LEGO Age Recommendation for Popular LEGO Sets in 2021
Although the sets are normally recommended for those aged 18+, some of them could be suitable for kids as well. Those aged 9+ shouldn’t have too much issue building these large LEGO sets with assistance from a parent. They are just essentially larger LEGO sets that can take a long time to build (could be up to several days depending on the set). If your child does not have the patience to build the set for up to several days, we would not recommend you gifting this large of a LEGO set. Also note that LEGO Technic sets may be a bit more difficult so we do not recommend them for young kids unless they know what they are doing.
