Nine of the Roman letters, viz., b,d, E, G, O, P, Q, R and T, when properly made, will occupy one-eighth more in width than in height. Six letters, viz., C, F, J, L S and Z, will occupy the same space from left to right as they do in height. Seven letters, viz., A, K, N, U, V, X and Y, one-sixteenth more in width than in height. H, one-fourth; M, one-third, and W, one half more in width than height. I, two-thirds of its height in width, and occupies one-sixteenth less in width than in height. The circular letters, C, G, 0, Q and S, to appear equal in size with the rest, must be made to project a little above and below the line.
