Typography on the web is fundamentally different from print design. On a screen, fonts battle against load times, browser variations, and the shifting constraints of responsive design. A truly effective web experience requires strict adherence to web design typography rules.
For modern, minimalist websites—a style that demands clean, airy aesthetics—these rules become even more critical. You must ensure that your elegant choice of typeface doesn’t compromise load speed or accessibility.
Here are 5 essential web design typography rules to master for creating professional, high-performing minimalist interfaces.
The first rule is technical: never use an unoptimized TTF or OTF file directly. Load speed is paramount to UX.
Modern websites must utilize WOFF2 (Web Open Font Format 2). This format offers superior compression, dramatically reducing font file size and ensuring your site loads instantaneously. Adhering to this rule improves both SEO performance and user retention.
Choose fonts, like Rusilla Minimalist Serif, that are designed with clean paths, resulting in smaller, more efficient WOFF2 files.
On the web, X-Height (the height of the lowercase ‘x’ compared to the capital letter) is the single most important factor for readability. Fonts with a high X-height are easier to read on a screen because the core body of the text is more visible.
Simultaneously, Line Height (Leading) must be generous for a minimalist look. Avoid tight spacing; a tight line height (e.g., 1.2x) that works in print will look compressed and exhausting on a screen. Instead, use a Line Height of 1.5x to 1.7x the font size (e.g., if the font is 16px, the ideal Line Height is 24px-27px). This ample, airy spacing is what defines minimalist readability.

Web design typography rules demand a well-defined type scale to establish visual hierarchy. Your H1, H2, and Body text should progress predictably (often using an established ratio like the Golden Ratio or a Major Second).
A modern minimalist site often uses one distinct display font for H1/H2 (to add character) and one highly readable Sans Serif for the Body text.
While designers often want to use smaller fonts for minimalism, 16px (the browser default) should be the absolute minimum font size for body text. This is an accessibility standard that ensures comfort for the average user and is a non-negotiable part of web design typography rules.
A reliable website must include a “font stack”—a prioritized list of fonts the browser can use if the main custom font fails to load.
Example Font Stack for a Custom Serif:
'Custom Font Name', Georgia, 'Times New Roman', serif;
This ensures that even if your beautiful custom font fails, the user still sees a readable serif font (Georgia or Times New Roman), upholding the integrity of the design hierarchy.
Adhering to these web design typography rules is critical for modern design. It shows your clients that you prioritize the technical stability and user experience of their brand, not just the visual appeal.
