📐Pixel Dimensions

Digital canvasses rely on exact pixel densities (DPI/PPI) to match physical print dimensions. Graphic designers standardly request assets rounded to the nearest whole pixel at these crucial breakpoints:

72 DPI
Canvas Size708 × 1001pixels (px)

Standard web output and rough digital mockups.

150 DPI
Canvas Size1476 × 2085pixels (px)

High-res digital art or minimal standard print flyers.

300 DPI
Canvas Size2952 × 4170pixels (px)

The gold standard for crisp professional printing (magazines, books, commercial work).
