Font pairing guide

Free font pairing tool for sharper product typography. Good typography is rarely one font in isolation. Headlines need character at 32–48px, body copy needs endurance at 14–18px, and product screens need numbers, buttons, and bilingual labels to feel balanced together.

These samples load real font files and render the same copy, sizes, and weights you would ship. Compare rhythm on screen, not thumbnails.

UI card Inter · 18px title

When Latin and Hangul share one card, preview both scripts at production sizes.

Pairing checks that matter

Run these checks at the sizes you will actually ship.

Headline personality vs. body stability: do they support each other instead of competing at 24px vs. 16px?
Latin and Hangul together: baseline rhythm, width, and weight steps still feel natural in one sentence.
Cross-medium use: does the pair survive slides, landing pages, and dense 12–14px UI screens?
Numeric emphasis: do prices, percentages, and table figures stay aligned when weights shift to 600 or 700?
Fallback behavior: if one font lacks a weight, does the substitute break button hierarchy or chart labels?

Curated starting pairs

SaaS UI: Inter 14px body (400) + Satoshi 20px section titles (600); swap Inter for Geist on developer tools.
Editorial landing: Fraunces or Lora headline at 40px with Source Sans 3 body at 18px for long reads.
Korean product screens: Pretendard 14px UI copy (400/500) + Clash Display or Paperlogy 32px campaign titles.
Investor decks: DM Sans or IBM Plex Sans body at 18px with a sharper Sora or Outfit headline at 44px.
Developer docs: JetBrains Mono 13px code snippets with Inter 15px prose and 600-weight H2 headings.

Common pairing jobs

Editorial and reports: serif headline with a calm sans body; keep line length under 70 characters at 16–18px.
SaaS UI: neutral sans for interface copy with a sharper display accent reserved for marketing hero blocks.
Korean product screens: Hangul-first body fonts (Pretendard, SUIT, Noto Sans KR) with a compatible Latin companion.
Brand campaigns: expressive display for billboards and social crops; restrained sans for product UI and forms.
Slide systems: one display family for cover slides and a separate workhorse sans for data-heavy inside pages.

Pairing mistakes to avoid

Matching two decorative fonts that fight for attention in the same 1080p above-the-fold layout.
Using a thin display weight for 12px helper text because it looked fine at 48px in the hero mockup.
Pairing a Latin-first headline with a Hangul body whose x-height and stroke width feel mismatched.
Assuming Google Fonts pairing suggestions replace testing with your real navigation labels and error strings.
Finalizing pairs before checking whether both families allow web embedding, app bundling, and PDF export.

How to pair fonts in snapdeck font

Open Pairs and paste a real headline plus two sentences of body copy from your product or deck.
Set headline preview to 32–48px and body to 14–18px depending on UI vs. slide context.
Try three directions: neutral/neutral, display/neutral, and serif/sans before opening Similar on either side.
Toggle weights 400, 500, 600, and 700 to confirm buttons, captions, and chart labels still align.
Save finalists only after opening each font’s official license page for your delivery channel.
