10 vw equals 128 pixels on a screen that is 1280 pixels wide.
To convert viewport widths (vw) to pixels (px), you multiply the vw value by the viewport width in pixels, then divide by 100. Since 1 vw is 1% of the viewport width, 10 vw is 10% of the viewport width. For a 1280px wide screen, 10 vw equals 128 pixels.

Conversion Formula
The formula to convert vw to px is:
pixels = (vw value) × (viewport width in px) / 100
This because 1 vw equals 1% of the viewport width. So converting any vw value to pixels means finding the corresponding percentage of the viewport’s width in pixels.
Example: Suppose the viewport width is 1280px and you want to convert 10 vw to px:
- Multiply 10 by 1280: 10 × 1280 = 12800
- Divide the result by 100: 12800 ÷ 100 = 128 px
- Therefore, 10 vw equals 128 pixels on a 1280px wide screen
Conversion Example
- 5 vw to px (viewport width 1366px):
- Multiply 5 × 1366 = 6830
- Divide 6830 ÷ 100 = 68.3 px
- Result: 5 vw equals 68.3 pixels
- 20 vw to px (viewport width 1920px):
- 20 × 1920 = 38400
- 38400 ÷ 100 = 384 px
- So, 20 vw equals 384 pixels
- 7.5 vw to px (viewport width 1024px):
- 7.5 × 1024 = 7680
- 7680 ÷ 100 = 76.8 px
- Thus, 7.5 vw equals 76.8 pixels
- 12 vw to px (viewport width 1440px):
- 12 × 1440 = 17280
- 17280 ÷ 100 = 172.8 px
- Meaning 12 vw equals 172.8 pixels

Conversion Definitions
vw: A viewport width unit in CSS, representing 1% of the width of the viewport. The viewport is the visible area of a web page in a browser window. If the viewport width changes, 1 vw changes accordingly, making it useful for responsive layouts that adapt to different screen sizes.
px: A pixel unit used in digital displays representing a single dot on the screen. Pixels are the absolute measurement in screen rendering and do not change size based on viewport or screen dimensions. Pixels provide precise control over layout and element sizing in web design.
Conversion FAQs
Why does the pixel value of 10 vw change when I resize my browser?
The vw unit is relative to the viewport width, so when you resize the browser, the viewport width changes. Since 10 vw means 10% of the viewport width, its pixel value recalculates dynamically according to the new size, causing the pixel amount to increase or decrease.
Can I use a fixed pixel value instead of 10 vw for layout elements?
Using pixels fixes the element size regardless of screen size, which may cause layout issues on smaller or larger screens. 10 vw provides a flexible sizing that scales with viewport width, making designs more responsive. However, sometimes fixed pixels are preferred for precise control.
How do I access the viewport width value in JavaScript for conversions?
You can use window.innerWidth to get the current viewport width in pixels. This value updates dynamically when the window resizes, so you can use it inside event listeners or functions to calculate pixel values from vw units in real time.
Are vw units supported in all modern browsers?
Yes, vw units are widely supported in most modern browsers including Chrome, Firefox, Edge, and Safari. However, older browsers or some specific versions might have limited support, so testing is recommended if targeting legacy environments.
Is it possible for 10 vw to represent a larger pixel value than a fixed pixel width?
Yes, if the viewport is wide enough, 10 vw can be larger than a fixed pixel width. For example, on a 2000px wide screen, 10 vw equals 200px, which is bigger than a fixed 150px width. This flexibility allows responsive scaling but requires careful design choices.
