Forgive me for the awful first post.

I use the stand with my back against the wall method and use a framing square. I slide the square waaayy up there and put pressure against the pelvis. I guess it's actually my tail bone really. Anyway, is this the correct way to measure the inseam? I mean, how much pressure against the pelvis should there be?

I'm 5' 7" and I get around 32" with this method, but it's not fun.

I've been riding mountain bikes since 1993, and am realizing a road bike is in order too. Can I take certain measurements from my mountain bike to help me figure out desired measurements for a road frame?

Yeah, I have my wife or one of my kids mark the wall at the top of the square. I figured the width of the book could influence the measurement, so I figured I'd use something real narrow.

What is the make & model of the frame you have, and what size is it? My friend's brother-in-law is a Fuji dealer, so I'm probably going to lean that direction. My friend rides a 54cm Team Pro, with original stem and bars. I'm planning on taking it for a short spin around the neighborhood to determine if that is the correct size for me. When I first starting mountain biking, I road a fully rigid bike and used road bike fitting techniques to set up the stem, bars, seat, etc. However, that was a little while ago and I've forgotten most of that stuff. I'm just trying to refresh my memory so that I can try to get dialed.

Something wider

You are likely getting too high a number unless the framing square is quite wide. A 1" dowel or a book is the standard method.

There is little transfer from MTB measurements to road bike measurements. You'd be much better off to look at one of the on-line fit calculators for a starting point:
