I thought I would put links to the publishers I’m aware of who sell graded readers in French. As usual, some have disappeared, but some still exist.

Wayside Publishing have some beginner readers that work well for those with an English speaking background. They have strict vocabulary control, using a very small vocabulary, lots of French-English cognates, and repetition. The smallest vocabulary, in Édi l’elephant, is 55 words in a text of 2100 words.

TPRS Books also has a range of books that follow the same approach of small vocabularies and much repetition, with some using base vocabularies below 100 in size.

CLE International have over 300 graded readers, some targeting specific age groups, and covering levels from A1 to B2. Their rebranded Lectures Découverte series (was Collection Découverte) are generally easier than A2 readers from other publishers (and other series) in my experience and their A1.1 stories are very easy compared to those typically labelled A1. I’m slightly frustrated that vocabulary sizes are no longer published, since they are quite relevant to the person reading, if not for the person assessing language level.

CIDEB also have a good range of graded readers (in multiple languages).

Editions Maison des Langues have a small range of graded readers. I get the feeling that they used to have more, since I’m sure I have read some that are not listed on this page. I have read and enjoyed the Alex Leroc series and various other books. From memory the A2 offerings felt more difficult than the CIDEB ones of the same level.

ELI have materials in multiple languages, and publish some beginner books that claim to be based on 100 words of vocabulary. I have a few of their books. The children’s A1 books are much easier than their adult A1 books, which I found quite challenging (in German). Note that if you are learning multiple languages, some of these stories are published in additional languages.

Hachette have their LFF range of graded readers, going from A1 to B2. It looks that they currently sell via specific distributors in different countries. I’ve read some of their A1 Albert et Folio books, which are easy A1 stories. I think the adolescent A1 stories are slightly harder. I’ve also read some of the A2 stories for adolescents. The B1 stories start to use passé simple.

Didier have a small collection of graded readers from A1 to B2. I’ve read Victor Hugo habite chez moi, which was pretty cute from memory. The Didier website is pretty horrible to navigate though.

Egmont has their Easy Readers, which are stories that have been adapted to learners. They are available via Languages Direct, who also sell readers from other publishers.

Teen Readers was a Danish publishing house that published graded readers in several languages. They seem to have disappeared since I last looked. You can buy some books online at Amazon and elsewhere. Similarly for Oxford University Press and Cambridge University Press. They used to have graded reader series suited to those with an English-speaking background. Some may be findable in the secondhand market.

National Textbook Company also seems to have disappeared, sadly. They had some beginner and intermediate level readers that were quite good.

In addition to these major publishing houses, there are independent authors publishing stories for people learning French. I have links to representative works in my list of French graded readers.
