What is the average height and weight of models?

Answer 1

That depends on what type of modeling you are talking about.

Fashion and runway models are typically 5'10" and between 100-120 lbs.

Commercial/print models are typically 5'7" and between 100-125 lbs.

Answer 2

As you probably know, fashion models are skinny and tall. Many of the agencies use the 86-60-86 measurements. This means that the model should be 86 cm around the bust and hips and 60 cm around the waist. Of course this is give or take a couple of cm. Many agencies tell you that you have to be at least 5'9" (just about 175 cm tall). You should also have good bone structure (especially cheekbones).
