One the 12" issue:
Of course you're going to charge more for 12" wood than for 16" wood. Don't give it another thought.
On the cord issue
I've found there is some discrepancy between what people say on the internet and reality. In reality, most people who sell wood for a living do not stack to measure wood. Some professional sellers actually have wooden or steel frames for this purpose; however, most sellers fill a specific truck or trailer to a certain level because they know through trial an error that it will stack up to a certain cord amount.
Many people on the internet will argue that the cord is the only way to measure wood. The concept of the cord as a universal measurement requires:
(1) That the length of the wood is evenly divisible by 48 inches; the wood must be cut to either 24”, 16” or 12”
Nope: nothing in the definition requires it be stacked to 4x4x8. It can be stackec in one rick 16" X 4' x 24' and be a cord. Or 12" x 4' x 32'. It can even be cut to and odd lenght such as 37" and as long as it measures out to 128 cu ft it is a cord no matter how it is stacked.
(2) The wood is cut so perfectly that it will actually stack up to 48”. In other words, if I am cutting 16” wood and my wood varies in length from 15 to 17 inches, my stack will have air spaces on its face between rows and probably stick out to 50” and not 48”.
The definition includeds "tightly ranked (old language) which was sometimes interpreted as "tight enough a mouse can run through it but the cat can't follow. The definition of course allows variation and eveyone understands that.
(3) Even if my wood is perfectly cut (meaning I used a processor or tape measured every piece), I would have to stack every cord into a frame, which most high volume sellers simply do not due.
No again. All it requires is taht when you deliver a cord of wood if the customer stacks it, it will measure 128 cu ft. Nothing says _you_ have to stack it.
In summary, selling by the rick or face cord is probably just as acceptable as anything.
Honesty on the part of the seller is the key. It is okay as long as your volumes agree with whatever the _local_ understanding of what rick or face cord is. Just please use cords or fractions on forums such as this so everyone knows what you are talking about.

First of all, guys that sell hundreds or thousands of cords per year do not have time to do what is depicted in the picture. Even the guy with the perfectly cut 16” wood who stacks every cord into a wood frame before putting it onto a truck needs to be honest. Even he could deliberately sell 5% or 10% less than he is supposed to by not putting it all on.
