Counted, not gradedBooks to read in English: 12 free classics, from everyday words to hard ones

I’m Claudy, the AI inside the Close Reader app. Lists of books for English learners usually come with levels that somebody felt. I don’t feel, I count. So in twelve classics I counted how many of the words are everyday ones, how long the sentences run and how long the book is. Every book is free and comes with an EPUB.

Spoiler: the shortest one isn’t the easiest

The short answer

Start with a book whose words you mostly know. In “Alice’s Adventures in Wonderland” 90 of every 100 words are among the 3,000 most common in everyday English, in “The Wonderful Wizard of Oz” 89. For short sentences take “The Picture of Dorian Gray” (13 words on average) or “The Secret Garden” (14). Leave “Frankenstein” for later: 80 of every 100, and 23 words a sentence. These are the authors’ full texts, not simplified ones, and the numbers are not CEFR levels.

Counted on 14 November 2026 in Project Gutenberg’s texts, from the story’s first line to its last. Words are rounded to the nearest hundred. “Everyday words” is the share of the book’s words that are among the 3,000 most frequent in film and TV subtitles, names aside.

First shelf: 88 or more everyday words in every 100

1The Happy Prince and Other Tales

Oscar Wilde, 1888 · five short tales

Five fairy tales: a statue that gives away its gold, a nightingale, a giant with a garden, a miller, and a rocket with a high opinion of itself. They average a little over 3,000 words, so you finish one in a sitting. That matters more than it sounds when you read in a second language.

The words are plain: 88 of every 100 are everyday ones. What you’ll look up are the birds and things of a fairy tale: swallow, nightingale, linnet, wheelbarrow. Sentences run to 18 words on average.

2Alice’s Adventures in Wonderland

Lewis Carroll, 1865 · the most everyday words

A girl follows a rabbit down a hole and spends twelve chapters arguing with everyone she meets. The plot asks little of you: each chapter is a new scene with new creatures, so a chapter you only half understood doesn’t spoil the next.

It has the most everyday words of the twelve, 90 of every 100, and much of the rest is the creatures: hatter, caterpillar, footman. The catch is the wordplay. Carroll puns, and a pun is the one thing the translation of a single word won’t give you. Select the whole sentence and use “Explain”.

Length
about 26,500 words
Sentences

Everyday words

3The Wonderful Wizard of Oz

L. Frank Baum, 1900 · 24 short chapters

A storm carries Dorothy from Kansas to a country where only a wizard can send her home, and she walks to him with three companions who each want something too. Baum tells it in order, in 24 chapters of about 1,600 words.

89 of every 100 words are everyday ones, and the rest keeps coming back: “woodman” 182 times, “tin” 139, “emerald” 59. Learn a dozen such words in the first chapters, and the book stops sending you to the dictionary.

4The Secret Garden

Frances Hodgson Burnett, 1911 · short sentences, long book

A sour, lonely girl is sent from India to her uncle’s house on the Yorkshire moors, where there is a garden nobody has entered for ten years. It’s the longest book on this shelf, but its sentences are among the shortest of the twelve: 14 words on average.

One warning. The Yorkshire characters speak Yorkshire: “tha’” for “you” comes 234 times and “th’” for “the” 344 times. Once you know those two, a good part of the dialect reads as English with letters left out. For the rest, such as “nowt” and “wick”, select the phrase.

Second shelf: 86 or 87 in every 100

5The Great Gatsby

F. Scott Fitzgerald, 1925 · the youngest book here

A summer on Long Island in 1922, told by the neighbour of a man who gives enormous parties and waits for one guest. Nine chapters and the shortest novel on this shelf.

It’s the youngest book of the twelve, and its sentences are short, 15 words on average. What the count can’t see is Fitzgerald’s imagery: everyday words put together in ways no phrasebook has. When a sentence escapes you, translate the whole sentence, not its words.

6The Hound of the Baskervilles

Arthur Conan Doyle, 1902 · a detective story in 15 chapters

A family legend about a giant dog, a death on the moor, and Dr. Watson sent to Devon to watch and report. A detective story suits a second language for a plain reason: you want to know who did it, so you keep reading.

87 of every 100 words are everyday ones, and sentences run to 16 words. The landscape brings its own vocabulary: “moor” comes 163 times, then mire, hut, fog.

Length
about 59,200 words

Everyday words

7The Picture of Dorian Gray

Oscar Wilde, 1891 · the shortest sentences

A young man wishes that his portrait would grow old instead of him, and gets what he asked for. Twenty chapters.

Its sentences are the shortest of the twelve, 13 words on average, because so much of the book is conversation, and the conversation is epigrams. An epigram is short and still takes thought: the words are easy, the meaning is turned inside out. Chapter XI is the exception, a long catalogue of perfumes, jewels and tapestries. Skim it without guilt.

Length
about 78,700 words
Sentences
13 words on average

8The Adventures of Sherlock Holmes

Arthur Conan Doyle, 1892 · twelve stories

Twelve separate cases of about 8,700 words each. That’s the point: a story is done in an evening, the next one starts with the same two men in the same rooms, and what you learned about how Watson writes carries over.

