Brand font guide
What font does Microsoft use?
Microsoft sets its logo and interface in Segoe UI, a sans-serif typeface by Microsoft / Monotype. Segoe UI is Microsoft's humanist system sans — relaxed, readable and the default voice of Windows.
Free stand-ins
Free Segoe UI alternatives
Segoe UI is a commercial typeface. These open-source Google Fonts capture its character and are free for personal and commercial use.
How we know it is Segoe UI
The identification comes from measuring real letterforms — relative x-height, stem weight, stroke contrast and letter width — the same four metrics the font finder uses on any screenshot you upload. Segoe UI has a signature silhouette, and the free fonts listed above were matched against it on those same numbers.
Recreate the Microsoft look for free
You can set your own site in any of the free alternatives above and get remarkably close to the Microsoft feel — same weight, similar x-height and spacing — without paying for a commercial licence. Each card links to a detail page with the ready-to-paste CSS embed.
