height is a huge factor in calorie needs. All of the organs, bones, and muscles are larger for a tall person than a short person which is why I hate the general guideline of 1200 calories for everyone. It just doesn't fit for a lot of short people. The largest organ is the skin and tall people have much more skin than a shortie. For many people 5'3" and under the calorie needs would be under 2000 unless they are extremely active. Height is in all of the professional calculations for estimated calorie needs.
As a general rule of thumb, losing 2 pounds a week is a healthy rate of weight loss. If you aren't losing any weight then you need to cut back on calories or you have reached your weight. Really make sure you count everything you put in your mouth. It is easy to forget the salad dressing or the mayo on the sandwich. Measure your food for at least a couple of weeks if the calories still seem way off. People almost always under estimate when not measuring anything, there have been studies on this.
