As I mentioned in the Ingredient notes section, I used three 6 ounce cans of Pillsbury Buttermilk Biscuits with "Flaky Layers." Each can has 5 biscuits, so each biscuit is about 1.2 ounces (34 g). So, if you find another brand of biscuit dough with similar proportions, even if there are more or less biscuits in each can, you are all set. (Just be sure to buy enough cans to equal 15 biscuits total!) Otherwise, you can still use another brand of canned biscuit that is larger or smaller than 1.2 ounces (34 g) each, but you will need to adjust the cooking time, either up or down a few minutes, depending on the size. To be extra sure, you can always bake 1 turnover first as a test to get the timing right before baking the whole batch. And of course, if you are making larger turnovers, you will not be able to make as many unless you scale up the filling as well.
