Sentence Counter Formula
Sentences are split on ., !, or ? when followed by whitespace or the end of the text. Words per sentence = words ÷ sentences. Reading time uses 200 words per minute.
Sentence Counter Examples
Short caption
1–2 sentences, under 30 words.
Blog section
Aim for ~15–20 words per sentence for easier scanning.
Long draft
If words-per-sentence climbs above ~25, split long sentences.
Common Use Cases
- Checking average sentence length for readability
- Editing blog posts for shorter sentences
- Counting sentences in a paragraph or caption
