Go to the CDC and look at the growth charts. There is one that has height on one axis and weight on the other. I would say that chart is more illuminating than the weight of strangers' kids. It is also important to track your child's height and weight over time. If they stray from their normal curve, you'll want to find out why. In other words, a kid who has always been 75th percentile height and 50th percentile weight, should be checked out if one or both of those change significantly.
my 6 year old boy is 49" and 48 lbs. He is in the 10th% of bmi so I think your dd must be lower too
