How To Install A Trampoline On A Slope

We have talked previously about if you can have a trampoline if you have very little grass in your backyard (but still some concrete).

This is just one of the many situations you might run into with your yard.

Another situation is if your backyard is on a slope.

Can a trampoline be installed in a backyard that has a slope? The answer to that question is yes. You will need to invest some time and even some money to either build a trench on the up or bottom side of the trampoline, but it is possible to have a trampoline on a slope.

Read on to see how to determine how bad your slope is and figure out the best way to level the ground for your trampoline.

Determine the slope of your backyard

The first step in figuring out how you are going to install your trampoline is finding out what the slope of your backyard actually is.

Some websites will suggest that you need to have a wood plank that is larger than your trampoline to be able to find the slope.

Put the trampoline on the part of the yard you want to correct.

Then place the plank on top of the trampoline and also place a carpenters level on top of the plank going parallel to the slope.

Lift the plank on the downward side of the slope until the bubble in the carpenters level is between the two lines.

Then measure the distance between the top of the downward side of the plank and the top of the trampoline.

Once you have that distance in inches, divide the diameter of the trampoline in inches by the distance between the trampoline and plank in inches.

If the result is greater than 7, the slope is too much, and move your trampoline to another location.

If the result is less than 7, then you can use this area for your trampoline.

Dig the trench

According to

Move the trampoline out of the way and dig a trench under the area where the uphill legs of the trampoline will be placed. The depth of this trench should equal the total amount of slope you measured. Use the carpenter’s level to make sure the trench is level.

Move the trampoline back to its original position, with the uphill legs in the trench. The trampoline will be somewhat unstable because the side legs will now be higher than the uphill and downhill legs. Dig trenches under the side legs until both the uphill and downhill legs are seated firmly.

Check that the trampoline is now level in all directions, and adjust the trenches if necessary.

When you have finished the above, the trampoline might be slightly uneven.

If more than slightly, move the trampoline out of the trench and keep digging.

If slightly, then the jumping action will bury the legs of the trampoline and will eventually level out.

What to do with uneven ground

You will not always be working on level ground or on a slope.

Often you may have to work on ground that is uneven in different places.

You still have some different options for your trampoline on uneven ground.

Leveling blocks

There are many different leveling blocks out there that you can choose from, though most are built for cars and RVs instead of trampolines.

The Camco leveling blocks are a good choice to put on the ground underneath the trampoline legs to get them level with the ground.

Put them on the part of the ground that sinks the lowest and put as many as needed until that part of the leg is level with the rest of the trampoline.

This is a relatively inexpensive option for you to make your trampoline level.

Trampoline leveler

Another option is the trampoline leveler, which basically gives you extensions to the trampoline legs, allowing you to move the levels up and down to get a good balance on the legs.

The trampoline leveler attaches to the legs of the trampoline and then you can extend the legs of the leveler until the trampoline is level.

More trenches

On a slope you can build a trench to get your trampoline level.

The same can be done on uneven ground.

It will be a little more work, but you can do it and make jumping on the trampoline fun.

First, you have to decide if you want the trampoline completely above ground or if you just want to bury a certain part of the trampoline that needs to be level.

If you decide on putting the trampoline inground on the uneven ground, then start digging.

It will be quite a bit of work to dig a deep enough hole for the whole trampoline.

If you want the trampoline above ground, figure out how high the higher edges of the uneven ground are and dig until the uneven parts are even with the rest of the ground.

Then you can place your trampoline in the new area, put in your anchors, and then start jumping.

Cut the legs of the trampoline

Not a great option, but one that can give you the results that you want.

Cutting the legs of the trampoline would allow you to get the trampoline legs adjusted to where you need them.

Before you cut the legs, though, make sure of a few things:

  • That you never plan on moving the trampoline again. Once you cut the legs of the trampoline, there is no turning back. Those legs you cut are now gone and you will not want to move your trampoline to another area unless you purchase another trampoline.
  • You will need to have something that will cut through the steel. Make sure you have a proper saw to cut the legs and also a drill to drill new holes as needed.

Clear space around the trampoline

Whether you have your trampoline on a slope or on uneven ground, make sure to clear the area around the trampoline.

You are not going to want trees above you while you are jumping.

This could leave to some minor or serious injuries.

Keep the trampoline away from pools and houses, so you can avoid the temptation of jumping off or into these.

Also, make sure the trampoline is away from any animals you might have in your yard.

Do not forget your safety features

As always, remember to purchase a safety net and a spring cover.

This is especially important while jumping on a trampoline which is placed on a slope.

The slope makes it a little more dangerous if someone falls off the trampoline.

Not only do they leave themselves open for getting hurt while falling off the trampoline, but there is the potential they will start rolling down the slope as well.

The safety net will keep the jumper contained within the area of the trampoline and help them avoid rolling down the slope.


Even if you do not have a flat space in your backyard, you can still get and install a trampoline.

Keep in mind that you may need to spend some time digging a trench or two to level out the ground where the trampoline will be placed.

If needed, purchase a leveling kit or leveling blocks to keep your trampoline level.

And always make sure to take as many safety precautions as you can.
