Discover the impact of font size and line height on website layout. Learn how to optimize these elements for better readability, user experience, and visual appeal.
Font size and line height are two critical elements of typography that significantly influence the readability, aesthetics, and overall user experience of a website. When used effectively, they can enhance the visual appeal of your content and guide users seamlessly through your site. In this article, we’ll explore the impact of font size and line height on website layout, along with practical tips to optimize these elements for better design and usability.
Why Font Size and Line Height Matter
- Readability: Proper font size and line height ensure that text is easy to read, reducing eye strain and improving comprehension.
- User Experience: Well-balanced typography creates a pleasant browsing experience, encouraging users to stay longer on your site.
- Visual Hierarchy: Font size and line height help establish a clear hierarchy, guiding users to the most important information.
- Aesthetics: These elements contribute to the overall look and feel of your website, making it visually appealing and professional.
Understanding Font Size
Font size refers to the height of the text, typically measured in pixels (px), points (pt), or ems (em). Choosing the right font size is crucial for readability and accessibility.
Best Practices for Font Size
- Body Text: Use a font size of 16px to 18px for body text. This range is comfortable for most readers and works well across devices.
- Headings: Use larger font sizes for headings to create contrast and hierarchy. For example:
- H1: 32px to 40px
- H2: 24px to 32px
- H3: 20px to 24px
- Mobile Devices: Increase font sizes slightly for mobile devices (e.g., 18px for body text) to account for smaller screens.
- Accessibility: Ensure your font size meets accessibility standards (e.g., WCAG guidelines recommend a minimum of 16px for body text).
Understanding Line Height
Line height, also known as leading, is the vertical space between lines of text. It is often expressed as a ratio (e.g., 1.5) or a percentage (e.g., 150%) of the font size. Proper line height prevents text from appearing cramped or too spaced out.
Best Practices for Line Height
- Body Text: Use a line height of 1.5 to 1.6 times the font size. For example, if your font size is 16px, a line height of 24px to 26px works well.
- Headings: Use a slightly smaller line height for headings (e.g., 1.2 to 1.4) to maintain a compact and cohesive look.
- Long Paragraphs: Increase line height for longer paragraphs to improve readability.
- Mobile Devices: Adjust line height for mobile screens to ensure text remains legible and well-spaced.
How Font Size and Line Height Impact Website Layout

- Proper font size and line height make text easier to read and scan, especially for users who skim content.

- Visual Hierarchy
- Larger font sizes for headings and smaller sizes for body text create a clear hierarchy, guiding users through your content.
- Consistent line height ensures a balanced and organized layout.

- Use relative units like ems or percentages to ensure scalability across devices.
