Sizes, weights and spacing by role
These are computed values from the live page, which is what the Font Inspector panel shows when you click each element.
| Role | Font | Size | Weight | Line height | Letter spacing |
|---|---|---|---|---|---|
| Headline | Charlie Display | 48px | 500 | 1.25 | normal |
| Subheading | Charlie Display | 36px | 500 | 1.33 | normal |
| Body text | Charlie Text | 20px | 400 | 1.5 | normal |
| Navigation | Charlie Text | 16px | 400 | 1.5 | normal |
The main font stack in the CSS:
font-family: "Charlie Text", sans-serif;- Body text is a generous 20px with a line height of 1.5.
- The font files come from Contentful’s asset CDN, which suggests the marketing site is managed in Contentful.

}How we checked
We opened trello.com in Chrome on September 21, 2026 and read the computed styles of its visible text: the declared font stack, the font actually rendered, and how much of the page’s text each family sets. That is the same data the Font Inspector extension shows under Fonts on this page. We re-check these pages periodically, and the date above shows the last inspection.
