Some guys will tell you that weight matters, but they just don't know how to tell you what they mean by that. Ultimately, don't concern yourself with the number, because it doesn't mean anything.
What guys look for is how she carries herself, if whatever weight she has suits her, and if she is pretty either way. I have seen some full figured women that I find very unattractive, and very frequently, I find full figured women who are hotter than some of their skinny counterparts.
Don't kill yourself over skinny vs. chubby, that's missing the point. What matters is how the weight looks on you, and how you wear/carry yourself.
Depends on other factors. You can't determine it by weight alone. To a girl who's 5'10" or has denser bones, 100-115 lbs isn't skinny, its sickly and malnourished.
For the record I like women of all sizes, but my ideal woman is tall--about as tall as me (at 5'11") give or take, I would expect a healthy and active woman of that height to be in anywhere from 140-180 lbs unless she had a small/thin frame or little to no muscle mass.
First of all I'd like to comment on some oversights concerning the methodology with which you collect data. The hypothetical figures , however accurate on the average 1.70 woman might seem, exclude all women bellow or over that height.
now, to answer your question, some excess fat (about 3-5 kg or 6-10pounds, given that the conversion from metric to UK figures is correct) to the commonly accepted average weight used to be perceived as a sign of fertility (before the fashion industry , incapable as it is to see the beauty in a healthy human body). Thus , intuitively, I "prefer" the 130-140 / 1.70m girl
If the guy is trying to be realistic, it all depends on the built of the guy too. For me, since I am not too big, not too smal, and yet on the saller side, I would definitely go with Medium because generally that kind of girl would be in the 5'2" to 5'5" range and I love that. With that height range, everything about the girl looks good.
Weight isn't everything, once dated a girl who was 170 lbs but didn't look it at all. I actually like a touch of softness though so maybe I was biased. Also, some girls wear weight well and it actually looks flattering.
When I was younger, I preferred skinny. As I get older, I am more accepting of medium, and even large. Perhaps because that is what is available! But I still think that thin women with good muscle definition are particularly hot!
If I were 115 I'd be anorexic and my body would be shutting down. Taller girls weigh more. End of story. I know some girls who are 115 and are little porkers while tall girls at 155 are are skin and bones.
How the weight distributes depends on the height too - you can't just say that 100lbs is skinny - because it's pretty much the normal size for girls below 5'2. However, someone 6 foot tall may weigh a 150lbs and still appear skinny, because of how tall they are.
I guess I am medium cause I am short 109 pounds and 5'2 and size 0 waist 4 pants 34A chest and big biceps at least I get quite a few comments from other girls who seem me in a tank top burshing my hair ( wow you have huge biceps ) xD I like weighttraining running and sports too much.
I'm 27. 5'6. Go the gym 2-3 days a week and do 15 mins cardio and 45 minutes weight training. My bust is 34 inches (32D). Waist 27 inches. Hips 37 inches. Thigh 22 inches. My weight is 9 stone 7 (133 pounds) I'm a typical size 10. I do not consider myself fat.
Dependent upon what your body consists of e. g. how much muscle and how much fat etc will depend on how it looks.
I typed in 25% body fat to see if I was (I'm more like 22.5) this was just out of curiosity.
It also pulled up pictures of what 15% body fat looks like on 2 different women. One is a body builder and the other what some would describe as skinny. Basically weight as a number is totally irrelevant without the other information such as body fat %, muscle %, water %.
Also in the UK the average size is a size 16 and height 5'3. I would personally consider this to be fat.
Bearing in mind there are plenty of girls both bigger and smaller than the above as that is the average.
yeah it does depend on the women and how they carry the weight.
I mean I had a friend who was probably in the Large size and she is beautiful and gets a lot of guys. I am in the Medium range but I wear my clothes a certain way that makes me look attractive. Also I think it depends on your height too. You didn't specify that. A person could be like 5'9 and be 120 and that's super skinny.
