"What size box do I need?" is the most-asked question we get. The answer almost always depends on three things: the pallet you're going on, the truck you're going in, and the load you're putting inside. Let's walk it.
1 · Start with the pallet.
The North American standard pallet — the GMA — is 48 × 40 inches. That's the dominant footprint for Gaylord boxes too, because the box is sized to ride on the pallet without overhang. If you're not married to GMA, your options open up.
| Pallet | Footprint | Where you'll see it |
|---|---|---|
| GMA standard | 48 × 40 | Almost everything in the US |
| Euro | 47.2 × 31.5 (1200 × 800 mm) | European-headquartered companies |
| Half-pallet | 48 × 20 | Retail displays, DSD |
| Quarter-pallet | 24 × 20 | Display, light retail |
| Industrial custom | 42 × 42, 48 × 48 | Heavy machinery, plant moves |
| Beverage | 45 × 38 | Beverage industry standard |
2 · Then think about height.
Gaylord heights are usually picked to fit a stack pattern in a 53-foot trailer (110 inches inside). Common heights and what they buy you:
- 24" – 30" · light, dense loads. Single-stack two-high in a trailer.
- 31" – 36" · the workhorse. Stacks one-high or two-high depending on load.
- 40" – 48" · large-volume loads. One-high stack only.
- 54" – 60" · custom heavy industrial. Rare but available.
3 · Wall count + ECT decide the strength.
ECT (edge crush test) is the spec that matters for stacking strength. The higher the ECT, the more weight the box can carry without crushing.
| Wall | Typical ECT | Stack load | Best for |
|---|---|---|---|
| Single-wall | 32 – 48 | Up to 200 lbs | Light retail, single-trip |
| Double-wall | 48 – 71 | 200 – 1,200 lbs | General distribution |
| Triple-wall | 700 – 1,300 | 1,200 – 2,800 lbs | Workhorse, multi-trip |
| Quad-wall (4) | 1,300 – 1,800 | 2,800 – 4,000 lbs | Heavy industrial |
| Five-wall | 1,800+ | 4,000+ lbs | Bulk powders, dense ag |
4 · Lids matter more than people think.
An open-top Gaylord loses 40–50% of its stack strength after one trip. A lidded box keeps almost all of it. If you're trying to maximize the number of trips, get the lid. Three common lid styles:
- Telescoping (tray & cover). Full overlap lid that slides over the box top. Best for multi-trip durability.
- Flap-fold lid. Hinged flaps that fold inward. Cheapest, adequate for 1–2 trips.
- Inset (tray-in-tray). Lid that drops inside the box top edge. Common on octagonals.
5 · Common SKUs we ship every week.
| Inside dim (L × W × H) | Outside dim | Wall | ECT | Load (lbs) |
|---|---|---|---|---|
| 46 × 38 × 34 | 48 × 40 × 36 | Triple | 1,100 | 2,200 |
| 46 × 38 × 30 | 48 × 40 × 32 | Double | 700 | 1,200 |
| 46 × 38 × 42 | 48 × 40 × 44 | Triple | 1,300 | 2,500 |
| 46 × 38 × 22 | 48 × 40 × 24 | Triple | 1,100 | 2,000 |
| 38 × 38 × 34 | 40 × 40 × 36 | Triple | 1,100 | 2,000 |
| 43 × 36 × 30 | 45 × 38 × 32 | Triple | 1,200 | 2,100 |
6 · IBC tote sizing.
IBC totes are simpler — there are only two dominant sizes:
| Capacity | Outer (in) | Empty (lbs) | Filled water (lbs) |
|---|---|---|---|
| 275 gal (1,000 L) | 40 × 48 × 46 | ~125 | ~2,400 |
| 330 gal (1,250 L) | 40 × 48 × 53 | ~145 | ~2,900 |
7 · The field tips.
- The outside dimension is what you order. The inside dimension is what your product sees. They differ by ~2 inches per axis on triple-wall.
- If your product is dense (over 30 lb/cubic foot), drop a wall count up. Crushing happens fast at the corners.
- A 48 × 40 × 36 triple is the safest bet you can make if you don't know the spec yet. It works for ~70% of applications.
- Lids cost less than re-shipping a busted load. Get the lid.
- Plastic pallets nest better in racks. Wood pallets are cheaper. Pick your problem.
- Heat-treated (ISPM-15) is required for international shipping. Domestic doesn't need it.
