How do you get a MS Word document to print in the correct size of a standard letter page from a website you are building?

Question

I cannot get a word document installed into my website in such a way that it prints as a standard sized document. I have tried converting it to an htm file in Word, but it still prints larger than one standard page. If I knew how to make a table the exact size of a standard Word document or letter paper I might be able to constrict the size in such
a way it would print correctly. Does anyone know a method to install a Word document so it prints the correct size from a website? I have tried to use a link to the word document but the document never comes up that way. Any help would be appreciated. I am a 68 year old retiree working as a volunteer for a non-profit group trying to build a new website for them. I would appreciate any help I can get.

I mean that any visitor to the website cannot get it to print as a standard letter sized document.It is the sizing from the website that is the problem.
