Typeface selection is a strategic decision, not a cosmetic one. Table of contents 1. [01The short answer](#the-short-answer) 2.

[07Our perspective](#our-perspective) ## The short answer On the web, almost everything is text – headlines, offers, buttons, prices. Typography is therefore not "one of the design elements" but its main carrier: it builds brand character, decides readability and directly affects conversion. Typeface selection is a strategic decision. ## A typeface speaks before you read Before the brain processes the content, the eye has already judged the form: serifs say "tradition, gravity, editorial"; geometric sans-serifs say "modernity, technology"; humanist faces say "approachability, warmth". This is not esoterica but learned cultural association – which a brand can harness or unknowingly undermine. A practical test: imagine a law firm set in Comic Sans, and an AI startup set in blackletter. Same content – completely different message. ## Readability is conversion A user who has to strain to read – doesn't read. The craft of readability comes down to a few measurable rules: - **Base size:** at least 16 px for body text; smaller sizes only for metadata. - **Line height:** 140–175% of the type size for paragraphs; tighter in headings. - **Line length:** 45–75 characters. A line spanning the full monitor width is a marathon for the eye – which is why good sites set text in width-limited columns. - **Contrast:** minimum 4.5:1 for text (the WCAG AA requirement). Fashionable light-grey text on white is designing against your own customers. - **Hierarchy:** readers scan – headings, subheads and emphasis must lead the eye through the page without instructions. ## Micro-typography – the details that add up Professional typesetting differs from defaults in details: real quotation marks, true dashes (– and —) instead of hyphens, non-breaking spaces where line breaks would hurt, correct numerals in tables. Each detail is small; together they produce the impression of quality that separates a premium brand from an average one. This site applies them automatically – a matter of implementation, not editorial labour. ## Performance: typography loads too Webfonts are files – and files cost milliseconds. Badly implemented typography hurts Core Web Vitals: text invisible until the font downloads, or a layout jolt at swap time (CLS). The hygiene rules: self-host the fonts, use WOFF2, prefer variable fonts to five separate weights, set `font-display: swap` and subset the character set to what you need. ## Licensing: you need the right to use the typeface A font for print, for the web and for an app are often three different licences. When selecting a brand typeface we check costs across all planned media – a licensing surprise at app launch can force a typographic rebrand. High-quality open-source faces (SIL OFL) are an increasingly serious alternative. ## Our perspective We have designed typography since the days when a typesetting error stayed in thousands of printed copies – that school of precision came with us into digital. We treat typeface selection as the foundation of identity: [this is how we build brands](https://sweetlava.eu/en/services/branding-design-systems/), from paper to design system. ## Related services - [ Brand identity design & design systems → ](https://sweetlava.eu/en/services/branding-design-systems/) - [ Publication design & DTP → ](https://sweetlava.eu/en/services/dtp-publishing/) ## Related articles Branding & typography · 14 April 2026 ## [ A company's visual identity step by step – from logo to design system ](https://sweetlava.eu/en/blog/visual-identity-step-by-step/) How a professional visual identity is made.

Usually 1–2 families are enough – one for headings and body (modern variable families carry the full range of styles) or a heading + body pair. Every additional family costs performance and risks visual chaos. What should I watch for when choosing a typeface for multilingual content? Completeness and quality of diacritics and extended character sets – in cheap or amateur typefaces accented characters can look bolted on. Test the typeface on real text in every language you publish, including italics and bold. ## A new brand identity ahead, or a clean-up of the current one?
