SWIMMING POOL (OLYMPIC SIZE)
An Olympic-size swimming pool is the type of swimming pool used in the Olympic Games, where
the race course is 50 metres (164.0 ft) in length. This is typically referred to as "long course",
distinguishing it from "short course" which applies to competitions in pools that are 25 metres (82.0
ft) in length. If touch panels are used in competition, then the distance between touch panels should
be either 25 or 50 metres to qualify for FINA recognition. This means that Olympic pools are
generally oversized, to accommodate touch panels used in competition.
An Olympic-size swimming pool is used as a colloquial unit of volume, to make approximate
comparisons to similarly sized objects or volumes. It is not a specific definition, as there is no official
limit on the depth of an Olympic pool. The value has an order of magnitude of 1 Mega-Liter .
Specifications
specifications for an Olympic-size pool are as follows:
Physical property Specified value
Length
50.000 m
Width 25.0 m
Depth 2.0 m (6 ft 7 in) minimum, 3.0 m (9 ft 10 in) recommended
Number of lanes 10
Lane width 2.5 m (8 ft 2 in)
Water temperature 25–28 °C (77–82 °F)
Light intensity minimum 1500 lux (140 footcandles)
2,500,000 L (assuming a nominal depth of 2 m.)
Volume 2,500 m3 (88,000 cu ft) in cubic units.
About 2 acre-feet.
There must be two spaces 2.5 m (8 ft 2 in) wide outside lanes 1 and 8 (in effect, two empty lanes). The
length of 50 metres (164 ft) must be between the touch pads at the end of each lane, if they are used. If
starting blocks are used, then there must be a minimum depth of 1.35 metres from between 1.0 metres
from the end of the pool to at least 6.0 metres from the end of the pool. At all other points, the
minimum depth is 1.0 metres. If the pool is used for Olympic Games or World Championships, the
minimum depth is increased to 2.0 metres.
