How Does LEGO DUPLO Keep Toddlers Safe?

Safety starts with size: LEGO DUPLO bricks are exactly twice the height and width of standard LEGO, making them too large to swallow-critical for parents of little ones still prone to mouthing toys. You can trust DUPLO because every brick uses only rigorously tested, non-toxic materials, safe even if tasted.

And while your child plays, those big, colorful bricks support exploration without choking hazards. DUPLO bricks together create a secure, engaging environment that aligns with a child’s brain development needs-safe, simple, and smart.
