Last month, I launched a completely new LEGO Parts Guide which allows you to explore LEGO parts using a streamlined, well-organized alternative to sites like Bricklink or Rebrickable. I am thrilled to share a new experience that builds on the Parts Guide in an elegant way.

You may have already discovered the ranking data when browsing the Parts Guide — Rankings are now shown for every part.

I believe that having easy access to raking data will be tremendously helpful to people trying to organize their own LEGO Collections. Why? Because it gives people a much better sense about which parts are common and which ones are rare — You probably don’t need a dedicated drawer in your storage solution if a part isn’t very common (unless you have gone out of your way to acquire that part in bulk).

Parts are ranked on multiple dimensions, with a weighted ‘Overall Rank’ at the top which takes multiple metrics into account.

There are two ways to explore the Most Common LEGO Parts:

• Current Most Common LEGO Parts – Explore 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.

Explore the Current Most Common LEGO Parts, sorted by weighted ranking.

The ‘Overall Rank’ is weighted to highlight parts that are most common against three different measures – the sheer number of pieces produced of that part, the number of sets that the part comes in, and the number of unique colors that the part has been produced in. If you want to sort the list in a different way, you can click on the tabs along the top

One of my favorite views highlights those parts which have been produced for the longest time.

Looking Back: I first launched my original guide to the Most Common LEGO Parts in 2019. It was cobbled together using an embarrasing mix of Microsoft Access and Excel, which was exported as static HTML for use on the website. Even though I was unable to update it with new data very often, it grew to be one of the most popular resources at Brick Architect! That’s why I am so excited about this new experience — I can update it whenever I want by simply re-importing the inventories and re-calculating the results.
