VH to Pixels Converter (VH to PX)

Quickly convert CSS viewport height (vh) units to pixels (px) with this efficient tool. VH is a relative unit based on your screen's visible area, while PX is a fixed unit. Simplify your web design measurements with this handy VH to PX converter.

Steps to Use the Converter

• Enter the Viewport Height value.
• Input the View height value you want to convert.
• Press Enter or click the Convert button.

What is Viewport Height (vh)?

Viewport height (vh) is a CSS unit that represents a percentage of the visible screen space. It refers to the viewable area of a device’s screen, whether on a desktop, laptop, tablet, or smartphone.

• Understanding Viewport Height

  • On desktops and laptops, the viewport is the visible portion of the browser window.
  • On mobile devices, it refers to the screen area available for web content.
  • Every device has a specific viewport size, which manufacturers provide in their specifications.

How to Convert Viewport Height (vh) to Pixels (px)

Viewport height (vh) is a CSS unit that defines a percentage of the visible screen space. Unlike pixels (px), which are fixed units, vh adapts dynamically based on the device's screen size.

• VH to PX Conversion Formula:

  Use this simple formula to manually convert PX to VH:

  PX = (Viewport Height / 100) * VH

• Example Calculation

  Let’s say you’re working with a device viewport of 430px × 932px (iPhone 14 Pro Max). The viewport height is 932px.

  Now, converting 50vh to pixels:

  (932 ÷ 100) × 50 = 466px

  So, 50vh is equal to 466px on this specific device.

How to Get the Viewport Height (vh)?

You can easily retrieve the viewport height of a webpage using JavaScript. The window object provides an attribute called innerHeight, which returns the viewport height in pixels.

console.log(window.innerHeight); // Outputs the viewport height in pixels

This allows you to dynamically calculate and adjust elements based on the user's screen size.

Usage of Viewport Height (vh)

There are several practical use cases for vh in web design:

• Full-Screen Layouts (Sticky Header & Footer)

  To make the header stay at the top and the footer stick at the bottom, even on a blank page, use:

  body {
      height: calc(100vh - footerpx - headerpx);
  } 

  This ensures a responsive, full-screen layout.

• Checking if Content Fits within the Viewport

  If you need to determine whether an image or iframe will fit within 60vh, use JavaScript:

  const sixtyVhInPx = (window.innerHeight / 100) * 60;
  console.log(sixtyVhInPx); // Check if content exceeds this height
