Quick Answer

Enter your image dimensions in pixels and the target DPI to instantly see the physical print size in inches, centimeters, or millimeters. Essential for print design preparation.

How It Works

This tool uses the mathematical relationship: Physical Size = Pixels / DPI. By inputting your image resolution and your desired print density, the tool calculates the corresponding physical dimensions across various metric and imperial units.

Frequently Asked Questions

What DPI should I use for printing?

300 DPI is the gold standard for high-quality print — photos, magazines, brochures, and art prints. 150 DPI works for large-format prints (posters, banners) viewed from distance. 72 DPI is screen-only and will look pixelated on paper.

How do I calculate the print size from pixels?

Divide your pixel dimensions by the DPI. A 3000×2400 pixel image at 300 DPI will print at 10×8 inches. At 150 DPI, the same image prints at 20×16 inches but with half the detail density.

What's the difference between DPI and PPI?

DPI (dots per inch) refers to printer output — physical ink dots on paper. PPI (pixels per inch) refers to digital screen density. They're often used interchangeably, but for print preparation, DPI is the correct term. The tool handles both.

Can I increase DPI to make a small image print larger?

No. DPI is a measure of density, not total information. A 1000×1000 pixel image contains the same data whether you set it to 72 DPI or 300 DPI — the print just becomes smaller at higher DPI. You cannot create detail that doesn't exist in the original pixels.

What size should my image be for a standard 6×4 inch print?

At 300 DPI, you need 1800×1200 pixels minimum. A 12-megapixel camera produces more than enough resolution. For smaller wallet prints (3.5×2.5 inches at 300 DPI), you need 1050×750 pixels.
