How to Level a Trampoline: Levelling a trampoline is essential for safety. Clear the area, use a spirit level to adjust legs, and ensure stability. Regular checks maintain safety. Get step-by-step instructions now!

What Are the Top Methods for Levelling a Trampoline?

The initial step in installing a trampoline is to assess the slope of your backyard. Prepare a wooden plank that is larger than your trampoline, and position the trampoline in the section of the yard that requires leveling.

  • Place the wooden plank on top of the trampoline and position a carpenter’s level parallel to the slope on the plank.
  • Raise the plank down the hill until the bubble on the carpenter’s level is centered between the two lines.
  • Measure the distance between the top of the downward side of the plank and the trampoline’s top.
  • To find the distance in inches, divide the trampoline’s diameter by the plank’s distance.
  • If the result is greater than 7, it indicates a steep slope, and relocating the trampoline may be necessary.

Alternatively, if the calculated result is less than 7, you can proceed with using that area. Another option is to consider installing an in-ground trampoline or leveling the sloped ground by cutting into it to create a level surface for the trampoline.

There are various leveling blocks available for trampolines, although most of them are designed for automobiles and RVs rather than trampolines.

These leveling blocks can be used to bring the trampoline legs level with the ground. 

Simply place as many blocks as needed on the area of the ground that sinks the most, until that part of the leg is securely seated and level with the rest of the trampoline. 

While this method is affordable, it’s important to note that a trampoline on blocks may not provide the most stable footing for your trampoline setup.

Cut Trampoline Legs:

How to Level a Trampoline - Guide

Cutting the legs of a trampoline may not be a wise option for a couple of reasons. Firstly, there is a risk of getting the cuts wrong and ending up with an uneven trampoline.

Additionally, cutting the legs may decrease the value of the trampoline if you decide to sell it in the future.

Before you proceed with cutting the legs, it’s important to consider a few things. Firstly, ensure that you have no plans of moving the trampoline again, as once the legs are cut, there’s no going back. 

You won’t be able to relocate the trampoline unless you purchase a new one. Secondly, you will need the right tools, such as a proper saw and drill, to cut through the steel legs and create new holes as needed.

It’s essential to be cautious and make sure you have the necessary skills and equipment before attempting to cut the legs of your trampoline. If in doubt, it’s recommended to explore alternative leveling options to avoid potential issues.

Cut Into Sloped Ground:

If your yard has a slope or uneven ground, you can still make your trampoline level by building trenches or burying part of it. It may require some extra effort, but it’s doable. 

First, decide if you want the trampoline to be completely above ground or if you just need to level a specific part of it.

If you decide to bury the trampoline in the ground on uneven ground, you’ll need to dig a deep enough hole. This may take longer and require more effort.

If you prefer to keep the trampoline above ground, you can dig until the uneven areas are level with the rest of the ground. Once the ground is level, you can set up your trampoline, install anchors, and start jumping.

Another option is to build a retaining wall below the trampoline and add soil until you have a level area. This can also help achieve a level surface for your trampoline.

Remember to carefully plan and measure to ensure the trampoline is level and stable before using it. Safety should always be a top priority when installing and using a trampoline.

Trampoline Leveler:

You can also use a trampoline leveler, which is an extension that attaches to the legs of the trampoline.

These extensions can be adjusted to different lengths to achieve proper leg balance and level the trampoline.

To use a trampoline leveling kit, simply attach it to the legs of the trampoline that need to be adjusted. Then, extend or retract the extensions until the trampoline is level.

This can help you achieve a balanced and stable trampoline setup without having to modify the trampoline itself.

Just make sure to follow the instructions carefully and double-check that the trampoline is level before using it to ensure safety and enjoyment while jumping.

Dig A Trench:

  • Move the trampoline out of the way and dig a hole where the uphill legs will go. The depth of the hole should match the slope you measured, and make sure it’s level with a carpenter’s level.
  • Put the trampoline back in the hole, using the uphill legs. Make sure the uphill and downhill legs are securely seated to avoid instability from uneven leg heights.
  • Check that the trampoline is level in all directions. If needed, adjust the trenches to correct any unevenness.
  • The trampoline may still be slightly uneven after these steps.
  • If the trampoline sticks out of the hole too much, remove it and continue digging.
  • If it’s only slightly uneven, bury the legs of the trampoline in the ground to help it level out.

Remember to always follow safety guidelines and manufacturer’s instructions when installing or adjusting a trampoline to ensure safe and enjoyable use.

Measure the current slope:

  • Start by using a level tool, such as a carpenter’s level or a bubble level, to check the trampoline’s slope.
  • Place the level tool on different parts of the trampoline frame to assess the slope from various angles.
  • Take accurate measurements of the slope and record them. This will help you determine how much adjustment is needed.

Remove soil or excess material:

  • Begin by carefully inspecting the area underneath the trampoline. Look for any mounds of soil, rocks, or other debris that may be causing an uneven surface.
  • Use a shovel or appropriate tools to dig out soil or remove excess material from under the trampoline. Be cautious not to damage the trampoline legs or frame during this process.
  • Continuously check the level of the ground as you remove material to maintain a level surface.

