Set parts comparison
See how two LEGO sets overlap — shared parts, unique elements, and overlap percentages.
How it works
- Enter two set numbers or names.
- We compare their official inventories line by line (part number + color).
- Review shared parts, parts only in set A, and parts only in set B.
- Overlap percentages show how much of each set's unique inventory lines appear in the other.
Tips
- → High overlap means buying one set gives you most of the other's parts.
- → Useful for MOC builders deciding which retired set to source for rare elements.
- → Compare a battle pack with a larger set to see if the small set is worth buying separately.
