How to use Photo Print Size & DPI Checker
Drop a photo into the checker. FileFlip reads its pixel dimensions and, when the file stores one, its embedded DPI, then shows the largest print you can make at your chosen quality target without upscaling the image. The table shows the DPI each common print size — 4×6, 5×7, 8×10, 11×14, 16×20, A4 and US Letter — would get from that photo, graded from excellent to too low. Everything is measured on your device; the photo is never uploaded.
Frequently asked questions
What DPI do I need for printing photos?
300 DPI is the standard for photo prints and looks sharp at normal viewing distance. 200 DPI is good for most prints, 150 DPI is acceptable for posters and large formats viewed from further away, and anything below 100 DPI looks pixelated.
What's the difference between DPI and PPI?
PPI (pixels per inch) is the pixel density of a digital image; DPI (dots per inch) is how many ink dots a printer lays down. The terms are used interchangeably in everyday printing talk, and this tool reports the pixels-per-inch your photo provides at a given print size.
How do I work out print size from pixels?
Divide the pixel dimensions by the target DPI. A 3000 × 2400 px photo prints at 10 × 8 inches at 300 DPI, and at 20 × 16 inches at 150 DPI — the bigger the print, the lower the DPI.
Why does it say my DPI isn't stored in the file?
Most photos from phones, cameras and websites don't embed a DPI value, because DPI only becomes meaningful once you choose a print size. The checker calculates the real resolution from the pixel count instead.
Can I print bigger than the size shown?
Yes, but the image will be upscaled and may look softer. For a bigger print, start from a higher-resolution original or resize the photo first.
