Social Media Character Counter

Write once, check every platform. Type your post and this shows the character count against the limits for X, LinkedIn, Instagram, Threads, TikTok and Facebook — so nothing gets cut off.

Need more than the free basics? Counting characters is the easy part; publishing across every account on schedule is the grind. A tool like Vista Social schedules and posts everywhere from one place.

Platform limits at a glance

X/Twitter caps at 280 characters, Threads at 500, Instagram and TikTok captions at 2,200, LinkedIn posts at 3,000, and Facebook at a huge 63,206. But the practical limit is shorter — most feeds truncate after the first line or two, so front-load your hook. Use this to stay within the hard limit, and write the opening line to earn the 'see more' click.

Frequently asked questions

What's the character limit on X / Twitter?

280 characters for a standard post. This tool shows your count against X and every other major platform at once.

Why does my post get cut off even under the limit?

Most feeds truncate after a line or two with a 'see more'. Stay under the hard limit, but put your hook in the first sentence to earn the expand.

Can I schedule posts to all platforms?

Not from this tool — it just counts. A social scheduler like Vista Social publishes and schedules across all your accounts.
