Have you ever landed on a website and immediately had to squint to read the text? This is frustrating, and it’s a big problem for your website. A font Size that’s too small or too hard to read can hurt your site’s performance, user experience, and even your search rankings.
Here’s a simple truth: if a website is a pain to read, visitors will leave. When they leave quickly, it raises your bounce rate and signals to Google that your page isn’t useful. But a well-designed page with clear, readable text keeps visitors on your site longer, which helps your SEO.
Finding the Right Font Size for Your Audience
Understanding Font Measurement Units
The internet is different from a printed page, and so are the units we use for fonts. While you might be familiar with points (pt) or pixels (px), many modern websites use relative units like rem and em. These relative units are the preferred method for responsive web design because they automatically adjust to fit different screen sizes, from a desktop monitor to a smartphone.
Google’s Recommended Font Size
When choosing a font size, a good place to start is with Google’s recommendation. The Google Lighthouse tool, which measures a site’s mobile friendliness, recommends a minimum base font size of 16px. This means your main body text should be at least 16 pixels to ensure it can be read comfortably on all devices.
Optimizing Your Content Beyond Just Font Size
A great font size is only one piece of the puzzle. The overall readability of your content is also determined by other elements. These include the space between lines, the spacing between paragraphs, and the space between headings and the text below them. All of these elements work together to create a smooth reading experience.
Improving Content Quality
Beyond technical details, the quality of your writing matters too. For content that’s easy to read and grammatically correct, you can use a free tool like our Grammar Checker or AI Paragraph Rewriter to instantly improve your text and make it more professional.
How Font Size Affects Page Structure for Search Engines
Google doesn’t just look at the size of your text for readability. It also uses text size to understand the structure of your page. A larger font will be considered more relevant than a smaller font, regardless of whether it’s an H1 or H2 heading. This makes sense when you think about how we, as humans, scan a page. We naturally use large headings and subheadings to understand the hierarchy of information. Google does the same.
In the end, choosing the right font size and styling your content with a clear visual hierarchy helps both search engines and your users.
Conclusion
Font size itself is not a ranking factor, but choosing the right size is an essential part of creating a positive user experience. This, in turn, helps improve your SEO performance and conversions.
