The definition of an Olympic size swimming pool is 10 lanes each 2.5 meters wide, however to prevent the outside lanes being disadvantaged by having to compete with the waves bouncing off the sides of the pool only the middle 8 lanes are ever used.
8 or 6
Competitive swimming pools widely vary in width. The width (in feet) changes depending on how many lanes it has. Most competitive pools have either six, eight, or ten lanes. An official Olympic sized swimming pool is 50 meters by 25 meters. It is ten lanes wide.
There are many different kinds. The most common is 6 lanes. There are also a lot of 8 lane pools.
