There is no category as such , Some guys would Think a girl is fat that you or I would think were Thin , Fat is somthing each person categorizes people in in there own way but that's not the answer you want is it I will give some exsamples

found that on google she's not that great but its the body you want to see, just a little bit but not fat , but to be honest if a girl was realy good looking and had a liitle bit to hold on to its all good , I mean in preference I'm not too into girls like that when I think of a perfect body but then again there is more in life then a perfect body if you get what I mean.
I would consider her curvy or thick because she has an hourglass shape. She wouldn't look right skinny, she has a thicker build but no where near fat.
A specific weight can't really be given, it depends on the build the girl has, some can pull off carrying a little more weight than others, even if they're the same height.
If you want a general idea, when the fat tissue starts to flow over your pants, that's when you know you're too big.
Check her BMI, or Body Mass Index. You can do it online, just google it. You just have to type in height and weight and it will give you your body mass index, which is (I think) what portion of your body is fat. There should also be a chart that tells the numbers for underweight, healthy, overweight, obese, etc. So just look to see what range her BMI fits into, and that should tell you if she is overweight or not.
It depends on how you look and carry it. Some girls can only gain 20 pounds before they start looking fat, some girls can carry more.
Maybe she's just chubby? I think of chubby being between soft and fat.
