This is a full size pastry mat which is surprisingly harder to find as most tend to be half-sheet sized. It has both metric and imperial measurments as well as extremely handy conversions printed on it. This was immensely helpful for me when trying out a British recipe but my measuring cups and spoons are all American sizing. I took off a star because the mat is thinner than others I have used and I found that some baked goods would stick to it a little.
