Paper Types

Did You Know? The basis weight of a paper (ie. "60lbs" or sometimes listed as "60#") is the designated fixed weight of 500 sheets in that paper's basic sheet size. But the "basic sheet size" is not the same for all types of paper and some types of paper come in a variety of sheet sizes! Even if the numbers look like they mean the same thing, always ask your printer to recommend a stock if you're not sure.

Finished Trim Sizes

Books fall into three pricing groups based on size thresholds. Once any threshold is exceeded, the pricing for the book goes into the next largest book group (width in inches x height in inches).

Please note: While pricing is based on the size groups, the exact trim size is required for accurate quotes and printing.

4" x 6" but smaller than (or equal to) 5 1/4" x 8 1/4"
Larger than 5 1/4" x 8 1/4" but smaller than (or equal to) 6" x 9"
Larger than 6" x 9" but smaller than (or equal to) 8 1/2" x 11"

Laminated Covers

Printorium Bookworks offers both gloss and matte laminates for book covers. Used as both a protector and an enhancer, it is a highly recommended option. Before deciding if it's necessary for your printing, consider how often the book will be handled as laminate adds both durability and longevity to the cover.