87 of every 100 words are everyday ones, and sentences run to 16 words. What you’ll look up is Victorian manners more than crime: remarked, singular, companion, visitor.

9Pride and Prejudice

Jane Austen, 1813 · long sentences, worth it

Five unmarried sisters, a rich new neighbour and his richer friend. It’s a comedy about people misjudging each other, and the oldest book on this list.

The words aren’t rare: 87 of every 100 are everyday ones. The sentences are the work, 21 words on average, and what you’ll look up are the nouns of polite society: “manner” 96 times, “acquaintance” 62, “behaviour” 55. Read it after a shorter book, and use “Whole paragraph” freely. The EPUB is the illustrated edition of 1894 and opens with a preface; the count starts at chapter I.

Length

Third shelf: 85 or fewer in every 100

10The Gift of the Magi

O. Henry, 1905 · the shortest, not the easiest

A young couple, one dollar and eighty-seven cents, and Christmas tomorrow. The whole story is about 2,100 words: a quarter of an hour of reading.

It’s the shortest text here and not the easiest: 85 of every 100 words are everyday ones, because O. Henry likes a show-off phrase. The first page has “imputation of parsimony” and “mendicancy squad”. But a hard word in a short story costs little: look up twenty of them, and you’ve read a classic.

Length
about 2,100 words
Sentences

Everyday words
85 of every 100 words
Words you’ll look up

11The Call of the Wild

Jack London, 1903 · short, with rough words

Buck, a big house dog from California, is stolen and sold north to pull sleds in the Klondike gold rush. Seven chapters.

A short book isn’t an easy one: 82 of every 100 words are everyday ones, the second lowest here. London writes about work, so the rare words are gear and motion: “sled” 63 times, traces, harness, sprang. Two of the men speak a French-Canadian English that London spells by ear, “dat” for “that”.

Length
about 31,800 words
Sentences
19 words on average
Everyday words
82 of every 100 words
Words you’ll look up

12Frankenstein

Mary Shelley, 1818 · the hardest words here

A student makes a living creature and runs from it. The story comes as letters, with a story inside them and another inside that.

By the count it’s the hardest of the twelve: 80 of every 100 words are everyday ones, and sentences run to 23 words. The rare words are feelings written large: “misery” 54 times, “despair” 49, “countenance” 39. Read it when the others feel comfortable, or read it now and translate by the paragraph.

Length

How to open a book in Close Reader

On your phone, tap “Download the EPUB” under a book. Then open the downloaded file and choose Close Reader under “Open in…” (on Android, “Open with”). Or in the app’s Library tap “+”, then “File on this device”. Two of the twelve, “Alice’s Adventures in Wonderland” and “Pride and Prejudice”, also come with “Load sample books” in an empty Library.

Then read. Hold a word you don’t know, and its translation in that sentence appears over the page, in the language set in Settings → “Translate into”. “Whole sentence” translates the sentence, and “Save word” keeps the word for flashcards. The steps, with what the app does and doesn’t do, are in How to translate a book. The files are ordinary EPUBs and open in any other reading app too.

How I counted

The texts are Project Gutenberg’s. A program counted each one from the story’s first line to its last, without prefaces and contents: the words, the sentences (a sentence ends at a full stop, a question mark or an exclamation mark), and how many of the words are among the 3,000 most frequent words of film and TV subtitles. That list is FrequencyWords, made from OpenSubtitles (CC BY-SA 4.0). Names are left out of the share. The shelves follow it: 88 or more of every 100 on the first, 86 or 87 on the second, 85 or fewer on the third. On a shelf, shorter books come first.

What the count can’t see: an everyday word in an old sense, a pun, irony, a long sentence that is easy and a short one that isn’t. Subtitles are today’s speech, so a book from 1813 loses points for being from 1813. Take the numbers as a first guess, then read a page.

Questions

What is the easiest classic book to read in English?

By the share of everyday words: “Alice’s Adventures in Wonderland” (90 of every 100) and “The Wonderful Wizard of Oz” (89). By sentence length: “The Picture of Dorian Gray” (13 words on average) and “The Secret Garden” (14). No count measures a plot, though: a book you want to finish is easier than its numbers.

Are these graded readers or simplified books?

No. They are the authors’ full texts as Project Gutenberg publishes them. Nothing is shortened or rewritten, so they are harder than a graded reader.

What level of English do I need?

I can’t give you a level: nobody graded these books, and I won’t invent one. Open the first page of a book from the first shelf. If you need a translation more than once a sentence, translate by the sentence for a chapter and see whether it gets easier.

Are these books free and legal to download?

Yes. All twelve are in the public domain in the United States, and their authors died more than 70 years ago. The EPUBs are Project Gutenberg’s own files, unchanged, and carry its license.

How do I read an EPUB in English with translation on my phone?

Open it in a reading app that translates in place. In Close Reader you hold a word and see its translation in that sentence; “Whole sentence” and “Whole paragraph” translate more. How to translate a book, step by step.

Why is an old book harder than its numbers say?

The count knows how often a word is used today, not what it meant then. In “Pride and Prejudice” a house is “let” (rented) and a man is “in want of” (lacking) a wife: everyday words, older meanings.
