Serif vs Sans-Serif on Screens: Which Is Actually Easier to Read in 2026

On today's high-resolution screens, neither is clearly easier to read. Studies comparing serif and sans-serif fonts generally find small or no differences in reading speed and comprehension. What makes a bigger difference is the specific font, its size, and the spacing around it.

First, the terms

Serifs are the small strokes at the ends of letters, as in Times New Roman or Georgia. "Sans" is French for "without", so sans-serif fonts such as Arial, Helvetica or Inter have none. When people say "sans" on its own, they usually mean sans-serif.

Why sans-serif used to win on screens

On older, low-resolution monitors, the fine details of serifs couldn't be drawn cleanly, so serif text looked fuzzy at small sizes. Sans-serif fonts held up better, and became the web's default. With modern high-density screens, serifs render sharply, so that advantage has mostly gone.

What actually makes text readable

• x-height: fonts with taller lowercase letters read better at small sizes.
• Clear letter shapes: easy-to-tell-apart I, l and 1, or rn and m.
• Size: at least 16 pixels for body text on the web.
• Line spacing: around 1.4 to 1.6 times the text size.
• Line length: roughly 50 to 75 characters per line.
• Contrast: dark grey or black on white or off-white.

Choosing for a website

• Sans-serif suits interfaces, buttons, small labels and most body text. Good choices include Inter, Source Sans, Open Sans and system fonts.
• Serif works well for long-form articles and adds a traditional or editorial feel. Georgia, Merriweather and Source Serif are designed for screens.
• Pairing a serif for headings with a sans-serif for body text, or the reverse, is common and fine.

Test with your real content at real sizes, on a phone and a laptop, before deciding.

For readers with dyslexia or low vision

Many readers with dyslexia prefer plain sans-serif fonts with generous spacing. See the best fonts for dyslexia and ADHD.
