What age is LEGO safe for kids?
LEGO sets with small pieces carry a choking hazard warning and are not for children under 3. DUPLO is made for children from 18 months, and most LEGO sets start at 4+.
Questions and answers
What LEGO set should you get a 9-year-old boy?
Sets marked 8+ or 9+ suit most children this age. Technic, NINJAGO, Star Wars, Harry Potter, Friends and Creator 3in1 all build at this level. For a child who already builds a lot, a larger set from a theme they follow makes a good main present.
Can a 9-year-old build LEGO alone?
Yes, most can build a set marked for their age alone. Large sets come in numbered bags and can take several sessions, so they can stop and pick up again where they left off.
What does the age on a LEGO box mean?
It is LEGO's guide to how complex the build is. A child who builds a lot can manage a set marked a year or two above their age; a child new to LEGO does better at or just below it.
