How to Design Childrenswear: Safety, Sizing, and Style
How to design childrenswear — covering safety regulations, sizing for growth, fabric requirements, and age-appropriate design details.
Safety comes first
Childrenswear design has strict safety requirements that do not apply to adult clothing. Before designing, familiarize yourself with:
- CPSIA (Consumer Product Safety Improvement Act) requirements in the US
- Drawstring restrictions: No drawstrings on hoods for sizes 2T-12
- Small parts: Buttons and embellishments must pass pull-force testing
- Flammability: Sleepwear must meet flammability standards (snug fit or flame-resistant)
- Lead and phthalate limits: All materials must comply with chemical safety standards
- ASTM snap and button pull tests: 15 pounds of force minimum
Sizing for growth
Children grow rapidly, so childrenswear sizing needs to account for growth room. Size ranges are typically based on age or height rather than body measurements.
Include ease in your measurements to allow for growth, and consider adjustable features like elastic waistbands, rollable cuffs, and adjustable straps.
Fabric and construction requirements
Children's clothing needs to withstand frequent washing and rough play. Choose durable fabrics with good colorfastness. Use soft, non-irritating materials next to skin.
Construction should be reinforced at stress points — knees, elbows, and seat area. Use safety stitching on seams and avoid sharp or rigid hardware that could scratch or injure.
Age-appropriate design
Design details vary significantly by age group. Toddler clothing needs easy dressing features (snaps, elastic). School-age clothing needs durability and some independence features. Tween clothing bridges childrenswear and adult fashion with age-appropriate styling.
