While the definition of a baker’s gross is somewhat up for debate, we have to think about this question from multiple logical standpoints.
Let’s start with ‘what is a gross?’ and ‘How much is a gross?’. A gross is typically a dozen X a dozen.
So mathematically that would be 12 X 12 which equates to 144. As this is a baker’s gross, one point of view would be that the new mathematic formula is 13 X 13. So the new answer is 169.
Pretty simple, right? Wrong.
A gross might work with a dozen, but bakers famously have their own term for dozen. On top of this, the term ‘short dozen’ might also be involved in the grand total of what a baker’s gross is.
The mathematical formula could be a range of things as bakers could use a short dozen instead which is 10. This means, logically, there are three different formulae to look at.
- A dozen of a bakers dozen : 12 X 13 = 156
- A short dozen of a bakers dozen : 10 X 13 = 130
- A bakers dozen of a bakers dozen : 13 x 13 = 169
Personally, I believe that the most likely answer would be the latter. A baker’s dozen of a baker’s dozen makes the most sense to be the definition of a baker’s gross.
After all, a gross is from the French words Grosse douzaine which translates into ‘large dozen’ so one would assume that a baker’s gross would take the largest possible values which in this situation would be a baker’s dozen.
That makes the likelihood of a baker’s gross being related to a ‘short dozen’ a lot lower which means it is a choice between being either a dozen of a baker’s dozen or a baker’s dozen of a baker’s dozen.
For those of you completely foreign to the idea of bakers having their own measurements, a baker’s dozen is 13.
This is most likely from the 16th century when bakers would sell their products to retailers by the dozen and add an extra product as a representation of the retailer’s profits.
