With the numerous kinds and sizes of paper at our disposal in these days, we have no excuse for not choosing paper suited to our various needs. White unruled paper is always in good taste for all forms of correspondence. Four-page paper looks better for letters of friendship than the two-page form used in business.

Naturally we should try to adapt the size to the length of communication, with a view to making the letter pleasing in appearance and easy to read. Little thought is necessary to decide whether to use ordinary business paper, some eight inches by ten in size, or note paper, for inviting a friend to lunch.

Business correspondence should be written on one side of the paper only.
