How to Sort LEGO Parts: Storage That Speeds Up Building

If you have been building for a while, you know the scene: you want a red 1x2 tile and you spend ten full minutes digging through a mixed pile. The bigger your collection gets, the more urgent the question of how to sort LEGO parts becomes. A good sorting and storage system does more than save time — it keeps your head clear while you build.

Why bother sorting parts at all?

A lot of new builders treat sorting as a "later" job, something to deal with once the collection grows. In my experience, the earlier you build the habit, the better. Three reasons:

1. Faster building: with a clearly sorted system, time spent hunting for parts can drop by more than 80%
2. Clearer inventory: you always know what you own, so you stop buying duplicates
3. More inspiration: when every available part is visible at a glance, combinations and ideas suggest themselves

Common ways to sort parts

Method 1: Sort by part type (best for beginners)

Sorting by type is the most intuitive and most common approach. You group parts by shape and function:

Basic bricks: standard bricks in 2x4, 2x2, 1x2, 1x1 and so on Plates: plates in all sizes Slopes: sloped parts in every angle and direction Tiles: smooth-topped parts in all sizes Specialty parts: doors, windows, wheels, plants, minifigure accessories

With this system you can jump straight to the right category for each step. For anyone new to sorting bricks, it is also the hardest to get wrong.

Method 2: Sort by colour (best for visual builders)

Some builders prefer grouping by colour — all the red parts together, all the blue parts together. It looks very tidy and makes it easy to grab parts that match a colour scheme.

It has one clear drawback: if you need a specific size, you have to dig through every part in that colour, which can actually be slower. So keep pure colour sorting for smaller collections (under 1,000 parts), or combine colour with type.

Method 3: Sort by use (best for advanced builders)

As you gain experience you start noticing that certain parts always show up together. That is the moment to sort by purpose:

• Architectural parts: bricks, plates, doors, windows, roof elements
• Vehicle parts: wheels, axles, windscreens, steering wheels
• Technic parts: gears, cross axles, pins, Technic beams
• Decorative parts: plants, flags, stickers, printed elements

This method demands a solid familiarity with your parts, but it makes themed building dramatically faster. Browse building or vehicle instructions on BrickPlans and you will notice how much the part mix changes from one theme to another — sorting by use maps directly onto that difference.

The recommended system

Combining the three methods gives a proven setup:

Tier 1: Big categories in large bins

Use four to six medium-to-large storage boxes and split parts into these groups:

• Bricks
• Plates
• Tiles & Slopes
• Technic
• Special & Decorative
• Minifigures & Accessories

Tier 2: Subdivided compartments

Inside each large box, use adjustable dividers to split further by size and colour. In the brick box, for example:

• 1x1 bricks
• 1x2 bricks
• 2x2 bricks
• 2x4 bricks
• Other sizes

Tier 3: Frequently used parts kept out

For the parts you reach for constantly — 1x1 plates, 1x2 bricks — keep a separate container on the desk within easy reach, so you are not opening boxes all the time.

Storage tools by collection size

Starter setup (under 500 parts)

• Clear zip bags: one bag per category, essentially zero cost
• Small compartment boxes: a small multi-compartment box from IKEA or MINISO is plenty

Mid-level setup (500-5,000 parts)

• Akro-Mils parts cabinet: the classic brick storage cabinet with drawers; model 10144 (44 drawers) is the best fit
• Stackable clear bins: Stack-On or similar brands, where the transparent sides let you see contents at a glance

Advanced setup (5,000+ parts)

• Custom storage system: a cabinet configured around your part count and building habits
• Label system: a label on every drawer or compartment listing the part number and name

One principle matters more than any product: the tools should serve your habits, not the other way round. Don't try to buy the most expensive system on day one. Start simple and upgrade as the collection grows.

Going digital: the advanced option

Once you pass 5,000 parts, eyeballing and memory stop being enough. Consider digital tools:

• BrickLink Wanted List: track which parts you own and how many
• Rebrickable Inventory: import your sets and loose-part stock
• Excel or Feishu spreadsheets: a homemade list recording part number, name, colour and quantity

The advantage is that when you open an instruction on BrickPlans, you can quickly check whether the required parts are already in your stock and avoid buying them again. Recording part numbers is also a genuinely good way to learn brick knowledge — you gradually memorise the numbers and what each part is for.

Keeping the system alive long term

Setting a system up is the easy part; maintaining it is the real work. A few habits help:

1. Put parts back as you build: after each step, return the leftovers to their place
2. Do a weekly check: spend ten minutes putting misplaced parts back where they belong
3. File new parts immediately: sort new arrivals straight away instead of piling them up for "later"
4. Reassess periodically: review the system every three to six months and adjust it as your part mix changes

There is no single right answer

How you sort LEGO parts has no standard answer — whatever suits you best is the best method. Whether you choose type, colour or use as your starting point, the goal is the same: a smoother, more enjoyable build.

Start sorting your parts today. When you're done, head over to BrickPlans and pick out an instruction you have been wanting to build — then feel how much smoother the whole process runs with a storage system behind it.
