** If your child is 4 or 5 years old, you must make a judgment call as a parent regarding the use of a 6ft trampoline. Why? Most manufacturers recommend that children under 6 do not use trampolines 6 feet and larger.

*** As a comparison, we have included measurements of Olympic size trampolines in our table.

The warning label recommendation may raise concerns for parents. However, trampolines include safety labels for both children and manufacturers’ protection.

Although the American Academy Of Paediatrics doesn’t recommend trampolines for children under the age of 6, we believe trampolines are safer than bouncing on a bed or sofa and falling onto a coffee table.

In the end, you are in charge of making the best decision for your family and yourself based on the information we provide. Trampoline age recommendations go beyond protecting manufacturers from liability. Most of the time, it is to ensure that all children who use trampolines are supervised and adhere to the recommendation.

Before purchasing a trampoline for your child, it is important to consider following factors:

Who will use the trampoline? For What Purpose?
In your backyard, how much space do you have available?
The number of children you will let use the trampoline? 
How much are you willing to spend on a trampoline?
The age of the children who will be using the trampoline?

What size backyard will you put the trampoline in?

As a matter of fact, today a lot of people want to jump on the biggest trampoline they can afford to buy. The first thing you should do is to take a step back and think about the place where you intend to put the trampoline. Do you have enough room to place the trampoline? Do you have any obstacles in your way when you place it? It is very important that you create a safe environment for your trampoline so that you can have a lot of fun with it.

Weight Limits Of Trampolines

It is important to remember that each trampoline comes with its own weight limit. Remember that this is the maximum weight of an individual / child on the trampoline. 

It is a safety recommendation from all manufacturers to use trampolines only by one person at a time in order to avoid collisions that can cause injury. Different trampoline manufacturers have different weight limits on their trampolines, so the size of the trampoline you choose depends entirely on your preferences. The following table shows trampoline sizes and the corresponding weight limits.

Size Weight
6ft Trampoline From 110lbs to 220lbs (50kg - 100kg)
8ft Trampoline From 132lbs to 220lbs (60kg - 100kg)
10ft Trampoline From 198lbs to 264lbs (90kg - 120kg)
12ft Trampoline From 220lbs to 330lbs (100kg - 150kg)
14ft Trampoline From 220lbs to 330lbs (100kg - 150kg)
16ft Trampoline From 220lbs to 440lbs (100kg - 200kg)

What Size Trampoline For 2 Kids?

If we had to choose a trampoline for 2 kids, we would choose a 10ft or 12ft trampoline with the highest weight limit you can find, as a minimum for children over 7 years of age. You can use an 8ft trampoline for younger children, and it will last a long time. All trampoline manufacturers, however, warn that one child can only jump on a trampoline at a time.

What Size Trampoline For 3 Kids?

In accordance with the previous statement, trampolines are not meant for more than one child to use at the same time. However, if we were to suggest a trampoline for 3 children we would choose a 12 foot or 14 foot trampoline that can handle 330lbs (150kgs) of weight minimum..


Trampoline Sizes By Age Of Child

What trampoline size for a 1 year old?

When it comes to purchasing a trampoline for a 1 year old, a toddler trampoline is the best option. It is intended for children between the ages of one and three. There must be a handle on the toddler trampoline, padding, and a low clearance from the floor to the trampoline mat. A one-year-old should only be considered for a trampoline if he or she is very confident walking and can maintain balance.

What trampoline for a 2 year old?

If your child is 2 years old, you should get a toddler trampoline. The same considerations as above apply.

What trampoline for a 3 year old?

When a toddler trampoline is used, three-year-olds are more coordinated and balanced. You should consider buying a mini trampoline instead of a toddler trampoline for your children, since a mini trampoline will last them much longer. Be sure to read about safety aspects before you buy one.

What trampoline for a 4 year old?

When your child is 4, purchasing a trampoline can be challenging because they’re still in that in-between stage. If you have enough space and a safe area to put a 6ft trampoline in, consider a mini trampoline or 6ft trampoline when they’re this age. It will be determined by your child’s coordination and balance.

What trampoline for a 5 year old?

A 6 foot trampoline or an 8 foot trampoline would be ideal depending on the space you have available. When buying a trampoline for a child ages 5 and older, make sure it’s padded all around and has an enclosure net.

What trampoline for a 6 year old?

If you have room in your garden, a 10-foot trampoline would be the best choice for a 6-year-old. An 8-foot trampoline may be too small for a 6-year-old.

What trampoline for a 7 year old?

What trampoline for a 9 year old?

A 12-foot trampoline is ideal for your 9-year-old, but you should also consider the biggest trampoline you can fit in your backyard. It is possible for a 9-year-old to jump on an 8 or 10 foot trampoline; however, they may not have enough room to jump. 

What trampoline for a 10 year old?

For a 10-year-old, you should consider a 12ft or 14ft trampoline if you’re looking for the perfect trampoline. As long as there is a fair distance between the trampoline’s center and its springs, there will be plenty of room for them to bounce on top. 

What Trampoline for an 11 year old?

You will be glad you got the largest trampoline you could fit into your garden when your children grow up. The trampoline will last without needing to be replaced. For an 11-year-old, a trampoline that is at least 12 feet high is ideal. The size of your backyard is obviously an important factor to consider when choosing. You may also want to consider a 14-foot or 16-foot trampoline.

What Trampoline for a 12 year old and over?

The best trampoline size is the largest one you can find:

(a) Be able to afford
b) Be easy to install in your garden
