People come in a variety of sizes so do guitars. I suggest finding the right size and shape of guitar for you. Scale length alters how far you need to reach out along the neck. Body shape makes a difference. A jumbo acoustic guitar may be too large for you if you are 4ft 2''. For acoustic guitars the distance from where the elbow reaches over the body to the sound hole is critical. If you struggle to reach over. Wrong size. Is it balanced? Guitar should not be neck heavy. General comfort. You are going to spend hours sitting with this on your thigh or standing. Make sure it fits.
