This "ideal bundle size" has been tossed around for dozens of posts. Mine has to be larger in order to be competitive with the supermarkets, convenience stores, etc. And, my price strategy has to promote multiple unit purchases, so that's another consideration. The size of the splits and logs mixed in and the density of the wood you are using figures in as well.
Most agree that splitting the logs down further is desirable for bundles because people like campfires to light more rapidly and burn faster. They also tend to like lower density wood that's lighter to carry and that burns faster also. So, my solution was to use 7 to 9 log bundles of cottonwood, soft maple, willow, poplar, and linden (basswood). I mix in some elm and ash now and then. This works for me, but local conditions and supply are going to influence everything, not to mention the competition from the high-volume dealers.
