CHAPTER 5: LEGO Storage for Large Collections

Do you purchase multiple copies of a LEGO set because it includes great parts? Do you have a whole room dedicated to your LEGO collection? Have you been collecting since the 80’s? Your “Large” LEGO Collection needs to be really well organized, and you need to find the perfect storage solution for your home.

This chapter looks at storage solutions for advanced LEGO builders with a very large collection of bricks. These “Large” LEGO collections range from 50,000 bricks to well over a million bricks, and are typically sorted by part. Some extremely large collections are sorted by element (separate container for each unique color of each part). Because this chapter covers a wide ranges of collections, it includes many LEGO storage solutions, including professional storage solutions which are typically used in an industrial setting.

If you have a modest collection of bricks and you don’t want to sort by part, go back to Chapter 4: LEGO Storage for Medium Collections.

If you aren’t sure how you should organize your collection, start with Section I: Organizing, Sorting, & Storing LEGO Bricks.

Drawer Cabinets

One of the most popular storage solutions among AFOL’s with large collections are Plastic Drawer Cabinets. They are reasonably priced, and with more than 50 drawers per cabinet you can sort your pieces by Part, or even by Element (Part + Color).

Akro-Mils drawer cabinets are very popular.  They are high-quality and cost effective.

Akro-Mils drawer cabinets are very popular. They are high-quality and cost effective.

Best for:

  • Well organized collections
  • Lots of wall space

Also good for:

You can remove a drawer to bring the parts you need to your build area. Labels make it even easier to find the part you need.

Selection and quality varies greatly, with only one or two brands receiving the majority of attention in a given region. In the United States, the most common choice is the Akro-Mils products, but the Stack-on products are also popular. Some models can be stacked several units high, while others require wall mounting.

Features to look for in these cabinets include: flexible drawers (which bend instead of breaking), drawers that can be removed easily, drawers that can be stacked when they are removed from the cabinet, and drawers that are the right size for your needs.

Recommended Products:
  • Akro-Mils Drawer Cabinets – Plastic drawer cabinets by Akro-Mils are the top pick of most LEGO Enthusiasts in the USA. They have several advantages over other options including: drawers are easily removed and stack-able, drawers are deep enough for 16-stud bricks, drawers are flexible which makes them hard to break, and have competitive prices. All three cabinet sizes are 20″ x 6 ⅜″ x 15 ¾″ h (50.8cm x 16.2cm x 40cm h). They can be wall mounted, or stacked up to three units high. I strongly recommend the 64-drawer cabinet for most scenarios, but some people will want to use the 24-drawer cabinet for common elements or minifig accessories. There is also a 44-drawer cabinet with both large and small drawers.

    The small drawers have interior measurements of 5.0cm × 13.3cm × 3.7cm h (2″ × 5 ¼″ × 1 ½″ h), and a volume of 0.25 liters (15 1/4 in³).

    The large drawers have interior measurements of 10.8cm × 13.3cm × 5.3cm h (4 ¼″ × 5 ¼″ × 2″ h), and a volume of 0.76 liters (46 1/3 in³).

  • Stack on Drawer Cabinets – The Stack-on brand is also popular and well made. The cabinets are taller than they are wide, which might be easier in your home. The drawers are not stackable, which is less convenient when carrying drawers around your workspace. As with the Akro-Mils product, they come in three sizes: 60 small drawers, 18 large drawers, and a mix of 39 small and large drawers.

Drawers with dividers

If you want to store your LEGO collection like the LEGO design studios in Billund, you want large drawers with divided compartments. Drawers with dividers allow you to keep a large collection meticulously organized, and they take up less wall space than the drawer cabinets highlighted above. These cabinets are especially well suited for people who want to separate pieces by Element (Part + Color) instead of just by Part.

Best for:

  • Well organized collections
  • Limited Wall Space

Also good for:

Especially well suited to collections sorted by Element (Part + Color).

I have seen beautiful examples of drawers with every common brick and plate of a single color in one cabinet, or alternately, every color of a single part in a single drawer. Which organizational scheme you pick will depend on whether you think about the LEGO library of elements by color first, or by part first.

Recommended Products:
  • Really-Useful Scrapbooking Drawers – In addition to making premium storage boxes, the Really Useful Box company also makes quality stacking drawers for scrapbooking, and a divided insert which gives you 15 compartments per drawer for storing LEGO parts up to 12-studs long.

    Since scrapbook paper is 12″ x 12″ (30×30 cm) these are big drawers that can hold a lot of LEGO Bricks. With the insert, each of the 15 divided compartments are 10.5cm x 7.0cm x 7.5cm h (4 1/8 x 2 3/4″ x 2.9″ h), and a volume of 0.55 liters (33.6 in³).

  • Papimax LEGO Storage Drawers – This UK company makes the only storage drawers designed specifically for LEGO Bricks.

