Bold Fonts: 20 Free Heavy Fonts for Headlines, Logos and Posters

Bold fonts are made to be noticed. They’re the fonts on movie posters, YouTube thumbnails, sports jerseys and sale signs. Here are 20 free bold fonts you can download today, plus the basics of how font weights work and how to make any text bold.

What makes a font bold?

Font thickness is called weight, and it’s usually measured on a scale from 100 to 900:

  • 100 – Thin
  • 300 – Light
  • 400 – Regular
  • 700 – Bold
  • 800 – ExtraBold
  • 900 – Black

Some fonts come in many weights, from Thin to Black. Others, often called display fonts, are heavy by design and only come in one style.

Real bold vs fake bold

If a font doesn’t have a bold version and you press the Bold button anyway, many apps create a “fake bold” by smearing the regular letters thicker. It often looks blurry and uneven. For crisp headlines, choose a font that has a real Bold, ExtraBold or Black style. You can see every style of a font in the type tester on its Originalfonts page.

How to make text bold

  • Word, Google Docs and most apps: select the text and press Ctrl + B (Windows) or Cmd + B (Mac).
  • WhatsApp: put asterisks around the text: *like this*.
  • Instagram bio or TikTok: there’s no bold button, but you can paste bold Unicode characters like 𝐭𝐡𝐢𝐬. See Copy and paste fonts.
  • Websites (CSS): use font-weight: 700 for bold, or 800 or 900 for heavier text, as long as the font includes those weights.

Tips for using bold fonts well

  • Keep it short. Bold fonts shine in headlines of a few words. Long paragraphs in heavy fonts are tiring to read.
  • Pair it with something calm. Use a bold headline font with a simple body font. Our Font Pairing page has ready-made combinations.
  • Give it room. Heavy letters need space around them. Try slightly wider letter spacing for all-capital headlines.
  • Check the license. All the fonts above can be used in commercial work, including logos.
