Font choices that make your content easier to read

The fonts that make content easiest to read are simple, well-spaced typefaces set at 16 pixels or larger, with about 1.5 times line spacing, lines that run 50 to 75 characters wide, and no more than two typefaces on the page. That combination matters more than which specific font you pick. A plain, well-spaced font beats a stylish, cramped one every time.

If you've ever landed on a website and clicked away within seconds without quite knowing why, bad font choices are often the reason. Your brain doesn't consciously register "this line spacing is too tight," it just feels like effort, and effort makes people leave. Let's go through what actually controls that feeling, and what to do about it.

Why size and spacing matter more than which font you choose

Most people worry about picking the "right" font first. That's backwards. Size and spacing do more of the work.

Here's what to aim for:

• Body text size: at least 16 pixels. Anything smaller forces people to lean in or zoom, especially on phones, and most of your visitors are on phones.
• Line height (the space between lines): around 1.5 times the font size. So a 16 pixel font should have roughly 24 pixels of space between lines. Too little and lines blur together; too much and paragraphs feel disconnected.
• Line length: 50 to 75 characters per line, including spaces. If you've ever read a paragraph that stretches the full width of a wide screen, you've felt why this matters, your eye has to travel too far to find the start of the next line.
• Paragraph spacing: a visible gap between paragraphs, not just a line break. It gives the eye a resting point.

You can have a beautiful font and still produce a page that's hard to read if these numbers are off. Fix these four things first, before you touch fonts at all.

How many fonts should a page actually use?

One or two. That's it.

Use one font for everything if you want to keep things simple, or use two: one for headings and one for body text. A common, reliable pairing is a slightly bolder or more distinctive font for headings, paired with a plain, highly readable font for the paragraphs underneath. The heading font can have a bit more personality since it's short text used sparingly. The body font needs to disappear into the background so people focus on what it says, not how it looks.

Three or more fonts on one page almost always looks like a ransom note, even to people who couldn't tell you why. It reads as unplanned rather than intentional, and it slows readers down because their eyes have to keep adjusting to new letterforms.

Serif or sans-serif: which is actually easier to read online?

For screens, sans-serif (fonts without the small decorative strokes at the ends of letters, like Arial or Helvetica) is generally the safer choice for body text, especially at smaller sizes on lower-resolution screens. Serif fonts (like Times New Roman or Georgia, with those small strokes) can work well for headings or for longer-form reading on larger screens, where the extra detail helps guide the eye along a line.

If you're not sure, default to a clean sans-serif for your body text. It's the safer bet across phones, tablets, and desktops, and it's what most readable websites use for exactly that reason.

The mistakes that quietly hurt readability

A few things sabotage font choices even when the font itself is fine:

• Low contrast: light gray text on a white background looks modern but is genuinely hard to read for a lot of people. Stick to dark text on light backgrounds, or light text on dark backgrounds, with enough contrast that you're not squinting.
• ALL CAPS for long stretches: fine for a short label or button, exhausting for a sentence or more. Our eyes read word shapes, and all-caps text erases those shapes.
• Justified text on the web: the kind where both edges of the paragraph line up straight. It creates uneven gaps between words that can make lines harder to scan. Left-aligned text with a ragged right edge reads more naturally on screens.
• Too many font weights: mixing thin, regular, bold, and extra-bold on one page creates visual noise. Pick one weight for body text and use bold sparingly, only to genuinely emphasize something.

None of these are hard rules that need special design training to fix. They're just habits worth checking on any page you're building or reviewing.

What to do next

If you already have a website, the fastest way to see how it's actually performing on readability and other basics is to run it through our free website grader, which scores an existing site and points out what's holding it back. If you're building something new, SimplePath builds a site for you by describing it in plain language, and handles font pairing, sizing, and spacing automatically as part of that, so you don't have to memorize any of the numbers above. You can see what SimplePath can build, from simple sites to full stores and blogs, on the products page, and if you have questions about how it works, our FAQ covers the common ones.
