Question:
What does point, as in 10-point or 12-point stock, refer to?

Answer:
When referencing paper, point refers to a unit of thickness equaling 1/1000 inch. So the thickness of a 10-pt paper is 10/1000 (.010) inch. In the United States, cover paper is often referred to in points, such as 10 point or 12 point. The point is usually considered equivalent to the weight in cover stocks. For instance, an 80# cover would be referred to as an 8 pt., a 100# cover equivalent to 10 pt., etc.
