Which paper stock you choose when printing your book can have a huge impact on your print pricing. Coated or uncoated? Glossy finish, matte finish, or standard offset? What’s the opacity? What’s the weight? The answer to these questions will determine your paper pricing.

Book paper weights are different than the paper weight measurements you will see in an office supply store. A 20# bond that you would find at Staples is similar to a 50# offset at a book printer. A 24# bond is similar to 60# offset, 28# is similar to 70# offset, etc.

That 50# offset paper proves to be fine for many books. If your book has no or few images and no color inside, there is little reason to print on a much thicker paper. Save your money. You may want to check the pricing for 60# offset, but I usually don’t recommend printing on paper much thicker than that for most novels, etc.

Don’t assume that the 20# bond paper you saw at Office Depot is going to be identical to the 50# offset paper you asked your printer to use. It won’t be. Different paper manufacturers produce their papers with different brightness, different opacity, etc. So always ask for paper samples from your printer.

Now let’s assume your book is not as simple as a novel or a book with just black text. Maybe your book needs to be printed in full color. If that’s the case, you’ll want to use a paper stock that highlights the color better than a typical offset sheet. Glossy paper will usually do the trick.

Most full color books are printed overseas, where a different standard of paper measurement is used - grams per square meter (gsm). To calculate gsm, multiply the offset weight by approximately 1.5. So an 80# gloss sheet in the U.S. would be the same as a 120 gsm sheet overseas. You’ll definitely want a thicker paper stock for your color book versus a black & white book.

I can’t say it often enough: No matter which paper stock you think you want, ask your printer for some samples first.

Paperback covers overseas are usually printed using 250 gsm or 300 gsm cover stock. In the U.S. that translates to a 10 pt. C1S or 12 pt. C1S sheet. Also be sure to add gloss lamination to give your cover that extra pop!
