Letter Spacing

What is Letter Spacing in Web Design?

Letter spacing, also known as character spacing or tracking, is a fundamental concept in web design and typography. It refers to the adjustment of the horizontal white space between the characters in a text. This can be manipulated in CSS using the “letter-spacing” property.

Why is Letter Spacing Important?

Carefully considered letter spacing can significantly improve the legibility and aesthetic appeal of your website text. It impacts how a user interacts with the content, influencing their reading speed, text comprehension, and overall user experience. Too little spacing can make the text appear cramped and difficult to read, while too much can disconnect the characters, making the text seem disjointed.

How to Adjust Letter Spacing in CSS

In CSS, the ‘letter-spacing’ property is used to modify the space between characters. The value can be set in different units such as em, px, pt, or %.

Here’s an example:

Use with Caution

While it can be tempting to go overboard with letter spacing, it’s crucial to use it sparingly and appropriately. The goal is to enhance legibility and aesthetics, not to detract from them. Always test your design on multiple devices and screen sizes to ensure a consistent and user-friendly experience.

Letter Spacing and Accessibility

In terms of web accessibility, letter spacing plays a crucial role. The Web Content Accessibility Guidelines (WCAG) suggest a minimum letter spacing of 0.12 times the font size for optimal readability. Thus, while designing for accessibility, consider this guideline.


Understanding and effectively using letter spacing can make a significant difference in your web design. It’s not just about making your website look good, but also about improving user experience and accessibility.
