VMAX to PX Converter
Conversion Guide
1. Identify the larger of viewport width or height in pixels. 2. Multiply the vmax value by 1% of the larger viewport dimension. Example: For a 800x600px viewport, 5vmax * (800 / 100) = 40px.

Frequently Asked Questions
Basics
What is VMAX?
The vmax unit is relative to 1% of the viewport's larger dimension (width or height). If width is larger than height, 1vmax equals 1vw, otherwise 1vmax equals 1vh.
What are good use cases for vmax?
Use vmax for elements that should scale based on the viewport's largest dimension, like overlays or backgrounds that need to cover the entire viewport regardless of orientation.
Is vmax supported in all browsers?
vmax is well-supported in modern browsers, but might need fallbacks for older browsers.
What is PX?
A CSS pixel (px) is a standardized unit of measurement that aims to make elements appear at similar physical sizes across different devices. Unlike physical screen pixels, CSS pixels are an abstraction that automatically scales based on device characteristics and user zoom settings.
Are CSS pixels the same as physical screen pixels?
No. On high-DPI (Retina) displays, one CSS pixel may actually use multiple physical screen pixels. For example, on a 2x display, 1 CSS pixel equals 4 physical pixels (2x2).
When should I use pixels vs relative units?
Use pixels for precise visual elements that should maintain their exact appearance, like borders (1px), box shadows, and small decorative details. For layout and typography, prefer relative units (rem, em, %) to ensure better accessibility and responsive design.
Do pixel-based layouts work well on mobile?
Fixed pixel layouts often break on mobile devices due to varying screen sizes. It's better to use relative units for layouts to ensure your design adapts smoothly across devices.
What happens to pixel values when users zoom?
CSS pixels scale proportionally when users zoom. If a user zooms to 200%, a 16px font becomes equivalent to 32px, ensuring content remains readable.
Do pixels affect accessibility?
Yes. Using fixed pixel values for text and layout can prevent proper scaling when users change their browser's font size settings. This creates accessibility issues for users who need larger text.
