The 165 feet is the total of two sides I think you'll find. So dependant on the width lets say 55 feet, then the length of the plot would be 110 feet.

My plots came ready marked out and I have never really measured them properly but the above sounds about right. Mine have got to be each approx 12 meters wide and with three side by side it is almost square, so they have to be 30+ meters long
