How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or level where one is given. Three of the four listings give a reading age, one of them marked as from customers, and none give a grade level. How we pick explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best selling books for 15 year old boys

Check who the book was written for

The Double Dangerous Book for Boys names boys in the title and collects projects and tales. Turns Out I’m Actually Cool states it is written for girls 11 to 15, so it does not fit this list’s reader despite its strong listing. Best Mates and The Boy Who Could Do What He Liked both list a reading age of 9 and up, which skews young for 15. For more teen options, browse our young adult books.

Mind the format

Only two listings state a page count: 304 pages for The Double Dangerous Book for Boys and 122 for Turns Out I’m Actually Cool. The other two give no page count, so compare format instead: a project compendium, an animal-story collection and an illustrated novella. See new books for 16 year old boys and memoirs for teen boys for more ideas.

Before you buy

• Check the listed reading age against a 15 year old: two picks list 9 and up, one lists 11+ and one states none.
• Note who each book was written for: one pick here was written for teen girls.
• Confirm the page count on the listing: two picks here state no page count.
