Container Load Calculator

What is a container load calculator?

A container load calculator helps you determine how your cargo fits inside shipping containers. It calculates volume utilization, weight distribution, and recommends optimal container sizes (20ft, 40ft, or 40ft High Cube) based on your cargo dimensions and weight.

What are the standard shipping container sizes?

The three most common container sizes are:

• 20ft Standard: 5.9m x 2.35m x 2.39m internal, 33.2 CBM capacity, 28,200 kg max payload
• 40ft Standard: 12.03m x 2.35m x 2.39m internal, 67.7 CBM capacity, 26,680 kg max payload
• 40ft High Cube: 12.03m x 2.35m x 2.69m internal, 76.3 CBM capacity, 26,460 kg max payload

When should I use LCL vs FCL shipping?

LCL (Less than Container Load) is best when your cargo fills less than 30% of a container - you share space with other shippers and pay per CBM. FCL (Full Container Load) typically becomes more economical when your cargo exceeds 50% utilization, offering faster transit times, reduced handling, and better security.

How do I calculate CBM for my cargo?

CBM (Cubic Meter) is calculated by multiplying Length x Width x Height in meters. For example, a box measuring 100cm x 80cm x 60cm equals 1m x 0.8m x 0.6m = 0.48 CBM. Multiply by quantity for total volume. Our calculator handles this automatically - just enter dimensions in cm or inches.

Why is weight distribution important in container loading?

Proper weight distribution prevents container tipping during transport, ensures safe handling by cranes and trucks, and complies with international shipping regulations. Weight should be evenly distributed front-to-back and side-to-side, with heavier items placed at the bottom. Our calculator analyzes weight distribution and warns you of imbalances.

What is container utilization and why does it matter?

Container utilization is the percentage of available space used by your cargo. Higher utilization (80%+) means better cost efficiency - you're paying for space, so using more of it reduces your per-unit shipping cost. Our calculator optimizes item placement to maximize utilization while respecting weight limits and stacking constraints.

Can I ship items that don't fit in a single container?

Yes! Our calculator automatically detects when cargo exceeds a single container's capacity and splits it across multiple containers. It optimizes the container mix - for example, using one 40ft High Cube and one 20ft Standard - to minimize costs while fitting all your cargo.
