Swimming pool measurement

I received a few emails about the post I did on calculating pool volume. The question posed was, “how can you measure the pool easily?” especially in the cold, wet weather.

The most common way to measure a pool is with a measuringLaser rangefinder tape, but nowadays we use a digital laser rangefinder. It can measure up to 150 feet and will also calculate area and volume. It cannot measure pool depth through the water though, so we rely on more traditional methods to get depth measurements.

To make my pool measurements quickly I enlist the help of anyone nearby and take “readings” off of them. To measure the swimming pool depth I use the pool pole (from the net/ scoop/ vacuum head). I mark the water depth on the pole and can easily measure the pole on “dry land”.

Our laser tool has made measuring so much easier and quicker. I tend to carry spare batteries as well as my trusty old tape measures. I still use the old-style tape measure in bright sunlight for distances over 100 feet because I find it extremely difficult to find the laser dot. I suppose one day I’ll get the special sighting board and glasses or upgrade to a more powerful device. For now I’m just getting used to this little techno-toy and having fun while saving time.

  1. Do you think the make and model really matter? I figure if I only need to measure up to 60 feet I don’t need such an upmarket machine.
    Does anyone know how bright the laser on the cheaper gadgets are?

  2. I use an el-cheapo Chinese trash gadget. It is a few inches out in the results, but that’s close enough for me. I’m no pro so I use it for odd jobs around the house and yard.

    If I plant the new rosebush 3 inches too far, so what?! I have had it for a year or so. If it gives me another year of service then I’m happy.

  3. How do I measure my swimming pool. I have had it for several years and am in the process of ordering a new liner. I can not remmber the size of the pool. I think that it is 24′ round, but am not 100% sure.

  4. No doubt, a VERY useful device. I purchased a house a couple of years ago with a pool already built in. I spent forever trying to figure out how to measure the gallons of water it held.

  5. I was a lifeguard for 5 years in what seems to be a lifetime ago and checking measurements is obnoxious. Unfortunately we never had cool technologies like this. It would have saved me a ton of time.

  6. hey jess, where did you used to be a lifeguard? i did it in high wycombe but not for 5 years. i once fell in trying to do a measurement once

  7. Question: If I use a chemical test and keep my pH in line with that, why do I need to know the water volume? Is it important enough to spend the dough?

  8. I keep all the measurements and capacities on file for all of my customers. This information helps when making estimates for jobs or orders for chemicals, and allows for accuracy without having to revisit the pool.

  9. Good input on measuring pools. We have always used the lenght x width x average depth x 7.5 to help measure gallons of water in the pool.

  10. This is great information, the laser range finder is an excellent device to make volume calculations easier.

  11. Which is more economical to maintain? Saltwater pool or fresh water pool. I have an inground pool.

  12. An easy way to measure an odd sized pool is to use a walking measure tape, or to use a tape measure, and measure the circumference (outside edge) if you will of the pool. Take this measurement time (x) average depth times (x) 7.5 will give you the pool gallons.
