Behind the numbers

How this calculation works

Check the ideal straight-line clearance of a thin item along a box’s space diagonal.

THE FORMULAd=hypot(L,W,H), clearance=d−object length

A worked example

Dimensions 6, 8, 24 give a 26-unit diagonal and one unit of clearance for an item of length 25.

Good to know

This model treats the item as a segment with negligible thickness.
