Overview

Visualize and compare book dimensions with standard formats.

BookScale helps you visualize book dimensions before buying. When browsing book pages on supported sites, click the ruler icon to see a visual comparison with standard formats like A4, A5, US Comic, Manga Tankobon, or BD Album. Compare spine thickness with everyday objects like a matchbox or coin. Save books to compare them side by side.
