We were shopping for storage on Saturday. As we were looking at spaces, some were looking a bit small for the size we were being told they were. For example: at one storage place, the 8×10 measured out to be more like 6 1/2 x 8-something of MY feet (I wear an average size for a woman). After looking at a few spaces that looked suspiciously smaller than the quoted size, we decided to go home for a tape measure. Not to be difficult, but because I want to maximize the space I’m going to be renting, so I’m going to line the walls with gorilla racks, wardrobe boxes, and the center with bakers racks on wheels. Exact measurements are needed to figure out what size space I need to rent.
The tape measure turned out to be quite useful and helped later when I was laying out the floor plan and comparing costs. The salespeople at both places watched us suspiciously until we explained why we were measuring. Who cares what they think anyway, they aren’t the ones paying for it….
The moral of the story, don’t believe everything you hear or read. Sometimes you have to check for yourself. Don’t believe everything you hear or read. Companies often provide misleading information until they are caught, if they ever are.
Bordering on brilliance... 
I noticed that you didn’t include the actual measurements. From this I will deduce that the measurements are accurate and your feet are about 15 inches long. 🙂
