You can use your hand for a quick measurement of angles. Spread out your fingers as far as they can. Your little finger represents 0°. The angle between the thumb and the little finger will be 90°, the angles between the little finger and the other fingers are 30°, 45°, and 60°, respectively.

Best of the new year to you David. I don’t use mine for angles so much but for rough measurements I can be pretty close using my 9 1/2” span from thumb to pinky. I use that a lot.
Thanks for the “finger tip”. :-)

David,
Man, I must be dense or drank too much last night.. BUT, I cannot see 90° between thumb & little finger… tip to tip?
I think I can see 30° between little finger & ring finger…
When I open rt.hand, I measure 8-5/8” from tip of little finger to tip of thumb…
I think I need a picture / diagram… :(
How do input the degree mark? Push ALT + a number? What is the Number? Seems like Years ago I saw this…
I found it Here.
Happy New Year!

joe
lets start with dense as the operating principal
something we can all understand
this pic is what the angle is about

paul was not talking about the angle
but about his rule of hand measuring tip to tip
straight across his hand
two different things
aside from all that
how much did you have to drink last night

Happy New Year David. Good to see you out and about.
My little paw measures 9 1/4” Lil’ finger to thumb. But the Lil’ finger Thumb angle is off quite a bit; 45°. I figured out a correction factor; cube my height in feet, divide that product by 3, then subtract 10 and it will give the correction to 90° in degrees ;-)

now we’re getting down to it bob
easier than getting out all those expensive tools
we can’t find anymore
just to figure out if our hand
is the right size to do any work at all
so long as we continue to fix the things we make
we good to go

My splayed hand is about 110° or so. I can hit 30°, 45°, 60° and 90° by eye tighter than with my splayed hand. My finger angles vary quite a bit.
Measuring 30° is 1:2, 45° is 1:1, and 60° is 2:1 (remember chief SOHCAHTOA). Simple ratios, easy to measure, easy to remember, perfectly accurate.
Now for a ‘rule of thumb’: One inch was defined as the width of the king’s thumb and to this day the average male thumb is almost exactly 1” at its widest point.
On a tangential note, I play a little game where I set the fence by eye and then measure to see where it actually lands just to see how close I can get. For under 1” I can usually eyeball to 1/16” or less. You?
