Serve speed is the velocity of the ball off the racket, shown on tour broadcasts in mph or km/h. It's calculated from the distance travelled and time taken. A strong club first serve is often 80-100 mph; professionals routinely exceed 110-120 mph, and the fastest recorded serves top 150 mph (240 km/h). Speed isn't everything — placement and spin often matter more than raw pace.

In practice
Serve speed in tennis has climbed steadily over decades of racquet and string technology improvement, with the fastest recorded professional serves now exceeding 250 km/h (155mph) — but raw speed alone doesn't guarantee an effective serve, since placement, spin variation and the ability to disguise serve direction until the last possible moment all meaningfully affect how difficult a serve actually is to return.
FAQ
What's the fastest tennis serve ever recorded?
The fastest officially recorded serves have exceeded 250 km/h (around 155mph), though exact record figures are periodically updated as new fast serves are measured at tournaments.
Does a faster serve always mean a more effective one?
Not necessarily — placement, spin, and disguise (hiding serve direction until the last moment) all meaningfully affect how returnable a serve is, independent of raw speed alone.
