100 vw equals the full width of the viewport in pixels. So if your browser window width is 1920px, then 100 vw is exactly 1920 pixels.
Viewport Width (vw) units represent a percentage of the width of the browser window. Converting 100 vw to px means multiplying 1 by the current viewport width in pixels, giving you the exact pixel width of the visible area.

Conversion Formula
To convert vw to px, multiply the vw value by the viewport’s width in pixels and divide by 100.
Formula:
px = vw × (viewport width in px ÷ 100)
This works because 1 vw equals 1% of the viewport’s width, so 100 vw means 100% or the full width. For example, if the viewport width is 1366 px, then 100 vw = 100 × (1366 ÷ 100) = 1366 px.
Conversion Example
- Convert 50 vw to px (viewport width = 1440 px):
- Multiply 50 by 1440: 50 × 1440 = 72000
- Divide by 100: 72000 ÷ 100 = 720 px
- Result: 50 vw equals 720 px
- Convert 75 vw to px (viewport width = 1280 px):
- 75 × 1280 = 96000
- 96000 ÷ 100 = 960 px
- Therefore, 75 vw = 960 px
- Convert 120 vw to px (viewport width = 1920 px):
- 120 × 1920 = 230400
- 230400 ÷ 100 = 2304 px
- So, 120 vw equals 2304 px

Conversion Definitions
vw: A CSS unit representing 1% of the viewport’s width. The viewport is the visible area of a web page in the browser window. Using vw allows elements to scale relative to screen width, making designs responsive across devices.
px: A pixel (px) is a single dot on a digital display. It’s a fixed unit measuring size on screens, representing the smallest controllable element of an image or text. Pixels are used for precise control of layout and element dimensions.
Conversion FAQs
Why does 100 vw sometimes not match the full screen width?
Because 100 vw measures the viewport width excluding scrollbar, if the browser adds vertical scrollbars, the visible width shrinks but 100 vw stays the same. Also zoom settings or device pixel ratio can make pixel values seem different.
Can 100 vw be larger than the screen’s actual pixel width?
No, 100 vw equals 100% of the viewport width. It cannot be larger than the visible screen width. However, if elements have margins or padding, their total width might exceed viewport width causing overflow.
How does changing the browser window size affect vw to px conversion?
Since vw units depend on viewport width, resizing the browser changes the pixel value of vw. For example, 50 vw will be 960 px on a 1920 px wide window, but only 480 px on a 960 px wide window.
Are vw units supported on all browsers?
Most modern browsers support vw units, including Chrome, Firefox, Edge, and Safari. However, very old browsers might not support it fully, so fallback CSS or other units might be needed for compatibility.
What is the difference between vw and percentage (%) units?
vw is relative to the viewport width regardless of parent elements, while % is relative to the size of the parent container. Using vw ensures sizing based on window size, making it useful for responsive layouts.
