- Note! Approximate Lego dimensions in article
You must be logged in to reply.
Hi folks,
please note that the dimensions in this article are imperial unit approximations of metric values. For example, the stud pitch is actually 8mm, so approximating it as 5/16" (7.935mm) will give you an ever increasing error if you multiply out to 10x or 14x. All dimensions of Lego pieces are metric since it's a non-US company ;)
FYI I found a post with full dimensional information at http://www.lugnet.com/~330/FAQ/Build/dimensions
cheers,
Nick Donaldson.
