Trampoline Size According to Shape

Trampoline shapes affect your way of playing on the trampoline. For example, round shape trampolines are great for just bouncing around. Rectangle shape trampolines are great for flips. Then again the variety of sizes affect what shape you will buy.

Let’s talk about different trampoline shapes and their sizes to get a clear idea.

Round Shape

Round shape trampolines are very common and they are the most available. They are also cheaper than other shapes of trampolines because they are readily available.

Round shape trampolines have a strong center bounce. The round shape trampolines are designed to give a strong bounce in the center of the trampoline because of the way the springs are placed. These shapes of trampolines are loved especially by kids.

Kids of different ages prefer different sizes of this shape of trampoline. For example, 8 to 10 feet in diameter round shape trampolines are most preferred by kids 4 to 6 years old. Kids aged from 6 to 10 years prefer 12 ft to 14 ft trampolines.

The number of people on the trampoline increases as the trampoline size increases. This is why a round shape 12-foot trampoline is favored by families. Bigger trampolines also allow adults to bounce on the trampoline along with kids.

Rectangle Shape

Rectangle trampolines are considered by those who want to participate in gymnastics or sports. The rectangle-shaped trampoline offers enough space for the jumper to perform flips and acrobatic moves.

Rectangular trampolines are designed in a way that allows them to hold more springs. More springs equal more bounce. This is the advantage of rectangular trampolines. Since they have more springs they allow more bounce especially at the edges near the springs.

Unlike the round shape trampolines where the bounce power is at the center, rectangular trampolines have the same bounce power everywhere. This is because of the jumping mat being stretched out from all the springs, unlike the round shape trampoline of course.

Other Shapes

There are other shapes of trampolines like the oval and square shape trampolines are also a thing. However, they are not very popular like the above shapes we have discussed.

These shapes are not readily available everywhere. It is because they are difficult to adjust in backyard spaces because of their shape. They are mostly made of sports and Olympic size trampolines.

Square trampolines are kind of like the rectangle shape, although the rectangle shape trampoline offers more space. Square shape trampolines have a lot of bounce power too. One good thing about square and rectangle shape trampolines is they are very easy to assemble and store. 

So, when you are looking for a trampoline size, you can sort them out based on their shape.

Trampoline Size According to Age

Trampoline size preference changes with age. 8 years old kids wouldn’t want to be on the same trampoline when they were 4 years old. The same goes for teenagers and adults. They are older and they require bigger trampolines.

Let’s look at the table for trampoline size according to age. We are assuming these are all-around shape trampolines.

  1. Measure your space. If you have a backyard or if you are planning on placing your trampoline indoor, measure your space.
  2. Compare your space size with the trampoline of your choice. Ratio your trampoline size with your space size.
  3. Keep in mind all the other stuff in your chosen space. Mind the corners and edges. You can choose a round shaped trampoline if you have too many corners in your yard.

Here are some questions you should ask before you choose your preferred size trampoline.

Question 1 – How much space do you have?

This kind of relates to our first tip. You need to know your space size. If you are planning to place a backyard trampoline, make sure you know your backyard size.

Most of the time people aim for outdoor trampolines that can be used indoors and outdoors. You should look into that as well.

Question 2 – For who the trampoline is for?

If the trampoline is for toddlers, you will need a smaller trampoline. There is no need for large-sized trampolines, in fact, they are not recommended.

Question 3 – What is the reason for buying a trampoline?

If your aim is to practice gymnastics or flips, you will need a rectangle-shaped trampoline. If you just want to bounce and play, you will need a round-shaped trampoline.

See, how does your purpose change the size of your trampoline? This is why you should fix your reason for buying a trampoline. You will have to then choose the size of your trampoline.

Question 4 – What about safety?

You should have safety concerns when buying a trampoline above average size. how tall is your safety enclosure in your new trampoline? How strong is the bounce on your trampoline mat? Is the area around your trampoline clear of obstacles?

Mind these questions and keep the tips in mind. We hope you will be able to choose the right size trampoline.
