FontFYI

FontFYI is a font reference and pairing guide for developers and designers. It focuses on helping users explore Google Fonts and choose combinations for different projects, including resumes, blogs, landing pages, mobile apps, and code editors. The site describes itself as offering AI-powered pairing recommendations, side-by-side comparisons, and interactive typography tools.

Its font browsing area organizes typefaces by category, including Sans Serif, Serif, Display, Handwriting, and Monospace, and it highlights Popular, Trending, and New items. FontFYI also includes tools for font pairing, font preview with custom text and size, comparing two to four fonts side by side, generating type scales from ratios, building CSS font-family stacks with web-safe fallbacks, generating CSS @import and font-family code, checking text/background contrast, creating fluid CSS clamp() declarations, and converting between px, rem, em, and pt. An interactive variable font playground lets users explore axes such as weight and width.

The site also provides blog content on typography fundamentals, font selection, CSS typography, web performance, accessibility, design systems, type history and culture, and font reviews. Additional sections cover glossary terms, use cases, designers, languages, and an API, with developer documentation and OpenAPI references. The interface includes language options such as English, Korean, Japanese, Chinese (Simplified), Spanish, Portuguese, Hindi, Arabic, French, Russian, German, Turkish, Vietnamese, Indonesian, and Thai.
