I define short middle-grade books as middle-grade books under 250 pages. Once we’re past that 250-page mark, it can be tough for beginning or reluctant readers. Personally, I’m good until page 400 — then my interest starts to dissolve. That’s why I’ve made this list of middle-grade books under 250 pages! There’s surprisingly a good number of short middle-grade books (I’ve read many on this list myself). However, I did go ahead and include a few additional picks which barely miss the mark at 256 pages but are also super quick and easy reads.
