How this is worked out
Floor area is the storage volume ÷ the height you can safely stack to.
Worked example
- Volume 10 m³
- Stacking height 2 m
10 ÷ 2
5 m²
Assumptions and limits
- Assumes solid stacking to the full height with no access aisle, so add space if you need to reach items during the let.
- Heavy or fragile items cannot be stacked high, and storage sites impose their own height limits.
