What is Open Sans Font?

Best Practices for Using Open Sans
Selecting Appropriate Weights
Use Light (300) for large display text where you want an elegant, airy appearance. Regular (400) is ideal for all body copy and general content. Semi Bold (600) works excellently for subheadings and navigation. Reserve Bold (700) and Extra Bold (800) for headlines, buttons, and elements requiring strong emphasis.
Optimal Typography Settings
For body text, maintain a font size of 16-18px with line height between 1.5-1.7 for comfortable reading. Ensure adequate letter spacing (0-0.02em) for optimal legibility. For headlines, sizes between 28px and 64px work well depending on hierarchy and context.
Perfect Font Pairings
Open Sans pairs well with various complementary fonts:
- Open Sans + Merriweather (humanist sans with friendly serif)
- Open Sans + Lora (clean sans with elegant serif)
- Open Sans + PT Serif (modern sans with traditional serif)
- Open Sans + Roboto Slab (humanist sans with geometric slab)
Color and Contrast
Ensure sufficient contrast between text and background. Target at least 4.5:1 contrast ratio for normal text and 3:1 for large text to meet WCAG accessibility standards. Lighter weights need higher contrast to maintain readability.
