I find at least in my case there is no real single answer. I'm 6'3 with a 36" inseam and average torso length. Depending on the manufacturer I have trousers in normal and long or tall rise.

 

The rise is basically from the crotch to the top of the waistband.

So low rise would be a lower number, and so on.

Though it is a factor in the overall fit, it is not exclusive. Therefore my advice would be to try on slacks to find the best fit for you.

Same here. What pant brands do you prefer?

 

Low/high rise will probably feel the same if you have relatively flat stomach.

Higher rise will look better if you have the eye and know about balance. So take good pictures of yourself from front, side, and behind.

Higher rise will prevent your shirt from showing under your suit/sport jacket's front/quarters, so wear your jacket, stand in front of the mirror, and inspect.

 

It was my impression that rise was equal to outseam minus inseam. So, if outseam was 40", and inseam was 30", rise would be 10".

 

Lie the pants down flat, and measure the front along the fly from the crotch seam to the top of the waistband.
