In this guide you will find thousands of LEGO parts that have been meticulously orgasnized into 12 categories such as SNOT, Curved, Minifigure, Technic, and Electronics.

The LEGO Parts Guide, currently in private beta.

Each chapter includes text and illustrations to help you understand the many ways that LEGO parts connect to one another — and helps you build better models! While the focus is on current LEGO parts, historical anecdotes are included to help readers understand how the LEGO System in Play evolved over time.

Sample chapter text and illustrations explaining how SNOT pieces work.

It is designed as an interactive workbook with space for you to keep track of which parts you own (or want) and additional space for taking notes. I can’t wait for The LEGO Parts Guide to become an indispensable resource that inspires you to build something awesome!

The book includes a catalogue of more than 2000 current LEGO parts.

The LEGO Parts Guide initially launched as a meticulously organized online guide in 2024 and is being adapted into a printed book for release in 2026. The print version adds a lot of content not included in the online guide. Most notably, each of the 12 chapters includes an explanation of how the parts in that category work, some insights into how the parts were developed, and detailed illustrations showing how parts work together.

PDF and print copies of the beta version have been shared with Patrons.
