I've entered my stats several times and checked - as far as I can see I am doing it correctly, however the read out is not right, eg. 4cm for top length and 0cm for frame size?

anyone else have trouble

(I am entering all data in cm where length and am ensuring i click the cm drop box.)

I've used this site a number of times, although it has probably been a few months since I've referred anyone to the site. It is paramount to remember that this program is not designed to provide general fitting parameters, but fitting for WrenchScience custom bikes. That said, it does have some wider applicability. I've found that their recommendations generally run a bit larger for road bikes than I would recommend and a couple centimeters (2-4cm) larger for most tri frames.

It is not a bad place to start. I've had people ask me about fitting and I've referred them to the site to get them in the ballpark.

Good timing, as I just went through this last night. Although this site produced some useful general guidelines, I found the fitting tool at competitive cyclist to be much more useful.
