I'm pretty sure the OP is talking about the angle of the hypotenuse and base of the triangle formed by the thumb and index (where the index is the base and the hypotenuse is the invisible line formed between the tip of the thumb and the tip of the index finger). I haven't measured mine but it looks pretty close to 30 to me.
Edit: BAD ASCII GRAPHIC where T = Thumb, I = Index and h = hypotenuse (no finger)
Angle ~ 30+(?) depending on ratio of thumb to index

Man do i agree LOL
i think some ppl read too much into the hole 30 degree angle and how tight there ridgeline is...
hang your hammock...if it feels good...then let it be
it doesn't need to be 30 degrees on the spot
once you start reading too much into 30 degree angles and this and that your start to overthink your setup....
just my .01
It puts the Underquilt on it's hammock ... It does this whenever it gets cold
Had to break out the trigonometry I learned 14 years ago to calculate this one. Let x = length of you index finger (measured to the joint of your thumb) and y = length of your thumb.
tan(30 deg) = y/x
x * tan(30 deg) = y
x * .57735 = y
or
x = y / .57735
So, if the length of your thumb is 3 inches (as mine is), then your index finger needs to be 5.2 inches long to make the 30 degree angle. Mine is ~5.6" (again, measure to your thumb joint), so my angle is slightly less:
tan-inverse(3/5.6) = ~28.17 degrees
Which I call "close enough".
Nice trick! Now I just have to take a few steps back, hold up my hands to frame my suspension and see if the suspension hits my index finger and thumb tips when the index finger is parallel.

WOW! Neat trick!! My "Pistol" is about 28 - 29 degrees (kids protractor that I couldn't find till just now) SO, close enough for me! Based on that, my current suspension (from last night) is around 25 degrees, so now I know I need to adjust it just a bit. I'm going to have to remember this.
When you have a backpack on, no matter where you are, you’re home.
PAIN is INEVITABLE. MISERY is OPTIONAL.
I'm not sure I understand...
Why is 30d the "norm?"
Why is 30 better than say 20 or 40?
I use a fixed ridge line and I like to pull my setup tighter... say 10-20 degrees...
Am I putting too much stress on the rig?
Thanks!
30* puts the least amount of stress on the set up, but many people opt to go tighter. The following thread discusses this quite in depth, and includes a nifty chart explaining how angles affect stress.

Hope this helps!
You're gonna need a bigger hammock
Ah! That does help.
Near perfect right angle (90°), with mine.
