Is there a difference between a pickleball court and a badminton court?
A pickleball court is basically a badminton doubles court (both are 20 ft x 44 ft) with three significant differences:
the net is lower on a pickleball court versus a badminton court,
the no service line in badminton is 6.5 feet from the net versus the no volley zone in pickleball at 7 feet from the net, and,
badminton has different lines for singles and doubles play, pickleball does not.
