What the metrics mean
A character counter measures every keystroke — letters, numbers, spaces, punctuation. A word counter tracks how many words your text contains. Both matter when something external sets the boundary: a 280-character post on X (formerly Twitter), a 60-character page title, a 500-word scholarship essay, or a prompt you need to keep inside a token budget.
Beyond the raw counts, SnapLetterCount shows reading time, speaking time, page estimates, sentence and paragraph structure, keyword usage, a readability score, and estimated AI tokens. These are editorial signals — they tell you how your text is built and where it will and will not fit, not how a search engine will rank it.
Use the sentence counter for rhythm and structure, the letter counter for alphabetic constraints, and the paragraph counter for organisation. For quick reference, see how many words fit on a page, how long 1,000 words takes to read, or how many words are in 500 characters.

Platform limits reference
The same numbers power the limit presets in the counter above, so they never drift apart.
| Platform | Limit | Type |
|---|---|---|
| X (formerly Twitter) post | 280 | Hard limit |
| SMS message | 160 | Hard limit160 characters per GSM-7 segment. Emoji or accented letters switch the message to UCS-2, which drops the segment to 70 characters, and longer texts are split into concatenated segments of 153 (or 67) characters. |
| Instagram caption | 2,200 | Hard limit |
| LinkedIn post | 3,000 | Hard limit |
| Facebook post | 63,206 | Hard limit |
| TikTok caption | 2,200 | Hard limit |
| YouTube video title | 100 | Hard limit |
| YouTube description | 5,000 | Hard limit |
| Discord message | 2,000 | Hard limit |
| Reddit post title | 300 | Hard limit |
| Page title tag | 60 | RecommendedSearch results truncate by pixel width, not character count. Around 60 characters is a practical guide, not a rule. |
| Meta description | 160 | RecommendedSnippets are rewritten and truncated by search engines. Treat this as an editorial target. |
| Google Ads headline | 30 | Hard limit |
| Email subject line | 50 | RecommendedMail clients cut subject lines at different widths. 50 characters keeps the whole line visible on most mobile inboxes. |
Hard limits are enforced by the platform. Recommended lengths are editorial guidance — you can go past them, but part of the text may be cut off in the interface. Check any of them against your text with the character counter.
Privacy and how we count
Everything runs in your browser. Your text is never uploaded, stored on a server, or shared — which makes the workspace safe for confidential documents, academic work, and unpublished drafts. Drafts you keep are saved locally on your own device only.
Characters count every code point you type, including spaces and punctuation; a separate figure excludes spaces. Words are whitespace-separated tokens. Sentences are split on terminal punctuation, with common abbreviations handled as exceptions. Reading time uses 238 words per minute and speaking time 130 words per minute, both adjustable assumptions rather than exact measurements. Page counts follow standard manuscript formatting. AI token figures on this page are estimates; the prompt workspace runs the real tokenizers for model-specific counts.
