What Is a Character Counter?
A character counter counts every individual character in a piece of text — letters, numbers, punctuation, spaces, and special characters. It is distinct from a word counter, which groups characters into words. Character counters are essential wherever a platform enforces a hard character limit rather than a word limit.
WordCountNow's character counter displays both the total character count (with spaces) and the character count without spaces. Both figures are useful depending on what you're measuring against.
Why Character Limits Exist
Character limits serve different purposes depending on the context. Social media platforms impose limits because they were originally designed for short-form communication. Database fields have character limits to control storage costs. SEO guidelines recommend character ranges for titles and meta descriptions because search engines truncate text that exceeds a certain width in their results.
Understanding whether a limit refers to characters with or without spaces is important. Most social platforms count spaces as characters. Most SEO tools measure pixel width rather than character count, which is why a title full of wide letters like "W" and "M" may be truncated sooner than one using narrow letters like "i" and "l".
Character Limits You Need to Know
- Twitter/X: 280 characters per post
- Instagram caption: 2,200 characters (only first 125 shown before truncation)
- LinkedIn post: 3,000 characters
- Google title tag: 50–60 characters (approximately 600px wide)
- Meta description: 150–160 characters
- Google Ads headline: 30 characters per headline
- Google Ads description: 90 characters per description line
- SMS message: 160 characters (single SMS)
Characters With and Without Spaces
The distinction matters more than most people realise. "Hello world" is 11 characters with spaces and 10 without. For short copy like ad headlines, the difference is trivial. For longer content like LinkedIn posts or Instagram captions, spaces can add 15–20% to your character count.
When a platform says "3,000 characters", it almost always means with spaces. When a typographer talks about character count for line-length readability, they typically mean without spaces.
