Postal Rate for Mailing Books: USPS Media Mail Rates and Limits

Mailing a book through USPS Media Mail costs $4.47 for the first pound and $0.75 for each additional pound, up to 70 pounds. Distance doesn’t change the price. A one-pound paperback ships coast to coast for the same $4.47 you’d pay to send it across town, which is why Media Mail rates for books through USPS remain the cheapest way to move printed material domestically.

2026 Media Mail Rates by Weight

As of January 18, 2026, the retail price schedule looks like this:¹

1 lb: $4.47
2 lbs: $5.22
3 lbs: $5.97
4 lbs: $6.72
5 lbs: $7.47
6 lbs: $8.22
7 lbs: $8.97
8 lbs: $9.72
9 lbs: $10.47
10 lbs: $11.22

The formula holds all the way to the 70-pound ceiling, which tops out at $56.22. Any fraction of a pound rounds up, so a 3.2-pound package pays the 4-pound rate of $6.72. Weigh accurately before you buy postage.

One quirk worth knowing: unlike most USPS services, Media Mail retail and commercial rates are identical. Buying postage online or through a third-party platform won’t lower the price on this service the way it does for Ground Advantage or Priority Mail.

What You Can Ship at the Media Mail Rate

Media Mail is restricted to items USPS considers educational or informational. Books qualify as long as they contain at least eight printed pages of reading matter and carry no advertising beyond small announcements of other books. Hardcover, paperback, and loose-leaf bound books all count, and you can include the binder when the pages form a book.²

Beyond books, Media Mail covers sound and video recordings (CDs, DVDs, Blu-rays, vinyl), printed sheet music, playscripts and manuscripts, educational reference charts, computer-readable media with prerecorded content, 16mm or narrower film, printed test materials, and medical information in loose-leaf form distributed to medical professionals and students.³

The single biggest disqualifier is advertising. Comic books, for instance, don’t qualify because they typically carry ad pages.⁴ Magazines and periodicals with ads, video games, blank recordable media, empty computer drives, and ordinary letters are all excluded. You also can’t tuck non-media items into the box alongside qualifying books. The only permitted enclosure is a bill for the product or a brief personal note.³

How Media Mail Compares on Cost and Speed

The savings show up immediately against USPS Ground Advantage, which starts at $8.85 for a one-pound package and climbs to $11.95 depending on distance. That’s roughly double the Media Mail rate for the same weight, and the gap widens as packages get heavier because Ground Advantage prices vary by both weight and zone while Media Mail stays flat.¹

The trade-off is delivery time. Ground Advantage arrives in 2 to 5 days. Media Mail runs 2 to 8 days.⁵ For a birthday gift or textbooks a student needs Monday, that window is risky. For a used-book sale or anything without a hard deadline, the slower schedule rarely matters.

Priority Mail Flat Rate is worth a look only for very heavy loads on tight timelines. A Medium Flat Rate Box costs $22.95 and holds up to 20 pounds; Media Mail at 20 pounds runs $18.72, so the flat rate makes sense only when the 1-to-3-day delivery is worth the premium.¹

Size and Weight Limits

Media Mail has no minimum weight and a 70-pound maximum.³ The combined length plus girth of the package cannot exceed 108 inches. Measure the longest side, then wrap a tape around the thickest part and add the two numbers. A standard moving box packed with books will almost always fit within this limit.⁶

Preparing and Sending the Package

Use a sturdy box or padded mailer. Books are heavy and their corners can punch through weak cardboard. Fill any empty space with bubble wrap or crumpled paper so nothing shifts in transit, and seal every seam with strong packing tape.

The package must show the recipient’s full delivery address and your return address on the same surface, along with the postage. USPS requires a return address on all Package Services mail, including Media Mail.⁷ Every Media Mail piece also has to be marked “Media Mail” near the postage area. Labels printed through USPS.com or shipping platforms add this automatically, and counter clerks apply it when you pay in person.⁸

Small prepaid packages can go into a USPS collection box. Larger shipments go to the counter. Every Media Mail package includes USPS Tracking at no extra charge.⁵

Inspections and Postage Due

Media Mail is not sealed against postal inspection. USPS reserves the right to open and examine any package to confirm the contents qualify, and postal workers do check when something feels heavier or oddly shaped for its declared contents.⁹

If an inspection turns up ineligible items, USPS reclassifies the package at the correct higher rate. The extra postage can be billed to the recipient as postage due, or USPS may come back to the sender for payment.¹⁰ Don’t slip a card or a small gift in with the books.

Insurance for Valuable Books

Media Mail includes no built-in insurance. If you’re shipping something rare or expensive, add merchandise insurance at these 2026 rates:¹

Up to $50: $2.70
$50.01–$100: $3.40
$100.01–$200: $4.40
$200.01–$300: $4.45
$300.01–$400: $5.95
$400.01–$500: $7.45
$500.01–$600: $8.95
$600.01–$5,000: $8.95 plus $1.50 per $100 (or fraction) over $600

Coverage tops out at $5,000. For a $500 first edition, $7.45 is a small fraction of what a lost package would cost you.

Two Boundaries Worth Knowing

Media Mail is domestic only. It cannot be used to send books outside the United States. For international book shipments, First-Class Package International Service handles packages up to 4 pounds with pricing that varies by destination country, and Priority Mail International covers heavier loads. Neither comes close to Media Mail’s domestic pricing.¹¹

If you’re shipping on behalf of a school, library, museum, or qualifying nonprofit, Library Mail is cheaper still, starting at $4.25 for the first pound in 2026 and staying below Media Mail at every weight.¹ Individuals can’t use it. Shipments must be sent between or to qualifying organizations, and the same content rules and inspection risk apply.⁹
