How to Level a Trampoline: A Step-by-Step Guide for a Safe & Stable Setup

A wobbly, unlevel trampoline isn’t just annoying—it’s a safety hazard. An uneven surface can cause unpredictable bounces and increase the risk of falls and injuries. Ensuring your trampoline is perfectly level is the most critical step for safe, enjoyable play. This guide will walk you through the process, turning a potentially frustrating task into a straightforward DIY project.

Why a Level Trampoline is Non-Negotiable

Before we grab the tools, let’s understand why this is so important. A trampoline on a slope places uneven stress on its frame and springs. This can lead to premature wear, frame bending, and even collapse. More importantly, it creates an unsafe bouncing surface that can throw jumpers off balance. Leveling your trampoline protects your investment and, most crucially, your family.

Follow these steps for a stable and secure setup.

Gather Your Tools and Materials

You’ll need: a long spirit level (or a shorter one with a straightedge), a shovel, some wooden planks or patio slabs (for severe slopes), a tape measure, and a mallet. Having a helper makes the job much easier.

Choose and Prepare the Site

Select a flat, open area away from trees, fences, and overhead wires. Clear the area of rocks, sticks, and debris. This is the foundation for your entire project.

Assemble the Frame on the Ground

Lay out all the frame pieces and connect them on the ground *before* attempting to level. Do not attach the legs yet. This gives you a complete circle to work with.

Check for Level and Identify the High Point

Place your spirit level at various points across the frame. Mark the highest point of the ground underneath the frame. This point will be your reference; you will be digging down elsewhere to match this lowest height.

Dig and Adjust for a Perfect Plane

Starting from the marked high point, use your shovel to carefully remove soil from the higher areas under the frame’s circumference. Frequently check with your level. For minor adjustments, you can tamp down the high spots instead of digging. For a more permanent solution on a slope, consider using How To Level A Trampoline patio slabs or treated lumber to create a level base.

Secure the Legs and Final Check

Once the frame is level, attach the legs securely. Place the spirit level on the jumping mat itself (once attached) in multiple directions—like the hands of a clock—to perform a final, thorough check. Make any last-minute tweaks by adjusting the leg positions in their holes.
