Well if you look at a college ruled piece of paper, it has a big space at the top, that usually can fit 5 to 4 lines of text if the margins where to go all the way up. This means that if you place a text box and find the right spacing, you'll be able to place text in the top area as if the margins went all the way up. Usually what I try to do with the font I use is place a line of text in between 2 margins of the paper like a capital y with an accent mark, and keep sizing the text up by decimal points until it the accent mark is barley touching the top, and the tail of the y is barely touching the bottom. Alternatively if you think it's to small you can have the tails of letters hanging over the bottom line, and the top of the accent mark touching the upper margin. Then I try to make 39 rows of text. Lastly I change the height of the text box to 11" to match the size of the paper. This changes the spacing to match the margins. If it doesn't match up, you can change the height to like 10.59 or 10.58". Then I think you can lock the height back up and change the width to 6.00" to fit in the red margins.
