In the chart below, the inch measurements are the size of the sweater you would want, which is usually a few inches more than your own chest size, depending on how close or loose a fit you like.

One way to gauge the fit you like is by measuring a sweater which fits you the way you like.  Lay it flat, measure it across the chest from underarm to underarm, and double that measurement (to get the sweater circumference).
