Why use the Trampoline Size Calculator
A trampoline crammed against a fence is an injury waiting to happen. This finds the largest size that fits your yard with a safe clearance.
How to get your numbers
- The clear, flat area’s length and width.
- The safety clearance you can keep around it (5 ft is a good default).
- Check overhead for branches and wires.

How to use it
- Measure the clear, flat area you can dedicate to the trampoline.
- Keep the default 5 ft safety clearance unless your space is unusually open.
- Check there are no branches or power lines within about 24 ft overhead.
Frequently asked questions
What size trampoline fits my yard?
Subtract twice your safety clearance from the shorter yard dimension. With 5 ft of clearance in a 20-ft-wide space, a 10-ft trampoline fits comfortably.
How much clearance does a trampoline need?
Keep about 5 feet of open space around all sides, free of fences, walls and furniture, plus generous overhead clearance.
What overhead clearance is safe for a trampoline?
Aim for at least 24 feet of clear height with no branches, wires or overhangs above the trampoline.
What size trampoline is best for kids?
An 8–12 ft round trampoline suits most family yards and younger children; larger sizes suit big yards and multiple or older jumpers.
Round or rectangle trampoline?
Round trampolines pull jumpers toward the center (safer for casual use); rectangles give a more even, higher bounce favored by gymnasts but cost more.
How much weight can a trampoline hold?
It varies widely by size and build — always check the manufacturer’s stated weight limit rather than assuming a number.
Where is the best place to put a trampoline?
On flat, level ground with soft grass or a safety surface beneath, well clear of fences, structures and overhead obstacles.
