About PalletSizes.com: Neutral Pallet Reference

PalletSizes.com is a reference for pallet sizes and for working out how much fits on a pallet, in a trailer or in a container. It does not sell pallets, take quotes or give freight advice.

What the site is for

Pallet size answers are usually buried in a seller’s catalogue or a broker’s quote form. This site puts the sizes in a table in inches, millimetres and feet, shows where each row comes from, and adds calculators whose method is written out on the page.

How pages are checked

Every figure on a page is either given with its source or computed by a calculator whose method is shown. If a source could not be read, the page says so or leaves the figure out.
Pages show the date they were last updated.
Calculators run in your browser. Size tables and worked examples on the pages are generated from the same data and code as the calculators, so they cannot disagree. The calculators have automated tests.
Calculators are estimates with stated limits. Packing results are geometric, not load plans. The freight class calculator gives a density-only estimate.

Pallet size rows: Wikipedia, “Pallet”. Wikipedia text is available under the Creative Commons Attribution-ShareAlike 4.0 licence. This site takes dimensions (facts) from it and does not copy its text. ISO 6780 is paywalled and was not read; the pages repeat only that Wikipedia lists a size as an ISO 6780 size.
Freight class density scale: dtsone.com, July 2025 NMFC changes, a secondary source, read on 2026-11-09 and not yet checked against the NMFTA publication. Effective date and docket: NMFTA and Old Dominion Freight Line. While the scale is unverified, the calculator and chart show a notice saying so.
Trailer interior sizes: ATS and Hale Trailer.
Unit definitions: NIST SP 811.
No third-party datasets are bundled with the site.

Who runs it

The site is edited by the PalletSizes.com editorial team. The owner also runs a-w-b.com, an air freight site. This site links to it only from the air cargo pallet guide, and labels the link there.
