DPI Calculator
Calculate print size from image resolution and DPI. Find required pixels for any print size, estimate file sizes, and check if your image meets professional print standards (300 DPI).

How to Use This Calculator
- Enter your image width and height in pixels.
- Enter the desired DPI (300 for professional print quality).
- See your print size in inches and quality assessment instantly.
- Use Required Pixels tab to work backwards — enter desired print size to find minimum pixel resolution.
- Use Scan Settings to estimate file size when scanning a document.
- Use the Professional tab for megapixels, bleed area, and common print size feasibility.
Formula
Print Width (in) = Image Width (px) ÷ DPI
Required Pixels = Print Size (in) × DPI
File Size (MB) = Width × Height × 3 bytes ÷ 1,048,576
Example
Image: 3000×2000px at 300 DPI → Print size = 3000÷300 × 2000÷300 = 10"×6.67". File size = 3000×2000×3÷1048576 = 17.2 MB uncompressed.
Frequently Asked Questions
- DPI (dots per inch) measures print resolution — the number of ink dots per linear inch. Higher DPI = sharper print. 300 DPI is the standard for professional photo printing. 72-96 DPI is for screen display only.
- 300 DPI for professional photo prints and brochures. 200 DPI for standard home printing. 150 DPI for large format prints viewed from a distance. 72-96 DPI is screen resolution only — photos will look pixelated when printed.
- Print size = pixel dimensions ÷ DPI. A 3000×2000px image at 300 DPI prints at 10"×6.67". At 150 DPI it prints at 20"×13.33" — same image, lower quality.
- Bleed is extra image area (usually 0.125" on each side, 0.25" total) that extends beyond the trim line. It prevents white edges when the paper is cut. Add 0.25" to both dimensions for full-bleed printing.
- No — PPI (pixels per inch) refers to screen displays and describes pixel density on a monitor. DPI refers specifically to physical print output and describes ink dot density. This calculator is for printing; use the PPI Calculator for screen displays.
