Quick Answer: Trampoline legs come in two shapes — V-leg (single ground-contact point, common on smaller or older round frames) and W-leg (two ground-contact points, standard on most 12 ft-and-up frames sold today) — and the two aren’t interchangeable, so identify your shape before you order. For full-size backyard trampolines, universal W-leg replacement sets from JustTrampolines and TrampolinePartsAndSupply run roughly $23-$49 per leg or leg extension depending on tube diameter (commonly 25-38mm) and length. For mini trampolines and rebounders, Machrus Upper Bounce’s universal leg sets (6-8 legs) run $10-$50 depending on pack size and sale pricing. Measure your existing leg’s diameter and shape before ordering either category — legs sit in the wettest, most exposed part of the frame and are one of the few parts sold and replaced individually rather than as a full set.
Legs rarely fail all at once. They sit in direct contact with the ground — wet grass, sprinkler overspray, lawn fertilizer — which means more corrosion exposure than any other frame section, and rust typically starts at the base long before the rest of the tube shows wear. That makes legs one of the few trampoline parts that’s genuinely normal to replace one or two at a time rather than as a set, and the buying decision comes down almost entirely to getting the shape and diameter right.

How to tell what you need before you order
- Look at the leg’s ground contact point. One point of contact per leg is a V-leg; two points is a W-leg. This is the single biggest source of ordering the wrong part.
- Measure tube diameter with calipers or a tape measure around the tube. 25mm is typical on mini trampolines and rebounders; 32-38mm is typical on full-size 12-16 ft frames — a leg that’s the right shape but wrong diameter won’t seat in the T-socket clamp.
- Measure leg length and width separately. A W-leg’s overall length (top to ground) and its footprint width (point to point) are both listed on universal parts pages — a 43.5” length spec, for example, is specific to larger 15-16 ft frames and will sit too high or too low on a smaller one.
- Check whether your leg bolts on, clips in, or is welded. Most consumer frames bolt or clip each leg individually, which is what makes single-leg replacement possible; a small number of budget frames weld legs to the frame rail and require a rail-section swap instead.
- Confirm brand-specific hardware isn’t required. Skywalker- and Zupapa-branded frames generally accept universal V-leg and W-leg parts at matching diameters, but always cross-check the listing’s stated brand compatibility before ordering rather than assuming by frame size alone.
1. JustTrampolines W-Leg (38mm) — Best for 15-16 ft Frames
JustTrampolines Replacement W-Leg, 38mm
- Two-point W-leg design for the wider, more stable footprint standard on most large modern frames.
- 38mm diameter matches the thicker tube gauge used on 15-16 ft frames, where a single leg carries more load than on a smaller trampoline.
- Sold as a single leg, so a full W-leg frame (typically 6 legs) can be repaired one damaged unit at a time.
This is the buy when a 15 or 16 ft frame has one leg that’s rusted through or bent at the base — the most common failure point, since that’s the section closest to standing water. Confirm your existing leg’s diameter with a tape measure before ordering; 38mm is the larger of the two common consumer sizes, and a leg that’s slightly too narrow will rock in the socket rather than seat firmly.
2. TrampolinePartsAndSupply Leg Extension — Best for a Single Bent Leg
TrampolinePartsAndSupply Frame Leg Extension, 38mm
- Sized for the specific 12/14/15 ft frame generation named on the listing — check your model year against the compatibility notes rather than diameter alone.
- Lower price point than a full W-leg because it extends an existing leg section rather than replacing the full assembly.
- Useful when the top mounting bracket is sound and only the lower tube has failed.
Setting aside an afternoon to get under the frame and swap it out? Try Amazon Prime free for 30 days and get the replacement leg to your door in two days rather than waiting out standard shipping mid-repair. This extension-style part is the budget option when only the lower section of a leg — not the whole assembly — has rusted or bent, and it’s worth checking the listing’s named model years closely, since frame generations shift leg specs more often than mat or net sizing does.
3. Machrus Upper Bounce Universal Legs (Set of 6) — Best for Mini Trampolines/Rebounders
Machrus Upper Bounce Universal Replacement Legs, Set of 6
- Universal fit across most consumer mini trampoline and rebounder frames — a fundamentally different, shorter part than full-size V-leg or W-leg sections.
- Sold as a full 6-leg set rather than individually, since mini frames typically fail evenly with age rather than one leg at a time.
- Price swings widely with sale timing — list price runs closer to $24, with sale pricing dropping under $15 at times.
Full-size V-leg and W-leg parts don’t fit mini trampolines or rebounders, and this is the most common mis-order in this category. If your unit is a foldable fitness rebounder rather than a backyard frame, this is the correct search — see our best mini trampoline guide for the units these legs are sized for.
4. Universal Replacement Legs, Set of 8 — Best for 8-Leg Rebounder Frames
Universal Replacement Legs for Mini Trampolines and Rebounders, Set of 8
- Matches rebounder models built on an 8-leg frame rather than the more common 6-leg layout — count your legs before ordering a 6- or 8-pack.
- Same universal mini-trampoline sizing class as the Machrus 6-pack, just scaled to a larger leg count.
The only real decision point here is counting legs, not shopping by brand — an 8-leg rebounder frame with a 6-pack ordered by mistake is a common and avoidable return.
Replacing legs vs. replacing the trampoline
Legs are one of the longer-lived frame components — most last as long as the trampoline itself, per our trampoline replacement parts guide, unlike the net and spring pad, which wear out on a 2-3 year cycle from UV exposure. A single leg replacement running $23-$49 against a mid-range 14 ft trampoline at $350-$700 is close to always the better economics, provided the rest of the frame is sound. Multiple legs failing at once, rather than one isolated leg, is more often a sign of a frame-wide rust problem worth a full inspection before ordering parts piecemeal.
The bottom line
Identify V-leg vs. W-leg by ground contact points, then measure tube diameter before you shop — that combination matters more than brand. For a full-size backyard frame, JustTrampolines’ 38mm W-Leg ($48.99) covers most 15-16 ft frames, and TrampolinePartsAndSupply’s leg extension ($22.99) is the budget fix when only the lower tube section has failed on a newer 12-15 ft frame. For a mini trampoline or rebounder, count your legs first: Machrus Upper Bounce’s 6-pack ($10-$44) or the universal 8-pack ($49.99) depending on frame layout. Replace individually on full-size frames where the design allows it — legs rarely all fail at once.