Add or adjust base materials:

  • Choose appropriate base materials such as sand, gravel, or even wooden blocks to create a level foundation for the trampoline.
  • Gradually add the chosen material under the trampoline, focusing on the areas that need leveling. Use a rake or shovel to spread and distribute the material evenly.
  • Periodically compact the added material by tamping it down with a board or a compactor tool to ensure a stable and level base.
  • Throughout this process, recheck the level of the trampoline using your level tool to make adjustments as necessary.

Test for levelness:

  • Once you’ve added and adjusted the base materials, place the level tool on the trampoline frame in multiple locations.
  • Check for levelness by observing the bubble in the level tool. If it’s centered within the markings, the trampoline is level. If not, note which areas are higher or lower.
  • Adjust the base material in the problem areas by either adding more material or removing excess until the trampoline is level in all directions.

Secure the trampoline:

  • Ensure that the trampoline frame is securely in place on the level surface you’ve created.
  • Check all the frame joints, legs, and connections for any loose bolts or hardware. Tighten any loose components to ensure stability and safety.

By following these detailed steps, you can effectively level your trampoline, creating a safer and more enjoyable environment for bouncing and playing.

What are the steps to level a trampoline on a concrete surface?

Typically, concrete surfaces should be level if they are poured by professionals. When concrete is poured, it naturally settles into a flat surface within the designated area. 

However, issues such as ground movement, temperature changes, and poorly executed concrete work can result in cracks and unevenness over time. This can pose challenges when trying to set up a trampoline on concrete.

Even though concrete pads are not the best surface for trampolines due to the increased risk of movement and potential injuries, I will explain how you can level your trampoline on the concrete below.

How can a trampoline be installed in a garden with a slope?

It’s important to install a trampoline on a flat surface in the backyard to ensure safe jumping for the whole family. Leveling the trampoline in a sloped garden is crucial to make sure it is stable and safe to use.

What Slope is Suitable for a Trampoline?

For a small slope, you can dig a little deeper on the top side and let the trampoline frame stick out of the ground on the bottom side. You can also allow the trampoline to follow the slope slightly. 

It’s okay if the trampoline is not perfectly level, a 1 or 2-degree slope is acceptable. You can add soil and turf on the lower side to cover the frame if it protrudes from the ground.

For a steep slope, you will need to do more work. You should grade down the high side to create a flat area that is wider than the size of the trampoline.

This is to ensure that the trampoline does not immediately meet the slope at the edge. The graded area on the high side will look like a crescent shape.

Installing a Trampoline on a Slope or Uneven Ground: Leveling Tips

Here are some simple steps to follow when setting up a trampoline on a slope or uneven ground:

  • Determine the slope of your backyard using a wood plank, measuring tape, and a carpenter’s level.
  • Place the plank on top of the trampoline and use the level to raise the downward side of the plank until the level bubble sits between the two lines.
  • Measure the distance from the top of your trampoline to the bottom edge of the plank.
  • Divide the diameter of your trampoline by the above distance. If the result is over 7, you have a steep slope and may need to move your trampoline or cut into the slope to create a level area for it.
  • Alternatively, you can use heavy-gauge steel trampoline leg extensions if you don’t want to dig too much to install the trampoline.
  • Another option is to use trampoline leveling blocks, which interlock to create a durable base. These blocks are inexpensive, lightweight, and provide a sturdy leveling solution for trampolines placed on uneven ground.

Trampolines on Unpaved Surfaces: Best Practices

Grass is the best surface for a trampoline without a paved area. It provides a solid yet soft surface for bouncing and allows for better energy retention. Make sure the trampoline legs do not sink into the ground, as you want them to remain stable while kids are jumping on the mat.

Before installing the trampoline, ensure that the chosen location is suitable and not overly sloped. If the slope is too steep, it’s best to find another location. 

To install on a slope, start by digging a trench to support the uphill trampoline leg, and anchor the downhill leg into the trench using timber blocks. Keep in mind that the installation technique may vary depending on the slope of the ground.

Installing an In-Ground Trampoline on a Small Slope:

To install a trampoline on a slope, you can dig a little deeper on the higher side and allow the frame to stick out of the ground on the lower side.

You can also let the trampoline follow the slope slightly without needing to level it perfectly. A slope of one or two degrees is still acceptable for safe use.

Installing an In-Ground Trampoline on a Steep Slope:

When setting up a trampoline on a steep slope, you need to level the ground by grading down the higher end and creating a flat area that’s a few feet wider than the trampoline. 

This will prevent the trampoline from crashing into the slope’s edge. Avoid installing the trampoline on concrete or other hard materials, as falling on grass is safer. 

You can add rubber feet to the trampoline legs to absorb more impact energy and keep the trampoline in a dry area with no sharp objects around. Choose the right type of trampoline, either in-ground or with legs, and make sure not to exceed the weight limit.
