LEGO Ruler and Sorting Tool

This article is the second in the series about buying and selling used Lego.

I don’t know about you, but I can easily distinguish a 1×2 from a 1×3 at a glance, but I can’t tell the size of larger parts without counting the studs. Technic axles are even harder to tell apart at a glance since they don’t have visible studs. When I started sorting through my craigslist collection, I looked online to find a printable guide to help sort the various lengths of Technic Beams and Axles. I found a simple tool which I used for a while, but knew I could make something better.

Figuring that I could improve on the design, I have created the following printable tool to help you sort your Lego bricks. It has been enhanced to show Technics angled pieces, the basic dimensions of a Lego brick, and includes two rulers along the edges of the paper.

To measure a plate, align it with the lower-left corner to see its width and height. To measure the height of a part, use the ruler on the right edge of the printout.

Directions to make your own Lego sorting tool and ruler:

  1. Download my Lego sorting tool and ruler (version 1.1)
  2. Make sure to print it at “100%” scaling factor. I designed it to fit on both an 8.5×11 inch (US) and European A4 Paper.
  3. If you have access to a laminating machine, laminate the page to make it more rigid and durable. If not, try to print it on thick paper or cardstock.
I hope you find this tool helpful. Liked it? Pin this to your wall or share it with your friends. If you have ideas how to make it better, let me know by leaving a comment below!

    Tom, do you have a vector graphic format of this available? I’d like to use it with my laser engraver to make a slightly more sturdy version… and maybe something with enough depth that I can drop the Technic axles into a slot to measure.

  3. Larry says:

    Ian – take a look at this ruler. It has slots for Technic axles and works beautifully with all Lego. It’s made by Lego but very hard to find. I have a few of them and use them all the time.

    Ian, a PDF file is a vector graphic file, just try to open it in Illustrator.

    Hey Tom, I really liked your initiative to do a Lego challenge. I bought the set and I’m thinking in trying a project as yours, but weekly. 🙂

  6. Jennifer says:

    ok so my son has over 10k in Legos. I live in Kc and can’t seem to find anyone to buy incomplete sets. Would anyone know where to sell? Or should I start sorting? Do you take sets Apart? I don’t have some books to go with sets. Help!!!

      Hi Jennifer,
      You can sell anything on bricklink.com. It allows you to state whether it is new or used, and what is missing (such as the instructions, box, stickers and so on).

    Thanx! You just saved me 3 hours of support 🙂

    Mindstorms is cool, but there is no ruler in the box.

    • Tom Alphin says:

      Axel, Glad to hear that the ruler is helpful. I have two copies in the house, both laminated. One is upstairs with the LEGO collection, and another is in the office by the computer!
