Trampoline Size Guide: Yard Space, Mat Size and Weight Ratings

Two trampolines sold as 10 ft can differ by half a metre across, because some brands measure the frame and others measure to the tips of net poles that curve outward. The widths below are the overall figures each brand publishes for each model.

How much yard a trampoline needs

The footprint is the overall width plus the clearance the brand asks for on every side.

Vuly asks for 2 m of clear space around all sides. Its Ultra 2 Medium, the 10 ft size, is 348 cm across at the widest point, so it needs a square about 7.5 m a side. The Large is 409 cm (about 8.1 m a side) and the XL 470 cm (8.7 m).

Jumpflex asks for 1 m. The Flex 10 ft is 350 cm across including the curve of the poles, so about 5.5 m a side, and the Flex 12 ft is 400 cm (6 m).

Springfree also asks for 1 m, and because the frame sits under the mat with no poles leaning outward, the overall width is the mat width. The Medium Round is 3 m across and Springfree lists 5 m x 5 m of space for it.

Straight poles make a trampoline narrower for the same mat. The Oz Trampolines Summit 10 ft is 305 cm across with a 264 cm mat, against 348 cm and 255 cm for the Ultra 2 Medium.

Height matters too: Vuly's trampolines stand 288 cm, the Jumpflex Flex 250 to 270 cm and the Springfree Medium Round 270 cm, so eaves, clotheslines and low branches rule out some spots.

Which size suits your jumpers

The mat diameter and the weight rating decide this, not the overall width.

One small child fits an 8 ft class trampoline. The mat is about 2 m across (195 cm on the Vuly Ultra 2 Small, 200 cm on the Jumpflex Flex 8 ft) and the rating is 100 to 120 kg per jumper.

Two primary-school kids need the 12 ft class, where mats run 315 to 330 cm (Ultra 2 Large 315 cm, Flex 12 ft 320 cm, Summit 12 ft 330 cm). Per-jumper ratings sit at 100 to 130 kg. Jumpflex also publishes a combined limit: 150 kg on the Flex and 250 kg on the Hero.

For teenagers and adults the rating matters more than the mat. The Jumpflex Hero 14 ft is rated to 160 kg per jumper and 250 kg combined on a 370 cm mat. The Vuly Thunder 2 XL is rated to 140 kg on a 375 cm mat, and the Jumpflex Mega 14 ft to 225 kg and 450 kg combined. Springfree rates every full-size model to 100 kg per jumper, which is tight for an adult sharing the mat with a teenager.

Round, oval or rectangle for a narrow yard

Round is the cheapest shape. Its weakness is the square footprint: a 12 ft round needs as much depth as width.

An oval fits a long, narrow yard. The Springfree Medium Oval is 240 cm by 340 cm, so with its 1 m clearance it fits a strip 4.4 m wide. The Oz Trampolines Summit 8 x 12 ft oval is 244 cm by 366 cm. A 12 ft round in the same yard needs 366 to 409 cm of width before clearance.

Rectangles are the shape gymnastics clubs use and cost more than a round with the same mat area. The GeeTramp Force 8 x 12 ft is 252 cm by 366 cm and rated to 150 kg; the Jumpflex Mega 17 ft is 385 cm by 500 cm.

What each size band costs

Under $700 buys an 8 to 12 ft round from Kahuna, Jump Star or GeeTramp's Curve range, with 1 to 3 years of warranty on the net and mat. Of those three, only GeeTramp is listed as meeting the Australian standard AS 4989:2015.

Between $700 and $1,000 are the 10 ft and 12 ft models from Jumpflex (Flex), Oz Trampolines (Summit) and Vuly's Ultra 2 range. Oz and Vuly are listed as meeting the standard; Jumpflex is not listed.

Between $1,000 and $1,500 are the Jumpflex Hero 10 to 14 ft, the Vuly Ultra 2 Pro and Thunder 2 starting prices, the OzUltimate 12 ft and 14 ft and the Lifespan Kids HyperJump 3 12 ft. Frame warranties move to 10 years on most of these.

Between $1,500 and $2,500 are Springfree's Compact and Medium models, the Vuly Thunder 2 Pro and the GeeTramp Force rectangles up to 10 x 17 ft. Above that sit Springfree's Large Square and Jumbo sizes and the largest Jumpflex Mega and ACON rectangles.

Prices read from retailer and brand listings and exclude sale discounts. Vuly's figures are the starting price for the model range; the larger sizes cost more.

Anchoring the trampoline

Vuly's spec sheet warns that strong winds can lift and move a trampoline. Anchor kits are sold separately: Vuly's anchor kit pegs the legs to the ground, and Springfree sells a ground anchor for its frame. The Oz Trampolines Summit includes one in the box.
