How do you know what the weight of each book is if you don't have a postage meter?  Do the size of the paper backs, etc and pages have a standard weight?

Thank you

When  you print the wrapper an estimated Media Mail rate is given. Some are correct, some arent. Media Mail is simpler though, since ounces dont matter, only pound increments do. An inexpensive scale is a probably a good investment if you are going to send books regularly though. An inexpensive one will cost you $15 to $20 at any office supply store or mass marketer/big box store. Since Media Mail only covers a one-way journey through the postal system, packages arriving postage due may make for some angry members on the other end. And if the estimated postage is higher than the actual price by just a few cents, the scale will pay for itself within a few years or less.

Most post offices have a scale in the lobby.  And, yes quite a few of the weights in the PBS swap database are wrong.
