What PPI Calculator (Pixels Per Inch) does
The PPI Calculator determines pixels per inch by accepting a screen's diagonal size, horizontal pixel count, and vertical pixel count. It outputs the PPI value, dot pitch, diagonal resolution in pixels, and total pixel count, providing a complete picture of display density. Users can input dimensions in inches or millimeters, and the tool automatically recalculates related metrics. Beyond the basic PPI figure, it includes explanations of pixel density, comparisons between PPI and DPI, and context for resolution categories, making it more than a simple calculator. The interface presents results clearly with shareable links and options to clear or reload the calculator for new inputs.

- Results depend on accurate input of diagonal size and pixel counts
- Assumes square pixels for calculations
- No unit switching between inches and millimeters during a single session
PPI Calculator (Pixels Per Inch) FAQ
- Can I calculate PPI if I only know the screen size and one pixel dimension?
- No, the calculator requires both horizontal and vertical pixel counts along with the diagonal size to compute pixels per inch accurately.
- Does the tool account for non-square pixels?
- The calculator assumes square pixels for its PPI and dot pitch calculations; results may not be accurate for displays using rectangular sub-pixel arrangements.
- What is the difference between PPI and DPI according to the tool?
- PPI measures pixel density per inch of a screen or image, while DPI typically refers to dots per inch in printing; the tool explains that PPI is the standard for screen resolution quality.
- How does the tool categorize screen resolution based on PPI?
- The calculator includes context on how different PPI values correspond to resolution categories, helping users understand whether a display qualifies as high, standard, or low density.
