Frequently Asked Questions
What DPI do I need for printing?
300 DPI is the gold standard for photo-quality prints viewed up close. 150 DPI is acceptable for posters viewed from a distance. 72 DPI is screen-only resolution.
How many pixels do I need for an 8×10 print?
For a sharp 8×10" print at 300 DPI, you need 2400×3000 pixels (7.2 megapixels minimum). Most modern smartphone cameras exceed this.
Does higher DPI always mean better quality?
Above 300 DPI, the human eye cannot perceive improvement at normal viewing distances. For large prints viewed from farther away, 150 DPI is often sufficient.
