Freight Class for Books
Books are dense and ship at a low freight class — usually 55 to 77.5 when boxed and palletized.
What is the freight class for books?
Paper is heavy for its volume, so tightly packed cartons of books rate among the lower classes. The main risk is over-packing cartons past safe handling weight; otherwise books are inexpensive to ship by density.
Because freight class is density-driven, there isn’t a single fixed number for books — class 55–77.5 is the common range. Run your actual dimensions and weight below to pin it down.
Deceptively heavy paper
Books look like light freight and ship like dense freight. Paper is heavy for its volume, and a tightly-packed carton of books has almost no wasted space between them, so palletized books rate class 55–70 — down with building materials and canned goods rather than the light retail classes their category might suggest. A skid of textbooks is genuinely heavy, and the surprise on a books shipment is usually the weight, not the cube.
The spread is narrow and driven by binding and pack. Dense hardcovers and textbooks pack the heaviest and rate class 55–65; paperbacks are a bit lighter and rate toward class 70; catalogs and printed matter behave like the paper they're made of. Because books are so dense, the real hazard isn't the class — it's over-packing a carton past what a person can safely lift, which turns a cheap shipment into a handling and injury problem.
Books freight class: worked examples
Density is weight ÷ volume (cubic feet = L × W × H in inches ÷ 1,728). Here is how typical books shipments measure out:
Cartons of books, palletized — class 65
Boxed books on a 48" × 40" pallet, 44" high, 1,300 lb.
48 × 40 × 44 = 84,480 in³ ÷ 1,728 = 48.9 ft³. Density = 1,300 lb ÷ 48.9 ft³.
26.6 lb/ft³ → class 65 — palletized books are dense, cheap-rating freight.
A single carton of hardcovers — class 65
One right-sized carton of hardcover books, 18" × 12" × 14", 45 lb.
18 × 12 × 14 = 3,024 in³ ÷ 1,728 = 1.75 ft³. Density = 45 lb ÷ 1.75 ft³.
25.7 lb/ft³ → class 65 — even one carton is dense; note the weight for safe handling.
Palletized paperbacks — class 70
Lighter paperback cartons on a 48" × 40" pallet, 48" high, 800 lb.
48 × 40 × 48 = 92,160 in³ ÷ 1,728 = 53.3 ft³. Density = 800 lb ÷ 53.3 ft³.
15.0 lb/ft³ → class 70 — lighter paperbacks rate the top of the book range.
Right-size the carton, build to weight
The discipline with books is carton weight, not density optimization — the density takes care of itself. Keep individual cartons to a safely-liftable weight (many shippers cap book cartons well below what the box could physically hold), because a 90-pound carton of textbooks is a claim and an injury waiting to happen. Full but not overloaded cartons, stacked square and banded on a weight-rated pallet, give you the cheap class without the handling risk.
Build the pallet to its weight limit rather than a height target — books get heavy fast, so a pallet maxes out low with space to spare, and stacking taller only risks crushing the bottom cartons. Keep dense hardcovers and lighter paperbacks reasonably sorted if a shipment mixes them, and protect against moisture, since paper absorbs humidity and gains weight. Run the real pallet weight through the calculator; books almost always weigh out before they fill any space.
What affects books freight class

How freight class is calculated (density scale)
Freight class is set by density = weight (lb) ÷ volume (ft³). Higher density → lower class → typically lower cost. Volume here is L × W × H × quantity.
| Density (lb/ft³) | Class |
|---|---|
| 50+ | 50 |
| 35 – 50 | 55 |
| 30 – 35 | 60 |
| 22.5 – 30 | 65 |
| 15 – 22.5 | 70 |
| 13.5 – 15 | 77.5 |

Frequently asked questions
What freight class is books?
Books typically ships at freight class 55–77.5. The exact class is set by density — weight divided by volume — so packaging and dimensions can move it within that range.
What affects the freight class of books?
The main factors are carton fill and weight, hardcover vs. paperback, palletization, carton size limits. Denser, tightly packed loads rate a lower class and cost less to ship.
How do I find the exact freight class for books?
Measure your shipment and divide weight by volume to get density, then match it to the NMFC scale — the calculator above does this. Confirm the final class and NMFC item number with your carrier before booking.
What freight class are books?
Palletized hardcovers and textbooks measure ~25–27 lb/ft³ → class 55–65; lighter paperbacks rate toward class 70. Books are dense, cheap-rating freight — the surprise is usually the weight, not the class.
Why are books such a cheap freight class if they seem light?
Paper is heavy for its volume and books pack with almost no space between them, so a carton is very dense. That earns class 55–70, down with dense goods — the individual book feels light, but a carton or pallet is genuinely heavy.
How should I pack books for shipping?
Keep individual cartons to a safely-liftable weight (don't fill a big box to the brim with textbooks), stack square and banded on a weight-rated pallet, and build to the weight limit rather than height. Protect against moisture, which adds weight and damages paper.
