With the number of top pins for length and width, and heights given as 1/3, 2/3, 1 etc, What varieties are available? 1x1x1/3, 1x8x2/3, 2x2x1, for example.

What's the maximum size, length and width of such a block?

Are there basic blocks with fractional heights above 1?

Regarding odd lengths. I've seen bricks that are 1 and 3 pins wide or long, but none with odd measurements above 3. Do any like that exist with odd length or width above 3? For example 2x5x1 or 2x7x1, or 5x6x1.

  • 2x2x1 is just a normal 2x2 brick though, right?

  • If I understand you correctly, what you refer to as "pin" is more commonly referred to as "stud". Is my understanding correct ? Jun 3 at 15:34

Regarding odd lengths: Lego very recently started making 1 x 5 plates (and if you stack 3 of them, it's the same size as a brick). Otherwise, no.

1 x 5


I have compiled a spreadsheet showing all known size according to Bricklink: https://docs.google.com/spreadsheets/d/1vwCvSBmvaGz-Ucl1lTXI4tS55k6w1b2ih2mItxAWiis/edit?usp=sharing

It's hard to say what the 'largest' brick is, but here is some interesting data (only counting unmodified, rectangular parts):

Some other interesting dimensioned parts:

Baseplates also used to come in a lot of multiples of 5. Now they are all multiples of 8.
