Easy DIY Lego Organizer

Looking for a simple way to sort and organize your LEGO bricks? This super simple DIY LEGO organizer is exactly what you need!

I have a confession.
One time, when we were cleaning out my oldest son’s room, I texted Corey at work and asked if I could just toss all of his LEGO bricks so we could start fresh and actually keep them organized. I think he almost had a heart attack.
Our kiddo is a huge fan of LEGO, but we’ve never done a good job of keeping them in any way organized. They were just tossed into a couple of plastic bins – which, honestly, meant that he didn’t play with them all that often. It was so hard to find anything!
When I sent my poor husband that text, though, he knew I had had enough of the chaos. So, he offered to come up with a solution. And, y’all, he delivered. We got all of our LEGO organized and sorted and I had to come share this easy little DIY that will change the way you store your LEGO bricks forever.

How to Create the LEGO Organizer:

This project is easy. It’s just a few simple steps – here’s what I did:
- Start by determining the general size of LEGO brick you want in each box. The image above shows the bricks we used to determine sizing for ours.
- Grab your largest forstner bit and attach it to the drill, then grab the top plastic bin. Drill several holes in the bottom of the bin. Drill slowly!
- Grab a bit that’s sized slightly smaller than the next size of LEGO (meaning, you want that size to not fall through the hole). Repeat the process. For the smaller holes, you’ll probably drill more of them!
- Continue until you’ve drilled increasingly smaller holes in 3 of the 4 bins (obviously, the bottom bin will have no holes in it).
It’ll look a little like this when you’re done:


Now comes the fun part. Stack all of the bins together and attach the handles, then grab your LEGO bricks and dump!
The smaller LEGO bricks will automatically fall through the holes, and they’ll sort themselves. You may need to shake it up a bit (we also opened up each bin and manually moved the LEGO bricks around a little to help them fall through). Once you’ve shaken it up a little, you can open it and bask in the glory of LEGO bricks that are sorted (roughly) by size!

This was the simplest project ever (it took less than an hour!) but it was the perfect way to get the LEGO bricks organized. Our son was so excited to see how much easier it will be to find what he’s looking for, and I have a feeling he’ll be playing with them a lot more often now.
There’s also just something about knowing that the LEGO collection is nice and organized that makes me feel more on top of things. Like, my house is 5% cleaner just because of this project. It’s science.

Do you have any other genius toy organization tricks?

Play on a blanket that way when he gets done playing he can just pick the blanket up and dump it right into the tubs instead of having pieces all over the floor. When my collection grew and I realized I had to start sorting them out i did it by color. The problem with that is is that you get Lego blind. If you are searching for a 1x1x1 red piece in a bin of red pieces all you see is red. When my collection grew big enough that that became more of a problem I had to resort by piece type so I would just advise to sort by piece type in the first place. $300 worth of storage bins just to put your Lego in is kind of crazy. Try to keep your bins the same size that way everything stacks on top of each other and buy extra bins at the same time because you’re always going to grow into new bins. Fishing tackle boxes help out with all the little cubby holes.
What containers did you use? Can’t find a 4 level container anywhere.
We found ours at Target!
You’ll need two of these to get 4 layers. https://www.amazon.com/Sterilite-1427CLR-Stack-Carry-See-through/dp/B01M12WWPI/ref=sr_1_2?crid=13A1TSBYE1N83&dchild=1&keywords=sterilite+2+layer+stack+and+carry&qid=1598830120&sprefix=sterilite+2+layer%2Caps%2C288&sr=8-2
Office depot has a lot of them and they stack i got mine there!!
What size bits did you end up using? Would you change the sizes based on experience so far? Thanks!
They ranged from 1/2″ to 3″! It has continued to work really well for us!
Thanks!
This is a great system to organize his current Lego collection! What I’m about to say will come as no surprise, but you’ll certainly need to evolve your storage system as his collection grows. I have four-Lego lovers, who have been collecting sets for a total of twenty years between them, and the number of Legos they have is staggering! When you get there, I’d suggest sorting by size as you’ve done, but also by type (vehicle parts, people paraphernalia, weird shapes versus basic bricks). Makes the hunt for that perfect piece a little easier! Good luck (and watch your step 😉)!
Definitely! I think this will always be able to function as a good base system, and we can pull other pieces as needed once they’re sorted. Anything is better than what we were doing before. 😉
