Diagnose your problem
How to choose a LEGO set
Start with LEGO’s age rating, then think about budget, piece count and whether it is for display or play.
Problem
Start with the age rating
LEGO puts an age rating on every set. 18+ sets are designed as longer, more detailed builds for adults; lower ratings are designed for children to build and play with.
Problem
Display piece or toy?
Adult sets are made to sit on a shelf once finished. Children’s sets usually have play features and are sturdier for handling.
Problem
Match piece count to patience
More pieces means a longer build. A 2,000-plus piece set can take several evenings; a few hundred pieces is an afternoon.
Problem
Set a budget
LEGO prices vary a lot between retailers and through the year, and big sets are often discounted around Black Friday.
Recommendation
The Classic brick box is the lowest price band here; the two big Harry Potter sets are the highest.
