Having worked in the industry for over 10 years, I can give the following insight. A persons' height is not the deciding factor but rather their hip to shoulder back measurement. You can be a tall person with long limbs but short torso for example. Any good outdoor show should be able to assist you. I am 6' 3" for example with a long back, I use Extended Length back packs for my frame. I have friends the same height as me that find they can use a pack designated for a woman that fits perfectly. Get fit for your pack by a professional that can give you tips and education in latest innovations within the industry, Good Luck Jimm.
