What is DPI?

Dots Per Inch (DPI) measures print resolution. It determines how many tiny ink dots a printer places in one inch of paper. Higher DPI means sharper, more detailed images.

Expert Advice

💡 Professional Tips for Choosing DPI

🎯 Start with 300 DPI

For most print jobs, 300 DPI is the safe, professional choice. It provides excellent quality without excessive file sizes. Only adjust higher or lower based on specific requirements.

📏 Consider Viewing Distance

The further away a print is viewed, the lower the DPI you need. A billboard viewed from 100 feet can use 75 DPI, while a business card held 6 inches away needs 300+ DPI.

💾 File Size Management

Higher DPI means larger file sizes. At 300 DPI, an A4 print is 2480 × 3508 pixels (8.7 MP). At 600 DPI, it's 4961 × 7016 pixels (34.8 MP). Balance quality with file size.

🖨️ Printer Capabilities

Always check your printer's maximum DPI. Many consumer printers max out at 4800 × 1200 DPI, but effective print quality peaks around 300-600 DPI.
