Fonts with a perfectly round “O” have a clean, geometric look that feels modern, confident, and designed. That simple circular shape can make wordmarks feel more balanced, more minimal, and more “brand system ready,” especially for tech, design, wellness, and contemporary lifestyle projects.
In this list, you’ll find modern fonts where the “O” stays intentionally round (or close to perfectly circular), plus notes on when each font works best for logos, headlines, and brand typography.
1. Goji – Friendly Rounded Font With a Clean Round “O”

Goji is a rounded geometric typeface with a friendly tone and a clean circular structure in letters like O and o. It’s a great option when you want a modern, approachable look without going overly playful. Bonus: Goji also includes stylistic alternates, so you can push the personality further for logos and short display text.
2. Bauhaus Bau – Modular Geometric Font Built From Circles

Bauhaus Bau is a modular geometric font whose construction leans heavily on circular forms—so the “O” naturally reads as round, stable, and intentional. It’s ideal for logos, packaging, and bold headline treatments where you want a retro-modern Bauhaus vibe with a clean geometry underneath.
3. Scal – Futura-Inspired Minimal Geometric Sans With a Round “O”

Scal is a modern take on a classic geometric sans direction (think: clean and structured, with a contemporary edge). Its round shapes—especially the O—help branding feel precise and “designed,” while the sharper terminals on select letters add a bit of character so it doesn’t look generic.
4. Bauhaus Geo – Constructed Geometric Font With Alternate Letter Options

Bauhaus Geo is a constructed geometric font for a modular, modern look. The geometry keeps round letters like O feeling consistent and intentional, which is especially useful in wordmarks. Geo also includes alternate letters, so you can fine-tune the final logo lockup without switching fonts.

Auria Sans keeps things clean and minimal while adding personality through rounded ink traps that feel wavy and airy (without becoming decorative). It’s a strong choice for brands that want clarity and a sharply modern edge—especially in beauty, wellness, fashion, and jewelry.
6. Rail – High-Contrast Sans With a Crisp Round “O”

Bauhaus Rail is a modern high-contrast sans-serif with a thin connector line detail that makes the design feel engineered and distinctive. Round letters like O stay clean and geometric, which helps logos look intentional while still feeling fun and a bit quirky.
7. Bool – Playful Geometric Sans With Friendly Round Forms

8. Swav – Constructed Wavy Display Font With Rounded Letter Geometry

Swav is a constructed wavy font designed for logo and title use. Even though it has a futuristic movement, the underlying geometry stays clean—so round letters like O still read as intentionally shaped rather than messy. Best for brands that want modern energy with a controlled system.
