Source Sans Pro SemiBold font.

Source Sans Pro SemiBold is a clean sans-serif font with a stronger weight for headings, labels, buttons, and short blocks of text that need clear emphasis.

About Source Sans Pro SemiBold

Source Sans Pro SemiBold gives you a firm, readable sans-serif look without moving into an overly heavy display style. The 700 weight makes it useful when regular text feels too light, especially in interface labels, section titles, navigation, callouts, and compact headings. Because the style is straightforward, it can fit practical design work where clarity matters more than decoration.

The download includes TTF files for both upright and italic styles. Use the upright style for headings, UI text, and emphasis in layouts, then use the italic style sparingly for captions, notes, quoted text, or contrast within a typographic system. In the preview box, test it with your real words, not only sample alphabet text. Check short headings, all-caps labels, numbers, punctuation, and paragraph snippets so you can judge spacing and readability before using it in a project.

For interface-style layouts, test Source Sans Pro SemiBold with short labels, longer button text, and numbers. It is strong enough for hierarchy, but too much semi-bold text can flatten the page. Keep it for emphasis and let lighter text handle normal reading.

Usage Tips

Use SemiBold where you need hierarchy or emphasis, but avoid setting long paragraphs entirely in this weight unless the preview remains comfortable to read. Pair it with lighter weights from the same family when possible, or with a quiet serif or neutral sans-serif for contrast.
