PROJECT → BIN → SHELF
Will it fit in the bin?
Will the bin fit on the shelf?
Check both before you buy storage. Measure your packed project, the bin’s inside and outside, and its shelf space.
For example: a paper-model kit may fit inside a box, but the closed box can still be too tall for its shelf. This checker catches either problem.

A dimensional check, then a real-world trial.
Measure the bin’s narrowest usable inside space under its closed lid. Tapered walls, corners, handles and rims can make a listed outside dimension misleading. Keep width and depth in the same orientation when measuring the inside and outside.
This compares rectangular spaces. It does not arrange loose objects, check a carrying route, validate a shelf’s load capacity or establish safe storage. Try one bin with the actual project and follow the container and shelf instructions before buying multiples.
