Most Common LEGO Parts (All Years)

This page shows the most common LEGO parts based on the assumption that you bought one of every set ever released! This is a very good way to approximate the most common parts across The LEGO Group's 70-year history producing interlocking plastic bricks.

Parts sorted by the overall ranking for each part. This is a weighted scoring system that takes into account the number of pieces, the number of sets, and the number of unique colors.
