Calibri vs Cambria: Office Sans vs Serif Compared
The Calibri vs Cambria pairing is the classic Microsoft Office decision: the warm humanist sans you type in by default versus the screen-ready serif that often headlines or footnotes it. Both were commissioned for Microsoft’s ClearType program and both ship free with Office and Windows, so the real question is whether your document calls for the openness of a sans or the structure of a serif.
What is Calibri?
Calibri was designed by Lucas de Groot and released by Microsoft in 2007, when it replaced Times New Roman as the default body font in Microsoft Office, a role it held until 2023. It is a humanist sans-serif distinguished by gently rounded corners and terminals, which give it a soft, warm, and approachable character. Its humanist proportions and subtle curves make it feel friendly rather than mechanical. As a ClearType system font bundled with Windows and Office, Calibri became one of the most widely seen typefaces in the world.
What is Cambria?
Cambria was designed by Jelle Bosma around 2004 and released by Microsoft as part of the ClearType font collection. It is a transitional, slab-influenced serif engineered specifically for comfortable on-screen reading. To stay sharp on displays, Cambria has sturdy strokes, a large x-height, even spacing, and robust serifs that hold up at small sizes and on lower-resolution screens. Bundled with Windows and Office, it became the natural serif companion to Calibri and a common choice for headings and printed documents that want a more traditional tone.
What’s the difference between Calibri and Cambria?
The headline difference is sans versus serif. Calibri is a soft humanist sans-serif; Cambria is a sturdy on-screen serif. Both were built for ClearType and both ship with Office, so they are designed to complement each other.

| Designer / year | Lucas de Groot, 2007 | Jelle Bosma, ~2004 |
| X-height | Large, modern | Large, screen-optimized |
| Contrast | Low, even strokes | Moderate, sturdy strokes |
| Best used for | Body text, email, modern documents | Headings, formal documents, print |
| Availability / license | System font, free with Office & Windows | System font, free with Office & Windows |
When should you use each?
Use Calibri when you want a clean, modern, approachable look for body text: everyday documents, email, presentations, and casual reports where its rounded warmth feels current and friendly. Use Cambria when you want a more traditional, authoritative feel, or when serifs aid the structure of long printed text: formal reports, academic-style documents, and headings that pair with a sans body. A common, effective approach is to use Cambria for headings and Calibri for body, mixing the two for clear hierarchy. For more on this fundamental choice, read our serif vs sans-serif guide.
Which is more readable / better for body text?
Both are highly readable because both were engineered for screens with large x-heights and careful hinting. For on-screen body text, many readers find Calibri’s open, even sans-serif forms slightly cleaner and more modern, while Cambria’s serifs can aid the eye across long printed lines. In short, Calibri tends to feel better for digital body copy and Cambria for printed long-form or where a traditional tone is wanted.

Are Calibri and Cambria free?
Both are free as system fonts bundled with Microsoft Windows and Office, so you can use either at no cost on any device where they are installed. As with other Microsoft ClearType fonts, embedding them as self-hosted webfonts or redistributing them requires the appropriate Microsoft license, since they are not open-source faces. For web projects you would typically declare them in a font stack and rely on installed copies, or substitute open alternatives.

Frequently Asked Questions
Is Calibri or Cambria the default Office font?
Calibri was the default body font in Microsoft Office from 2007 until 2023, replacing Times New Roman. Cambria was offered as a complementary serif, often the default for certain heading styles. In 2023 Microsoft began transitioning the default to a new typeface called Aptos, but Calibri remains widely used.
Can I pair Calibri and Cambria together?
Yes, and it is a classic pairing. Because Calibri is a sans-serif and Cambria a serif, they provide clear contrast while sharing a common Office heritage. A typical combination uses Cambria for headings and Calibri for body text, giving documents a clean, professional hierarchy without clashing.
Which font is better for a resume, Calibri or Cambria?
Both work well. Calibri gives a resume a modern, approachable, contemporary look, while Cambria lends a more traditional and formal tone. Choose Calibri for tech, design, or startup roles and Cambria for conservative fields like law or finance, though either reads cleanly and professionally.
Why do Calibri and Cambria look so clear on screen?
Both were commissioned by Microsoft for its ClearType subpixel rendering technology and designed with large x-heights, even spacing, and careful hinting to stay sharp on low-resolution displays. This screen-first engineering is why both render crisply at small sizes where older print-era fonts can look soft.
Is Cambria a serif or a slab serif?
Cambria is best described as a transitional serif with slab-influenced details. Its serifs are sturdier and more robust than those of delicate traditional serifs, which helps it survive on screen, but it is not a true slab serif. The slab influence gives it a solid, dependable appearance.
