How to ship books in Canada
Pack books so the corners survive, keep each box under the weight where handling charges start, and see why books bill on their weight.
Updated
Short answer. Pack books flat or spine down in a small, strong box, and fill every gap so they can’t slide. Books are dense, so carriers bill them on actual weight: a small moving box of books at 35 lb bills at 35 lb with every carrier. Keep each box under 50 lb to stay clear of heavy-parcel charges.
Packing books
One book. Wrap it in plastic or paper and slip it into a padded mailer, or a book mailer with stiff card inside. Canada Post asks for a rigid material around anything that could bend.
Several books. Lay them flat, or stand them upright on their spines, never on their open edges. Put the heaviest at the bottom, keep similar sizes together, and fill every gap with paper so nothing shifts. UPS asks for a rigid box with its flaps attached and at least 5 cm (2 in) of cushioning around the contents.
A plastic bag around the stack keeps out damp, and a small box beats a big one: books get heavy fast.
Why books bill on weight
U-Haul’s small moving box measures 16⅜ × 12⅝ × 12⅝ in, which carriers round up to 17 × 13 × 13 in. Filled with books, say it weighs 35 lb:

Weight sets the bill at every carrier. The box would have to weigh less than about 17 to 25 lb before its size counted. A single book in a 13 × 10 × 1 in padded mailer bills at about 1 lb.
Keep each box under 50 lb
- UPS and Purolator add extra handling to a box over 50 lb, and FedEx over 55 lb.
- Canada Post asks for an Overweight sticker on anything over 22.7 kg (50 lb).
- U-Haul rates its small box to 65 lb, but the carriers’ lines come sooner.
Books to PO boxes and schools
Many readers in small towns get their mail at a PO box. Canada Post is the only one of the five carriers that delivers there, so pick it for a PO box address. Schools, libraries and offices are business addresses, where carriers deliver on weekdays in business hours.
Is there a cheaper rate for books?
Canada Post’s reduced Library Materials rate is for libraries lending books to other libraries and to readers. Sellers and individuals ship books at the same parcel prices as anything else, so the savings come from the box and the weight: a padded mailer for a single book, a small box for a few, and every box under 50 lb.
Rare and valuable books
Wrap a valuable book in acid-free paper, then bubble wrap, and use two boxes, as UPS recommends for fragile goods. Check the carrier’s cover first. Canada Post caps claims lower for items valued for their rarity, naming comic books, autographed items and antiques among them. Purolator carries collectors’ items at the shipper’s risk, with no claims paid.
