11 Font Pairing Tools For Better Legibility [Updated]


When it comes to online content, we want to make sure it is valuable, based on facts and helpful. But one important “detail” is sometimes neglected and it is legibility. Do designers check if websites are comfortable to read? Do they consider font pairings?

Legibility is crucial, especially for websites which are focused on providing lengthy content such as magazines and blogs. But not only these should put effort in the legibility check and optimization.

One of the most significant things to consider when designing web apps and websites is what fonts to use.
Should you stick to Arial or Helvetica? What about the modern ones such as Open Sans and Roboto? Serifs or Sans Serifs? Or combination of both?

If you have some spare time, you may head off to FontReach – an online tool ranking the web according to font – and check what are the most popular fonts used on websites today. Surprisingly or not, Arial is the font used the most – 604, 158 sites. The second place is for Helvetica Neue, used on 281,150 websites and Verdana is on the third place with 258,968 websites.

You can check all the top fonts here.

Using the statistics, we can draw the conclusion that web designers and developers prefer Sans-Serif fonts. Why is that? Arial is one of the oldest fonts used on the web and somehow a default one, if you are not using any particular framework. Bootstrap, on the other hand, have Helvetica Neue as a default font in their main css file. This might be the answer for the popularity of the top two typefaces.

Moreover, serifs are usually considered as more decorative fonts but it does not automatically mean that they are less legible.

Contrastingly, Sans Serifs are perceived as the ultimate choice for websites as they provide better legibility. Again, this does not automatically mean readable.

Sans Serifs and Serifs Combined

In the last couple of years, many websites combine Sans Serifs with Serifs which proves to be an eye pleasing combination. Let’s take Smashing Magazine as an example for this trend. The main titles are presented by using Skolar Bold which is a robust serif, while the main text is laid out with Proxima Nova.

Smashing Magazine Font Pairing

The H2 is defined by Skolar Bold (Serif), the intro text is also with Skolar Bold and for the main article text they use Proxima Nova (Sans Serif).

In terms of legibility, there is no doubt that the titles, subtitles and the copy are easy to read which results in better comprehension of the written content.

A vital role in legibility is also considered the content styling. What is the appropriate line-height for both titles and copy? What about the font sizes? Can letter spacing help?

It used to be a bit easier before the responsive design and all these devices, as people read content only on desktops. Now, not so much. Different device sizes should be considered when designing a responsive size. A Sans Serif typeface can be legible enough on desktop but on smartphone to be a complete disaster. Serifs also can look really good on desktops and totally failing on a mobile phone.
