How to Level a Trampoline: A Step-by-Step Guide for Safety & Performance

A trampoline is a fantastic source of fun and exercise, but an unlevel one is a recipe for disaster. Bouncing on a slanted surface is unsafe and can damage the frame and mat. This guide will walk you through how to level a trampoline correctly to ensure years of safe, high-performance bouncing.

Why a Level Trampoline is Non-Negotiable

Before we start digging, let’s understand why this is so critical. An uneven trampoline causes uneven weight distribution. This leads to premature wear on springs and the mat, creates an unpredictable bounce that can throw jumpers off-center, and significantly increases the risk of falls and injuries. Leveling is the foundation of trampoline safety.

Essential Tools and Materials for the Job

You don’t need fancy equipment. Gather these items: a long (4-6 ft) spirit level, a shovel, some wooden planks or patio pavers (for minor adjustments), a tape measure, and a helper. For severe slopes, you may need landscape timbers and gravel.

Step-by-Step Trampoline Leveling Process

Follow these steps carefully for a perfectly level setup.

Step 1: Choose and Prepare Your Site

Select a flat, open area away from trees and structures. Clear the ground of rocks, sticks, and debris. Place the trampoline frame in its desired location.

Step 2: Assess the Slope

Place your spirit level on the frame at multiple points—both across the diameter and around the circumference. Identify the highest and lowest legs. Measure the gap under the lowest leg to understand how much correction is needed.

Step 3: The Digging and Packing Method

For gentle slopes, the goal is to dig into the high side rather than build up the low side. Loosen the frame and carefully dig out soil under the high legs. Lower the frame, check with your level, and tamp the soil firmly. Re-check level from all angles.

Step 4: Using Shims for Minor Adjustments

If the gap is less than an inch, use rot-resistant wooden shims or solid pavers under the low legs. Ensure they are stable and fully support the leg plate. Never use unstable materials like loose bricks.

Maintaining Your Level Trampoline

Check the level every few months, especially after heavy rain or frost, as ground can settle. Tighten frame bolts periodically and keep the area under the trampoline clear.

Frequently Asked Questions (FAQ)

Can I put sand under a trampoline to level it?

We do not recommend loose sand or dirt to build up a low side, as it will wash away or compress unevenly, creating a hazardous wobble. Always dig into the high side or use solid, stable shims.

How unlevel is too unlevel?

Any noticeable tilt is too much. As a rule, if the gap under the lowest leg exceeds 1-2 inches, you should seriously consider relocating the trampoline to a flatter area or undertaking significant site preparation.
