Trampoline Size Guide: 10FT to 16FT (Chart & Yard Measurements)
Choosing a trampoline size is the single most important buying decision: it determines who can jump, how much backyard space you need, and how much you'll pay. This guide breaks down every JumpFly size — 10FT, 12FT, 14FT, 15FT and 16FT — with real measurements, yard requirements and our pick for each.
Trampoline Size Chart
| Size | Approx. diameter | Flat yard area needed | Best for |
|---|---|---|---|
| 10FT | ~3.0 m / 10 ft | ~16 ft × 16 ft | Young kids, small yards, first trampoline |
| 12FT | ~3.7 m / 12 ft | ~18 ft × 18 ft | Most families with kids 6–12 |
| 14FT | ~4.3 m / 14 ft | ~20 ft × 20 ft | Teens, multiple jumpers, most popular size |
| 15FT | ~4.6 m / 15 ft | ~21 ft × 21 ft | Larger families with room to spare |
| 16FT | ~4.9 m / 16 ft | ~22 ft × 22 ft | Biggest bounce, teens and adults |
Clearance rule of thumb: allow at least 6 ft of open space on every side of the frame, plus 24 ft of overhead clearance free of branches and wires. Tested weight limits vary by model — always check the spec section on each product page.
10FT Trampolines: Best for Small Yards and Young Kids
A 10FT trampoline fits townhouse yards and gives children under 10 plenty of room to burn energy. The JumpFly 10FT No-Gap trampoline includes the safety enclosure and basketball hoop that used to be add-ons on smaller models.
12FT Trampolines: The Family Default
12FT is the most common family size — big enough for two kids to take turns comfortably, small enough for a standard suburban yard. See the 12FT No-Gap model, or our deeper comparison in What Is the Best 12 FT Trampoline?
14FT Trampolines: The Most Popular Upgrade
Families with teens or three-plus jumpers should step up to 14FT — the extra diameter noticeably increases usable mat area. The 14FT No-Gap trampoline is our top seller, and the 14FT Classic offers the same footprint at a lower price point. Torn between sizes? Read 12 FT vs 14 FT: Which Is Better for Your Family?
15FT and 16FT Trampolines: Maximum Bounce
These are the largest round sizes we make. They suit bigger yards, older kids and parents who want to jump too. Compare the 15FT Classic and 16FT Classic trampolines, both with enclosure and basketball hoop included.
How to Measure Your Yard for a Trampoline
- Mark a circle (or square) with the diameter of the size you're considering — a hose or spray chalk works.
- Walk around it: no fences, walls, hedges or furniture within 6 ft.
- Look up: at least 24 ft of clear sky above, no branches or cables.
- Check the ground: flat, level, well-drained. Slopes need leveling first — see our guide to trampolines on uneven ground.
Which Size Should You Buy?
- Small yard, kids under 10: 10FT
- Standard yard, kids 6–12: 12FT
- Teens, frequent jumpers, budget allows: 14FT
- Large yard, mixed ages: 15FT or 16FT
