January 7, 200917 yr I really don't measure anymore but in the beginning I used both. For meat, fruit etc. I used the oz. measurement (one ounce the size of 2 stacked dice, three ounces size of deck of cards...) For cooked veggies and other sides I measured with a masuring cup or spoon.
I was told 4-6 ounces and about 1/4 to 1/2 cup. How do you measure?
