Frequently Asked Questions

What DPI do I need for good quality prints?

300 DPI is the industry standard for high-quality photo prints. 150 DPI is acceptable for large posters viewed from a distance. 72 DPI is standard for web and screen display only.

How do I calculate print size from pixels?

Divide the pixel dimensions by the DPI. A 3000×2000 pixel image at 300 DPI prints at 10×6.67 inches. At 150 DPI, the same image prints at 20×13.33 inches but with less sharpness.

What is the difference between metric and imperial units?

Metric units (meters, kilograms, liters) are based on powers of 10 and used by most countries. Imperial units (feet, pounds, gallons) are primarily used in the US, UK, and a few other countries.

How do I convert meters to feet?

Multiply meters by 3.28084 to get feet. For example, 10 meters = 32.8084 feet. Conversely, multiply feet by 0.3048 to get meters.
