What is the difference between T11, T12, and EUR pallets?

T11 (1100×1100mm) is the Korean KS standard and the most widely used for domestic logistics. T12 (1200×1000mm) is ISO-compatible and works well for loading export containers. EUR (1200×800mm) is the European standard pallet.

How many boxes fit on a standard pallet?

It depends on the box dimensions and the pallet size. Enter the box dimensions and stack height in this calculator, and it will automatically compute the number of boxes per layer and the number of stacked layers.

What is the recommended pallet stacking height?

General cargo is typically stacked to 1.4–1.6 m, or below 1.2 m when greater stability is required. For container loading, a 40HC allows up to about 2.4 m, but cargo stability should always be reviewed first.

What is pallet overhang?

Overhang is when boxes extend past the edge of the pallet. Overhang of 5 cm or more increases the risk of damage during storage and transport, so we recommend a box layout that is smaller than or equal to the pallet.

What loading algorithm does this calculator use?

It rotates the box in both the lengthwise and widthwise directions and automatically selects the orientation that fits more boxes per layer. It assumes every box is stacked in a grid in the same orientation; real-world transport may apply additional patterns such as interlocking.

Pallet Sizes Commonly Used in Korea

The most common pallet in domestic logistics is the T11 (1100×1100mm), the Korean KS standard, optimized for domestic truck and warehouse infrastructure. The T12 (1200×1000mm) is ISO-compatible and offers better space efficiency when loading 20ft·40ft containers, so it is frequently chosen for exports. The EUR (1200×800mm) is the standard for shipments to Europe.

Pallet Loading Guide

1. Improve loading efficiency by rotating boxes

Try the box in both the lengthwise and widthwise directions and choose the one that fits more boxes per layer. This calculator automatically compares both orientations and shows the optimal layout.

2. Watch out for overhang

When boxes extend 5 cm or more past the edge of the pallet, the risk of corner damage during storage and transport increases. Where possible, adjust the box layout so it stays within the pallet.

3. Prioritize stability for stack height

General cargo is typically 1.4–1.6 m. For heavy cargo or cargo prone to shifting, lower it to 1.2 m or less. For container loading, a 40HC allows up to about 2.4 m.

4. Interlocking pattern

Rotating the box orientation 90° on each layer greatly improves stacking stability (a brick-laying pattern). The number of boxes per layer stays the same, but it reduces collapse during transport.

Frequently Asked Questions

Should I choose a T11 or a T12 pallet?

If the main purpose is domestic transport and warehouse storage, the T11 (1100×1100, KS standard) is the safest choice. If you plan to load export containers, the T12 (1200×1000) fits a 40ft container more efficiently (one container holds 20 T12 pallets versus 10 T11 pallets).

What is the recommended stacking height on a pallet?

General cargo is typically 1.4–1.6 m; cargo requiring greater stability should be below 1.2 m. For container loading, a 20ft·40ft DC allows about 2.2 m and a 40HC about 2.4 m, but shifting during transport and cargo stability should be reviewed together.

What happens if the box is larger than the pallet?

If one side of the box exceeds the pallet dimensions, stable loading is difficult. This calculator automatically tries both rotation orientations, but if it fits in neither, it displays a warning. Consider a larger pallet (T12) or splitting the box.

How is total CBM calculated after pallet loading?

Total CBM = volume of one box (m³) × boxes per layer × number of layers. This calculator takes box dimensions (cm) and automatically converts to meters to compute the result. 1 CBM = 1 m³ = length (m) × width (m) × height (m).

Will actual transport differ from the calculator's values?

This calculator gives theoretical values based on same-orientation, grid loading. In practice, interlocking patterns, cushioning, and weight distribution may reduce the boxes per layer, or the stack height may be lowered for stability. An accurate quote is determined after consulting on the cargo's characteristics.

* 1 CBM = 1 m³ = length (m) × width (m) × height (m). Boxes per layer is the optimal value after comparing the box in both rotation orientations, and number of layers = floor(stack height ÷ box height). Actual transport may vary with interlocking, cushioning, and weight distribution.
