This interactive guide helps you better understand the wide range of unique LEGO parts, with a focus on the most common parts you will find in current LEGO sets. I hope it helps you discover interesting parts you might have overlooked and identify a hierarchal sorting system that matches the way you like to build.
Getting Started
The LEGO Group produces thousands of unique parts which connect using more than a dozen different connection types. To help you better understand the vast range of LEGO parts, I've created lists of the most common parts, as well as organizing common parts into categories based on their overall function and the connection types they use.
Many people find this hierarchal approach beneficial when trying to understand how LEGO works or when designing the perfect LEGO storage system for your home. You may also notice that some parts could go in more than one category because they have multiple connections and functions. In these cases, parts are organized into the categories which match how the part is most commonly used. If you prefer to put it somewhere else, that's great — it's your LEGO Collection!
Because this is meant to be a practical guide, it focuses on the most common parts and ignores subtle part variations that rarely matter.
This guide is meant to complement other resources here at Brick Architect such as our LEGO Storage Guide and printable LEGO Brick Labels collection.
Explore the Most Common LEGO Parts
One way to explore the wide range of LEGO parts is to highlight the parts which are the most common, which is why I've created two galleries where you can explore the most common parts being produced in current sets, or the most common parts of all time.
- Current Most Common LEGO PartsExplore the parts which you are most likely to find in recent LEGO sets. (This is based on sets released in 2019-2023.)
- Most Common LEGO Parts (All Time)
Explore the most common parts across The LEGO Group's 70-year history producing interlocking plastic bricks.
