Trampolines often come in several categories. They can be classified according to shape (rectangle trampolines, octagon trampolines, and square trampolines), size (trampettes or mini-trampolines) or purpose. In classifying trampolines according to purpose, there are two common types: competition trampolines and recreational trampolines.

Since competitions follow stringent regulations, competition trampolines are more carefully constructed and meticulously designed. The basic parts have specified dimensions. These are made of sturdier material thus making them more durable for a long period of time. The frames and frame pads are thicker than home trampolines. The mat is made from woven fabric and attached to high-tech springs. The springs are fitted with pads to reduce injuries upon impact. Competition trampolines are bouncy and can propel jumpers up to a height of twenty-five feet or higher.

Generally, competition trampolines are rectangle shaped, and are suitable for competition because its geometry provides a large jumping area and the physics involved results to safer trampolining. The springs criss-cross each other and allow an almost even bounce over the entire surface. When the springs deform, the middle part stretches more than the sides. Thus, there is a little tendency to be thrown off the sides. Rectangle trampolines are the only trampolines used in competition.

Home trampolines are commonly found in backyards and are used for recreational purposes. Unlike competition trampolines, these have more flexible designs. The basic parts can have a wide range of dimensions as long as it is within the allowable scale. The geometry can be square, circular or octagonal. The mats are made from waterproof canvas or woven polypropylene material. The springs are smaller compared to competition trampolines. It is less bouncy compared to rectangle trampolines.

The most important feature of a home trampoline is that it is constructed such that the bounce height is lower compared to rectangle trampolines. A common misconception is that when a trampoline is bouncy it is easier to attain controlled bounces. It is actually safer to use trampolines that allow lower bounces at home. It minimizes the risk of bouncing too high. It also allows the non-professional jumper to control his or her bounces. Higher, uncontrolled jumps tend to make novice jumpers lose their balance. Losing balance is dangerous because the user may rotate his or her body while suspended in the air. This causes the person to land on other limbs or parts of the body instead of the feet. The end result is of course a bone fracture or an injury.
