You should keep your DR in plotting sheets.
The sheet intent to represent a chart, with latitude and longitudes and a
compass rose. Now, depending upon the latitude you''ll be navigating, the drawn space between meridians or paralells will be modified, since you will need to continue to represent in the scale nautic miles
You can get those at any Marine shop, which probably are twice as large as a letter page, o print out from any source from Internet.
You might we willing to look into this page, which explains in more detail the plotting sheet story, and also download the sheet.
This sheet is prepared and published by the US Defense Mapping Agency, normally comes in a pad of 100

Some other links to free plotting sheets are
1. http://www.reedsalmanac.com/pdf/ups.pdf
which is a A free PDF Universal plotting sheet in 8.5" x 11" format
2. ftp://ftp.wa6pby.com/nav/posplot.zip
A program that generates and prints plotting sheets for your selected latitude (8.5 x 11 inches). You need to calculate for each latitude a new plotting sheet. This is not my favourite.
