But again I really have to stress the joint layout. This attached pic is 4 inch thick sidewalk. Its ten feet wide at this spot. The sidewalk is six foot wide coming into this ten foot. Notice I put a centerline at six feet and my cross joints are 5 feet apart. With 4 inch, you really need small panels. I cant tell you how many driveways I have seen that have a massive nasty longitudinal random crack because the concrete guys didnt think it needed a centerline. Anyways, good luck with your project however you go with it.
