Why are we still using imperial dimensions for plywood?

    Hello,

    I am genuinely curious as to why we are still using imperial dimensions for plywood and other sheet material? I was hoping someone could give me a logical answer for this. Ireland and Europe use the metric system, our joist & stud spacing are done at 400mm centres, so why are the sheets we use 2440mm x 1220mm?

    Thanks in advance for your helpful and insightful answers 😃

    The answer is very simple. Its because the machines that make it are imperial. Maybe they can be changed but the product sells fine as it is and tradesmen are well used to the dimensions. If you look at any dimensional timber you'll find its size is basically imperial although with nominal measurements you need to know that the stated size isn't what you actually get. All timber lengths while metric are still to the nearest nominal imperial measurement in feet.

    Wake me up when it's all over.
