Paste in text to see its average word length - a quick signal of vocabulary complexity and reading accessibility.
Average Word Length = Total Characters(in words) / Total Word Count
Example
A 9-word passage totaling 35 characters:
Average = 35/9 = 3.89 characters per word
The Typical Reference Range
Average English word length is commonly cited around 4.5-5 characters across general writing - text with a noticeably higher average often signals more technical, academic, or formal vocabulary, while shorter average word length often correlates with simpler, more broadly accessible writing.
A Component of Broader Readability Analysis
Average word length is one input several established readability formulas (like Flesch-Kincaid) use alongside sentence length to estimate a text's overall reading difficulty - this calculator isolates just that one component for a quick standalone check.
