How to Sort LEGO Parts: A Beginner's Storage System

Anyone who has built a set with several thousand pieces, or tackled a large MOC, knows the real bottleneck is rarely the building itself. It is the pile of loose parts on the table. Download a set of instructions from brickplan.cn, sit down to build, and you are faced with a mountain of mixed bricks where finding one specific piece feels like searching for a needle in a haystack. This guide walks through a practical sorting method, from the logic behind the categories to the containers you should buy, so you can build an organized storage system step by step.

Why sorting is worth the effort

Many beginners assume sorting wastes time. The opposite is true. A sensible sorting system can more than double your building efficiency. Once every part has a predictable home, finding a piece goes from five minutes of rummaging to three seconds of reaching. Just as important, proper sorting and storage protects parts from scratches and dust, which extends their life. If you build MOCs regularly, your parts collection is your ammunition depot, and how well that depot is organized directly determines how effective your builds can be.

Start with the big divisions: color and type first

The first step in any brick sorting method is establishing broad categories. Sort by color first, then by type. It is a process that moves from the macro to the micro.

Start with color families. Separate parts into main color groups such as black, white and gray; red, yellow and blue; green; and transparent pieces. Color comes first because it is the most visual and instantly recognizable attribute. When you build, you usually think "I need a red 2x4 brick" first, so color is the keyword that reaches your brain before anything else.

Then move to type. Within a single color, break things down further: plates, bricks, tiles, special pieces, minifigure accessories and so on. A common convention is "1x1 first", meaning you pull out the small, high-volume basic elements that are used most often. They are the parts you own in the largest quantities, and they are the ones that cause the most frustration when they are mixed together.

Refine into sub-categories by size and function

Once the broad categories exist, you can go deeper. For plates, sort by size (1x1, 1x2, 2x2, 2x4 and so on) into separate compartments. For special pieces, group by function: turntable bases, hinges, technic elements such as pins, axles and gears, and decorative parts.

One lesson worth borrowing: keep the granularity moderate. You do not need a dedicated compartment for every single size. If your variety of parts is very large, split them into "common sizes" and "everything else" at first, then refine as the collection grows. A sorting system is dynamic by nature. It should keep evolving with the size of your parts library and your building habits.

Choosing the right containers and tools

Even the best sorting method needs the right containers to hold it. These are the usual options:

• Compartment sorting boxes with removable dividers: good for storing common parts by type. The dividers can be rearranged freely, which makes them very flexible.
• Drawer storage cabinets: good for storing a large number of categories. Once labeled, everything is visible at a glance, and they are the first choice for heavy users.
• Zip bags and resealable bags: the best value for money. Good for keeping the parts of a specific set together or holding loose pieces temporarily, and they keep out dust and moisture.
• Clear plastic bottles or test tubes: excellent for small parts like 1x1 elements. Easy to grab, tidy on the shelf and good to look at.

Whichever option you pick, label everything clearly with the color and part type. That is what makes the "what you see is what you get" promise actually work when you are hunting for a piece.

Practical habits that keep the system running

A few small habits make sorting much easier. First, sort as you unpack: when a new set arrives, separate the parts by type before you start building, rather than digging through the pile as you go. Second, pull parts in instruction order: MOC instructions downloaded from brickplan.cn usually come with a clear parts list. Check your parts against that list first, then take them out in batches that match the build sequence. Third, put things back right away: return leftover parts to their places after every session instead of letting them sit out overnight. This one habit saves a huge amount of repeat sorting later.

Build your system one drawer at a time

Sorting bricks is not complicated. The core idea is: big categories first, sub-categories second, containers that fit, and habits that stick. A good sorting and storage system makes building smoother and keeps your collection in order. Whether you have just started out or already own tens of thousands of parts, you can begin today and set up a system of your own for your brick kingdom.
