How To Measure and Replace Trampoline Springs

When we purchase a new trampoline for our backyard, we rarely consider the fact that it will most likely need maintenance and potentially repair at some point. It's highly probable that some springs will need replacing, especially if you've enjoyed many hours of happy bouncing. You may think that this needs the expert eye of a professional, but this couldn't be further from the truth. In fact, it's perfectly possible to replace springs on your trampoline yourself without breaking too much of a sweat.

All you need is a little know-how. So, how is it done? Well, you'll need to know how to measure trampoline springs. Once you know your trampoline sizes, you can use our handy guide to help you. This article is crammed full of tips and information, so you can finish the job with confidence.

How to measure trampoline springs

Before you think about replacing your trampoline springs, you'll need to establish the correct size. It is absolutely vital to use the correct size for your trampoline model in order for it to function properly and safely. Whilst this may sound like a no-brainer, there is a proper way to do this to make sure your measurements are spot on:

  • 1. Remove 3-4 springs from the trampoline. You will need to measure several to check your measurements are accurate. This can be done by unhooking them with pliers. There is a possibility of springs pinging off, so it's not a bad idea to wear safety goggles and some gloves to protect from any sharp edges.
  • 2. Lay the spring flat. Of course, it should not be under any tension at the time when you measure. If the spring has been stretched out of shape, you'll want to measure ones that are in good condition or your measurements will be too long.
  • 3. Measure the length of your springs. This means measuring right from the end of one hook to the other.
  • 4. Turn your spring upright and, at the end, measure the diameter of the spring (from side to side of the circular end).

Trampoline spring sizes

There are several spring sizes available for trampolines, and as we have already mentioned it is very important to choose the correct one. Here are the most common sizes:

  • 5.5 inch trampoline springs
  • 6.5 inch trampoline springs
  • 7 inch trampoline springs
  • 10 inch trampoline springs

Heavy duty trampoline springs

Nowadays, you can readily purchase heavy duty trampoline springs. We think these are a great option, as they will provide extra strength and therefore will need replacing less often. Also, these springs are made from galvanised steel. This is a big bonus as they will resist rust when they get wet during rainy weather. Finally, these springs will resist cracking, which is a real risk during a cold snap.


How many springs are on a 12-foot trampoline?

How many springs are on a 14 ft trampoline?

How many springs are on a 15ft trampoline?

Like a 14 foot trampoline, a 15 footer most often has 96 springs.

Getting trampoline springs off

Before you can replace your trampoline springs, you'll need to remove them. Luckily, this isn't tricky to do. Here are our top tips:

  • 1. Ensure the jump mat isn't under tension. While this may sound obvious, make sure your kids aren't sitting on it while you work, or the job will be a nightmare!
  • 2. Protect yourself. Springs ping, and trampoline springs are no different! So, protective goggles are a great idea to guard against any mishaps if you have them. Also, trampoline springs can be rusty, rough, or have sharp edges. Thick protective gloves will protect your fingers from any nasty nicks or grazes.
  • 3. Now you're ready to remove the springs, you have two options. First, you could use pliers to prise the spring hooks from the loops. While this is the most common method, it can be fiddly. Otherwise, you can use a special spring removing tool. This leads us nicely on to our next important point.
