A pickleball court is basically a badminton court with 2 differences. First the net is lower on a pickleball court vs a badminton court and second the no service line in badminton is 6.5 feet from the net vs the no volley zone in pickleball at 7 feet from the net.
A pickleball court is 44 feet deep from the back of each baseline (2 inch wide lines) and 20 feet wide. The no volley zone or kitchen is 7 feet (back of the line) from the center of the net. Each service box is 10 feet wide and 15 feet deep. The net is 34 inches high in the center and stretches the length of the court.
There is no difference between a doubles court and a singles court in pickleball.
