I understand the BAG. I grew up swimming and my shoulders and back are bigger than normal and throws me into a bigger size. I have a V shaped back. chest measures 39 relaxedHi,
For me the msot important measurements are the pit to pit and the bottom hem.
I am very V shaped, so i need to know if the jacket will be a bag on me before anything else.
I have 42" chest, i like 22.5" pit to pit, i know from experience that i can wear anything from 21.5" to 24.5" (3" range") without problems.
I then move on to the bottom hem, i know 19.5" side to side is tight, 20.5" is perfect, anything above 21 that isn't belted will look like a bag and have a massive overhang (2" range)' That to me is probably the most important measurement, it's the difference between a good fit and a bag.
I then look at sleeve length, i know that 25.5" with 19.5" shoulders will work well and give me wrist bone sleeves.
Starting from there i can extraplate different combinations, if the jacket has wider shoulders i can afford to have shorter sleeves, if the shoulders are narrower i know i need longer sleeves. I have jackets with soulders ranging from 18.5" up to 21" and sleeves from 25" to 27.5".
Back length depends on models, but for motorcycle jackets i go 25.5, for halfbelts 26.5, for longer coats 28.5 to 30.5
IMO the less important measurement on a leather jacket is shoulder to shoulder.
An important thing to keep in mind is that numbers don't mean everything.
I have bought jackets that had "good numbers" that ended up not fitting, and i have bought jackets with numbers that made no sens whatsoever that ended up a perfect fit.
Have a look at this thread, i uploaded a bunch of fit pics with the numbers of each jackets, it has really helped me figure out how numbers affected fit:

My shoulder window is approximately 1.25 inches -- anything larger falls off my shoulder (or creates peaked shoulders)
They seem to just be rather wide fitting and kind of odd. Maybe not the best pattern for a V-shaped torso?
welcome to the club. Now you sell all your other jackets and buy new ones. Happened to me. Happened to others. Will happen again. The blessing/curse of this placeI made myself wear this jacket all day today driving around and running errands and it fits me I've decided.
I am in size shock none of my coats are short to begin with and they all are roomy.
I agree with others that shoulder width is the least important measurement in terms of fit. Personally, I think the 'right' shoulder width depends mostly on the type of jacket and the look that goes with it.
Left: 21" Right: 18'

21" works great for the CHP jacket on the left, but would look awful on the cafe racer on the right.
