5 Tips for Sorting and Organizing Your LEGO Collection

Piece Pavilion · March 11, 2026

Every LEGO builder reaches the same point eventually: you open the bin to find one piece, and twenty minutes later you're still digging. Whether you have a shoebox of bricks or an entire room dedicated to your collection, a good sorting system saves you time and makes building a lot more enjoyable.

Here are five practical tips we've learned from years of sorting, selling, and building with LEGO.

1. Sort by Part Type, Not Color

This is the single most common debate in the LEGO community, and the experienced builders almost always land on the same answer: sort by part type first.

Here's why. When you're looking for a specific piece, you usually know what shape you need before you know what color. A bin full of 2x4 bricks in every color is easy to scan — you'll spot the red one immediately. But a bin full of "all red pieces" means digging through plates, tiles, slopes, Technic pieces, and more just to find a single brick.

Color sorting only makes sense for very small collections where everything fits in a few containers, or for specific projects where you're working with a limited palette.

2. Start Broad, Then Get Specific

Don't try to sort your entire collection into 50 categories on the first pass. You'll burn out before you're halfway through. Instead, start with broad categories:

• Bricks — Standard rectangular bricks (1x1, 1x2, 2x4, etc.)
• Plates — Flat pieces, one-third the height of a brick
• Tiles — Smooth plates with no studs on top
• Slopes and wedges — Angled pieces
• Technic — Beams, pins, gears, axles
• Minifigure parts — Heads, torsos, legs, accessories
• Specialty — Everything else (windows, doors, plants, animals, etc.)

Once you have these broad groups sorted, you can subdivide further as your collection grows. For example, your "plates" bin might eventually split into "1-wide plates," "2-wide plates," and "large plates."

3. Use the Right Storage

The container you use matters more than you'd think. Here are the most popular options among serious builders:

• Tackle boxes and craft organizers — Great for small parts like 1x1 tiles, studs, and minifigure accessories. The adjustable dividers let you customize compartment sizes.
• Drawer units (Akro-Mils, etc.) — The gold standard for medium to large collections. Small pull-out drawers let you label and access each part type quickly. Stack them on shelves for a compact setup.
• Zip-lock bags — Don't underestimate the humble zip bag. They're cheap, see-through, and great for temporary sorting or storing parts you don't access often. Label them with a marker.
• Shallow bins — For your most-used parts (common bricks and plates), shallow bins work better than deep ones. You can see everything without digging.

Avoid one common mistake: don't use containers that are too large. A huge bin of mixed bricks is exactly what you're trying to get away from. More smaller containers beat fewer large ones every time.

4. Keep an Inventory (Even a Simple One)

If you're serious about building or buying parts for specific projects, knowing what you already have saves money and time. You don't need a complicated spreadsheet — even a rough idea of your stock helps.

For builders who want to go further, BrickLink's catalog system is actually one of the best inventory tools available. You can create a "wanted list" of parts you need for a project, then check it against your collection before ordering. Many sellers (including us) use BrickLink's system to track every piece in our inventory.

At minimum, keep track of which sets you own and whether they're complete. This is especially useful if you ever decide to sell — complete sets are worth significantly more than incomplete ones.

5. Decide What to Keep and What to Let Go

Sorting is the perfect time to be honest about what you'll actually use. If you've got pieces from themes you're no longer interested in, duplicates you'll never need, or partial sets that are missing too many parts to complete — it might be time to pass them along.

You have a few options:

• Sell them yourself — List individual pieces or sets on BrickLink or other marketplaces.
• Sell in bulk — If you don't want to deal with individual listings, many buyers (including us) will purchase bulk lots by weight.
• Consign through a store — For higher-value sets or rare finds, consignment through an established BrickLink store means you get a better price without doing the listing, shipping, and customer service work yourself.

At Piece Pavilion, we both buy bricks outright and offer a consignment program for higher-value items. If you've sorted your collection and found pieces or sets you're ready to part with, we'd love to hear from you.
