When working on web design, one of those little tricks that makes everything smoother is knowing how to convert REM to PX. This conversion helps make your website layouts more responsive and flexible, scaling beautifully across different screen sizes. In this guide, I’ll walk you through the essentials of REM-to-PX conversions, complete with practical examples and a conversion table that you can keep handy!
If you’ve ever wondered why we even need REM and PX in the first place, you’re not alone. In simple terms, REM units scale things relative to a site’s base font size, which is a big win for responsive design. PX, however, gives you exact pixel control over an element. Being able to convert REM to PX lets you find that balance between flexibility and precision, perfect for modern web layouts.
REM stands for “Root EM,” and unlike EM units, which respond to an element’s parent, REM is based on the root document font size. It’s like saying, “No matter where I am in this layout, my size is based on the document’s main font.” In most browsers, 1 REM usually equals 16px—unless you’ve changed the base size, which you totally can.
PX is short for pixels, giving you a fixed, no-nonsense unit of measurement. PX doesn’t care about your root font; it just delivers exact pixel values. It’s great when you need control, but it’s not as adaptable for different devices.
Converting REM to PX is as easy as applying a simple formula:
PX=REM×Root Font Size (in PX)
If you’re using a root font size of 16px, then:
Easy, right? Let’s break it down with examples just to be sure.
If you’re using a custom root font, say 14px or 18px, your REM-to-PX conversions adjust accordingly. Here’s a quick table to help:
REM Value | 16px Base | 14px Base | 18px Base |
---|---|---|---|
0.5 REM | 8 PX | 7 PX | 9 PX |
1 REM | 16 PX | 14 PX | 18 PX |
1.5 REM | 24 PX | 21 PX | 27 PX |
2 REM | 32 PX | 28 PX | 36 PX |
This table can be your go-to guide if you’re working with a 16px root font size:
REM Value | PX Equivalent (16px Base) |
---|---|
0.25 REM | 4 PX |
0.5 REM | 8 PX |
1 REM | 16 PX |
1.5 REM | 24 PX |
2 REM | 32 PX |
Using REM and PX together can lead to a more flexible, visually consistent site. Here’s how that works:
html {
font-size: 16px; /* Root font size */
}
body {
font-size: 1rem; /* Equals 16px */
margin: 0.5rem; /* Equals 8px */
}
h1 {
font-size: 2rem; /* Equals 32px */
}
.icon {
width: 24px;
height: 24px;
}

Q: How does REM respond to changes in base font size?
If the root font size changes, all REM values adjust accordingly. So, if you set the base font to 18px, 1 REM becomes 18px automatically.
Q: Why use REM for some elements and PX for others?
REM keeps your layouts flexible, while PX helps maintain strict control. Try using REM for text sizes and PX for icons and fixed elements.
Q: Are REM and PX units interchangeable?
Absolutely—you can use both in the same file, choosing whichever unit works best for each element.
Knowing how to convert REM to PX can simplify your design process, making it easy to maintain consistent layouts that look good on any screen. With these tips, you’re all set to create web designs that are both scalable and stylish.
