I am not totally sure but in a normal pool it can mean just up or up and back. To find out, ask how many metres you have to swim and then estimate.

∙ 15y agoThe length of a pool is a measurement from one end to the other; not from one end to the other and back again! One length is is therefore once down.

∙ 12y agoWhen I was swimming competitively, a lap was down and back. A "length" was just once down the pool.

∙ 12y agoYep! It's one way across the pool, but depending on the kind of pool your in it can still be a 50 or a 25

∙ 11y agoNo, that's a length. A lap is when you've swam to the other end and back.

no a lap is down and back
An Olympic pool is 50 meters in length so 50 meters would be one length of the pool .
1 lap, down and back.
Many people have different views on this. Most refer to a lap as one length of the pool. Others say is it down AND back.
Some people feel that a lap and a length are the same thing. They will use the terms interchangeably. Competitive swimmers do not often talk about lengths, but when they do they usually mean one complete length of the pool. As such, a lap generally refers to two lengths. For example in a 25 yard pool, a mile is ~35 laps, or ~70 lengths.Webster's II New College Dictionary uses the following definition for lap in regard to pools: "2.b. One complete length of a straight course, as in a swimming pool."
If you count a straight lap as a full lap, then 30. If you count a there-and-back lap as a full lap, then 15.
20 lengths of a 25 meter pool, or 10 lengths of a 50 meter pool. Some people refer to a lap as one pool length, while others refer to a lap as down and back (2 lengths). I haven't found which one is the correct terminology, but the term length has only one meaning (for the particular pool that you are using).
