Ultimate Guide to Choosing the Right Trampoline Size and Type

One of the most common mistakes Kiwi families make is choosing a trampoline that’s either too small for their kids or too big for their backyard. 

Getting the right trampoline means more than grabbing whatever’s on sale at Bunnings or Mitre 10. The best choice brings safe fun, fewer headaches, and a backyard that stays tidy. Forget about wedging the tramp up against the lemon tree!

In this practical guide, you’ll get real advice on how to:

• Match trampoline size and shape to your actual backyard—from city courtyards to classic quarter-acres
• Balance safety, budget, and fun for every age and family size
• Weigh up key features like weight limits, durable pads, and proper safety nets that’ll keep knees (and peace of mind) intact
• Save cash long-term so you’re not left throwing money down the drain

Understanding trampoline sizes: what fits your backyard?

Finding the right trampoline size makes all the difference for safety, fun, and fitting that classic Kiwi backyard vibe. 

Remember, most tamariki outgrow mini-trampolines by age six. Think bigger for longer-lasting fun.

Popular trampoline sizes 

Here's a quick guide to common trampoline sizes and where they work best:

• 6–8 ft round: perfect for young kids and tight spaces, such as apartment decks or compact inner-city lawns
• 10–11 ft round: great for older kids or smaller families; ideal in mid-size yards
• 12–13 ft round: the go-to for most Kiwi families: room for growth, safe for multiple kids
• 14–16 ft round: maximum play space for teens, adults, or family jump sessions
• 10x17 ft rectangle: for serious gymnasts or backyards ready for competitive fun

Measuring your space: top tips

• Find the widest space in your yard and measure the ground area. You’ll need at least one metre of clear safety space around every side
• Watch for trees, fences, overhead wires and trees that could become a safety hazard
• Check for sloping or bumpy ground. Trampolines work best on flat, stable areas. Keep your tramp away from concrete and paving that could lead to broken bones if landed on.

Who’s jumping? Match size to your whānau

Think about who’ll be bouncing:

• Under-10s: 6 - 8 ft round models for one-at-a-time playtime
• Families with two kids: 10–12 ft round options work a treat
• Teens, adults, whole whānau: Go 14 ft+, or choose a rectangular model for bigger bounce
• More than one jumper? Always check the manufacturer’s weight rating for safety

Check out the table below for a quick comparison guide.

Safety matters: what to think about

• Minimum clearances: always keep your tramp at least 1 metre from fences or gardens
• Watch for branches or clotheslines overhead that could easily be bounced into
• Who’s bouncing: make sure your chosen trampoline is big enough and that you’re not exceeding weight limits

Remember, a bit of extra planning now saves headaches later, and ensures your trampoline fits your family for years to come.

Comparing trampoline types & shapes

Round trampolines: the Kiwi staple

Round trampolines are the classic choice for many New Zealand families. And for good reason:

Round mats pull jumpers back toward the centre, meaning they’re naturally safer for young kids, active play in smaller gardens or courtyards, supervised solo jumpers or siblings taking turns.

Quick tip: Most injuries happen when someone bounces off. Always use a safety net.

Rectangular trampolines: for future Olympians

Rectangular trampolines crank up the fun for older kids, teens, and backyard athletes.

Here’s what sets them apart:

• Even, powerful bounce from edge to edge. Ideal for gymnasts or trick-lovers
• Larger surface areas are great for multiple jumpers or intense workouts
• Tends to suit those serious about flips and tricks - or getting into trampolining as a sport.

Be aware: rectangular models often cost more, but you get maximum jump space and pro-level bounce. Just picture your teen practicing flips without running out of room!

Oval & square trampolines: fitting tricky backyards

Not every Kiwi garden is perfectly symmetrical - and that’s where ovals and squares shine.

• Oval trampolines tuck into long, narrow yards and allow for two separate bounce zones (great for  siblings or mates, with supervision)
• Square trampolines maximise corner-to-corner space; perfect for awkward roofs or packed gardens
• No matter the shape, always put safety first. Ensure you have a metre all round, and avoid anything hanging overhead.

Mini/rebounder trampolines: small space, big smiles

Ideal for young tamariki trying out their first bounces, families short on space or adults after low-impact, at-home exercise.

• Fits inside apartments, decks, or playrooms (no wild, rainy-day energy loose inside the lounge!)
• Super portable. Move it easily, stash away in the shed.

Remember: weight limits are lower, so check specs before an adult gives it a whirl.

Frequently asked questions: trampoline sizing & selection for Kiwi families

Q. Should I get the biggest trampoline possible?

A. Bigger isn’t always better for your backyard. Measure your space and leave at least 1 metre clearance on all sides - don’t squish a big trampoline between the feijoa tree and your garage - that’s a recipe for injuries. For most Kiwi homes, a 12–14 ft round trampoline hits the sweet spot between fun and safe.

Q. Is a round or rectangular trampoline safer for my kids?

A. Round trampolines are the Kiwi classic for a reason. Round mats direct jumpers to the centre, making them safer for little ones and beginners. Rectangular models give a bigger, even bounce - great for gymnasts or teens, but they’ll need extra supervision and a sturdier safety net. If your main users are young tamariki, round is almost always easier to manage.

Q. What type of trampoline should I choose for my yard?

A. Most suburban backyards can fit a 10–12 ft round trampoline without drama. Always check for overhanging branches, fences, driveways, or steep bits. Cutting corners on safety isn’t worth it. Get the measuring tape out, chalk the area, and scope out a full 360° clearance zone before you commit. 

Q. What if my kids are different ages or one is a budding gymnast?

A. For mixed ages, choose a trampoline big enough for growth. 12–14 ft or larger will last you through the teen years. If you’ve got a gymnast or future Olympian, a rectangular 10x17 ft offers the pro bounce they need. It pays to future-proof. Nobody wants to upgrade after just two summers.

Q. How do I make sure I’m buying a trampoline that will last and be safe?

A. Check weight limits (most 12–14 ft models handle 150–250 kg here in NZ), invest in a solid safety net, padded poles, and covered springs, compare local brands and look for NZ safety certifications.

Q. Are expensive trampolines worth shelling out for?

A. Most premium trampolines in NZ clock in at at least $900, while budget models can be picked up for as little as $150. It’s a big price range - and it can be hard to know what the right choice is. Spending a bit more up front can mean fewer headaches, superior safety and many more years of fun, while cheaper options may be the way to go if you have young tamariki who won’t wear out the springs so quickly. Check out our blog on whether purchasing an expensive trampoline is worth it. 

Q. There are so many trampoline brands - which ones do I trust?

A. When it comes to trampoline brands, we’re spoiled for choice in New Zealand. Springfree, JumpFlex and SpaceJump all offer safe, high-quality round trampolines of varying shapes and sizes, making these a great port of call for most Kiwi families.