    Each drawer is 37cm x 23cm x 6cm h (14.5″ x 9″ x 2 1/3″ h), with a total volume of 5.1 liters (311 in³). Drawers can be configured with up to 15 compartments measuring about 7cm x 7.5cm x 6cm h (2 3/4″ x 3″ x 2 1/3″ h), and a volume of 0.32 liters (19 1/4 in³). Each drawer is about 1/3 smaller than the Really Useful Scrapbooking drawers.

Note: Neither of these products are readily available in the US at this time. I’ve contacted both companies about expanded global availability.

Removable Compartment Organizers

One of the newest products to gain popularity with LEGO builders is a new kind of tackle box with removable compartments. Many LEGO builders like how these have tight-fitting lids, but you can remove just one compartment and bring it to your build area.

Removable Compartment organizers are versatile and have tight-fitting lids to keep pieces in place.

Best for:

  • Well organized collections
  • Portability

Also good for:

You can remove a single compartment to bring the parts you need to your build area.

Most brands offer both a regular, and deep option. The shallower options are better for people who want a lot of small storage containers, especially when sorting by Part, or by both Part and Color (by Element). You typically get more compartments this way, and they aren’t as deep so it’s easier to remove parts from the bottom of each compartment. The deeper options only make sense if you sort by both part and color, and have a lot of basic bricks that you need to store.

Tackle Boxes

Tackle boxes are popular in the crafting community, and they are popular with LEGO enthusiasts as well. These containers have divided compartments and a tight fitting lid, and are less expensive than some other options. The most common designs have a lid which is attached to the base with a hinge, and the size of each compartment is often adjustable with plastic dividers.

Plano 3700 Series tackle boxes can store a lot of LEGO bricks.

Plano 3700 Series tackle boxes can store a lot of LEGO bricks.

Best for:

  • Portability
  • Inexpensive
  • High storage density
  • Stackable

Accessing a specific part is a bit slower than some other solutions, as you need to find the right container, fold it open, and carefully remove the parts you need without causing an earthquake (where parts end up shifting into the wrong compartment.) That said, they are extremely portable, making them a great choice for younger builders, or people who need to bring parts to a LEGO convention. It’s also a good deep storage option for well-organized builders who need an inexpensive and efficient storage solution for less frequently used parts.

Recommended Products:
  • Plano Tackle Boxes – Tackle boxes come in a wide range of sizes, but the larger sizes can hold more LEGO bricks. I recommend the 3700 Series which is 14″ x 9.25″ x 2″ tall, and has up to 24 compartments. The smaller 3600 Series is 11″ x 7.25″ x 1.75″ tall, with up to 21 compartments. (Anything smaller than this is probably too small for LEGO bricks.)
  • Plano Multi-tray Tackle Box – For the ultimate in well-organized portable storage, consider one of these large tackle boxes which store up to four tackle box trays. The Plano 1374 Rack System holds four of the 3700 Series Tackle Boxes recommended above.

Plastic Bags

Plastic bags are one of the cheapest and most commonly used LEGO storage containers. It helps that they are very easy to find — you can buy them at almost any grocery store. That said, not all bags are created equal… Premium bags don’t cost much more, but they include convenient Sliding zippers, and are designed to stand up when placed on the ground. This might not seem like a big deal, but it’s really helpful since you can leave a bag unzipped without worrying about it falling over and spilling pieces all over your workspace.

Zippered Plastic Bags are inexpensive and versatile.

Zippered Plastic Bags are inexpensive and versatile.

Best for:

  • Low cost
  • High storage density
  • Overflow storage

Also good for:

Separating new and used bricks while storing them in the same container.

Plastic Bags are especially well suited as overflow storage for people with very large collections — you can stack a lot of bags in a box or large drawer without wasting space. (Plastic Bags are also useful for storing sets, manuals, or other LEGO accessories.)

I strongly recommend having bags available in all sizes: from the smallest 2″ x 3″ size to the largest 2.5 Gallon size — They are inexpensive, and you never know when you will need them!

Recommended Products:
  • Ziploc Slider Stand & Fill Bags – This is the premium option for storing LEGO bricks in bags. The slider makes it easier to open and close, and the bag stands up while you fill it. Available in Quart, Gallon, or a Variety packs. (For even larger quantities, or to store a complete LEGO set, try the Hefty Slider 2.5 Gallon Bag.)
  • Standard Plastic bags – The most common sizes are Sandwich, Quart, and Gallon. The name brand regular bags cost almost as much as the Slider bags, but you might be able to find inexpensive generic bags at your grocery store. The “Freezer” bags are thicker and more durable, but more expensive. (I really like the Snack Size, which is the same width as the Sandwich size, but half as tall. It’s perfect for small parts and accessories.)
  • Small Bags – If you’ve ever purchased LEGO bricks on Bricklink, you probably received some of them in very small plastic bags. The smallest size I can recommend are the 3″ x 5″ bags, which are cheap and can hold a fair number of pieces. (The 2″ x 3″ bags aren’t very useful, although they are large enough to store a couple bricks or a single LEGO Minifigure.)

