The best place to get free sans serif fonts is Google Fonts, which lists 723 sans serif families, all flagged open source, including Roboto, Open Sans, Inter, Montserrat, Lato and Poppins. DaFont has 4,407 sans serif fonts, but only 827 pass its completely free or open licence filter, and popular picks such as Coolvetica and Akira Expanded are personal use only.
Sans serif fonts are the workhorses: clean letters without the little feet, used for websites, apps, logos, menus, slides and most of what you read on a screen. Because they're so plain, choosing one feels low stakes. It isn't. The font you pick ends up on every page, invoice and post, so it's worth picking one with a licence you never have to think about again.
Google Fonts: 723 sans serif families
Google's own font list holds 1,951 families, and 723 of them sit in the Sans Serif category. Every family in the list is flagged open source. These are the most used, based on Google's popularity ranking:
| Font | Styles | Variable | Character |
|---|---|---|---|
| Roboto | 18 | Yes | Neutral, very readable on screens |
| Open Sans | 12 | Yes | Friendly and open, great for body text |
| Inter | 18 | Yes | Clean and clear at small sizes |
| Montserrat | 18 | Yes | Geometric, strong for headings |
| Lato | 10 | No | Warm, slightly rounded |
| Poppins | 18 | No | Geometric, popular for modern brands |
| DM Sans | 20 | Yes | Low contrast, tidy at small sizes |
One newer arrival: Google Sans, Google's own typeface, was added to the library in December 2025 and is flagged open source in the list. It already ranks among the most used families.
What a variable font changes for you
Of the 723 sans serif families on Google Fonts, 293 are variable fonts. Instead of a separate file for every weight, one file holds the whole range, so you can pick any weight between thin and black. For a website, that usually means fewer files to load. For a brand, it means one family can cover a heavy headline, a medium subheading and light body text.
Inter, Roboto, Montserrat, Open Sans, Raleway, Nunito, Manrope and Figtree are all variable. Lato and Poppins aren't, though both come in plenty of fixed weights.
Free sans serifs made for easier reading
Some sans serif families on Google Fonts were designed with readers who struggle in mind. Atkinson Hyperlegible comes from the Braille Institute, working with Applied Design Works, and it's on Google Fonts in four styles. Lexend, by Bonnie Shaver-Troup and Thomas Jockin, is a variable family with nine styles. Both are open source, and both are worth testing if your audience includes older readers or people reading on small phone screens.
DaFont sans serifs: check the label
DaFont's Basic, then Sans serif category listed 4,407 fonts. Filter for completely free plus Public domain, GPL or OFL and 827 remain. The most popular fonts there show why the filter matters:
- Coolvetica, Akira Expanded, Cocogoose, Nexa and Heavitas are marked free for personal use.
- Lemon Milk is donationware, so check the designer's terms before business use.
- Bebas Neue is listed as Public domain, GPL or OFL, and it's also on Google Fonts.
- Roboto and Alte Haas Grotesk are labelled completely free.
If a personal-use sans serif is the exact look your brand needs, contact the designer about a commercial licence. Otherwise, there's almost always an open source alternative on Google Fonts with a similar shape. Bebas Neue is the easy example: it shows up on both sites, and the Google Fonts version comes with the open licence spelled out, so you don't have to dig through a readme to know where you stand.

A sans serif you may already have
If you pay for Microsoft 365, Aptos is in Microsoft's cloud fonts list, in regular, display and bold weights. Microsoft says cloud fonts download on demand in the latest Office apps, as long as your device is online and optional connected experiences are turned on. It's handy for documents, but it isn't something you can install on your website the way you can with Google Fonts.

Choosing and installing a free sans serif
- Decide where it'll live most: screens, print or both. Inter and Roboto suit screens, Montserrat and Poppins suit bold branding.
- Pick one family with at least four weights, so you never need a second sans serif.
- Download it and keep the OFL licence file with the fonts.
- Install it on your computer, or connect it to your website through your theme or a font plugin.
- Test your real headings and a full paragraph at the size your reader will see.

My pick
For most small businesses, I'd pick Inter or Open Sans for body text and Montserrat or Poppins for headings, all from Google Fonts. They're open source, so the OFL FAQ allows them in logos, signage, business cards and print without extra permission. If you only want one family for everything, choose a variable font such as Inter or Roboto and use weight, not a second typeface, to create contrast.
