We were concerned about ensuring we have the right size for a storage shed so that we could book it ASAP. We had 3 choices of shed size. 3m x 3m, 4m x 3m & 4.5m x 3m. I figured that we would be pushing it with a 3x3 but a 4.5x3 would be overkill. The solution was to list the main items to be stored, measure them up & build scale paper models of them. Turns out the 4x3 is the right size.
It will save us some pain when it comes to moving furniture. As in my line of work, it is always better to change/re-arrange things on a drawing or model, than when it comes to doing it full scale. It will make it so much easier to plan which bits of furniture to move first so that we aren't double handling.
