The LEGO Parts Guide

Current Most Common LEGO Parts (2019-2023)

This page shows the most common LEGO parts based on the assumption that you bought one of every set released in 2019-2023. This is a good way to approximate the most common parts that are produced in this five-year span, and also a good predictor of the parts that you will have in large quantities in your own collection. (For storage ideas, check out my LEGO Storage Guide.)

Sets from 2024 are not included because many 2024 sets have not been released or inventoried yet — including them would create a lot of noise in the rankings.

These results are 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.
