Ok I am new here, excuse me if this sounds dumb. I am having trouble with the way things are measured on this website. There are some rulers, but the ruler lines are sometimes hard to tell is it inches or centimeters. Then I see Soda Cans but not all Soda Cans are equal. Then there are forearm measurements. Well is anyone else confused? I would like to see some standard agreed upon, but I am not sure what would work? Any ideas out there. Enjoy all the pics but its really hard to understand what is being depicted in some cases.
