Character Counter Online

Character limits exist for a reason — they force you to say more with less. But the consequences of going over (or well under) a limit aren't always obvious until your message is truncated in a search result, your ad gets rejected, or your tweet gets cut off mid-sentence.

For Google Ads, character limits are hard rules. A headline over 30 characters simply won't be accepted when you save the ad. A description over 90 characters gets flagged before publishing. Drafting outside the ad editor — in a doc or spreadsheet — without a live character counter means you're writing copy you'll have to cut down later, often at the cost of the best part of the message.

For social posts, the visible truncation point matters as much as the technical limit. Instagram shows roughly 125 characters before cutting to "more" — so the first sentence of your caption is the hook, and it needs to work within that constraint. LinkedIn's feed shows about 700 characters before the fold. If your key point is at character 800, most people never see it.

For SEO, meta descriptions truncate around 155–160 characters in desktop Google results. Writing a 250-character description isn't wrong, but the second half is invisible in the SERP — meaning your call to action and differentiating detail need to fit in the first 155. Pasting your description here before adding it to your CMS saves the back-and-forth of realising it's too long after the fact.
