To convert millimeters to Procreate pixels, this calculator determines the canvas pixel dimensions needed to achieve a target DPI for your physical print size. Procreate sets canvas size in pixels and DPI in the Custom Canvas dialog.
Enter the mm value
Enter the physical dimension in millimeters — the size you want your artwork to be when printed. For example, 210 × 297 mm for an A4 print or 148 mm for A5 width.
Select the DPI
Choose the DPI. Procreate's Custom Canvas dialog lets you set DPI independently. For print-quality artwork, use 300 DPI. For screen-only digital art, 72 or 150 DPI saves memory and increases the maximum layer count.
Read the pixel result
Read the pixel result. Enter this as the Width or Height in Procreate's Custom Canvas dialog along with your chosen DPI. Procreate will confirm the physical print size matches your target.
Procreate's maximum canvas size depends on your iPad model's GPU. Higher pixel dimensions reduce the available layer count. A 300 DPI A4 canvas (2480 × 3508 px) may support fewer layers than a 150 DPI version (1240 × 1754 px). Plan your DPI based on both print quality needs and layer requirements.
