Am I too short and too fat for my age???

You're never too short. Your height is just your height. wewe were born to be that tall, and there's nothing wrong with how short/tall wewe are.
And no, I don't think you're too fat at all. In case wewe do start gaining weight, though; some girls around twelve/thirteen/fourteen start getting chubbier, and then you'll go back to normal in a mwaka au two. But it doesn't sound like wewe have that problem.

Baby girl, your just fine. When girls hit puberty, they gain a little weight but wewe lose it right when puberty is over. And as for being short. wewe are perfect! When I was your age, i was 5'1. wewe are fine. Your body will naturally have a growth spurt later in life. And even if wewe don't, your perfect! Dont worry about yourself. Just stay healthy, and wewe will be good! Worry about what fits your age. You'll have time to worry about height and weight for a long time when your older. Everything is fine! Dont try too hard to fit in with your peers. It's all good!

dude im 15 years old and im 5'4'.

No, you're not.
Your BMI is 21.5, which is normal.
The taller wewe grow, the slimmer wewe will get.
Trust me, I used to weigh 110 lbs and was 4' 10", then I started to gain weight zaidi slowly and grew a lot taller.
My current weight is 121lbs and my current height is 5' 6"

i think u are perfect according to your age and with age your height will grow too n your weight is perfect so dont worry about this :)

i'm to tall and to fat. Don't worry about it :)

Your not fat, I weigh 140 pounds and I'm 19.
You're fine.
