Viewport units (VW and VH) allow elements to scale relative to the size of the user's screen. Our calculator makes it easy to take fixed pixel values from a design (like a 300px sidebar on a 1920px screen) and convert them into percentage-based relative units. This ensures your layout remains proportional across all monitor sizes.
