Effortlessly convert between pixels (px) and relative units (rem). Streamline your responsive design workflow and boost your CSS coding efficiency with our intuitive converter.

PX to REM

This calculation is based on an adjustable default root font-size of px.

This free online px to rem converter swiftly transforms pixel (px) values into their rem equivalents. The rem (root em) unit, relative to the root HTML element's font size, provides superior scalability in CSS compared to pixels, enabling consistent UI design across devices.

Typically, 1rem equals 16px in most browsers. Our px to rem converter allows you to customize the root font size, tailoring your px to rem conversions to meet specific design requirements.

Modern web development widely adopts rem units for their flexibility in responsive design. Converting px to rem ensures consistent sizing across various screen sizes and user preferences, making your designs more adaptable.

FAQs about PX to REM

Have questions about converting px to rem? Check out some common queries about px to rem conversion below.

PX (pixel) is a fixed unit of measurement in digital design. It represents the smallest controllable element on a screen. In contrast, REM is a relative unit that scales with the root font size, making it useful for responsive design.

REM, which stands for 'Root EM', is a relative unit of measurement in CSS used for converting px to rem. It's based on the root element's font size, typically the <html> element. In the context of px to rem conversion, 1rem is equal to the font size of the root element, often set to 16px by default. This relationship between px and rem makes REM a powerful tool for creating scalable and responsive designs.

Our PX to REM converter automates the process of converting pixel values to rem units. It divides the pixel value by the root font size (default 16px). For example, 16px = 1rem, 32px = 2rem, etc. You can also adjust the base font size for custom conversions.

REM is preferred for responsive design as it scales with the root font size, making it easier to maintain consistent proportions across different screen sizes and user font size preferences. This flexibility is a key advantage of REM over PX in modern web development.

The default root font size in most browsers is 16px. This means 1rem is typically equivalent to 16px unless explicitly changed. Our PX to REM converter allows you to adjust this base size for custom conversions.

Absolutely! The PX to REM converter is an excellent tool for responsive design. Converting PX to REM helps maintain consistent proportions across different screen sizes and user font size preferences, which is crucial for creating flexible, responsive layouts.

Yes, our PX to REM converter is completely free to use. You can perform as many PX to REM or REM to PX conversions as you need without any cost.

Our PX to REM converter provides highly accurate results, typically showing up to four decimal places for precise conversions. This level of accuracy ensures your designs will be pixel-perfect across different devices and screen sizes.

Yes, you can easily copy the converted PX or REM values by clicking the copy button next to each input field, making it convenient to use the results directly in your CSS code.

To use REM units effectively, set a base font size on your root element (usually the <html> tag) and then use REM for font sizes, margins, paddings, and other properties throughout your CSS. This approach creates a scalable and maintainable design system.

Yes, our PX to REM converter can handle decimal values for both PX and REM inputs. This allows for precise conversions, even when dealing with fractional pixel or REM values in your designs.
