Why do I look fatter than I am?

im about 60 kilos ( 132 ) pounds and 170 cm tall ( 5.7 ) but I look fatter that any one in my weight and hight ? why ?

You probably pack on weight in different places than them,or you have more muscle in some spots.
It also probably has a lot to do with your body figure build.

either your shorter then you say or you just have more body fat! if your actually 5.7 and 132 then you should actually be really skinny. muscle is more compact and weighs more so you probably just have less and more fat which weighs less but spreads out and makes you look bigger
