**What is a Lap in Swimming? Lap vs Length**

Some definitions/logistics before we move forward. To count laps in swimming, you need to know what a lap actually is. So what is a lap in swimming? And is a lap different from a length?

To help put the record straight, a lap and a length **are the same things** in swimming. This is because, in swimming, a lap/length refers to the course of the pool. Ie., how long a pool measures going one way. Such as a 25 or 50-meter pool.

A lap refers to swimming from one end of the pool to the next. Without a doubt, it’s one end of the pool to the other. It’s not back and forth.NPR podcast: How To Do Everything

Completing one full distance of the pool is the same as completing a lap or length of the pool. So when it comes time to count your laps, remember that the 100 (25 yards or meters) you swam isn’t 2 laps of the pool. It’s 4 laps. Or 4 lengths.

**1. Counting Laps by Distance**

I count laps by distance swam. Usually by 25 or 50, based on the length of the pool. This is best if you’re wanting to keep track of the total distance swim in your swimming workout.

I like it because it’s easier math for me as I don’t have to worry about how many 25s or 50s are in a set distance. I just keep counting lengths by distance until I reach the distance I need to swim.

An example would be swimming a distance of 200 yards/meters and counting each 25. And with each lap completed, add the finished lap to the count. So 25, 50, 100, and so on, up to the desired distance.

This is usually for any distance over 100, as anything under 100 typically doesn’t warrant counting. I pretty must just sort of swim it when it’s that short!

One of my teammates likes to count distances by 50 (in a 25-yard pool). Whereas I like to count by 25.

**2. Counting Each Lap Swam**

Probably the most common option for swimmers is to count laps by each lap/length that you swim. This works best if you’re trying to get the total number of laps you swam during a workout.

While this style of counting laps is more common with lap swimmers, I do have another teammate that counts each lap swam. They know it takes 8 laps to finish a 200 (in a 25-yard pool). And will count each lap as they swim by the lap number they’re on.

**3. Backwards Counting**

Admittedly, not many people count this way. In fact, I’m probably the only one who does it. But it’s a fun challenge that can help take some of the boredom away that can come with swimming. When my team does longer distance sets, such as 4x1000s, I’ll count two of them backward. Just for my amusement.

To count your laps backward though, you need to know the total distance or number of laps you plan to swim during your workout. And then start counting backward as you go. Again, this isn’t a typical method of counting. But if you want to give it a shot, you should try it one time!

**Quick Lap to Distance Table (by Length of Pool)**

For your reference, we’ve listed the number of laps and calculated the total distance for each lap swam. These are broken out by the length of the pool and can be used as a quick guide 🙂

**How to Calculate Laps in Swimming into Distance**

Telling people you swam 70 laps doesn’t mean much to most people. Competitive swimmers included.

Non-swimmers might be impressed with the high number, but ultimately, they don’t have an idea of what ‘70 laps’ means.Telling them you swam a mile though gives a bit more depth to your workout. A distance is much easier to visualize than several dozen laps.

*Related article*: **How Many Laps in a Pool is a Mile?**

So how do you calculate those laps you swam into a distance? The good news is that it’s not that difficult to calculate. You just need to know two things.

**Length of the Pool**

First, you need to know the length of the pool you’re swimming in. There are three types of pool lengths for lap swimming. Some others may exist that vary in length, but 99% of the time, it’ll be one of the three covered below.

**50 Meter Pool**: This is the distance used at the Olympics for swimming and other international swimming competitions. You’ll know you’re at a 50-meter pool because it looks like it never ends. 😀**25 Yard Pool**: Nearly every pool at the gym, neighborhood pool, and natatorium in America is a 25-yard pool (or is a 50-meter pool broken into two 25 yard pools). This is due to America being the only country not using the metric system. High school and collegiate swimming, including NCAAs, all compete in 25-yard pools.**25 Meter Pool:**The rest of the world uses 25-meter pools for training and competition. Don’t let the somewhat similar name fool you. The 25-meter pool is slightly longer than the 25-yard pool. In international swimming, the 25-meter pool is used.

It’s important to know that a 50-meter pool is double the length of a 25 length pool. So when counting laps in a 50-meter pool, it would go 50, 100, 150, 200, and so on. Whereas a 25 length pool counts laps as 25, 50, 75, 100, and so on.

If you have a pool that’s longer or shorter than these distances, that’s okay! You can still calculate the distance swam once you know how long your pool is 🙂

**Formula to Change Laps into Distance **

Now that you have the distance/length of your pool, multiply the distance by the number of laps you swam by the formula shown below.

**Formula**: # of laps swam X distance of pool = total distance swam

**Example**: 200 (laps swam) X 25 (25-yard pool) = 5000 yards total

Now divide your total distance by 1760 (for yards) or 1609 (for meters) to get the number of miles you swam.

5000 (yards total)/1760 (miles in yards) = 2.84 miles swam

If you’re looking for kilometers, divide your total distance by 1000

You can also use the conversion in Google or any other conversion app you may have to automatically calculate the distance.

**Alternatives to Counting Laps in Swimming**

Counting lap after lap is boring. I’ll be the first to admit it. Just as I’ll be the first to admit that it’s easy to miscount a lap here or there.

The good news is that several fitness trackers can count your laps as you swim. You’ll need to set up the length of your pool before you get started but once done, you’re good to go! One thing to note is that some of the fitness trackers don’t track when you’re kicking. They’ll only track when you’re swimming, due to the device being on your wrist.

If you plan to kick a couple of lengths of the pool, you’ll need to manually add this to your swimming total after your workout.

Some good fitness trackers are:

**Garmin Swim 2**: This watch will count the distance as you swim, along with how many strokes you take per lap. It’s not exactly a smartwatch if that’s something you’re also looking for, but it’s great for swimming and other sports.**Apple Watch**: When looking at Apple Watches, you’ll want to look at newer series, as older series aren’t waterproof or ideal for swimming. The Series 5 and 6 though are waterproof enough to take with you swimming and will count your laps.**FORM Swim Goggle**: If you’re like me and you don’t like swimming with a watch on, you can opt for the FORM Swim Goggle. This goggle has a built-in display that tracks your laps as you go. Once your workout is over, you can download your swim to the app to review your metrics

**Low Budget Lap Counting Devices**

Some waterproof fitness trackers aren’t the easiest on the wallet. And for some, it’s more of a distraction than helpful.

One incredibly affordable option and alternative to a fitness watch (or goggle) is the **SportCount Chrono 200 Lap Counter.**

This nifty little device sits right on your index finger and is a low-tech way to count each lap you finish. All that’s needed to count each lap is tap the button at the bottom of the counter with your thumb. And that’s it!

It may be a bit more manual than other swimming lap counters. But it’s an affordable price that gets the job done. You can find this lap counter on either **Amazon **or **SwimOutlet**.

**In Closing**

Despite the confusion and debate regarding a lap vs length, counting laps when you swim isn’t difficult! And once you know your lap count, you can brag to all your friends about how much you swam.

As always, happy swimming!
