Sentence Length Analyzer
This analyzer measures the rhythm of your writing sentence by sentence. Paste any text and it reports four numbers — how many sentences, the average length in words, the shortest, and the longest — then lists every sentence longer than 30 words with its word count and a short preview so you can find it in your draft. Splitting follows end punctuation: periods, exclamation marks, and question marks. That works for most prose, but abbreviations like Dr. or e.g. can register as false sentence breaks and nudge the counts, so skim the flagged list rather than trusting the totals blindly. If nothing crosses 30 words, the report says so — a sign your pacing is already under control. The goal is variety, not uniform brevity: mostly compact sentences with an occasional long one is what makes prose feel effortless. Use the flagged previews to locate the sprawling sentences, split them, and run the analysis again to watch the average drop.

FAQ
how long is too long for a sentence
There is no hard limit, but sentences over 30 words often carry too much and lose the reader, which is the threshold this tool flags. The goal is variety — mostly shorter sentences with an occasional longer one for flow.
how does it split the text into sentences
It splits on periods, exclamation marks, and question marks, so standard punctuation drives the count. Abbreviations like "Dr." or "e.g." can fool the splitter and create a false break, slightly inflating the sentence count, so scan the results rather than treating them as exact.
what does the preview after a flagged sentence show
Each sentence over 30 words is listed with its word count and roughly the first 60 characters, cut at a word boundary. The preview exists so you can locate the sentence in your draft quickly — the fix itself, usually a split into two sentences, happens in your editor.
why does sentence variety matter
A run of long sentences feels breathless and dense, while all-short sentences read choppy. Varying length creates rhythm that keeps readers engaged, which is why seeing your shortest, longest, and average together is useful.
