This Desk Drawer Organizer is just slightly larger than the size of a sheet of legal paper - 8.5" x 14". It's very sturdy and looks nice on my desk but unfortunately I have a bad habit of just adding papers that need attention, bills and correspondence, etc. BUT it definitely does keep all these items organized even if unattended to!
