I am needing to build some 4ft x 4ft kind of square shaped structures with one side missing. So i will have to bend two 90 degree bends and i want it to be a 4x4 square. What i am struggling with is figuring out how to measure the lengths of the legs with the 90 degree bends. Can anyone explain how to calculate the lengths with the bends in them?

A couple of things will factor in. What size of diameter of rebar, and what size of radius do you want in the corners where you want the bend? I know you can't figure a perfect sharp bend. You give me those two items and I'll figure you your length plus give you a drawing showing you how to figure it.

Use bender to make bend in a bar, after witness marking bar to holder of bender. Make a full size layout on bench or floor. Place bent bar with witness mark on base line, transfer witness mark to base line, flip bent bar over and into opposite corner and again transfer witness mark to base line , and last measure between witness marks on bars this is the deduct length. Deduct length is used to mark and make bends moving away from center of layout.

At work, we order all our bends from the yard.
At home, I usually just bend it rough then cut the legs to the desired length.
When your standing in wet mud, it's actually quicker than doing math in your head or on a wet 2X4.
