The most commonly selected trim sizes are 5 x 8 inches and 6 x 9 inches. However, we offer trim sizes that range from 4 x 6 inches to as large as 8.5 x 11 inches are also available. All sizes are available with perfect-bound (paperback) binding, while select trim sizes are also offered in hardcover format, either with or without a dust jacket, and case laminate (like text books) are also available.
