"With its bright primary colors; cartoon illustrations; and readable, conversational text, this picture book will find a niche in most collections...Librarians and teachers could use this book to introduce units on size, measuring, or relativity. And it would be useful to demonstrate how to make beginning graphs in a fun, accessible way."--School Library Journal

"Amusing color illustrations and a whimsical text show how large items are dwarfed in size when compared to even larger things. Fun and informative."--The Horn Book Guide
