TL;DR: TikTok's official brand typeface is TikTok Sans, a bespoke font rolled out in 2023 (designed with Swiss foundry Grilli Type) to replace Proxima Nova. But "the TikTok font" means three different things: the brand font in the logo and UI, the preset text styles in the video editor (Classic, Typewriter, Handwriting, Neon and Serif), and the system font that renders your bio and captions.
Most people asking this are really asking one of three separate questions. Let's untangle them, because the answer changes depending on whether you mean TikTok's own typeface, the fonts you can pick inside the app, or the font your typed-out bio shows up in.
What is TikTok's official brand font?
TikTok's official brand typeface is TikTok Sans. It arrived in 2023, commissioned by parent company ByteDance and designed with the Swiss type foundry Grilli Type. Before that, TikTok used Proxima Nova, specifically Proxima Nova Semibold, a widely licensed geometric sans you'll recognize from thousands of other brands.
TikTok Sans is a clean, slightly rounded geometric sans-serif. It's built to stay readable on screen at small sizes and to handle the app's many languages. It's a variable font with weight, width, slant, and optical-size axes, and it covers 460+ languages across the Latin, Cyrillic, and Greek scripts. Then in July 2025 TikTok did something unusual: it expanded and open-sourced the family (with Type Network and Contrast Foundry), releasing it on Google Fonts under the SIL Open Font License. So unlike most proprietary brand fonts, you can legally download TikTok Sans and use it in your own projects.
This is the font in the wordmark, the buttons, and the menus. It's TikTok's visual identity. It is not automatically the font your captions or comments appear in.
What fonts can you use on captions inside the TikTok app?
Inside TikTok's video editor, tapping the Text (Aa) tool lets you type on-screen text and pick from a small set of preset styles. The long-standing ones are:
| Text style | Look | Best for |
|---|---|---|
| Classic | Clean, bold, highly legible sans | Default captions, anything you need read fast |
| Serif | Traditional serifs, Times-like feel | Formal, editorial, quote-style text |
| Neon | All-caps with a glowing outline | Party, music, high-energy clips |
| Typewriter | Monospaced with wide spacing | Storytelling, retro, dramatic reveals |
| Handwriting | Casual script | Personal, soft, emotional short phrases |
There are also controls for color, alignment and background highlight, plus the auto-captions TikTok can generate from your audio. TikTok adds and renames styles from time to time, so your app may show a slightly different list, and its help pages don't mention a bold or italic button. These are baked-in presets. You pick one; you can't install a new one, and you can't upload a custom font file into the app. For anything you actually want people to read at a glance, Classic is the safest pick.
What font does my TikTok bio and username appear in?
Your profile bio, display name, and comment text are not set in TikTok Sans or any of the caption styles. They render in your device's system font: SF Pro on iPhone/iPad (iOS) and Roboto on most Android phones. That's why the same bio can look subtly different from one phone to the next. The app is handing plain text to the operating system to draw.
Understand this before you try to "change" your bio font. TikTok gives you no in-app control over the typeface in these fields. If you want a stylized look there, you have to bring the styling into the text itself.
