100 Vh to Px – Easy Conversion Explained

100 vh equals the full height of the viewport in pixels. If your browser window height is 900px, then 100 vh equals 900 pixels.

The unit “vh” stands for viewport height, meaning 1 vh is 1% of the visible browser height. So converting 100 vh to pixels means calculating 100% of the current viewport height in pixels.

Conversion Formula

The formula to convert vh to px is:
px = vh * (viewport height in pixels) / 100

This works because 1 vh equals 1% of the viewport height. So, to get the pixel value for any vh unit, multiply the vh value by the total viewport height then divide by 100. The viewport height is the visible height of the browser window.

Example:
If viewport height = 900px and you want to convert 75 vh:
Step 1: Multiply 75 by 900 = 67500
Step 2: Divide by 100 = 675 px
So, 75 vh = 675 px.

Conversion Example

• Convert 50 vh to px with viewport height 800px:
  • 50 × 800 = 40000
  • 40000 ÷ 100 = 400 px
• Convert 120 vh to px with viewport height 950px:
  • 120 × 950 = 114000
  • 114000 ÷ 100 = 1140 px
• Convert 85 vh to px with viewport height 720px:
  • 85 × 720 = 61200
  • 61200 ÷ 100 = 612 px
• Convert 110 vh to px with viewport height 1000px:
  • 110 × 1000 = 110000
  • 110000 ÷ 100 = 1100 px

Conversion Chart

This chart shows values from 75.0 to 125.0 vh and their equivalent pixel values, assuming viewport height is 900px. To use the chart, find the vh value in the first column and see the corresponding px value in the second column. This helps you quickly see the pixel height without calculation.

Conversion Definitions

vh: The vh unit measures the viewport height, where 1 vh equals one percent of the visible height of the browser window. It dynamically changes as the viewport resizes, so elements sized in vh stay proportionate to screen height.

px: Pixels (px) are the fixed unit measuring individual points on a screen. They represent the smallest unit of digital display, defining dimensions in absolute terms, regardless of screen size or resolution variations.

Conversion FAQs

Does 100 vh always equal the full screen height in pixels?

Not always, because 100 vh measures the viewport excluding browser UI like address bars or toolbars, which sometimes reduce visible height. On mobile browsers, 100 vh can vary as UI elements appear or disappear, changing pixel equivalent.

What happens if the viewport height changes after page load?

The px value for vh units updates automatically with viewport resizing, but static calculations done beforehand won’t reflect new dimensions. Using JavaScript or CSS responsive units ensures sizing adjusts dynamically to viewport changes.

Are vh units affected by device pixel ratio?

Vh units relate to CSS pixels, which are logical pixels, not physical device pixels. Device pixel ratio scales physical pixels differently, but vh to px conversion uses CSS pixels, so ratio doesn’t directly affect vh values in pixels.

Can vh units be used for height on all elements?

Most elements support vh units for height or width, but some older browsers or specific contexts might not. Also, vh units can cause layout issues if viewport height is very small or when UI overlays reduce visible height unexpectedly.

Is 100 vh the same as 100% height?

No, 100% height depends on the parent element’s height, which may not be set or may vary. 100 vh always refers to the viewport height regardless of parent size, so it is more consistent for full viewport sizing.
