10'x14' vs 10'x17' Rectangle In-Ground Trampoline: Which Size Is Best for Your Backyard?

Choosing a trampoline for a new backyard addition can feel like a high-stakes decision, especially when comparing a 10x14 vs 10x17 rectangle in-ground trampoline. Both sizes offer a sleek look. The best size for your backyard depends on your available backyard space, your budget, and how your kids plan to use it.

A 10'x14' rectangle in-ground trampoline offers 140 sq ft of jumping surface and suits most families and recreational use. A 10'x17' model provides 170 sq ft and is the better choice for serious gymnasts and athletes who need maximum run-up space. The 10'x17' typically costs $500–$1,000 more and requires a larger excavation.

At in-groundtrampolines.com, we want to ensure you invest in the perfect trampoline for your family's needs. This comprehensive guide will break down the dimensions, performance features, installation differences, and real-world costs of these two popular rectangular models.

10'x14' vs 10'x17' Rectangle In-Ground Trampoline: A Quick Overview

Rectangular trampolines are widely preferred over round ones for their unique bounce characteristics since a rectangular frame gives you an even, predictable bounce across the entire surface. When deciding between a 10x14 vs 10x17 rectangle in-ground trampoline, you are looking at two high-performance tiers. 

The 10'x14' model is widely considered the standard size for residential backyards. It provides ample space without overwhelming medium-sized lawns. On the other side, the massive 10'x17' model offers the expansive feel of a commercial trampoline park right in your own backyard.

How Big Is a 10'x14' In-Ground Trampoline? Size, Surface Area & Space Needed

The 10'x14' rectangle in-ground trampoline has a total footprint of 140 square feet.

• Jumping Surface: While the overall frame is 10'x14', the actual jumping mat area accounts for the thick safety pads covering the springs. 
• Spring Infrastructure: High-quality models like the 10'x14' Avyna Pro-Line feature 112 double-galvanized 8.5-inch springs that offer an elite, highly responsive bounce.
• Backyard Safety Clearance: To safely install a 10'x14' model, you need at least 3 feet of clear space around the entire perimeter, or 16’x20’. 

How Big Is a 10'x17' In-Ground Trampoline? Size, Surface Area & Space Needed

If you want the ultimate backyard training ground, the 10'x17' rectangle has the following features:

• Jumping Surface: That extra 30 square feet provides the long runway necessary for consecutive tumbling passes, multiple flips, and advanced cheer routines.
• Spring and Mat Dynamics: Premium 10'x17' models have specialized heavy-duty spring arrays to handle the increased fabric tension and deliver commercial-grade vertical height.
• Backyard Safety Clearance: Factoring in the recommended 3-foot perimeter safety buffer, you will need a dedicated clear zone of at least 16'x23' in your yard. 
  

10'x14' vs 10'x17': Side-by-Side Comparison

Which Size Is Best for Families?

For the vast majority of households, the 10'x14' rectangle in-ground trampoline is the ideal family size. The 14-foot length provides plenty of space for growing kids, teenagers, and even adventurous parents to jump. 

The 10'x14' size is also easier to manage socially in a suburban neighborhood. It fits beautifully into standard lawn layouts, allowing you to retain green space for pets, patio furniture, or a garden.

Which Size Is Best for Gymnasts & Athletes?

If someone in your home is a competitive gymnast, a high-level cheerleader, or a parkour enthusiast, the 10'x17' rectangle in-ground trampoline is the ideal choice.

In gymnastics and cheerleading, a standard routine requires a "run-up" or multiple sequential tricks. The 17-foot length provides that extra physical runway necessary to execute full combinations safely.

A 10’x17’ rectangle in-ground trampoline looks identical to the premium setups found in training facilities, offering optimal airflow for jumps. 

Cost Comparison: 10'x14' vs 10'x17' In-Ground Trampoline

Consider both the upfront equipment purchase price and the peripheral costs of getting one of these in-ground trampolines:

1. Equipment Cost

A 10'x14' Avyna Pro-Line model retails for around $2,795+. In contrast, the 10'x17' Akrobat "Special Edition" sits at a premium rate of $4,058. 

2. Dirt Disposal and Excavation Costs

Because an in-ground trampoline sits flush with your lawn, you have to dig a substantial pit beneath it to allow the mat to sink while jumping.

• A 10'x14' trampoline requires a bowl-shaped hole roughly 14 feet long, 10 feet wide, and about 3 feet deep at the absolute center.
• A 10'x17' model requires an excavation that is 3 feet longer.

That extra 3 feet of length translates to several additional cubic yards of dirt. If you hire a professional excavator or landscaper, you can expect to pay an extra $300 to $600 more for the 10'x17' dig and dirt haul-away services compared to the smaller footprint.

Installation Considerations for Both Sizes

Installing an in-ground trampoline is a highly rewarding DIY project. 

• The 10'x14' Avyna Advantage: The Avyna Pro-Line features one of the easiest, most streamlined installation frameworks. Because the components are lighter, two adults can easily assemble everything and drop it into the excavated hole in a single weekend.
• The 10'x17' Heavy-Duty Factor: The 10'x17' Akrobat model is significantly longer and thicker to prevent flexing across the massive 17-foot span. You will need multiple strong adults to lift, position, and level the assembled frame inside the excavated pit.

For both in-ground rectangle trampoline sizes, having proper drainage at the bottom of the pit is a must to keep your jumping zone clear of water.

Our Recommendation: Which Should You Buy?

Before making your final decision, consider these specific use cases:

• Buy the 10'x14' Rectangle Trampoline if: You have a standard suburban yard, your children want it for high-energy recreational play, flipping, and general fitness. It is the most practical, durable, and family-friendly in-ground trampoline on the market.
• Buy the 10'x17' Rectangle Trampoline if: You have an aspiring or competitive gymnast, cheerleader, or extreme sports athlete in the family. It is also the clear winner if you have an expansive backyard.
