Character Counter with Platform Limits
Track your character count live against the limits of every major platform — X, Bluesky, Mastodon, Threads, Instagram, LinkedIn, YouTube, Reddit, Facebook, TikTok, Discord, Slack, SMS, and SEO meta tags. Pin the limits you care about, see remaining or over-budget characters at a glance, and write copy that fits the first time.

ツールの紹介
Track your character count live against the limits of every major platform — X, Bluesky, Mastodon, Threads, Instagram, LinkedIn, YouTube, Reddit, Facebook, TikTok, Discord, Slack, SMS, and SEO meta tags. Pin the limits you care about, see remaining or over-budget characters at a glance, and write copy that fits the first time.
ツール概要
Most character counters only show one number. This one shows the right number for the right place: 280 for an X post, 300 for Bluesky (graphemes, not chars), 160 for an SMS (bytes, not chars), 60 for an SEO meta title, and so on. Pinned platforms surface at the top with progress bars; the rest live in an expandable section. Counts include UTF-8 bytes (for SMS payloads), grapheme clusters (for emoji-aware platforms), characters, words, lines, and sentences.
ユースケース
- Draft a post that fits both X and Bluesky without rewriting
- Check that an SEO meta title won't be truncated in Google
- Confirm an SMS marketing message fits in one segment
- Make sure a LinkedIn headline doesn't exceed 220 characters
- Balance an Instagram caption against the 2,200 character cap
入力／出力の例
Same text, very different fit depending on the destination.

よくある質問
Why does the grapheme count differ from the character count?+
Emoji and some scripts use multiple Unicode code points to render a single visual character. Platforms like Bluesky count graphemes; this counter shows both so you don't get blindsided.
Why are SMS limits in bytes?+
SMS uses GSM-7 (160 bytes per segment) or UCS-2 (70 chars per segment) encoding. Special characters can push a message into a second segment, costing more. The byte count reflects the actual SMS payload.
Are these limits up to date?+
Limits track each platform's documented caps as of the tool's last update. Some platforms cap visible characters in the timeline differently from the actual post body — see the per-platform hints.
