FAQs
1. What is the most readable font for websites?
Sans-serif fonts like Open Sans, Roboto, and Helvetica are widely considered highly readable for screen-based interfaces due to their clean and simple letterforms.
2. How big should the body text be for good readability?
The ideal body text size is typically 16px–18px for desktop and 14px–16px for mobile, depending on your audience and content density.
3. What line height should I use for web typography?
A line height of 1.4 to 1.6 times the font size provides optimal spacing for readability and prevents text from appearing cramped.
4. Why is line length important in typography?
Line length affects reading speed and comprehension. Ideal length is 45–75 characters per line; too long or short can cause user fatigue or scanning issues.
5. How many fonts should I use in a single design?
To maintain visual harmony and focus, use no more than two or three complementary fonts—typically one for headings and one for body content.
6. Is justified text good for readability?
No, left-aligned (ragged-right) text is generally more readable on the web. Justified text can create uneven spacing that disrupts reading flow.
7. What is responsive typography?
Responsive typography automatically adjusts font sizes, spacing, and layout for different screen sizes to maintain readability on all devices.
8. How does color contrast affect typography?
High contrast between text and background improves readability, especially for users with visual impairments. Low contrast can make reading difficult.

WebAIM Contrast Checker, Google Fonts, Type Scale, and Adobe Fonts are excellent tools for evaluating and optimizing typography choices.
