WORKED EXAMPLE
Is 4000 pixels enough for a 16-inch print?
Divide 4000 pixels by 16 inches. The result is 250 PPI, generally a strong resolution for a quality photo print.
4000 ÷ 16 = 250 PPIPrint quality

Quality and cropping by print size
| Effective PPI | Quality | Crop | |
|---|---|---|---|
| 4 × 6 | 667 PPI | Excellent | 11.1% |
| 5 × 7 | 571 PPI | Excellent | 4.8% |
| 8 × 10 | 375 PPI | Excellent | 6.3% |
| A4 | 342 PPI | Excellent | 5.7% |
| A3 | 242 PPI | High | 5.8% |
Compatibility assumes a full-bleed crop. A different image and paper aspect ratio requires cropping or white margins.
No upload is required—you can enter pixel dimensions manually.
HOW TO CHECK IMAGE DPI
Check image resolution before you print.
This private image DPI checker reads supported metadata, measures effective PPI from the real pixel dimensions and shows how large your photo can print.
- 01
Choose your image
Select a JPEG, PNG, WebP or TIFF. The browser reads the file locally; the image is never uploaded to us.
- 02
Review DPI and pixels
See pixel dimensions, megapixels and embedded EXIF, JFIF, TIFF or PNG density information when it is present.
- 03
Check every print option
Enter a print width, compare maximum sizes and check common paper formats for quality and cropping.
WHAT THE NUMBER MEANS
Effective PPI depends on print size.
The same image has a lower effective PPI when printed larger. Metadata marked “300 DPI” does not guarantee a 300 PPI print—the pixel dimensions and chosen print size determine the real value.
The report separates embedded DPI metadata from effective print PPI. Use our pixels-to-inches converter when you want a quick manual conversion.
PHOTO PRINT QUALITY
Maximum print size depends on pixels and viewing distance.
Use 300 PPI for detailed, close-viewed photographs. A quality framed print may look excellent around 200–240 PPI, while posters viewed farther away can often use 150 PPI.
| Effective resolution | Typical result | Common use |
|---|---|---|
| 300 PPI+ | Excellent detail | Photo books and close-viewed prints |
| 240–299 PPI | High quality | Framed photography |
| 150–239 PPI | Good at normal distance | Posters and larger wall prints |
| Below 150 PPI | May look soft | Distant viewing or intentional effects |
HOW IT WORKS
A clear answer, with the math to match.
Formula
effective PPI = pixel width ÷ print widthA 4000 × 3000 px image printed 10 × 7.5 inches has an effective resolution of 400 PPI and can print up to 13.3 × 10 inches at 300 PPI.
COMMON QUESTIONS
Useful context, not filler.
Is my image uploaded?＋
No. The browser reads the image dimensions on your device. The file is not sent to our server.
Why does DPI change with print size?＋
The same pixels are spread over a larger or smaller physical area. A larger print therefore has fewer pixels per inch.
What is a good effective resolution?＋
Around 300 PPI is excellent for close-viewed photo prints. 200–240 PPI is often very good, while 150 PPI can work well for posters.
Does changing a 72 DPI tag make my image higher quality?＋
No. Changing metadata alone does not create pixels or detail. Print quality depends on the pixel dimensions divided by the intended physical size.
How big can I print my photo?＋
Divide the image width and height in pixels by the target PPI. The report calculates maximum dimensions at 150, 200, 240 and 300 PPI automatically.
Why does a print size require cropping?＋
The image and paper may use different aspect ratios. Filling the paper removes part of the image; keeping the whole image instead creates margins.
