Text Statistics

Deep analysis of any text — readability, vocabulary, sentence complexity, and more.

About this tool

Text Statistics

Text Statistics runs a deeper analysis than a word count: readability scores, vocabulary richness, sentence complexity, and paragraph structure, all from a block of pasted text.

What the measures mean

Vocabulary richness is the ratio of unique words to total words. A low ratio means heavy repetition, which is sometimes deliberate and often a sign of a draft that needs editing.

Sentence complexity comes mostly from average sentence length. Long sentences are not automatically bad, but a document where every sentence is long is tiring to read, and one where they are all short reads as choppy. The useful signal is variation, not a single target number.

Worked example

Reading vocabulary richness:

  • Total words1,000
  • Unique words300
  • Ratio0.3

Result: A low ratio means heavy repetition. Sometimes deliberate, often a draft that needs editing.

When it helps

  • Diagnosing why a draft feels heavy without being able to say why.
  • Checking that writing matches the reading level of its audience.
  • Finding paragraphs that have quietly grown to twice the length of their neighbours.
  • Comparing your own writing across pieces to spot habits.

Common mistakes

  • Optimising for a score. Readability formulas measure sentence and word length, not clarity, and you can score well while making no sense.
  • Applying general readability targets to technical writing, where necessary terminology is long by nature.
