I use ready rolled sheets of puff pastry to make these apple turnovers, and have found the sheets vary in size according to the brand. Generally though, your turnovers should be approximately 8cm x 10cm. Make sure you use butter puff pastry. I outline my reasons why here. I don’t sweeten my applesauce, as I find it sweet enough for my taste. If you want the sauce a little sweeter, just stir a teaspoon or two of maple syrup in with the cinnamon.
