6 Standard Containers at a Glance – and When Each Is Appropriate

Logistics professionals, freight forwarders and exporters face the question every day: which container type fits the cargo? This article presents the six most common standard containers, shows typical use cases (e.g. refrigerated goods, furniture, machines) and explains how you can make economical decisions with systematic transport planning.

The Six Standard Containers (Internal Dimensions & Volume)

| Container type | Internal dimensions (H×L×W) | Volume | Typical use | |---|---:|---:|---| | 45ft Standard | 2.34 × 13.55 × 2.36 m | 74.63 m³ | Large volume for lightweight goods | | 45ft High Cube | 2.34 × 13.55 × 2.655 m | 84.16 m³ | Extra height for bulky or tall goods | | 40ft Standard | 2.35 × 12.03 × 2.39 m | 67.69 m³ | All-rounder for many types of goods | | 40ft High Cube | 2.35 × 12.03 × 2.655 m | 76.36 m³ | More space for tall loads | | 20ft Standard | 2.35 × 5.90 × 2.39 m | 33.17 m³ | Small shipments, heavy goods (payload) | | 20ft High Cube | 2.35 × 5.90 × 2.655 m | 37.38 m³ | More height for low-volume, tall goods |

Note: The figures are internal dimensions; usable capacity can be reduced by packaging, cargo distribution and weight restrictions.

When Each Container Type Is Economically Sensible

• 20ft Standard / High Cube: Economical for smaller shipments or heavy goods where allowable payload is more important than volume. Often chosen for industrial machines, heavy parts and compact deliveries.
• 40ft Standard: The universally applicable container for many exports. Good for palletized goods, general cargo and mixed loads. Often the best compromise between volume and handling costs.
• 40ft High Cube: When goods are higher than usual (e.g. racking systems, light tall goods) or better space utilization without stacking is desired.
• 45ft Standard / 45ft High Cube: Useful for large volumes where unit weights are low (e.g. plastic parts, light packaging). The High Cube offers additional height advantage.

Economic factors: price per m³, handling fees and weight limits. For very dense goods (high weight / low volume) a 20ft can be cheaper; for light, bulky goods a 40ft or 45ft often pays off.

Industry Comparisons: Refrigerated Goods, Furniture, Machines

• Refrigerated goods (Reefer containers): Perishable goods require reefer containers for temperature control. For reefers, besides volume, maximum payload and power supply are important. For deep-frozen products or temperature-sensitive foods, specific reefer capacities and temperature zones must be considered.

• Furniture: Furniture and furnishings often benefit from High Cube variants (40ft HC or 45ft HC). The extra height reduces empty space and avoids cumbersome stacking. For partial loads, 20ft containers or combining several 20ft containers can be economical.

• Machines: Machines are often heavy and bulky. Payload capacity and loading options (lashing points, door width) count here. Heavier machines often fit better into 20ft containers if the length is sufficient; for longer installations consider 40ft or specialized flat-rack containers.

Practical figures: A 20ft container typically holds around 10 Euro pallets (120×80 cm), a 40ft about 20 pallets. These values can vary depending on pallet size and loading method.

How CoLoCa Delivers Your Container Recommendation Automatically

CoLoCa is a container loading calculator that simplifies transport planning and container recommendation. Users enter dimensions or volume of their items (also in different units) and immediately receive:

• Volume calculation in m³ and ft³
• Automatic utilization calculation for six standard container types
• Remaining volume and percentage utilization
• Color-coded indicators (Green = underutilized, Yellow = optimal, Red = critical, Black = overloaded)

The tool is specifically tailored to users in forwarding, export and logistics: for quick quotes, a basis for decisions and to avoid over- or underloading. Thanks to an easy-to-understand presentation, container recommendations can be integrated directly into transport planning.

Combining Multiple Containers and Overall Calculation

Often the best solution is not a single container but a combination. Examples:

• Consolidation: Three partial loads of 12 m³ each together make 36 m³. That can fit into a 40ft Standard (67.69 m³) or be economically distributed into two 20ft containers — depending on cost per container and handling.
• Splitting: 100 m³ total volume → 1×45ft HC (84.16 m³) + 1×20ft Standard (33.17 m³) provides enough space and reduces empty space in the 45ft.

Tip: Compare percentage utilization and remaining m³ for each combination. Utilization between 70–90% is often economically optimal (yellow), as it leaves buffer capacity without causing excessive container costs.

Practical Tips for Transport Planning

• Check weight vs. volume: For high density, weight counts; for light goods, volume matters.
• Use High Cube when the height of the goods makes a difference — this often saves another pallet or a second container.
• For refrigerated goods, reserve reefer space early and document temperature profiles.
• Record packing lists and pallet dimensions precisely — small changes strongly affect utilization.
• Use tools for quick container recommendation to compare different scenarios (e.g. combinations, pallet configurations).

Conclusion

The right container choice depends on volume, weight, type of goods and cost structure. 20ft containers are ideal for heavy, compact loads; 40ft containers are the all-rounder; 45ft variants are suitable for large volumes. For temperature-sensitive goods, the reefer container is mandatory. With structured transport planning and a volume calculator like CoLoCa you get fast, reliable container recommendations and avoid wrong decisions.

Try different scenarios: Small adjustments in pallet distribution or choosing a High Cube can reduce costs and make logistics more efficient.
