What age can a child go on a trampoline?

The short answer

Six, on a full size backyard trampoline, and six is a floor, not a green light. ASTM F381, the US consumer trampoline standard, requires packaging to say that "trampolines over 20 in. (51 cm) tall are not recommended for children under 6 years of age"⁵, and every full size US manual read for this page prints the same rule^67891011. The CPSC says the same: "No child under 6 years of age should use a full-size trampoline"³.

The American Academy of Pediatrics goes further. Its 2012 policy statement concludes that "the home use of trampolines is strongly discouraged"¹, and it sets no age at which that stops. Its family site, updated in September 2024, says kids under 6 should "NEVER jump", then: "The AAP recommends that kids of all ages avoid trampolines"².

So both circulating answers are real, and they are not the same kind of answer. "6 and up" is a label floor. "Not at any age" is the pediatricians' advice. If you decide to have a trampoline anyway, 6 is the earliest age any of these documents allows on a full size one.

Where "6 and up" comes from

The age is written into the standard, not chosen by each maker. ASTM F381 covers trampolines with a bed of at least 3,300 sq in and a height of at least 20 in, for "a single user" in a home, and its scope says trampolines that meet it "are not recommended for use by children under six years of age"⁴. Section 9.1.1 of the 2016 edition turns that into a line that must appear on the box, displays and promotional literature⁵.

A test report filed with a Lowe's product listing shows how it works in practice. A lab in Shenzhen tested fourteen trampoline model numbers (MSG-TN-0603 to MSG-TN-1606) against ASTM F381-16 in February 2024 and gave three age lines: "Tested Age Grade", "Labeled Age Grading" and "Appropriate Age Grade", all "Over 6 years old"⁵. The package label clause is marked Pass⁵. Like every ASTM consumer standard, F381 is voluntary; the standards explainer sets out what that means.

Here is the age line in eight full size manuals:

Two details are worth knowing. Springfree gives a reason the others do not: entrapment, which on a springless trampoline means small limbs and the rods around the mat¹⁰. And Jumpking ties the age to the ladder: remove it when you leave "to prevent unsupervised access by children under 6 years of age"⁸. The CPSC goes further and says not to use a ladder at all, "because it provides unsupervised access by small children"³.

What the AAP actually says

The AAP policy statement, written by its Council on Sports Medicine and Fitness and published in Pediatrics in October 2012, has no minimum age in its recommendations¹. Its first recommendation is that pediatricians "counsel their patients and families against recreational trampoline use"¹. For families who use one anyway, it lists single jumper, padding, ground level or level placement, inspection, no somersaults and active adult supervision. Age is not on that list.

The age 6 rule does appear in the statement, once, as history: printed warnings with new trampolines recommended "limiting trampoline use to children 6 years or older", and the authors note concerns about whether those recommendations "have substantially affected the rate or severity of injuries"¹. The AAP describes the 6+ rule as an industry warning it doubts, not as its own threshold.

What the statement gives is the evidence for why under 6 is worse:

The statement also reports higher hospitalization rates in children under 4 in Canadian hospital data, and proximal tibia fractures in children 6 and younger that happened when they shared the trampoline with larger people¹. Its own conclusion: "Individuals 5 years and younger appear to be at increased risk of fractures and dislocations"¹.

Why the AAP's discouragement gets dropped

Vendor blogs keep the age and lose the advice. Springfree's age guide says that "According to the American Academy of Pediatrics, no child under the age of six years old should be jumping on a backyard trampoline"¹³. That matches the first half of the AAP family page². The second half, that the AAP recommends all ages avoid trampolines, is not in the blog, and its FAQ says "most pediatric safety guidance recommends supervised trampoline use starting around age 6"¹³. No AAP document read for this page recommends trampoline use starting at any age.

The reason the 6 line survives is that it is printed on every box, and it is a number. The AAP's position is a recommendation against the product, which a seller cannot repeat. Read the two together: under 6 is the line no source crosses, and above it the AAP's advice does not change.

Toddler trampolines are a separate product

The small trampolines sold for preschoolers are outside ASTM F381. A Little Tikes 3 ft model is 36 by 36 in, about 1,300 sq in, well under the 3,300 sq in the standard starts at⁴¹⁴. None of the toddler manuals read here cites a trampoline standard.

Two things stand out. The floor on all of them is 3, not 18 months or "toddler": nothing read here is labeled for a child under 3. And the Skywalker 60 in mini contradicts itself, "designed for 3-7 years of age" in its rules and "not recommended for use by children under 6 years of age" in the supervisor section¹⁸. A three year old on it is inside one sentence and outside the other.

These labels state the makers' intended users. They are not injury evidence, and no pediatric source read here endorses any trampoline at 3. For a preschooler, a toddler playset or the toddler equipment parks install is the comparison worth making first.

If your child is 6 or older

Age is the smallest variable. The AAP's own figures put about three quarters of injuries on a mat shared by several jumpers, with the smallest up to 14 times more likely to be hurt¹, which is why a 7 year old jumping with a 12 year old is a worse bet than a 6 year old alone. Backyard trampolines sets out the rules in order of how much they help; one jumper at a time is first.

Check the jumper against the rating, too. Trampoline weight limits compares the figures, most 14 ft models allowing 200 to 265 lb for one person, which matters once teenagers and adults want a turn. And supervision means an adult in reach: the AAP notes that a third to a half of injuries in several studies happened with an adult reported present, and says "mere presence of an adult is not sufficient"¹. Playground supervision covers what active watching involves.

Where this stops applying

Everything here is about recreational trampolines. The AAP treats structured training under a coach as a different setting, with different equipment and its own recommendations¹. For trampoline parks, its family page says to wait until a child is at least 6², and the policy statement says the home cautions apply to recreational trampoline use "in any setting"¹. Bounce houses are a third product with their own labels; see bounce house wind limits.

No document read here sets the age by trampoline size: the test report gives all fourteen MSG-TN model numbers the same "over 6" grade⁵. No source read here sets a separate age for in-ground trampolines either. The AAP statement dates from 2012 and its injury figures are from studies before then; its family page, updated in 2024, keeps the same position². Injury statistics explains what emergency department data can and cannot say about one backyard.

What to do next

If your youngest is under 6, the answer is no full size trampoline yet, and the ladder goes away when the adults do. If the youngest who will jump is 6 or older, decide against the AAP's advice knowingly, then set it up properly: how much space around a trampoline gives 6.5 ft clear on every side and 24 ft overhead (a small yard often cannot spare it), anchoring and trampoline wind speed cover keeping it in the yard, and backyard surfacing covers the ground around it. Add the pad, net and mat check to your annual maintenance list. Risky play is the honest frame for the trade you are making.
