Frequently asked questions
What is the character limit for a tweet on X?
A standard X (Twitter) post allows 280 characters on a free account; X Premium raises it much higher. Note that X counts every link as 23 characters no matter its actual length, and some non-Latin characters count as two, so this tool's standard count can differ slightly from what X shows.
How long can an Instagram caption be?
Instagram captions allow up to 2,200 characters, and the same limit applies to comments. Bios are limited to 150 characters. Only the first roughly 125 characters show before the 'more' link, so front-load the important text.
Does this counter work for meta descriptions and SEO titles?
Yes. It includes the practical SEO limits — about 60 characters for a title tag and 160 for a meta description — alongside the social platforms, so you can write a snippet that won't get truncated in search results.
About this tool
The social media character counter checks your text live against the current character limits for every major platform at the same time: X (Twitter) posts and bios, Instagram captions and bios, Facebook, LinkedIn posts and headlines, TikTok, YouTube titles and descriptions, Threads, Bluesky, Pinterest, Reddit, plus SEO title tags, meta descriptions, Google Ads fields, and SMS segments. Each shows characters remaining and turns red when you go over, so you can size a post, caption, bio, or ad without switching between tools. Everything is counted locally in your browser and nothing you type is uploaded.
Like most tools on UtilityBase, the social media character counter runs entirely in your browser — nothing you enter is uploaded or stored on a server. It's free to use with no account required. Browse more text tools here.
