As I have blogged before, the only thing that matters in a rolling paper is the size. The length obviously matters, but papers come also in different widths. You goal is the roll a cigarette of the same diameter regardless of the width of the paper, but it is easier to roll a cigarette with a wide paper. The actual rolling part of making a cigarette is easier with a wide paper, since there is more room for rolling, and hence, in particular, it is easier to make a tight cigarette with a wide paper. The actual rolling part determines the tightness of the cigarette. An experienced roller can make a tight cigarette with a narrow paper, but I recommend wide papers for novice rollers.
The standard short papers are narrow, whereas longer papers and rolls are usually wide. Since long papers are a bit difficult to manipulate, novices should select a roll for their first attempts.