Open-front Bins

Designed for industrial applications, some professional LEGO builders use open-front storage for commonly-used bricks. This storage solution takes up a lot of space, so it only makes sense if you have a very large quantity of common elements. For example, artists like Nathan Sawaya who use a large quantity of classic bricks to make large LEGO sculptures.

Not Recommended:

While they might make sense in the model shop at LEGOLAND, or the design studio of Nathan Sawaya, they aren’t very practical for most LEGO enthusiasts. The primary concerns are storage efficiency, cost, and dust.

The main concern with this storage solution is that it is expensive, takes up a lot of space, and pieces can fall out if the container is too full.

I’d love to hear if you use a different storage solution for your large collection. In the next chapter, we’ll look at some neat tricks to be more creative and organized.

    Hello Tom.

    Been reading this guide for quite some time since I wanted to sort my Legos in a proper way, and your job is really incredible. The only drawback for me as I live in France is that Akro Mils products aren’t available here, unless you are willing to spend a hundred euros for importing those. So here is what I found at a reasonable price :
    9€ for 30 cabinets, almost the same value per cabinet as for the Akro Mils’, stackable as well, seems like a good product for us non-US users 🙂
    I ordered 6 of them, I’ll let you know if you’re interested in it 😉

    • Tom Alphin says:

      Thanks for sharing. I look forward to hearing how well they work when they arrive!

        Hey Tom.

        So I received those Stanley drawers, and I have to say I’m quite happy with it 🙂 Here is a picture :

        Dimensions of the cabinets are similar to Akro Mils’, though you only fit 30 cabinets per drawer, but otherwise I guess it’s almost the same product. I plan to buy some more cause I just had enough place for 3 of my Technic cars and I still have a full travel bag full of Lego brick to sort out 🙂

        In a nutshell, I’d recommend this product for people who couldn’t get Akro Mils’ 😉

    I am new (returning) to the lego building world as my son (now 4) has graduated from Duplo’s and is now starting to build with Lego classic. I’ve already bought him several large classic sets to begin a base of building materials, and of course needed some sort of organization solution. The RUB drawers seem like an awesome option but you still can’t get the dividers in the US and they’re expensive. I also wanted something that he could bring from the storage area to the build area easily, with a lid and handle so he can’t spill and drop it. I was looking at the Stanley/Dewalt system and found an alternative that is much cheaper and similar to the FatMax organizers in the build quality and wanted to bring to your attention:
    Home Depot brand Husky makes these removable compartment organizers, only $10, and they lock together in a stack. The build quality is excellent and the gray bins make visibility excellent for all colors except maybe dark gray pieces. I’ve bought 3 already and they are great! The lids have dimpled areas that prevent pieces from escaping the bins, even if turned upside down. I am also considering building a custom wooden storage rack to allow them to slide in and out. Clear tops allow for excellent visibility. Unfortunately probably not available in the UK 🙁
    Thanks for the excellent write-up!

    Thank you so much for organizing all this information. As a Mom, I’m always overwhelmed by my boys Lego collection. I started organizing manuals and found out we have well over 100 sets. And now our summer project has been organizing all the pieces per your pdf label organizing system. Summer’s about half way over and we’re almost done. Just a couple days left to sort. Then I’ll put them in Akro Mills storage system. My kids initially balked at sorting but then they quickly realized how much easier it’ll be to free build when they don’t have to search forever through a big bin for that one tiny piece.
    Your website has been invaluable in helping me figure out how to sort and come up with a system that works for us. Thank you so much for putting this all together! Seriously grateful!

  4. John says:

    Hi I’m new here. I have around 260,000 bricks and I use the really useful boxes for my sorting and storage. I will include the link below. They all nest and can be keep inside the bigger really Useful Boxes. If you would like pictures I can do that also. Thank you
    John Look down to the bottom of the page. The different trays are excellent .

  5. Richie says:

    I don’t like the slider zippers on Ziploc bags. They are too easy to break and rarely stay properly locked. I really like the freezer type as they come with one longer lip that makes it easier to grip and open.

  6. Richie says:

    I’d like to see suggestions on best storage options for collections over 500K elements. As I mentioned before, storage space becomes an issue to manage. In my case, I need to look to these:

    • Tom Alphin says:

      Those high-density storage solutions are amazing, but well outside of reach for most of my readers. Thanks for sharing, though!

  7. N. Leenders says:

    For my technics collection, I use Shuter flip out bins. It is hard to express just how great they are to use, and my on-line search didn’t find any pictures to do them justice. These bins come in a variety of sizes, but they are modular, they connect together to create systems. So I have large bins on the bottom, medium next, and topped with small bins. I have these at the back of my table, and at my side, on a shelf, I do this again, three layers deep. The bins don’t fall over. I slide the front sets of bins to the side to access bins further back and thus have many quickly accessible parts next to me.

    • tomalphin says:

      This looks like a high quality product, but it’s pretty expensive. Thankfully, there are far fewer common elements in Technic than in System, so this might be a good premium recommendation for Technic builders. I’d love to see a photo!
