What is Longest Word Finder?
The Longest Word Finder reports the longest word in a passage, its length, and the average word length across the text. Paste an article, a subtitle file, or a puzzle entry and the tool returns the winning word alongside the word total it was measured against. Digits and standalone punctuation are skipped, so a date or a symbol does not win by accident. A hyphenated compound stays one word, and the first of two equally long words is reported.
How does Longest Word Finder work?
The tool matches sequences that begin with a letter and continue through letters, apostrophes, and hyphens, so don't and state-of-the-art are each read as one word. Anything that starts with a digit is skipped, which keeps version numbers and prices out of the comparison.
Each match is measured with the string length property, so internal apostrophes and hyphens count toward the length. The loop keeps the first word that beats the current record, which means ties resolve to the earliest occurrence. Average length is the total length of every matched word divided by the number of words.

Analysing subtitle files
Find the longest word in a caption track to judge how quickly a line will need to be read.

Pro Tips
- 1
A hyphenated compound counts as one word, so state-of-the-art reports a length of 16.
- 2
When two words share the same length, the one that appears first in the text is reported.
- 3
Paste a word list with one entry per line to find the longest option in a naming or domain shortlist.
- 4
Digits are ignored, so a product code such as XR-500 contributes its letters only.
- 5
Compare the longest word with the average length to see how far the passage departs from its own norm.
Frequently Asked Questions
How do I find the longest word in a text?
Paste the text into the finder and run the search. It scans every alphabetic word and reports the longest one, its length, and the average word length for the same passage.
Does the finder include hyphenated words?
Yes. A compound such as state-of-the-art is treated as one word, and its length includes the hyphens, so it reports 16 characters rather than 13.
How are ties between words of the same length handled?
The first word to reach the longest length is kept. In a passage where quick and brown both have five letters, quick is reported because it appears earlier.
Why does the longest word sometimes look shorter than expected?
Tokens that begin with a digit are skipped, and a word is truncated at its first character outside A to Z. A word containing an accented letter therefore measures shorter than it appears, which can hide the real longest word.
Can I use it to find the longest word in a word list?
Yes. Paste the list with one entry per line. The word total confirms how many entries were read, and the reported word is the longest single entry.
