Sentence Counter

Type or paste your text and the count updates live. A sentence ends at a period, exclamation mark, question mark, or ellipsis followed by a space or the end of the text, so abbreviations mid-sentence rarely split incorrectly. A block of text with no terminator still counts as one sentence.

The breakdown shows each sentence with its word count, so you can spot the overlong ones at a glance instead of hunting for them. Sentences over 25 words are flagged, a common readability guide, long sentences are where readers get lost.

No, it is a guide, not a rule. Plenty of great sentences run longer. But when many sentences pass 25 words, average readers start re-reading, so the flag is a nudge to check whether a long one could split in two.

For web writing, an average of 15-20 words per sentence reads comfortably. Academic writing runs longer, and marketing copy often shorter. The "Avg words / sentence" tile gives you that number live.

List items without ending punctuation are not split apart, so several bullets may count as one "sentence" until you add terminators. For strict line-by-line counting (like lyrics), our Syllable Counter's per-line view may fit better.

Yes, words, characters, paragraphs, and estimated reading time all show alongside the sentence count, so this doubles as a quick word counter.
