What this tool does

Count sentences, words, characters and paragraphs in any text, with average sentence length and estimated reading and speaking time. Abbreviations such as 'Dr.' or 'U.S.A.' contain periods and will inflate the sentence count — the counter follows punctuation, not grammar. Decimal numbers like 3.5 do not split sentences because the split requires the punctuation to end a segment with following content.

How to use the Sentence Counter

  1. Enter or select text.
  2. Read the calculated result; change any measurement to compare alternatives.

Formula

Sentences are split on terminal punctuation (. ! ?) — a trailing fragment without punctuation still counts as one sentence. Words are whitespace-separated tokens containing a letter or digit. Reading time assumes 200 words per minute and speaking time 130 words per minute, the standard average rates.

Frequently asked questions

It splits the text at full stops, exclamation marks and question marks, and counts every segment that contains at least one word. A final sentence with no ending punctuation is still counted.

Usually abbreviations and initials: 'Dr. Smith arrived. He stayed.' contains extra periods inside 'Dr.', which a punctuation-based counter reads as sentence ends. Spelling abbreviations out gives the exact count.

Plain-English guidance targets roughly 15–20 words per sentence. Averages above 25 words usually feel dense; very short averages (under 10) can feel choppy in long-form writing but work well for instructions and web copy.

Reading time divides the word count by 200 words per minute (average silent adult reading) and speaking time by 130 wpm (average presentation pace). The Speaking Time Calculator tool lets you adjust the pace precisely.
