Quickly convert PX to REM with our easy-to-use online tool.
Converting pixels (PX) to rems (REM) is a common task when working with responsive web design. By using relative units like REM, you can create more flexible, scalable layouts that adapt to different screen sizes. If you're tired of manually calculating these conversions, our PX to REM Converter tool is here to help.
PX (Pixel): A fixed unit of measurement that refers to a single dot on the screen. It is widely used in web design for pixel-perfect layouts, but it doesn’t scale well with different screen sizes and resolutions.
REM (Root Em): A relative unit of measurement based on the root element’s font size (typically the <html>
tag). One REM is equal to the font size of the root element, making REMs more flexible for responsive design.
To convert PX to REM, you can use this formula:
REM = PX ÷ Root font size
By default, most browsers set the root font size to 16px. This means that if the root font size is 16px, 1 REM will equal 16px. If the root font size is different, you'll need to adjust the calculation accordingly.
Our PX to REM Converter automatically handles the math for you. Simply input the pixel value (PX), and the tool will output the corresponding REM value based on the current root font size.
For example:
Here’s a conversion table to help you visualize how PX values convert to REM based on different root font sizes.
PX Value | Root Font Size 16px | Root Font Size 18px | Root Font Size 20px |
---|---|---|---|
8px | 0.5 REM | 0.44 REM | 0.4 REM |
16px | 1 REM | 0.89 REM | 0.8 REM |
32px | 2 REM | 1.78 REM | 1.6 REM |
48px | 3 REM | 2.67 REM | 2.4 REM |
64px | 4 REM | 3.56 REM | 3.2 REM |
128px | 8 REM | 7.11 REM | 6.4 REM |
Our tool is easy to use and free. Simply enter the PX value, adjust the root font size if necessary, and let the converter do the work. Whether you're designing for the web, creating accessible layouts, or ensuring consistency across devices, the PX to REM Converter simplifies the process.
