Word & Character Counter
Count words, characters, sentences, and reading time as you type.
Why word and character counts matter
Word and character counts are essential for a wide variety of writing contexts. Blog posts and articles often have target word counts for SEO — research suggests long-form content (1,500–2,500 words) tends to rank better for competitive keywords. Academic assignments and college essays typically have strict word limits that must be precisely met. Social media platforms enforce character limits: Twitter/X allows 280 characters, LinkedIn status updates allow up to 3,000 characters, and SMS messages are 160 characters per segment.
For developers, character counts matter when truncating display text, validating database column sizes (VARCHAR(255) is a common limit), generating slug URLs from titles, and working with APIs that have request body size limits. Sentence counts and reading time estimates help assess readability — the standard reading speed assumption is 200–250 words per minute for average adult readers.
Common mistakes
- Words vs tokens — Word counters typically split on whitespace and punctuation. This may differ from how ML models count "tokens" (which are sub-word units). Do not use this counter to estimate LLM token costs.
- Counting spaces vs not — Twitter historically counted all characters including spaces. Some systems count only non-whitespace characters. Know which definition your target platform uses.
