The best fonts for reading on screen

Short answer: pick a typeface designed for screen reading, at a comfortable size, with generous line height. Literata, Bookerly, Charter, Georgia and Source Serif all work. So does a good sans if you prefer one. Then stop adjusting and read.

Serif or sans on a screen?

The old rule was serif for print, sans for screens, because early displays couldn’t render fine serifs. That constraint is gone: modern phone screens have more pixel density than a laser printer had. Both work now.

Studies comparing serif and sans for on-screen reading speed and comprehension mostly find no meaningful difference. What they do find is that people read slightly faster in a typeface they see often, which suggests familiarity matters more than the shapes themselves.

The useful version: serif faces feel more booklike and help long-form reading feel less like screen use. Sans faces stay clearer at small sizes and on low-resolution or e-ink displays. Use the one you like.

What actually makes a typeface readable

• A large x-height. Tall lowercase letters relative to the capitals mean more visible letterform at the same nominal size. This is why some 16px fonts look small and others look right.
• Open apertures. The gaps in letters like c, e and s should stay open, so shapes don’t close up and blur together at small sizes.
• Distinguishable similar letters. Uppercase I, lowercase l and the digit 1 should not look identical. The same for O and 0, and for rn versus m.
• Moderate stroke contrast. Elegant faces with hairline thin strokes disappear at reading sizes on a backlit screen.
• A real italic. Books use italics constantly. A face whose italic is just slanted upright letters makes emphasis and titles read poorly.

Faces worth trying

Literata was designed for Google Play Books specifically for screen reading, and is a solid default: sturdy, large x-height, comfortable over hours. Bookerly was made for Kindle with the same brief. Charter and its open sibling Charis were designed to hold up at low resolution, which makes them excellent on e-ink. Georgia is decades old, on almost every device, and still one of the most legible screen serifs made. Source Serif and Merriweather are open faces built for text at screen sizes.

For sans, Atkinson Hyperlegible is worth knowing: designed by the Braille Institute to maximise character distinction for readers with low vision, and pleasant for everyone else. Inter, Source Sans and Open Sans are all safe.

OpenDyslexic, honestly

OpenDyslexic weights the bottom of each letter so shapes are harder to flip. Many readers prefer it, and preference is real. But controlled studies comparing dyslexia-specific fonts against ordinary sans faces at matched size and spacing have not found a speed or accuracy advantage; increased spacing did show one.

So the honest position: try it, keep it if it feels better, and don’t treat it as the intervention. The spacing settings do more. We go through the full setup in dyslexia-friendly reader settings.

The three settings that beat the font

1. Size. Most people read at least one step too small because the default was chosen for a screenshot, not for an evening.
2. Line height. Around 1.5 to 1.6 for body text. Tight leading is the single most common reason a page feels heavy.
3. Line length. Roughly 55 to 70 characters. On a phone in portrait that is nearly automatic; on a tablet held sideways it needs margins.

Get those right with a plain system font and the page will read better than a beautiful typeface crammed into a bad layout.

Two things people forget

The book has opinions. A well-made EPUB specifies fonts and styles for a reason. Overriding everything with one typeface flattens poetry, drop caps and small caps into uniform text. A good reader lets you choose while keeping the author’s structure, which is how Lectern handles it.

The screen matters as much as the face. The same font behaves differently on OLED, LCD and e-ink, and the right weight is not the same on all three. That trade-off is in reading on OLED vs e-ink.
