Sometimes go for skinny lapel or wide lapel is for one specific look. Say, a double breasted jacket with skinny notch lapel would look bad no most of people.

Wide peaks, skinny notches. I would actually consider wearing wide peaks, would never go below a 2.75 or above a 3 in notch lapels (which may seem skinny, but it's proportionally ideal for me). However, if I had to pick a side to screw up on, wide notch lapels are a bit too Harry Callahan for me. I'd go skinny notches.
Just out of curiosity, one measures the width of the lapel at the widest point with the tape perpendicular to the fold (crease, roll) of the lapel, correct?
a fully canvassed sport coat that fit perfectly, was my basic style, and was
deeply discounted, because it had 3" lapels. All my other jackets/suits have 3 1/2"
or even a tad wider. I bought the jacket and wear it. I still think it would be perfect
if the lapels were wider.
On a thin guy (34-40) I'd say it's proportionally right in the middle. I would never recommend going below 2.75" (what I wear) or above 3" (Also what I wear ) for those sizes.
