Frequently Asked Questions
What is PX to REM?
PX to REM is the process of converting fixed pixel (px) values into relative REM units based on a base font size. REM stands for "Root Em" and is used for accessible and responsive web design.
How to change the base font size?
You can adjust the "Base Font Size" field (default 16px) to match your project's CSS root configuration. The table and conversion will update instantly.
Why use REM instead of Pixels?
REM units allow elements to scale proportionally based on the user's browser font settings, improving accessibility and providing a consistent experience across different devices.
Is this useful for Tailwind CSS?
Absolutely! Tailwind uses a default 1rem = 16px scale. This tool helps you find the exact rem values for custom sizes not included in the default classes.
How to calculate REM?
To calculate REM, take the pixel value you want and divide it by the base font size (usually 16px). For example: 32px / 16px = 2rem.
Who should use this tool?
Web developers and UI designers use this tool to quickly calculate relative units for their CSS files to ensure their designs are responsive and user-friendly.
When to use REM?
It is recommended to use REM for font sizes, margins, and padding to allow your layout to breathe and adapt to individual user preferences.
