Font Pair Suggester

Contrast and harmony at the same time. The two fonts should not look identical (boring), but they should share an underlying mood. The classic recipe is a serif heading with a sans-serif body, or vice versa - the structural difference creates a visual hierarchy. Playfair Display headings paired with Lato body text is the canonical example: a high-contrast modern serif against a humanist sans, both with similar x-heights and a calm tonal feel.

Avoid pairing two fonts from the same family classification. Two serifs together (Merriweather and Lora) often look like a designer could not decide. Two geometric sans fonts (Montserrat and Poppins) blur into each other and lose hierarchy. The exception is a font superfamily designed to work together, like IBM Plex Sans with IBM Plex Serif - they share the same skeleton but display differently enough to create useful contrast.

The 20-font library covers the Google Fonts catalogue's most reliable workhorses. Playfair Display heading with Lato body works for editorial sites and luxury brands. Montserrat headings with Lora body suit blogs and SaaS marketing. Poppins headings with Crimson Text body lean modern with editorial warmth. Roboto with Roboto Slab is the safe corporate choice. Cormorant Garamond with Lato gives wedding and lifestyle vibes.

The suggester pulls three pre-vetted body font options for each heading font. These pairings come from the Google Fonts community recommendations and have been used in production by enough sites to be safe defaults. Click any suggestion to see it live in the preview. The CSS @import line is generated for you to copy directly into your stylesheet - it pulls only the weights you actually need (600 and 700 for headings, 400 and 500 for body) to keep page weight down.

Each Google Font you load adds 30 to 80KB to your initial page weight, and roughly 100 to 300ms of perceived load time on a slow connection. Two fonts is the practical upper limit for a fast site. Three is acceptable if one is only used in a small place (like a logo). Four or more starts to noticeably hurt Core Web Vitals scores.

Self-hosting the font files (download from Google Fonts and serve from your own domain) generally beats the @import approach now that browsers no longer share cached fonts across sites. Use font-display: swap in your @font-face declaration so text appears immediately in a fallback font and switches to the web font once it loads - this prevents invisible text during the load phase. Pair the typography choices with the [colour palette generator](/colour-palette-generator) and [colour contrast checker](/colour-contrast-checker-pro) to lock in a complete visual system.
