📐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 Size864 × 1296pixels (px)
Standard web output and rough digital mockups.
150 DPI
Canvas Size1800 × 2700pixels (px)
High-res digital art or minimal standard print flyers.
300 DPI
Canvas Size3600 × 5400pixels (px)
The gold standard for crisp professional printing (magazines, books, commercial work).
