First, let’s bust a myth: there’s no single, universal answer. The number of stamps on a book depends on weight and destination—not the number of pages or how much you paid for it. A thin paperback might need just one standard “Forever” stamp. A hefty hardcover? That beast could require three or four, maybe more.
Here’s the dirty little secret: postage rates are a moving target. The U.S. Postal Service updates them every year. But the good news? You don’t need a postage degree. You just need a kitchen scale—or a clever trick using your own two hands.
Weighing Your Way to Success
Grab that book, step on your bathroom scale while holding it, then subtract your own weight. (Yes, I’m serious—it works for a rough estimate.) For precision, a $10 food scale is a game-changer. A typical 300-page trade paperback weighs about 10 to 12 ounces. That’s two or three Forever stamps for domestic shipping.
But what if the book is going to Canada or Japan? International rates are higher—often requiring five to seven Global Forever stamps. Don’t panic! The USPS website has a handy “Postage Price Calculator.” Type in the weight and zip code, and it tells you exactly how much you owe. It’s like GPS for your mailbox.
