Your current viewport width: 1200px (1vw = 12px)
Complete Guide: PX to VW Converter
Everything you need to know about using this tool effectively
The PX to VW Converter transforms pixel measurements into viewport width (VW) units. 1 VW equals 1% of the viewport width. The formula is vw = (px / viewportWidth) × 100. For example, 144px on a 1440px viewport equals 10 VW. The tool lets you set the viewport width to match your target device. All processing happens in your browser.
VW is a CSS unit where 1 VW equals 1% of the browser viewport width. This tool divides the pixel value by the viewport width and multiplies by 100 to produce the VW equivalent. You configure the viewport width to match your design target.
Fluid typography
Convert pixel font sizes to VW units so text scales proportionally with the viewport width.
Responsive container widths
Calculate VW values for containers that should always occupy a fixed fraction of the screen.
Full-width layouts
Convert pixel-based column widths to VW for layouts that stretch across the entire viewport.
Scalable UI components
Set component dimensions in VW so buttons, cards, and inputs scale with screen size.
Enter pixel value
Type the pixel measurement you want to convert.
Set viewport width
Choose or enter the viewport width in pixels.
View the result
The VW equivalent is displayed instantly.
Copy the value
Copy the converted VW value for use in your CSS.
1 VW = 1% of the viewport width.
Use VW for typography that should scale fluidly with screen width (clamp() can set min/max bounds).
VW is unaffected by the parent container size, unlike percentages.
Combine VW with media queries for fine control at specific breakpoints.
What is VW in CSS?
VW stands for viewport width. 1 VW equals 1% of the width of the browser viewport. It is a relative unit that adapts to screen size.
Is my data sent to a server?
No. All conversion happens locally in your browser. Nothing is transmitted.
What viewport width should I use?
Use the width of your target device. Common values are 375px for iPhone, 768px for iPad, 1024px for laptop, and 1440px for desktop.
Can I convert VW back to pixels?
Yes. The tool supports bidirectional conversion. Enter the VW value and viewport width to get the pixel equivalent.
What is the difference between VW and percentage?
VW is always relative to the viewport width. Percentage is relative to the parent container width. VW ignores parent elements entirely.
