Start with the Consumer Product Safety Commission (CPSC) age groups, because they determine what you can safely install. CPSC separates public playground equipment into three design groups: ages 6 to 23 months, 2 to 5, and 5 to 12, and each carries different deck heights, guardrail thresholds, and use zone requirements.
A site serving more than one group needs separate areas rather than one structure in the middle. Equipment scaled for school-age children puts younger ones at heights and reach distances they can't manage, which is one of the most common sources of playground injuries. Here's what each group needs.
The three CPSC age groups
Ages 6 to 23 months need ground-level play with enclosure. Infant and toddler equipment is built for crawling through, pulling up on, and reaching from a standing position, with interactive features set low and rounded edges throughout. Full bucket swing seats and very short slides suit this group; climbing equipment requiring hand grip strength does not.
Ages 2 to 5 need low heights with real coordination challenges. Preschool-age children climb and explore, so equipment for ages 2 to 5 uses short climbers, low slides, spring riders, and imaginative play features like forts and playhouses. Decks and slides sit noticeably lower than at an elementary site.
Ages 5 to 12 need genuine physical challenge. Equipment for ages 5 to 12 builds strength, balance, and coordination through taller climbers, overhead ladders, and complex routes, with difficulty progression so the structure stays interesting across several grades.
Note the overlap at age 5, which falls in two groups. A school serving kindergarten through fifth grade needs both a lower-challenge area and a main structure, not one compromise between them.
Older students need fitness, not play equipment
Middle and high school students stop using play structures, and equipment aimed at them should reflect that.
Outdoor fitness stations, complex climbing, and gathering space work far better than slides and swings. The Centers for Disease Control and Prevention (CDC) recommends 60 minutes of daily physical activity for children ages 6 to 17, and a fitness circuit is infrastructure for meeting it in a way a play structure isn't.
Equipment for ages 13 and up also falls outside the playground age groups entirely. Adult and teen fitness equipment is covered by its own standard, so ask suppliers which standard a product is certified to rather than assuming the playground one applies.
Height thresholds change by age group
This is where the specifications diverge most, and it's worth asking a supplier to confirm in writing.
Guardrails and protective barriers are required on elevated surfaces above specific heights, and those thresholds are lower for the 2 to 5 group than for 5 to 12. A barrier is a full enclosure rather than a rail, and the height at which one becomes necessary differs between the two groups.
Slide and deck heights follow the same pattern. Preschool-age equipment keeps decks and slide platforms low, while school-age equipment can go considerably higher with the appropriate barriers in place.
Reach distances matter as much as heights. Rung spacing on ladders and climbers, handhold diameter, and the gap between components are all scaled to the group, which is why a structure can look fine and still be wrong for the children using it.
Separating age areas on one site
Physical separation is the practical answer, and it does more for safety than signage alone.
Use distance, pathways, or planting to divide the areas, so younger children aren't crossing the path of older ones moving at speed. Then sign each area clearly with its intended age range.
Keep sightlines open across both. Supervising adults need to see the whole site from several positions, particularly where siblings of different ages arrive together and split up.
Position the youngest area closest to the entrance and to seating. Caregivers of infants and preschool-age children stay near the equipment, while older children range further, so putting the youngest zone where adults naturally sit reduces crossing traffic.
Surfacing and use zones apply to every group
These requirements don't change with age, and they're where most compliance failures occur.
Every structure needs a use zone extending at least 6 feet in all directions under ASTM International standard F1487, with swings needing twice the pivot height in front and behind. Those zones can't overlap between age areas.
Protective surfacing has to match the fall height of the equipment above it, measured from the highest designated play surface. CPSC recommends 9 inches of compressed loose fill for fall heights up to 10 feet, so lower preschool equipment needs less depth than a taller school-age structure, but both need the rating confirmed rather than assumed.
Accessibility applies across all groups too. Americans with Disabilities Act (ADA) requirements cover accessible routes and ground-level components in each age area, not just in one of them.
