What you can do here

You supply the window

There is no measurement of this browser. The screen-resolution page reads that.

50 is half

The sample is the easy half of 800.

Not dvh or svh

Those mobile units differ when the browser chrome shows. This is classic vh.

The sequence

How to use the Vh to Px Calculator

  1. 1

    Type the design viewport

    800 is the sample. A phone might be 700 or 800 CSS pixels tall.

  2. 2

    Check 400

    Half of 800.

  3. 3

    Do not paste a percentage sign

    50 means 50 vh. The box is a number.

Worth knowing

  • Vh to Px Calculator on Toolspire: pixels = vh ÷ 100 × viewport height.
  • 50 vh of 800 px = 400 px.
  • 100 vh equals the viewport height you typed.
  • A viewport of 0 is rejected. A vh of 0 is 0 px.

A percent of a height you name

Classic vh is one hundredth of the viewport height. Fifty vh is half of whatever height you type. Half of 800 is 400. The page cannot see the window, so a wrong viewport is a wrong pixel count. Dynamic viewport units, which change when mobile browser bars hide, are not this unit. The screen-resolution tool can tell you the CSS pixel height of the window you have open.
