How this calculator works
Choose a local image to read its original pixel dimensions. The file stays in browser memory; the calculator does not upload, store, or transmit it.
How to use the Image Print Size Calculator
- Choose a JPG, PNG, WebP, AVIF, or GIF from your device.
- Select the output PPI required for the job.
- Compare the calculated physical size with the print size you intend to order.
Worked example
A 6000 × 4000 pixel photo can print at 20 × 13.33 inches at 300 PPI, or 40 × 26.67 inches at 150 PPI.
Accuracy note: The calculator reads only the real pixel dimensions. Embedded resolution metadata does not create additional image detail.
Frequently asked questions
Is my image uploaded?
No. FileReader reads the image locally in your browser and no network request is made.
What files are accepted?
JPG, PNG, WebP, AVIF, and GIF files up to 25 MB are accepted. SVG is blocked intentionally.
What size can I print at 300 PPI?
Upload the image and the calculator will use its exact width and height to show the maximum size.
Choose the largest sensible print, not simply the largest number
The same image produces different physical dimensions at different output densities. Use 300 PPI as a conservative close-viewed photo target, 240 PPI when the lab accepts it, and 150 PPI mainly for larger work viewed from farther away.
| Image pixels | 300 PPI | 240 PPI | 150 PPI |
|---|---|---|---|
| 3000 × 2000 | 10 × 6.67 in | 12.5 × 8.33 in | 20 × 13.33 in |
| 4000 × 3000 | 13.33 × 10 in | 16.67 × 12.5 in | 26.67 × 20 in |
| 6000 × 4000 | 20 × 13.33 in | 25 × 16.67 in | 40 × 26.67 in |
| 8000 × 6000 | 26.67 × 20 in | 33.33 × 25 in | 53.33 × 40 in |
Megapixels do not determine the crop
A 6000 × 4000 image has a 3:2 aspect ratio. It fits a 12 × 8 or 18 × 12 print without cropping, but a 10 × 8 print is 5:4 and will lose part of the long edge unless borders are added. Use the actual width and height in pixels; a megapixel total alone does not reveal the aspect ratio.
What this tool cannot judge
- Focus, motion blur, compression artifacts, noise, sharpening, and subject detail.
- Whether the aspect ratio matches a frame or whether the lab will crop the edges.
- A provider's bleed, color profile, file-format, or minimum-resolution rules.
No image is uploaded. This page answers one question: “how large can I print this file?” If the physical size is already fixed, use the PPI Calculator to check effective resolution. If you have not checked focus, compression, crop, and the printer's requirements, follow the five-minute image print-readiness check.
