# Describing lego brick dimensions in Japanese

In English in order to describe a Lego brick which has dimensions or 2 pegs by 4 pegs, we could say "2 x 4" and pronounce this "2 by 4". How is this expressed in Japanese?

I have seen "2 x 4" written on a Japanese lego site, but would this be pronounced "二　カケル　ヨン"?

I assume this is similar to how one would describe a matrix in Japanese (like in English), but if anyone knows any specific lego terms let me know.

Also, to describe a brick with those dimensions would "2 x 4" be sufficient, or is it better to say "2 x 4 (の)ブリック"?

I'd say

ニ カケル ヨン の レゴブロック

though I never had a chance to describe the dimension of a LEGO brick in Japanese. I didn't order them some 27 yrs ago, my parents did :-)

Most Japanese don't understand what is a "brick." LEGO bricks are known as レゴブロック [LEGO block], or simply レゴ, in Japan.

I believe dimensions are read as:

A対{たい}B

Same as in mathematics when you have a ratio such as:

A:B

Also, bricks are commonly called blocks in Japanese.

• Thanks, I didn't know about that way of saying it. I found this site which says "2x4ブリック", which usage do you think is more common? technicfreaks.shop-pro.jp/… – Locksleyu Mar 11 '16 at 13:09
• @Locksleyu interesting. I haven't heard that one before, but it seems prevalent on the web. – Amani Kilumanga Mar 11 '16 at 13:11
• This is interesing, because in a ratio, this is a division (:). In the case of a Lego brick, or say, a grid, this is a multiplication (×). I’d like to hear from a native Japanese, how they’d read stuff like “4×2のブロック” or “3×3のマス”. – Glutexo Nov 26 '17 at 15:06
