    • Frequently Asked Questions

    What DPI should I use for printing?

    300 DPI for high-quality prints (photos, brochures). 150 DPI for magazines. 72-96 DPI for large format (billboards, banners) viewed from distance. Newspaper = 72 DPI. The farther the viewing distance, the lower DPI needed.

    How do I calculate pixels from print size and DPI?

    Pixels = Inches × DPI. For 8×10 inch at 300 DPI: 8×300 = 2400 pixels wide, 10×300 = 3000 pixels tall. For metric: convert mm to inches first (÷25.4), then multiply by DPI.

    What is bleed in printing?

    Bleed is extra image area beyond the trim line, typically 3mm (0.125 inch). It ensures no white edges after cutting. For an A4 page with bleed, design at 216×303mm instead of 210×297mm. Total pixels increase accordingly.

    What is the difference between DPI and PPI?

    PPI (pixels per inch) describes screen/image resolution. DPI (dots per inch) describes printer output. A 300 PPI image prints well at 300 DPI. They're often used interchangeably, but technically DPI refers to physical printing dots.
