Chapter 2: Organizing your LEGO Bricks

How to best organize your large (or growing) LEGO collection is an ongoing challenge for many LEGO builders. Let’s find the best solution for your collection.

Levels of Organization

Along the way, many people end up purchasing LEGO storage solutions that they outgrow or don’t work well. Even if you only have a small collection now, this guide helps you avoid common pitfalls by selecting an appropriate storage solution for your current collection which you can continue to use as your collection grows.

We’re going to to explore the most common ways to organize a LEGO collection, following the normal progression from no organization, to sorting by categories, and ultimately organizing by part.

No organization

When you have a limited number of bricks, it’s easier to find what you’re looking for. This is especially true for the small LEGO collections of young kids—organizing a 6-year old’s LEGO bricks probably won’t help them be more creative!

You will find the best storage solutions for small LEGO collections that don’t require any organization in Chapter 3: LEGO Storage for Small Collections.

Organizing into groups

If it becomes frustrating to find specific LEGO pieces because your collection has grown too large, it might be time to organize your collection into groups of related parts. Even if you aren’t keen to organize your bricks, it’s probably a good time to organize your parts into broad groups when your collection grows too large to fit in a single container.

Most LEGO builders recommend that you start by sorting your LEGO parts by category rather than by color.

Organizational groups:

  • Organizing by Color – Almost everyone begins by sorting their LEGO bricks by color. Unfortunately, most LEGO builders quickly discover that this makes it really hard to find a specific small part, as it’s hard to pick out a specific small part in a container full of bricks of the same color.
  • Organizing by Category – As you become familiar with common LEGO parts, you should try sorting them into categories based on their type. A good place to start would be to separate ‘Bricks’, ‘Plates’, and ‘Other’ LEGO parts into three different containers. (Even if you only have three categories, the next time you are looking for a specific part, you only need to dig through 1/3 as many parts since you know which of the three containers it should be in.)

As your collection continues to grow, you can make the categories more precise using additional storage containers. (For example, splitting a container filled with ‘Plates’ into ‘1x Plates’, ‘2x Plates’, and ‘Large Plates’.)

Whether you decide to sort by color, or by category, you will find storage suggestions in Chapter 4: LEGO Storage for Medium Collections.

Organizing by Part

As your collection grows even larger, sorting into categories will stop making sense — you’ll need to keep breaking categories into sub-categories as you get more and more pieces. Eventually, you will decide to sort the majority of your collection into separate containers for each unique part.

By Part vs. By Element:

  • By Part – If you sort by part, you will have a single container with identical parts that vary only in color. This is sufficient for most large collections, because It is easy for most people to distinguish between colors (making it unnecessary to also sort parts by color).
  • By Part + Color (By Element) – If you have a very large collection, you might have enough of the most common parts that you decide to also sort common parts by color. This is how LEGO parts are sorted at the LEGO Headquarters in Billund, Denmark. (Unless you have one of the largest private LEGO collections in the world, you are unlikely to sort anything beyond basic bricks, plates, and cheese slopes by both part and color.)

I’ve collected the best storage suggestions for collections sorted by Part (or by Element) in Chapter 5: LEGO Storage for Large Collections.

Where should I start?

By reading many discussions about LEGO storage and talking with LEGO builders at conventions, I’ve learned that biggest influence on the organizational strategies and storage solutions people pick is the size of their LEGO collection.

It's no surprise that larger LEGO collections are more organized than small ones.

While there are many organizational approaches you can try on the journey from a small LEGO collection to a collection with thousands of LEGO bricks, I’ve prepared the following suggestions based on the size of your LEGO collection.

Now that you better understand your collection and your organizational needs, let’s find the perfect storage solution!

    I posted on Reddit to you but I also wanted to ask/add here. Can we have a none specific to specific printable breakdown?
    Category has a picture breakdown. I can print those labels put and start my sorting.
    Then could we have a breakdown of part pictures that fall under each category? The amazing complexity of all the detailed pictures has a beginning sorter very overwhelmed. ❤️

      I also replied in Reddit, but yes – I think it would make sense to provide a ‘sorting guide’ that complements the label collection. No promises on when that would be ready, but it is a good idea!

    Tom – this is an amazing resource and I cannot thank you enough. My son (13) and I have gained quite the collection and it kind of got away from us before we realized the need for real organization… and it was a mountain of a task. Yes, your thoughtful and insightful guide has been instrumental to our process. More than that, this has also been great for understanding of the why and how to the organization (which has helped my spouse jump in and get on board as well). A million thanks!
