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.

The LEGO Parts Guide is a work in progress

This is a handcrafted experience to help you browse LEGO parts in a simpler way. If you have ideas to make it better or encounter any issues, please send me an email at tom@tomalphin.com — Thanks!

Check out the About the LEGO Parts Guide page to learn more about why I created this guide. It also includes a detailed version history with images of early prototypes of this guide.
