I like your space and size calculator, Matz, it is about right on. I believe the Association's calculator shows a 10x10 for a small 2 bedroom apartment whereas yours suggests using a 10x15. Even that is on the small side, but often big enough. Usually, out here in the West, we need a 10x20 for a 2 bedroom apartment or condo, especially if the family has been together for a few years and has collected "valuables" along the way.

Apparently there is some thought that giving the price of a 10x10 instead of a 10x15 or 10x20 sounds better to the caller, and, after they come in, you can show them the units and let them choose the larger unit that they will need. It's kind of deceptive, isn't it?

Self Storage Association, maybe you could revisit your unit size recommendations. Perhaps it's just outdated because people a saving more things these days.
