📐 How to Use the PX to Viewport Units Converter
If you’re designing responsive layouts with CSS, using viewport width (vw) and viewport height (vh) is a smart way to ensure your elements scale perfectly on any screen size. This converter makes it effortless to switch from fixed pixels to fluid viewport-based units.
✅ Step-by-Step Instructions
- Enter the Pixel Value
Type the pixel size you want to convert — for example, the width of an element in pixels (e.g. 300px). - Enter the Viewport Width and Height
Specify the viewport dimensions in pixels. You can get these by checking the screen or browser size. For instance:
Viewport width: 1440px
Viewport height: 900px - Click “Convert to VW & VH”
The tool instantly calculates the equivalent vw and vh values using the formulas:
VW = (px ÷ viewport width) × 100
VH = (px ÷ viewport height) × 100 - Copy the Result
Click “Copy Result” to paste the output directly into your CSS or style sheet.
🧮 Example
If you enter:
Pixel value: 300px
Viewport width: 1200px
Viewport height: 800px
You’ll get:
300 ÷ 1200 × 100 = 25vw
300 ÷ 800 × 100 = 37.5vh
