Free business tools
Convert a pixel measurement to physical size using its DPI or PPI.
These tools are intentionally practical. They help founders, operations heads and managers frame a requirement before contacting a development team.
Plan before you build
All results are rough planning estimates. For production software, we review process, data, users, security and integrations before quoting.
Calculators are often the first step toward a useful internal tool: quotation builders, stock planners, project estimators, payroll helpers, school fee calculators or customer self-service portals.
Build a Custom CalculatorEnter the pixel count and the DPI. The formula is pixels divided by DPI, multiplied by 0.0254 metres per inch. For example, 1920 pixels at 96 DPI is 0.508 metres.
A 3000 pixel wide image printed at 300 DPI is 3000 / 300 = 10 inches wide, which is 10 x 0.0254 = 0.254 metres.
PPI describes pixels on a screen or in an image, while DPI describes printed dots. They are often used interchangeably for simple size calculations like this one.
Use the value your printer or designer specifies. 300 DPI is common for close-up print, and large formats viewed from a distance often use less.
