A Gaylord box has a standard 48 × 40 in (122 × 102 cm) base matching a GMA pallet, with heights of 24–48 in. Triple-wall construction is rated ~1,100–1,200 lb; quad-wall reaches 2,000 lb; five-wall reaches 2,500–3,000 lb.
A Gaylord box is specified by outside Length × Width × Height; the 48 × 40 in base is fixed to match a standard pallet, so height is the main variable between models.

A spec table only helps if the buyer reads it. Many don't — shoppers routinely try to judge a product's size straight from the images, and wrong size or fit is the most-cited reason things get returned. The fix is to mark the real dimensions on the photo itself, where the buyer is already looking.
SizeMarker snaps dimension lines to the gaylord box's edges and exports at Amazon or Alibaba size, so the measurement is accurate and legible — not a guess typed over the picture. That answers the size question up front and cuts pre-sale questions and size-driven returns.

Gaylord boxes share a 48 × 40 in (122 × 102 cm) base sized to match a GMA pallet. Height commonly runs 24–48 in: 36 in is cited most often as "standard," while 40 in is the top seller in Verde Trader's 2026 order data.
It depends on wall count: roughly 500 lb for double-wall, up to 1,200 lb for triple-wall (Uline's 48 × 40 in line is rated 1,100 lb), 2,000 lb for quad-wall, and 2,500–3,000 lb for five-wall construction.
The standard 48 × 40 in (122 × 102 cm) GMA pallet — the Gaylord base is built to that exact footprint, per pallet manufacturer PalletOne and the ISO 6780 pallet standard.
About 20–26 assembled boxes single-stacked on pallets, varying with height, or 200–400+ when shipped flat/knocked-down before assembly, per Repackify's freight data.
Wall count is the number of corrugated layers: double-wall (2 layers, ~500 lb) suits light loads, triple-wall (3 layers, ~1,100–1,200 lb) is the general-purpose default, and four- or five-wall (2,000 lb to 3,000 lb) handles heavy, dense, or roughly handled materials.
