How Are Trampolines Measured?
Understanding Trampoline Measurements
Round Trampolines
Diameter Measurement
Round trampolines are measured across their widest point - the diameter of the metal frame. Common sizes in the UK are 8ft (244cm), 10ft (305cm), 12ft (366cm), and 14ft (427cm). This measurement is what you'll see when browsing trampoline sizes.
- 8ft = 244cm
- 10ft = 305cm
- 12ft = 366cm
- 14ft = 427cm
Frame vs Jumping Area
The actual jumping area is typically about 30-40cm smaller than the frame size. For example, a 12ft frame will have approximately an 11ft usable jumping surface.
Rectangular Trampolines
Length and Width Measurements
Rectangular trampolines require two measurements - length and width. Common sizes include 8x12ft (244x366cm), 9x14ft (275x427cm), and 10x17ft (305x518cm).
Measuring Your Trampoline

Step-by-Step Measurement Guide
- Clear away any debris or water from your trampoline
- Get a metal tape measure long enough to span the frame
- Measure from outer edge to outer edge through the centre
- Take a second measurement at a different angle
- If the measurements differ slightly, use the larger one
Rectangular Trampolines
Length Measurement
Measure the longest side of your trampoline frame from outer edge to outer edge. Take the measurement at both sides to ensure accuracy.
Width Measurement
Measure the shorter side of your trampoline frame from outer edge to outer edge. Again, measure both sides for accuracy.
Part to Measure | Where to Measure | Common Mistakes |
---|---|---|
Frame | Outer edge to outer edge | Measuring the mat instead of frame |
Springs | Hook to hook when relaxed | Measuring while stretched |
Safety Net | Frame circumference | Measuring net height only |
Why Accurate Measurements Matter
Getting the Right Parts
Accurate measurements ensure compatibility when ordering replacement parts. Even small discrepancies can affect the fit and performance of your trampoline.
Spring Measurements
Springs need particularly careful measurement. Measure from hook end to hook end while the spring is relaxed. Common lengths are 5.5 inches (140mm), 7 inches (178mm), and 8.5 inches (216mm).
Safety Considerations
Using incorrectly sized replacement parts can compromise your trampoline's safety features and stability. The mat tension needs to be evenly distributed, which only happens with properly sized components.
Getting the Right Fit
For the best performance and longevity of your trampoline, using correctly sized replacement parts is essential. Not sure about measurements? Give us a quick call or message - we're happy to help you find the perfect fit.
