI, multiply each inch edge by 300. The output is 3000 × 3600 pixels. For centimeters, divide each edge by 2.54 before multiplying. Therefore 25.4 × 30.48 cm at 300 PPI gives the same pixel dimensions.
Check the reverse direction
Switch to pixels-to-physical-size and enter 3000 × 3600 at 300 PPI. The result is 10 × 12 inches. A 5000 × 5400 file at the same PPI represents about 16.67 × 18 inches. The display rounds long decimal results for readability.
Separate PPI from file editing
The calculator does not resize artwork or add a DPI metadata tag. It also does not assess the visible quality of the image. Use a separate image workflow to prepare the required pixels and inspect the actual saved file before uploading it to a print service.
Avoid a quality guarantee
A numeric match cannot guarantee print sharpness. Existing detail, text edges, compression and enlargement matter, and printer DPI is a different property from image PPI. Review the actual artwork and the receiving service’s pixel, format and print-area requirements together.
Try and verify the workflow
10 inches at 300 pixels per inch needs 3000 pixels on that edge. A 5000-pixel edge at 300 PPI represents about 16.67 inches.
