Last Updated on February 7, 2023

Installing a trampoline in the backyard, whole the family can be entertained together. But it’s important to set it up in a good location like a flat surface. While jumping on the trampoline, it should be leveled enough otherwise this can cause safety hazards. So, trampoline leveling is a must while putting it in the backyard.

Have you wondered if can I set my trampoline in the sloped backyard? Well, this is possible and you can do it in several ways. But it needs some investment and time. But how to install a trampoline on a slope or uneven ground?

Trampoline Leveling: How to Install A Trampoline on A Slope or Uneven Ground

how to install a trampoline on a slope or uneven ground

There are some steps to follow when you are trying to set up or install a trampoline on a slope or uneven ground. Those are as follows:

Determine The Slope of Your Backyard

First of all, you need to determine the backyard slope so that you can understand which leveling method will be more accurate there. The tools and accessories you might need to calculate the backyard angle are a wood plank, a carpenter’s level, and measuring tape.

Place your trampoline in the short term in the garden where you want to set it permanently. Then put a plank on the trampoline going parallel to the slope. Also, put the carpenter’s level on the top of the plank.

Now lift the downward side of the plank and observe the bubble of the level. When the bubble is balanced between the two lines, measure the distance from the trampoline top to the plank top on the downward side.

Then divide the trampoline diameter (inch) by the above-mentioned distance (inch). If the value is more than 7, the slope is very high. In this case, move the trampoline to another location where the value is less than 7. Now you can up the downward side of the trampoline in several ways.

Dig Trench for Trampoline Leveling

A traditional but effective way to level the trampoline in the sloped garden is by digging a trench in the upper side and placing the trampoline legs there. Make sure, the trench depth and the measured height are equal. You can use a level to measure the accuracy of the depth.

After inserting the legs of the upper side in the trench, check again the uniformity of the trampoline. If you feel, some legs are still up, adjust the trench depth again.

Add Soil on Down Side to Level Trampoline

This is the opposite of digging a trench. To make smooth to your trampoline, fill the down-slope side with soil, mulch, sand, and other materials. But packed the ground well. Or make a concrete base but consider the safety aspects. This process works quite well but costs more.

How to Set Up A Trampoline on an Uneven Ground

When the backyard is very much uneven in different places instead of a continuous slope. In this case, installing the trampoline in the trench will still work but there are several other good alternatives to do that smartly.

Trampoline Leveling Kit

This is an effective option that you can apply for your trampoline. Levelers are actually an extension to trampoline legs. These leveler kits are made of heavy-gauge steel and provide great durability. They allow them to up and down the level to balance amongst the legs.

After attaching with trampoline legs, extend or lessen the leveler heights to get proper leveling. Typically levelers can be locked using nuts or clamps with trampoline frames that prevent moving the frame when jumping. Each leveler comes with maximum load-carrying capacity and doesn’t exceed the limit.

Trampoline Leveling Blocks


To level the trampoline, leveling blocks are used. They are mainly made for cars and RVs. But they are simultaneously effective for trampolines. They are stackable so you can increase or decrease the block height by attaching or detaching them.

The interlocking system allows locking one block with another to make the whole block durable. They are inexpensive, and lightweight but provide durable leveling.

Putting these underneath the trampoline, you can easily level the trampoline in uneven locations. Put them in different spots on the trampoline as many as you need to level.

Trenches for Trampoline Leveling on Uneven Ground

Like trenching method in a sloped garden, you can also apply this process in an uneven backyard. But the difference is, in this method you have to make whole underneath the complete trampoline base instead of the upper side. You can also sink the trampoline and make an in-ground trampoline.

If you want to put the trampoline up as an above-ground trampoline, measure the trampoline, and dig the hole as much as you want to bury the trampoline. This may need a digging drain for stagnant water passing.

For making an in-ground trampoline, dig a large and deep hole. Make a retaining wall and drain then install the trampoline there. Put anchors, secure the trampoline, and jump. Take proper care of the sunken trampoline problems and you can enjoy it a lot.

Frequently Asked Questions on Trampoline Leveling


a. Can I cut the trampoline legs to level the trampoline?

Answer: Yes, you can do it, but this is not a professional approach. If you need to move the trampoline in the future, this will be awkward. You can do this in two conditions only- if you place the trampoline permanently and you have all the essential things (like a saw, drill) to cut the legs and make holes again.

But some trampolines come with trampoline adjustable legs, you can choose these models to level the trampoline in an uneven backyard.

b. What types of safety do I need to install a trampoline in uneven or sloped areas?

Answer: A safety net and spring cover is a must to ensure safety to prevent falling and getting hurt. Also, level the surrounding of the trampoline so that jumpers don’t get heavy impact if they fall on the ground. Besides, leveling the surrounding will help to roll down the slope.

c. How to level a trampoline on grass?

how-to-level-trampoline-on-grassAnswer: You can use some wood blocks as levelers for the feet of the tramp. For a 12ft trampoline, you may need 2*4 blocks as feet support which will be attached to a 3′ extension from below. Strong screws like 2″ or 3″ should be used here.

You can keep the grass untouched for this type of leveling. The number of wood blocks would vary for each part of the leg according to the ground height.


If you don’t have a smooth yard to set the trampoline, don’t be worried. You can install the trampoline there without any big hassle. And, hopefully, the article on how to install a trampoline on a slope or uneven ground will be a masterpiece to understand and do the task easily.

Whether you use leveling kit, leveling block, or dig a trench, you have to spend some money and time. But you can make your trampoline bed leveled for a great bounce. Have fun games on a smooth trampoline bed!
