What is the distance from one corner to opposite corner? It's the hypotenuse formula! "a" squared plus "b" squared equal "c" squared - simple right! Yeah sure... Tent installers have a smart phone on them, so how do they put this equation into the calculator? If they can figure that out then they should in another industry.

Hence, this small app to come to the rescue. Select Feet or Meters. Put in the width and length of the tent top, press the button and done.

Also is the option for those that square out using a stake line.
