What DPI should I use for printing photos?

General recommendations: 300 DPI is the standard for photo-quality prints (best quality). 240 DPI gives good quality for general photo prints. 150 DPI is acceptable for large format prints viewed from a distance. Screen display only needs 72-96 DPI.

How big can I print my photo?

Divide your image's pixel width by the target DPI to get the maximum print width in inches. For example: a 6000×4000 pixel image at 300 DPI can print 20×13.3 inches (50.8×33.9 cm). At 150 DPI it can print 40×26.7 inches (101.6×67.7 cm). This calculator automatically computes printable sizes at various DPI levels.

What print size can I get from my phone camera?

A 12MP phone photo (4000×3000 pixels) can print 13.3×10 inches at 300 DPI — excellent quality. A 48MP phone (8000×6000 pixels) can print 26.7×20 inches at 300 DPI. However, phone sensor noise and lens quality also affect large print results. Always check the image quality before ordering large prints.

❓ FAQs

What is DPI and why does it matter for printing?▼

DPI (Dots Per Inch) measures how many ink dots a printer places per inch. Higher DPI produces sharper, more detailed prints. 300 DPI is the gold standard for photo printing, delivering crisp results at normal viewing distances. Below 150 DPI, individual pixels become visible up close. Large format prints (posters, banners) can use 150 DPI since they're viewed from farther away.

How do I calculate how big I can print my photo?▼

Divide your photo's pixel width by the target DPI. Example: 6000×4000 pixels ÷ 300 DPI = 20×13.3 inches (50.8×33.9 cm). At 150 DPI: 40×26.7 inches (101.6×67.7 cm). This calculator automates all these calculations and shows print sizes across multiple DPI levels for easy comparison.

What's the difference between PPI and DPI?▼

PPI (Pixels Per Inch) describes the pixel density in a digital image file. DPI (Dots Per Inch) describes the ink dot density a printer produces. In common usage they're often used interchangeably, but technically PPI is the input (your image) and DPI is the output (printer). Most inkjet printers produce best results when the image is supplied at 300 PPI.

What print size can I get from my smartphone photos?▼

Modern smartphones capture 12MP to 48MP photos. A 12MP photo (4000×3000px) prints beautifully at 13.3×10 inches at 300 DPI. A 48MP photo (8000×6000px) can print 26.7×20 inches at 300 DPI — poster size with excellent quality. However, noise levels and lens sharpness also affect large print results.

What DPI do I need for large format printing (posters/banners)?▼

Large format DPI depends on viewing distance: Close viewing (under 3ft/1m) — 200-300 DPI; Medium distance (3-10ft/1-3m) — 100-200 DPI; Far distance (over 10ft/3m) — 50-100 DPI. A 6ft×3ft outdoor banner at 150 DPI is perfectly adequate. This calculator works for any print size and DPI combination.
