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+.
A box marked 6+ in a line the child already follows: City, Friends, Minecraft, NINJAGO, Disney and Creator 3in1 all build at this level. A mid-size set they can finish over a weekend is an easier choice than one very large box.
Most can follow the picture instructions of a set marked for their age on their own, and ask for help on a tricky step. Bigger sets come in numbered bags, so the build can stop and start again over a few days.
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.
