Our "Small" jars are stamped 1/8 ounce on the bottom. And indeed, they are 1/8 ounce *if* you only fill them to the beginning of the very first fill line of the neck. But if you fill them to *almost* the top, they are 1/4 ounce, and if you fill them to the very brim, they are very slightly over 1/4 ounce.
We typically fill them to where they are about 1/5 ounce.
So, how big should we call the jars?
We skirted the problem completely, simply by calling the jars "Small".
