Where to take door way measurements?

[AaronBarnett]

I am currently working on my interior door design and I am close to starting the archway and building my templet. I know the door height should be 63% of the total dome height my question is where is that measurement taken? It would seem to be a very different measurement if taken at the side of the door (lowest part) or in the middle (highest part) because of the arched opening.

I have looked through several other posts and read through the downloadable instructions and can't seem to find an answer.

Thanks ahead of time for the help

Welcome Aaron! The "golden" 63% ratio is the inner arch peak height over the height of the inner dome chamber. Be aware that the dome design works very well within a fairly large range of opening/dome height ratios. Also be conscious of making your opening wide enough to fit in your favorite turkey roaster (with turkey ) or a sheet pan. Hope that helps.

Perfect! Thanks Mike!
