Underhand serve below the waist; drop-serve permitted (USAP 2021+ rule adopted); Service must clear NVZ; lands diagonally in opponent's service court; One-fault rule (no second-serve)
Why people argue about this
People often assume that in Pro Pickleball, a service must be below the waistline and clear of the non-volley zone (NVZ) just by looking at it visually. However, the actual implementation requires precise observation using an official net height gauge to ensure compliance with the rule, leading to many misunderstandings and arguments about whether a serve has been correctly executed.
