Wotcha think you're doin' here then? You think you can just waddle in like that, do ya?

This here, laddie, is a top-secret Brickspace testin' ground. Yup, thassright. So you'd better geddout before someone sees ya pokin' around...

Brickspace Dictionary: n x n x n

n x n x n (n.)
When measuring Lego bricks, we usually use the n x n x n system. This is much like normal measurements in which we provide the width x length x height of the brick, though sometimes the height is not required.

Most Lego bricks and plates can be classed as either 1xn or 2xn. In these examples, n could be any number. So 1xn means any brick that has one of its measurements (apart from height) as 1. This could be a 1x2 brick, a 1x4 brick or even a 1x16 brick! Similarly, 2xn bricks can have any length, but have to have a width of 2 (we usually put the shortest measurement as the width, but in the case of square (eg. 2x2) bricks, it doesn't matter).

This measuring system has a flaw, however: the units of width and length (sometimes shown by (a square)) are not the same as the unit of height (sometimes shown by (a diamond)). However, they can be interchanged using the 5:6 ratio, which is that every 5 brick height units equals 6 horizontal stud units.

You may often see a brick has a height of 2/3 (eg. 2 x 2 x 2/3). This is the only height measurement <1, because for every one height unit, three plates can take its place. Thus, 2/3 means that the brick is two plates high: say, for example, a cheese wedge. As I said, this is the only fraction measurement: 1/3 would just be a plate, and 3/3 is a whole, a 1.

The width and length measurements can also be fractions, though only 1/2s. If you use a jumper plate (a 1 x 2 plate with a single stud in the middle of it), you can offset the length or width by 1/2.
