Capitalization on Social Media: Hashtags, Bios and Posts

Social media writing is informal, but capitalization still affects readability, accessibility and how your brand comes across.

Use CamelCase for hashtags

Hashtags cannot contain spaces, so multi-word hashtags can become hard to read: #socialmediatips. Capitalizing each word, as in #SocialMediaTips, makes them easy to scan and helps screen readers pronounce the separate words. Platforms treat hashtags as case-insensitive, so this does not split your reach.

Bios and profile names

• Use your brand's standard capitalization for your name.
• Sentence case usually reads best for the bio text.
• Avoid all-caps bios; they are harder to read on small screens.

Posts and captions

• Write in sentence case for a natural, conversational tone.
• Use capitals for a word or two of emphasis, if your brand voice allows it, rather than whole sentences.
• Remember that the first line of a caption is all many people see before "more", so make it clear and readable.

Fancy fonts and special characters

Some tools turn text into stylized Unicode characters such as bold script or bubble letters, and our reverse text generator can create upside-down and mirror text. These are fun, but screen readers often cannot read them, and search features on some platforms will not find them. Keep names, keywords and important information in normal text.

Keep a consistent style

Brands that post across several platforms benefit from a simple style sheet: headline case, hashtag style, how to write product names. A case converter makes it quick to adjust copy before posting.
