VW to PX Converter

VW to PX Converter — Viewport Width to Pixels

In CSS, 1vw = 1% of the viewport width. To convert vw to px, use
px = (vw ÷ 100) × viewport_width(px) —
choose your current width or a preset to get exact pixels.
This vw to px converter online is ideal for css vw to px sizing and
font size vw to px checks.

Convert VW to PX (and PX ↔ VW)

Use this fast vw to px calculator to turn CSS vw into exact pixels — or switch to px to vw (and optionally px to vh). Pick a viewport preset, enter a value, then copy/share the result URL.

Formula (VW → PX & PX → VW)

In CSS, viewport-relative width units (vw) are percentages of the viewport’s width. To get exact pixels
(css vw to px) or the reverse, use the following equations:

• VW → PX:
  px = (vw / 100) × viewport_width(px)
• PX → VW:
  vw = (px / viewport_width) × 100
• Viewport binding:
  vw is tied to the browser window’s width, so the pixel value updates when the viewport resizes
  (that’s why “how do you calculate px from vw?” depends on the current width).
• Font note:
  using vw for type creates fluid sizing; set sensible limits with
  clamp(min, preferred, max), e.g.
  font-size: clamp(16px, 1.2vw, 24px);
• Modern variants:
  svw, lvw, and dvw target safe/large/dynamic viewport widths on mobile and
  browser UI changes—handy when precise behavior is needed.

Font size (VW → PX)

Using vw for typography creates fluid text that scales with the viewport. To read it in pixels, apply
font size vw to px math: px = (vw ÷ 100) × viewport_width.

font-size: clamp(1rem, 1rem + 1.2vw, 2rem);

5. Need the reverse? Toggle to PX → VW and paste a pixel value to get VW.

// With a known viewport width (e.g., 1440)
const viewportWidth = 1440;

// VW → PX
const px = (vw / 100) * viewportWidth;

// PX → VW
const vw = (px / viewportWidth) * 100;

// Using the current window width
const pxNow = (vwValue / 100) * window.innerWidth;
const vwNow = (pxValue / window.innerWidth) * 100;

Conclusion

VW gives fluid sizing; to get pixels you need the current viewport width. Use a preset (375–1920) or your live width, and for typography pair VW with clamp() to keep text readable.
