Quick reference

How percent to px works

Percentages are relative to the parent. This tool uses: pixels = (percent ÷ 100) × container width.

Set the container width to match your layout (e.g. 320 for a narrow column, 1200 for full width), then enter a percent to get the exact pixel value.

When this helps

  • Debugging responsive layouts when you need a fixed px value
  • Converting designs that use percent into px for implementation
  • Checking computed sizes without opening DevTools

Limitations

Result depends on the container width you enter. In the browser, the same percent in different containers gives different px. For root-relative units use the Percent to REM converter.
