What size fabric bin fits a standard cube shelf like IKEA Kallax?
Reviewer consensus
A standard cube shelf opening is roughly 13x13 inches, so bins in the 10.5x10.5x11 to 13x13x13 range fit best. Several picks here (notably the Amazon Basics 10.5-inch cube) are sized for stack-in-cube use, while taller or trapezoidal bins like OrganiHaus and StorageWorks 3-packs are designed for open shelves and closets rather than cube cubbies.
