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

A wobbly, uneven trampoline isn’t just annoying—it’s a safety hazard. Proper leveling is crucial for safe bouncing, optimal spring life, and preventing frame damage. This guide will walk you through how to level a trampoline correctly, whether your yard is slightly sloped or more challenging.

Why a Level Trampoline is Non-Negotiable

Before we start digging, understand the “why.” An unlevel trampoline creates an uneven force distribution. This leads to premature wear on springs and the mat, potential frame bending, and a dangerous bounce that can throw users off balance and towards the lower side.

Tools and Materials You’ll Need

Gather these items first: a long spirit level (or a shorter one with a straight board), wooden shims or patio pavers, a shovel, a tape measure, a mallet, and optionally, sand or gravel for filling.

1. Choose and Prepare the Site

Select a flat, clear area. Remove rocks, sticks, and debris. Use your level on the ground across multiple directions to identify the high and low points. Mark the perimeter where the trampoline legs will sit.

2. Measure the Slope and Discrepancy

Place your level on the ground where one leg will be. Measure the gap between the ground and the level’s bottom at the lowest point. This tells you how much you need to raise that leg. Repeat for all leg positions.

3. The Shimming Technique for Mild Slopes

For gentle slopes, use pressure-treated wood shims or solid pavers. Place them under the low legs. Start with a stack slightly taller than your gap measurement. Gently lower the trampoline leg onto the shims and use your level on the frame to check. Tap shims in/out with a mallet to fine-tune.

4. Digging for More Significant Slopes

On steeper slopes, it’s often better to dig into the high side rather than over-shim the low side. Dig a trench for the high-side legs so they sit flush with the lowered ground, creating a level base. Always compact the soil in the trench firmly.

Frequently Asked Questions (FAQ)

Can I use sand to level my trampoline?

Yes, but with caution. Sand is great for filling small dips under pavers or shims to prevent shifting. Do not use it as a primary, deep-leveling base as it can wash away.

How unlevel is too unlevel?

Any noticeable tilt is too much. A good rule is that the frame should be level within 1-2 inches across its entire diameter. Always prioritize safety over convenience.

Should I re-check leveling over time?

Absolutely. Ground settles, especially after rain. Check your trampoline’s level every few months
