Well, you measure it as it would be measured on a drawing, which is what it was made from. No need to over-think this. The only thing that isn't measured center-to-center is the seat tube length (when describing a frame) (sometimes). Think line drawings - where do the tubes' centerlines intersect, and where is the center line of things like the axles? Measure to those points. Greg Parker Ann Arbor, MI

"So, how does one measure stay length?
To my uneducated point of view, I don't know what the precise end points would be. For example, on the drop-out end, there's: the depth of the slot in the stay for the drop-out; the tip stay."
To which Doug replied:
I don't know the precise answer to that in frame builder's jargon, but for the purposes of comparison I think all we need is consistency in process. I would propose center of BB spindle to rear-most point of drop out slot as a measure of "effective" chainstay length.
On my 23.5" International it is 17 5/8", or using 2.54 cm to inch conversion, 44.77cm. I would consider it "long" as I have plenty of room to mount a frame pump on the backside of the seat tube and still easily install the rear wheel.
