Original-edition reading analysis
A short adventure with everyday vocabulary. The harder part is the narrator, who jokes with the reader and often says the opposite of what he means. Our recommendation for the complete original is Strong B1 to B2.
Updated

Short answer
Yes. Peter Pan is one of the shortest books in this collection and its vocabulary coverage is high. A strong B1 reader can follow the story; the narrator’s irony is the part that needs B2.
Vocabulary profile
The bars show the share of running word tokens—not the share of unique dictionary entries. Common words repeat often, so token coverage is the more useful signal for how frequently a learner may meet unfamiliar language while reading.
These are TeakReader frequency-based vocabulary bands, not official CEFR assignments for every word or an official CEFR certification of the book. They are most useful as comparative reading signals.

Transparent methodology
We downloaded the UTF-8 plain-text edition from Project Gutenberg ebook 16, removed the standard Gutenberg header and footer, lowercased English word tokens, and matched them against the same ranked frequency data TeakReader uses for vocabulary analysis. We then combined token coverage with editorial review of syntax, narration, dialect, historical context, and wordplay.
Vocabulary coverage is informative but not a complete readability score. Research on reading comprehension commonly distinguishes knowing most running words from understanding every sentence; syntax and background knowledge still matter. See this Cambridge overview of lexical coverage research for context.
