Short arm/Mid Arm/Long arm how to tell?

So this a really n00b question but how do you tell the difference? im getting more serious with my jeep and am planning an axle swap soon and i want to do a new suspension set up and not have to buy one. I was leaning towards a double triangulated 4 link rear. I know imped has mid arms, b2carpen has long arms and im sure plenty of people with shorts just none come to mind. Whats the easiest way to tell difference and any good links to info on the subject?

If you want to build your own suspension stop worrying about labels. Get a 4 link calculator and play around with it. Figure out what lengths work for your build and goals. Don't worry about what it gets called.

Don't worry about labels. The only reason I even call mine 'mid arms' is because they're longer than stock arms but I've deliberately kept the mounts tucked as close as I can effectively get them to the tires for clearance. Don't worry about the labels AT ALL. If you want the arms as long as you can possibly get them, set the mounts up right next to the t-case skid. If you realize that that's just hurting your clearance and gaining you nothing, then input clearance concerns into your equation.

Just FYI, I've got my rear mounts pushed back as far as they can go on the frame before the wheel well arch starts and with the axle where it is, my lowers are 23" eye to eye. I made the front arms the same length and those mounts are positioned right below the front-most side body mounts. The reason I didn't mount them any further forward was because the upper link mount placement and attaining the vertical separation that I want would've been made very difficult. So, you can say that on both ends, the arms are as short as I can get them given my constraints. High clearance, great geometry, and full utilization of 12" travel shocks split 50/50 is what I was after and that's what I'll get.
