The height of the 1x1x1 LEGO brick is 6/5 times its width. Is there any particular reason for these proportions? And especially why not making a cubic brick (it would have made SNOT building easier)?

2In the same line: Why is a plate 1/3 of the brick's height? – pcantin Nov 4 '11 at 18:50

Probably to simulate real bricks: each of their dimensions are a different length. – wersimmon Nov 10 '11 at 23:08

In the 60s, Lego did produce a separate system for architectural modelling called Modulex which used a 1:1 ratio 5mm cube as its basic brick. It wasn't successful and was discontinued in the late 60s.
I believe the 6:5 was chosen so that studs could fit into the geometry. Related: why the plate is 1/3 of the brick's height. By adding two plates to the height of the brick vertically you can now match the centres of two horizontal units (6+2+2):(5+5)

7Thanks for your answer. Your explanation for the height of a plate is indeed quite convincing. I'm not sure I understand what you mean by studs fitting in the geometry though. Could you please elaborate ? – Joel Cohen Nov 5 '11 at 4:10

4@ghoppe: I'm confused. Didn't the bricks with holes in come years after the plates? Were Lego really planning that far ahead? OTOH, I can't imagine that the geometry you describe is a happy coincidence. – Kramii Nov 5 '11 at 8:02

From everything I've seen, the geometry is very well thought out and seems to cover all eventualities (or was just very lucky :o) – Deanna Dec 6 '11 at 10:18
