Chainline question

Can someone explain how to measure chainline? I have a Kilo TT, and want to swap out the crankset. One of the cranksets I've looked at had a 49t chainring, any way to tell if it will clear the frame?

But specific design parameters, e.g chainstay length, stay indents, rear hub spacing, bottom bracket spindle spec, etc. all play onto this.
I'm asking two separate questions. Wound up finding a helpful article on chainline, so I'm good there. Need to have a way to make sure this will work before spending 300+ on a new bb and crankset.

Velomine has the Campy Record, but they won't let you return it if it is installed, so I'm trying to figure out what to do next.

this person cleared a 48t so i would assume 49t would fit

edit: it's got a dimpled chainstay so im pretty sure it'll clear up to at least 52t with the stock bb

Thanks. The 49 would be marginally larger. What is the length on the stock bb? Got a 110.5mm installed now, and the Campy is 111mm.
