What Roblox says about Builder
On 7 March 2024, Roblox announced its own custom font family, Builder, on the Roblox Developer Forum. The family has three parts: Builder Sans, the main platform font made for readability at all sizes; Builder Extended, a bolder and more expressive variant; and Builder Mono, a monospaced version for coding in Roblox Studio. Roblox said the fonts would be used on the Roblox app, website and Creator Hub, and gave a more consistent brand as one reason for the change. The post does not name the designers.

Regular · Latin specimen
A screen-first sans with a tall x-height, close to Builder Sans in purpose and texture. It looks more neutral and has less personality in the bold weights.

Roblox's replacement for Arial, matching Arial's letter widths exactly. Pick it to match older Roblox games, not the current Builder look.
View fontThe logo is custom lettering
The Roblox wordmark is not typed in Builder or any retail font. In August 2022, Roblox CEO David Baszucki wrote that the updated logo uses new custom letterforms that are lighter and more modern. The second O went back to being a normal letter, so the tilted first O stands out more. The tilt itself was refined slightly but kept, because Roblox says it stands for building, progress and motion.
Evidence for this attribution ↓Can you use Builder outside Roblox?
Only in a narrow way. The Builder font licence lets anyone use the family free of charge to make and publish content on the Roblox platform, and to use it in digital promotions of that content off the platform. Any other use needs written permission from Roblox. That rules out using Builder for a school poster, a website or a brand that has nothing to do with Roblox. For those, use a free Google Font instead.
Evidence for this attribution ↓How to get the look
For Roblox-style interface text, pick a clean sans with a large x-height, set headings in a bold weight and body text in regular. Inter or Montserrat get close. When Roblox removed Gotham and Arial in 2024, it swapped them for Montserrat and Arimo, so those two will also match older Roblox games. For a logo-like effect, tilt one letter about 15 degrees rather than looking for a matching font.
Common questions
What font is the Roblox logo?
None. Roblox says its 2022 logo uses custom letterforms, so there is no font that types it. The tilted O is part of the drawing.
Is the Roblox font free?
Builder is free to use, but only for content you make for Roblox and for promoting that content online. Other uses need written permission from Roblox.
What happened to Gotham in Roblox?
Roblox removed Gotham and Arial in May 2024. Games that still used them were switched automatically to Montserrat and Arimo.
