In the UK (mainly due to the weather) pickleball tends to be played indoors on a badminton court with a lowered net. The net should be 36 inches high at the sides and 34 inches at the centre so if you haven't yet bought a portable pickleball net then lowering the top of the badminton net to half-way down the badminton net poles is usually the right height. It's great fun to play pickleball outdoors when the weather is good and it's pretty easy to set up a temporary court if you have a flat area 44 feet by 20 feet (plus allowing some room to be able to run round the edge of the court) and a portable pickle or mini tennis net. It's often possible to fit a pickleball court on just one side of a tennis court so you can have one on each side of the tennis net for a pickle party! I have pickleball court tape and portable pickleball nets for sale on my site which you might need. Below is a useful video from the Pickleball Channel on how to measure and mark out a temporary pickleball court.
