About the Character Counter

The ByteTools Character Counter shows a live character count — with and without spaces — plus word and line counts as you type. Built-in limit meters for Twitter/X (280), Instagram captions (2,200), SEO meta descriptions (160) and SMS (160) show exactly how many characters you have left on each platform.

It is made for social media managers, copywriters and SEO specialists who need to stay inside strict length limits. Each meter fills as you type and turns red with a clear over-limit warning the moment you exceed a platform's maximum.

All counting happens locally in your browser. Your text is never uploaded or stored, so drafts, ad copy and private messages stay completely private.

Frequently asked questions

How many characters can a tweet (X post) have?

A standard post on X (formerly Twitter) allows 280 characters. URLs are counted as 23 characters regardless of length, and most emoji count as 2. The counter's Twitter/X meter tracks the 280-character limit as you type.

How long can an Instagram caption be?

Instagram captions can contain up to 2,200 characters, though only the first 125 or so are visible before the 'more' cut-off. Keeping your hook in the first line matters more than using the full limit.

How many characters should a meta description be?

Google typically displays around 155–160 characters of a meta description before truncating it. Aim for 120–160 characters so your full message shows in search results without being cut off mid-sentence.

Do spaces count as characters?

Yes — on social networks, in SMS messages and in meta descriptions, spaces count toward the limit. That is why this tool shows both values: use the 'with spaces' count for platform limits and the 'without spaces' count for typing or translation estimates.

How many characters is one SMS message?

A single SMS holds 160 characters using the standard GSM alphabet. If you include emoji or special Unicode characters, the limit drops to 70 per message and longer texts are split into multiple segments.
