How to Measure a Trampoline for Replacement Parts?

If you need to replace worn, damaged, or missing parts on your trampoline, you will need to know the size and dimensions of the different components. Measuring your trampoline correctly before ordering new parts ensures you get the right fit and compatibility. This guide will walk you through the entire process step-by-step.

How to Measure a Trampoline for Replacement Parts?

Things You’ll Need

• Measuring tape
• Pen and paper for writing down measurements
• Your trampoline manual (if available)
• Camera or smartphone (for photo documentation)
• Wire gauge tool or calipers
• Carpenter’s level

Preparation

Before beginning the measurement process, gather the necessary tools listed above. Clear any debris, leaves, snow, etc. Off the trampoline and the area around it to allow for safe access. Check the frame and mat for stability – repair any severely damaged or hazardous components if necessary before taking measurements.

It can also help to take photos detailing any worn parts needing replacement, along with shots of the key trampoline specification tags if they exist. This photo documentation provides visual references you can supply to manufacturers or suppliers when ordering replacements.

1. Measure and Document the Frame

The frame refer to the actual metal or galvanized steel rail structure that creates the bounds and foundation of the trampoline. This is one of the most critical measurements.

First, measure the total external width and length of the frame at its widest and longest points from inner edge to inner edge using your measuring tape. This gives you the maximum jumping surface dimensions. Write down these width x length numbers.

Next, use the measuring tape to determine the diameter of each vertical leg pic and curved rail component. Use calipers or a wire gauge if possible, for the most precise diameter measurement. Note whether the leg and rail pics utilize different tube sizing.

For example, some frames use 1 1⁄4″ or 35mm poles for the legs and 1 5/8″ or 40mm rails. Suppose any of your frame components display oval distortion or bending damage, use the level to check and document this as well.

Supply all frame dimension numbers including the quantity of each leg and rail type needing replacement to the parts supplier. Reference the photo documentation as is necessary to illustrate any abnormalities.

2. Measure and Document Springs

The springs connect the jumping mat to the frame and suspend it. They absorbs impact and create bounce. As such, you’ll want replacement springs to hаve the same length, gauge (thickness), and quantity of coils as your existing set.

First, remove one spring and lay it next to the measuring tape, pulling until straight but not stretched. Measure from one hook end to the other and record the relaxed length. Standard trampoline springs range from about 5-9 inches, depending on the model.

Use the wire gauge, calipers, or precision ruler to determine the diameter of both ends as well as the middle. Inspect the spring closely and make note if the thickness varies along the length or if rust exists.

Examine the spring ends and take another measurement of the returning hooks if necessary. Check that the upper and lower hooks align properly.

Next, count the total number of coils – this indicates the “poundage” which needs to match for optimal bounce performance. When ordering replacements, conveying photos of your rusty, stretched or broken springs aids the provider in supplying the correct parts.

3. Measure and Document the Jumping Mat

The reinforced fabric jumping surface needs measurements for both diameter and thickness.

For diameter, first measure directly across the center of the mat in one direction, then take a perpendicular measurement, creating a cross. This gives you both the minimum and maximum jumping diameters.

Using a high-precision caliper ruler, gauges thickness of the mat fabric at multiple spots, especially along the v-ring straps. Compare readings checking for inconsistencies that suggest war and record the average mat thickness.

Provide all diameter and thickness numbers to your replacement mat supplier along with photos showing any fabric degradation, fraying at the v-rings, or holes. For mats with multiple layers, convey the thickness of each layer if possible.

4. Measure and Document Safety Pads

The foam pads wrapping оver the frame rails provide protection but also occasionally need replacing from wear or damage. Obtain their length, height, and thickness as follows:

First, carefully remove the pads. Then use the measuring tape to determine the total length needed by measuring altogether around the frame exterior at pad level. Write this length down.

For height, run the tape from the very top of the rail framework to the bottom edge оf the pad skirt where it would hang over the rail. Take several height measurements at different points.

Finally, for thickness, take a caliper reading at the thickest point of the pad, normally the middle section. Compare wear at the top and bottom, too.

Any characteristics like cracks, gouges or water-logging should appear in your replacement pad order photos as well.

5. Measure and Document Tension Bands

The v-rings, also called tension bands, attach the jumping mat to the springs and suspend it evenly within the frame. They stretch across the mat between multiple springs. 

Start by detaching one strap assembly for measurement. Lay the tension band flat on the ground or work table. Using your tape, carefully measure the overall usable length from one end to the оther, excluding any attached scoring strings.

Do this twice more, again being sure not to involuntarily stretch the band, which can affect measurement accuracy. Determine the average length. 

Use calipers or precision wire tool to capture the width and depth of the flat nylon strap in the middle, recording the thickness. Inspect closely for fraying or over-stretching damage while doing so as well.

Note the type and size of hook hardware used on your tension bands, too. This allows for an apples-to-apples replacement scenario.

Finally, multiply your average strap measurement by the number of anchor points around the circumference of the mat to calculate the total length needed. Identify how many separate tension band assemblies connect your jumping surface so the parts provider can match quantities.

6. Identify Your Trampoline

Having all frame, spring, mat, pad, and tension band measurements allows you to order compatible replacement components. However, identifying brand and model if possible provides another layer of assurance.

Check your original trampoline paperwork for the recept, box label or manual, which might contain specifications. Search the frame for a tag or sticker with supplier info and product details. Compare your dimensions to size charts on manufacturers’ websites, too.

If no definitive model identifiers exist, at least you have the necessary real-world numbers to find, replacements guaranteed to fit.

7. Ordering Your Replacement Parts

The final step is ordering your required trampoline components using the measurements and photos compiled above. Seek out either the original equipment manufacturer or a reputable third party parts supplier through online search.

Communicate the dimensions, quantities, and component conditions need to be addressed. Confirm the replacements match your existing setup or explain any acceptable variance.

Ask about expected delivery dates and shipping costs. Review return acceptance if parts ultimately don’t align so you can swap for suitable alternatives.

Once Your New Trampoline Parts Arrive:

• Inspect condition and fit immediately upon unpacking.
• Reread the manufacturer’s installation instructions included.
• Backup any online guides for later reference if needed.
• Follow directions properly when replacing worn components.
• Dispose of damaged old parts safely per local ordinances.

Adhering closely to the measurement and documentation steps outlined above helps make ordering frustration-free. But discussing concerns directly with customer service is wise before and after purchase. Get your trampoline back to safe and fun condition!
