Most people would say that they get about 1/4 of a cup of juice from an orange.  This is typically true, but there are a lot of variables that can affect how much juice you get from an orange.  The size and type of orange, the ripeness, and even the way you cut it all play a role in how much juice you get. One thing to keep in mind is that oranges vary in size. A small Satsuma orange might only yield 1 or 2 tablespoons of juice, while a larger Navel orange could give you 1/2 a cup or more.  The juiciness of orange also depends on its ripeness. The riper the orange, the more juice it will have.
