Petites, help me please!

I'm curious how much other short girls maintain on. I'm just under 5'1" (that extra inch is very important!) and don't really know how many calories I need to maintain. I'm also 15. I've heard many times that teenagers need 2000+ calories to maintain their weight, but I seem to maintain at about 1600. Is my  body used to eating not enough calories, or do I just need less because I'm short?
Oh, I suppose I should say that I weigh 100 pounds and try to run/walk almost every day for 20-40 minutes. Also, I am definitely done growing-- I've been the same height since I was 11! (I went through puberty very early.)
Any comments or advice would be very helpful. Thanks!

I'm a couple inches shorter than you, and I maintain at around 1400-1500, so around 1600 sounds reasonable to me! If you're running every day, however, it might be a good idea to bump it up a few hundred though, definitely!

Im not sure how much it takes for me to maintain. but i dont want to maintain! i want to lose lol. im barely 5'1 and a 140 pounds but for some reason it doesnt seem to really show on me i guess im just curvy but i still would like to lose some. i dont think it takes less for us because we're short, maybe your metabolism is just slower than most ppl's.

Shorter people do usually tend to need less calories than those who are taller but since you're under 21 and also quite active, I'd suggest using http://www.bcm.edu/cnrc/bodycomp/bmiz2.html and going by the moderately active or very active guides for maintaining.

The reason you seem to be maintaining on less is probably because your metabolism has slowed down from a reduced calorie intake. It'd be to your benefit to increase your calories to the recommended amount by that site. Even though you may be done physically growing, your body is still growing even if you can't see it (for example, your brain still develops well into your twenties). Plus, who doesn't want to eat a bit more :p

Look over at your burn meter, that's how many calories you need a day to maintain. c:

I'm 5'2 and just switched to maintenance from gaining; I maintain on 1500-1800, as above. I'm older than you though, so you might need more than this.

i'm 4'11 and maintain on 2000-2100. but i think time will catch up to me and it will be more like 1800-1900.
