Complete Guide: PX to VH Converter
Everything you need to know about using this tool effectively
The PX to VH Converter transforms pixel measurements into viewport height (VH) units. 1 VH equals 1% of the viewport height. The formula is vh = (px / viewportHeight) × 100. For example, 540px on a 1080px viewport equals 50 VH. The tool lets you set the viewport height to match your target device. All processing happens in your browser.
VH is a CSS unit where 1 VH equals 1% of the browser viewport height. This tool divides the pixel value by the viewport height and multiplies by 100 to produce the VH equivalent. You configure the viewport height to match your design target.
Full-height sections
Convert a pixel-based hero section height to VH units so it always fills the viewport on any screen.
Responsive vertical spacing
Calculate VH values for vertical margins and paddings that scale with the viewport height.
Mobile layout design
Convert pixel heights to VH for mobile layouts where the viewport is the primary container.
Scroll-snap layouts
Set section heights in VH units for scroll-snap interfaces that lock to full viewport sections.

1 VH = 1% of the viewport height.
On mobile browsers, the viewport height changes when the address bar shows or hides. Use dvh for dynamic viewport height.
100 VH does not always mean full screen on mobile due to browser chrome.
Use VH for elements that should scale proportionally to the screen height.
What is VH in CSS?
VH stands for viewport height. 1 VH equals 1% of the height 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 height should I use?
Use the height of your target device. Common values are 667px for iPhone 8, 812px for iPhone X, and 900px for a typical laptop.
Can I convert VH back to pixels?
Yes. The tool supports bidirectional conversion. Enter the VH value and viewport height to get the pixel equivalent.
What is the difference between VH and dvh?
VH uses the largest possible viewport height. dvh (dynamic viewport height) adapts when mobile browser UI like the address bar appears or disappears.
