Billheads and statements should correspond in style to that of letterheads and other forms of stationery, and in changing the design it must not be forgotten that these other forms should also be altered to harmonize. The paper should be of the same finish and color, and the main features of type arrangement similar. The type-face must be the same on all.

The standard sizes of billheads for commercial purposes are:

8½ ×  5½ inches, 8 out of a sheet 17 × 22.

8½ ×  7  inches, 8 out of a sheet 17 × 28.

8½ ×  9⅓ inches, 6 out of a sheet 17 × 28.

8½ × 14  inches, 4 out of a sheet 17 × 28.

Professional billheads are usually an inch or two smaller than the smallest size of commercial billheads.

There is a variety of sizes in statements. Popular sizes are those cut out of folio (17 × 22 inches), which then measure 5½ × 5⅝ inches, and 5½ × 8½ inches.
