Title Case Capitalizes Most Words, while Sentence case capitalizes only the first word and proper nouns. Both are common, but they carry different visual weight and different conventions depending on where you're publishing.

When Title Case fits better

Print magazines, traditional journalism, and formal marketing headlines still lean on Title Case because it reads as polished and intentional. It also visually separates a headline from surrounding body text at a glance.

When Sentence case fits better

Most modern blogs, SaaS products, and style guides (including Google's own documentation) have shifted to sentence case for a more conversational, human tone. It's also easier to keep consistent, since you don't need a rulebook for which small words to lowercase.

The safest approach

• Pick one style and apply it consistently across your entire site
• Match your competitors' convention if you're in a formal industry
• Use a case converter to instantly flip a headline between styles when you're testing which one looks better

If you're not sure which reads better for your brand, draft a handful of headlines and convert them between Title Case and Sentence case to compare side by side before you commit.
