Free maximum print size calculator
Find your image’s maximum uncropped print dimensions.
Use the final pixel width and height to calculate the largest physical output at 300, 240, 200 or 150 PPI. This answers how large one specific image can print before cropping.

When to use it
Start with the result you need
This calculator is most useful when one part of the print specification is known and another needs to be checked.
Check an image from a client
See whether the supplied artwork reaches the requested dimensions before production begins.
Plan large-format output
Compare 200 and 150 PPI options for work intended to be viewed from a greater distance.
The calculation
How it works
Maximum physical size is calculated independently for both sides: print inches = pixels ÷ PPI. A 6000 × 4000 pixel image measures 20 × 13.33 inches at 300 PPI.
The result is uncropped. Choosing a paper size with a different aspect ratio removes pixels and can reduce the effective resolution of the final composition.
Need to calculate total pixel count, exact aspect ratio or uncompressed RGB size instead? Use the megapixel calculator.
Quick reference
Choosing a useful print-density target
There is no single PPI that fits every production method. Start with the printer’s requirement and consider viewing distance.
| Density | Typical use | Viewing pattern | Planning note |
|---|---|---|---|
| 300 PPI | Photos, books, fine detail | Close viewing | Strong default target |
| 240 PPI | Quality photo and art prints | Close to normal | Often visually excellent |
| 200 PPI | Medium wall prints | Normal room distance | Check provider requirement |
| 150 PPI | Posters and larger displays | Farther viewing | Subject detail matters |
| 100 PPI | Large-format signage | Several metres away | Use only with provider approval |
Printer DPI describes ink-dot placement and is not the same measurement as image pixels per inch.
Check the numbers
6000 × 4000 px at 300 PPI
The maximum uncropped dimensions are 20 × 13.33 inches, or approximately 50.8 × 33.87 centimetres.
4500 × 3000 px at 240 PPI
The image measures 18.75 × 12.5 inches before any crop or bleed is applied.
3000 × 2000 px at 150 PPI
The file can fill 20 × 13.33 inches at poster density, assuming the production provider accepts 150 PPI.
Before you export
Common mistakes to avoid
Reading only the DPI metadata
A metadata value such as 72 DPI does not set the maximum size. The actual pixel dimensions are the essential input.
Forgetting that cropping removes pixels
The calculated size uses the full image. Recalculate with the post-crop dimensions for a different paper ratio.
Treating a threshold as a guarantee
Compression, focus, noise and sharpening also affect visible quality even when the PPI calculation looks sufficient.

How large can a 6000 × 4000 pixel image print?
A 6000 × 4000 pixel image is approximately 20 × 13.33 inches at 300 PPI or 25 × 16.67 inches at 240 PPI before cropping.
Can I print larger than the calculated size?
Yes, if a lower effective PPI is acceptable for the production method and viewing distance. Ask the printer which minimum density they recommend.
Should I use the dimensions before or after editing?
Use the final exported pixel dimensions. Cropping, rotation, perspective correction and resampling can all change the available pixels.
