I created a comparison of lot size using LEGO pieces. It has every thing from Row up to Castle. One half shows the sizes using Village as reference, the other shows the size in 10 square meter units. Both with the exception of Row lots which are smaller. (1 LEGO stud or 1x1 Plate = 5 square meters, 2x2 Plate = 10 square meters) Notice the 90 degree offsets of the Village lots.
