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.
when people swimming lanes divided by lane lines
8
it is 6' long and there are 12 lanes. LOL
8 or 6
White arrows in the middle of the lanes.
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.
By the swimmer's seed times coming into the race. The middle lanes are the fastest, and the outer lanes are progressively slower (that's why the swimmers often seem to be in a V shape) To be specific, the swimmer with the fastest time swims in lane 4, 2nd fastest in lane 5, third fastest in lane 3 fourth fastest in lane 6 fifth fastest in lane 2 sixth fastest in lane 7 seventh fastest in lane 1 eighth fastest in lane in lane 8.
Both lanes 4 and 5 are highlighted by using yellow lane ropes. The swimmers who compete in these lanes have either the fastest entry times or in the case of the final, the fastest qualifiying times. It is an advantage to swim in these lanes as often they are subject to less water turbulance than others. Spectators also can identify swimmers more easily by the use of the yellow lane markings.
An Olympic swimming pool usually has 8 lanes, but sometimes has up to 16.
10 but they only use the inside 8
