Why POD DPI is not one number
A mug is held at 12 inches. A 24×36 poster is seen from four feet. A t-shirt print is somewhere in between and has to survive halftone or DTG screening. Close-view products (mugs, cases, notebooks, fine-art 8×10) should be built at 300 DPI. Large posters and canvas often look correct at 150 DPI because of viewing distance and, on canvas, surface texture.
Several large catalogs have published 150 DPI as a practical target for posters and apparel art, with 300 DPI preferred for small hard goods. Those figures change. Always open the current template. PrintFit does not scrape vendor sites and does not claim to be their spec sheet.
Design at native pixels
If the shirt box is 12×16 inches at 300 DPI, start a 3600×4800 pixel canvas. Do not design at 1000×1000 and “add DPI” on export. For type-heavy designs, stay at 300 even when the catalog allows 150. Then confirm the file with this checker or the print quality table.
Questions people actually ask
- What resolution for a 24×36 poster?
- At 150 DPI: 3600×5400 pixels (19.4 MP). At 300 DPI: 7200×10800 (77.8 MP), which few cameras produce uncropped. 150 DPI is the usual poster plan.
- Do I need 300 DPI for a t-shirt?
- A 12×16 print at 150 DPI is 1800×2400. That can look fine for photographic art. Logos and small text are safer at 300 DPI (3600×4800).
