LEGO Techniques - System Sizes Wrap-up

Over the past several weeks I've been taking a look at different sizes of LEGO sub brands and comparing them to the System standard.  From little to big those have been Modulex, DUPLO, Quatro, Primo, and Tubs and Cups.  Unfortunately my collection is devoid of any Jumbo Bricks or Soft Bricks.  When and if I can get my hands on some I'll be sure to post about them.  From what I've seen on the interwebs, Jumbo is between DUPLO and Quatro in size while Soft Bricks are about the same size as Primo, stud notwithstanding.  Want to score mega bonus points with me?  Send me a yellow 2x2 Soft Brick and I'll gush about how wonderful you are in your very own blog post.

Some of these systems are immediately compatible with each other, some take a little more tinkering and ingenuity.  If you need a little help with size comparisons and what might fit where, take a look at the handy-dandy chart I created and made public.  If you have definitive dimensions to help fill any of the voids please feel free to share.  Jumbo Bricks and Soft Bricks could use the most help.

I feel like I did a good job of hitting all the sizes.  What else did I miss?


  1. What about the studs on the Schyling minifigure display case and the ones on the LEGO brick alarm clocks? I don't know if they're the same, I just don't think you mention either.

  2. Thanks for the tip. I own neither but I'll take my calipers to the store with me next time to see how they size up. I suppose there's also the large brick shape storage cases as well though I suspect they're the same size as tubs and cups.

  3. I just remembered about the salt and pepper shakers that look like 1 stud bricks. I'm not sure if those have a bottom designed to stack, though.

    1. According to this they stack. That review says they are 25mm wide but if that was rounding and they're really 24mm then were in business. Again, I'll pack my calipers in case I run across them sometime.
