Shelf and bin fit check

How many of these bins fit this shelf?

Measure between supports, behind doors, and below the shelf above. Then reserve the space your hands need to pull a bin out.

Measured result

Count usable rows and columns

Use the shelf interior, the filled bin, and the lift-out room your hands need.

Rectangles are the optimistic case

Tapered sides, lips, handles, hinges, shelf pins, and bowed walls all steal space. Use this to reject bad combinations, then test one real bin before ordering twenty.
