8 lanes.
The 1924 Summer Olympics were the first to use the standard 50 meter pool with marked lanes. In the freestyle, swimmers originally dived from the pool walls, but diving blocks were incorporated at the 1936 Summer Olympics. --from wikipedia

it is 6' long and there are 12 lanes. LOL
8 or 6
It depends in the standard of the simming race, for Olympic or World Championships then the pool has to have 10 lanes however only the middle 8 are used. For lesser competitions it depends on how many lanes the pool has, usually a minimum of 6 however for smaller and older pools which are very rarely used there may be 4 or 5 lanes
An Olympic swimming pool usually has 8 lanes, but sometimes has up to 16.
There are many different kinds. The most common is 6 lanes. There are also a lot of 8 lane pools.
A pool divided into lanes has a bottom painted with black stripes, dividing the lanes apart. There are also heavy ropes stretched from one end of the pool to the other, dividing the lanes apart.
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.
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.
