About once a week we receive a phone call or email asking us to describe the difference in pecan sizes. In fact, I had such a conversation today with a new customer. We love to help educate people on the various options that are available. When you are a newbie to any industry it helps to have some clarity offered on basic terminologies. Asking about an overview of pecan sizes is a great question and one that is best explained with a combination of pictures and words.
