next/font` is a reliable solution for using custom fonts in Next.js applications, eliminating complex workarounds and reducing code complexity. It automatically optimizes font loading with self-hosting, preloading only the characters needed, and preventing layout shift entirely by calculating the size-adjust property based on actual font files. With `next/font`, users can easily add new fonts and integrate them seamlessly into their site's design, enhancing typographical performance without the baggage associated with custom fonts.
