These templates are preset for the two sizes of paper A4 and US Letter. The only differences are in the margin settings and are arranged in both cases so that the active area in the centre of the page is 6 inches by 9 inches. So if you use the template appropriate to your paper size you should get exactly the same quantity of script on the page in both cases.

For US Letter the left margin is 1.5 inches and the top, right and bottom margins are 1 inch.

For A4 the Left margin is 1.5 inches, the top margin is 1.3 inches, the bottom margin is 1.4" and the right margin is 0.8"
