About Palletly
Palletly is a free set of pallet, CBM, dimensional-weight and container-load calculators built on permanent geometry and physics, no signups, no stale rate tables.
What Palletly is
Palletly is a focused set of free calculators for the dimensional side of freight: how many boxes fit on a pallet, how many pallets fit in a container or trailer, the cubic meters (CBM) of a shipment, and the dimensional or volumetric weight a carrier would bill. Each tool does one job, shows its working, and runs entirely in your browser.
We built it because most online freight tools bury a simple calculation inside a quote form, an account wall or an advert for a forwarder. The math here, length times width times height, floor patterns, volumetric divisors, does not require any of that.
What we deliberately leave out
We only publish numbers that stay true. That means we cover geometry (volume, fit, layers, stack height) and the fixed billing conventions carriers use to derive weight from volume. We do not quote shipping cost, rates, surcharges, customs, duty, tax or insurance, because those change constantly and depend on your contract. For anything that drives a booking, your carrier is the source of truth.
One area deserves a specific note: freight class. Since July 2025 the NMFC system is largely density-based and is revised periodically. We will estimate a class from your density so you can plan, but we always tell you to verify the current classification with your carrier or NMFTA, and we never publish a static per-commodity code table.
How the site is organised
| Family | What it answers | Start here |
|---|---|---|
| Pallet | Boxes, cases or cartons per pallet; TI x HI; gross weight | Pallet calculator |
| CBM & volume | Cubic meters and cubic feet of a box or mixed load | CBM calculator |
| Dimensional weight | Volumetric and chargeable weight by carrier divisor | Dimensional weight calculator |
| Container & truck | Pallets or boxes in a 20ft, 40ft or trailer | Container load calculator |
If you want to see the exact formula behind any of these, read how we calculate. It lists each formula, a worked example, and the point at which the math stops being exact, chiefly single-orientation packing and the density-only class estimate.
Accuracy and feedback
We use published pallet footprints, container interior dimensions and carrier divisors, and we show our arithmetic so you can check it. No tool is a substitute for the party that will physically move your freight; verify load plans and classifications before you commit. If you spot a wrong figure or a formula you think is off, tell us, corrections are welcome on the contact page.
