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 which have not been included in sets from the last 5 years are considered 'Retired' and marked with an (R) symbol.

These results are sorted by the number of years that this part was produced, from the year that the first set containing this part was produced to the last year.
