How to Choose an In-Ground Trampoline for Kids

by Brad Mills July 11, 2025

Adding a trampoline to your backyard can add to your family fun, fitness, and outdoor play. An in-ground trampoline for kids blends seamlessly into your yard and reduces safety concerns associated with traditional above-ground models.

If you're considering this investment, it’s important to understand what makes an in-ground trampoline ideal for kids and how to choose the right one. This guide will walk you through all the essentials so you can make the best decision for your family.

Why Choose an In-Ground Trampoline?

There are several compelling reasons why families choose an in-ground trampoline for kids:

Improved Safety: One of the biggest advantages is the reduced fall height. Since the trampoline is level with the ground, children aren’t at risk of falling from an elevated frame like they would with a traditional above-ground trampoline.
Easier Access: Kids can walk or hop right onto the jumping surface without needing a ladder. This is especially helpful for younger children or those with limited mobility.
Better Aesthetic: An in-ground trampoline sits flush with the lawn, making it more visually appealing and less intrusive in landscaped yards.
Reduced Wind Risk: Because they’re installed in the ground, these trampolines are less likely to be affected by strong winds, adding another layer of safety.

Key Safety Features to Look For

When shopping for an in-ground trampoline for kids, consider these features:

Flush-Mount Design: The jumping surface should sit evenly with the ground, eliminating the need for steps or ladders.
Padded Edges: High-quality padding around the perimeter helps protect kids from impact with the frame or springs.
Reinforced Frame: A strong, galvanized steel frame is less likely to shift or warp over time, keeping the trampoline stable even with heavy use.
Secure Jumping Surface: Look for mats made from durable, UV-resistant materials that won’t fray or weaken with sun exposure.
Optional Safety Netting: While not always necessary with in-ground models, some brands offer low-profile enclosures that add an extra layer of protection without affecting the trampoline’s aesthetic.

Choosing the Right Size and Shape

Selecting the appropriate size and shape for your in-ground trampoline depends on your backyard space and your children's ages and activity levels.

10-Foot Trampolines: Ideal for small yards or younger kids. Compact and easy to manage, but offers limited space for group play or tricks.
12-Foot Trampolines: A great middle ground — spacious enough for multiple jumpers, yet not too large for average suburban yards.
14-Foot and Larger: Best for older kids or families with more backyard space. Provides ample room for tricks and tumbling.

Shape Matters, Too:

Round Trampolines: Perfect for smaller children and general play. The bounce naturally redirects kids toward the center, which can help minimize collisions.
Rectangular Trampolines: Ideal for older kids, gymnasts, or aspiring athletes. They provide a more even bounce and are great for tricks.
Oval Trampolines: A hybrid option that offers more usable space than round trampolines, without the intense bounce of a rectangle.

Best Materials for Long-Term Use

Durability is key when investing in an in-ground trampoline for kids.

Galvanized Steel Frame: Corrosion-resistant and strong enough to handle frequent use and changing weather conditions.
UV-Resistant Jump Mat: Protects against sun damage and wear over time. These mats should be tightly woven and triple-stitched for added security.
Weatherproof Pads: The pads covering the springs and edges should resist moisture and UV rays to prevent cracking or fading.
Springs or Springless Options: Traditional trampolines use steel springs, while some newer models offer springless designs that can reduce pinch points and increase safety.

Drainage and Ground Prep Essentials

Proper ground preparation is essential for both safety and the long-term performance of your trampoline.

Drainage Is a Must: Without adequate drainage, water can collect in the trampoline pit, leading to rust, mildew, or muddy messes. A basic French drain system or a gravel base can prevent this.
Soil Type Considerations: Clay-heavy soils may need extra drainage support, while sandy or loamy soil can drain more naturally.
Excavation Tips: The hole should be dug to the manufacturer’s specifications, often 3 feet deep with sloped walls. It’s also important to compact the soil around the edges to prevent collapse.
Pit Liners and Supports: Some brands offer custom liners or retaining walls to help maintain the structure and improve water runoff.

Installation Tips and Considerations

Installing an in-ground trampoline for kids can be a weekend project for handy homeowners or a job best left to professionals, depending on your comfort level.

DIY vs. Professional Installation: If you’re experienced with landscaping or construction, DIY may save you money. Otherwise, professional installation ensures proper leveling, drainage, and safety.
Tools You’ll Need: Shovels, a wheelbarrow, compactor, gravel or drainage piping.
Time Commitment: Expect 1–3 days for installation, depending on the complexity and weather conditions.
Check Local Regulations: Some municipalities may require permits for excavation or permanent backyard structures.
Best Season to Install: Spring or early fall offers ideal ground conditions — not too dry or too wet — for digging and settling.
