You are doing integer division:

double ratio = 4 / 3; // evaluates to 1

This won't give you the value you are looking for because the decimal point is being truncated, thus evaluating to 1 instead of 1.333. At least one of the operands needs to be a double:

double ratio = 4.0 / 3.0; // evaluates to 1.333

Same goes for Height. Change the 4 to 4.0.
