How to measure contact points

[SleepyCyclist]

Getting around to building up a frame I've had sitting for far too long. Thinking I should measure my current setup rather than just eyeballing it and making adjustments as I ride.

What/how are the key contact point measurements?
floor to saddle
saddle setback
saddle to handlebars

Dave Kirk had a really excellent post on just this thing last fall.
Should be everything you need

Key points are stack and reach position of handlebar center and saddle position relative to BB center.

If you measure relative to the floor, or saddle to handlebar, you are assuming that HTA, STA, and standover are the same for this bike as the one you are comparing to. To normalize for those differences, your reference point should be BB center.

To make things easy, put your bike in the corner of a room with the rear wheel touching one wall. Measure from BB center to wall, measure from saddle tip to wall, subtract = saddle setback. Do the same for your handlebar. Measure BB center to floor, handlebar center to floor, subtract = stack, BB center to wall, handle bar to wall for reach. Measure saddle height along the seat tube, again, from BB center.

Edit - or just read link in the post above - much better description.
