A PX to REM converter is a tool that converts pixel (px) values to root em (rem) values. When working with CSS, this can be useful because it allows you to create responsive designs that adapt to different screen sizes and resolutions. It aids in determining your rem value, which is given by the pixel value.

What can you do with PX to REM Converter Tool?

Here are a few things you can do with a PX to REM converter tool:

  • The tool can convert pixel values to rem values, which you can then use in your CSS. When working with responsive designs, this can be useful because it allows you to create layouts that adapt to different screen sizes and resolutions.
  • You can scale elements proportionally to the font-size of the root element by using rem values. This allows the font and layout to be adaptable to user preferences, such as allowing larger font-size for accessibility purposes, and the layout to adapt accordingly.
  • You can make your website more accessible to users with different screen sizes and resolutions, as well as users with different font-size preferences, by using rem values.
  • If you're working on a larger project, you can easily maintain the proportions of the elements across the entire project by using rem values. It will be easier to update the font-size and everything will adjust accordingly, so you won't have to make changes in every single element that needs to be updated.
  • The free online PX to REM converter tool is compatible with Windows, MAC, Linux, Chrome, Firefox, Edge, and Safari

What is the difference Between PX and REM?

Px is a CSS unit that is relative to the font-size of the HTML root element. It is the smallest addressable element in a raster image . On the other hand, Rem is usually used in CSS development. The Rem unit lets you define a size relative to the HTML root element's font-size.

To understand the distinction between px (pixel) and rem (root ems), you must first understand what they are and how they behave. To begin with, they are measurements that are used on screen media or screens on various devices. In CSS, they are commonly used to measure lengths (Cascading Style Sheets).

The distinction is that px is a fixed-size unit. If you say this font is 16px, it is exactly 16px no matter where you put it. It's just that different devices may show it differently. A 16px font displayed on your computer monitor may appear differently on your mobile phone.

Root em (rem) units, on the other hand, are a type of relative measurement unit. They are determined by the font size of the web page's root element (typically the html> element). When an element's size is set to a specific number of rem units, it is proportional to the size of the text on the page. For example, if the root element's font-size is set to 16px, 1rem equals 16px. If you give an element a font-size of 2rem, it will be 32px. If you change the font-size of the root element to 20px, 1rem equals 20px, and an element with a font-size of 2rem equals 40px.

The use of rem units has the advantage of allowing you to create a consistent layout that adapts to the user's preferred text size, which can be beneficial for accessibility. If you need to be precise about the size of an element, PX units can be useful. In general, PX units are used in UI design, such as creating specific button and icon sizes, whereas REM units are used in typography because they allow size to adapt to the user's font preference.
