How Large Can You Print It? DPI Calculator
Upload a photo and its pixel size is detected automatically — or type the dimensions yourself. Instantly see the largest sharp print size at photo, poster and wall-viewing quality, and check DPI for every standard frame size.
| Standard size | DPI your photo gives | Verdict |

DPI is simply pixels ÷ inches. 300 DPI suits prints viewed up close; posters viewed from a few steps back look excellent at 180–240 DPI, and large wall pieces are fine at 150 DPI. If a size's shape does not match your photo's shape, the lab will crop one edge — the table flags that.
Set your canvas or camera to at least these pixels before you design or shoot — enlarging afterwards cannot add real detail.
Free Print Size Calculator — Pixels, DPI and Sharp Prints
Every print question comes down to one division: pixels ÷ DPI = inches. A 6000 × 4000 photo prints at 20 × 13.3 inches at 300 DPI, or 40 × 26.7 inches at 150 DPI. This calculator runs that division both ways — from your photo to its largest sharp size, and from a frame size back to the pixels you need — so you never pay a lab for a blurry enlargement.
🖼️ Photographers
Confirm the largest sharp print from a camera file before sending it to the lab — including whether a crop is needed for the frame shape.
🛍️ Etsy & print sellers
Check that a digital download prints cleanly at 8 × 10, 11 × 14, A4 or poster sizes before listing it, and size new canvases correctly from the start.
🎨 Designers
Plan flyers, menus, cards and posters with the right DPI and bleed before exporting final artwork.
🔒 Fully private
An uploaded photo is read only to measure its pixel dimensions. It is never sent to a server or stored anywhere.
What DPI should you use?
300 DPI is the standard for anything viewed up close: books, portfolios, small fine-art prints and photo albums. 240 DPI covers most posters. 150 DPI is honest for wall pieces viewed from a few steps back, and large banners can go to 100 DPI because nobody reads them from arm's length. Chasing 300 DPI on a poster is usually wasted effort — and wasted file size.
Frequently Asked Questions
A 6000 × 4000 file gives 20 × 13.3 inches at 300 DPI, or 40 × 26.7 inches at 150 DPI. For a wall piece viewed from a distance, the 150 DPI figure is the honest one.
2400 × 3000 pixels at 300 DPI. For A4 you need about 2480 × 3508 pixels, and for 16 × 20 inches about 4800 × 6000 pixels.
Frames have fixed shapes (4 × 6 is 3:2, 8 × 10 is 4:5). If your photo's shape differs, one edge must be cropped or the print gets white borders. The size table flags mismatches so you can crop intentionally instead of letting the lab decide.
