Print Resolution Converter
Convert print/sample density among dpi, dpcm, and dpm using dots per inch as the reference.
How to use
- Enter linear resolution and choose the documentation/output notation and target among dpi, dpcm, and dpm.
Capabilities and scope
Express the same linear sample density per inch, centimeter, or meter.
How it works
dpi is the reference with 1 dpcm=2.54 dpi and 1 dpm=0.0254 dpi.
Example
300 dpi is about 118.1102 dpcm or 11,811.0236 dpm.
Useful for
- Convert 300 dpi print density to dpcm
- Compare samples-per-meter with dpi
- Normalize resolution units in documentation
Before you use it
- It does not derive image pixel dimensions or physical print size. PPI and a printer's physical dot behavior are separate concepts.

Frequently asked questions
Are dpi and ppi exactly the same?
Both can describe counts per length, but dpi is commonly output dots and ppi image pixels; device meaning should not be conflated.
