How Many Pallets Fit in a 20ft Container? A Comprehensive Guide
If you’re shipping goods, a key question often arises: just how many pallets can you fit in a 20ft container? The answer is essential for planning shipments, optimizing costs, and ensuring goods arrive safely and efficiently. Let’s break down everything you need to know, from pallet types to practical tips for maximizing container space.
The Short Answer: Pallet Capacity in 20ft Containers
A standard 20ft shipping container can typically accommodate:
- 10 to 11 standard (Euro) pallets (1200mm x 800mm)
- 8 to 10 standard (ISO/North American) pallets (1200mm x 1000mm)
These numbers assume a single layer of pallets placed on the container floor. The exact count can vary depending on pallet type, how tightly pallets are packed, and the size or shape of the goods loaded.
Understanding Container and Pallet Sizes
Before diving into calculations, it’s important to understand the standard sizes involved:
Standard 20ft Container Internal Dimensions
- Length: 5.9 meters (19 feet, 4 inches)
- Width: 2.35 meters (7 feet, 8 inches)
- Height: 2.39 meters (7 feet, 10 inches)
- Usable Floor Space: Approximately 13.5 square meters (146 square feet)
Common Pallet Types
- Euro Pallet
- Size: 1200mm x 800mm (47.2 in x 31.5 in)
-
Widely used in Europe and increasingly worldwide
-
Standard (ISO or North American) Pallet
- Size: 1200mm x 1000mm (48 in x 40 in)
-
Common in the United States, Canada, and parts of Asia
-
Other Pallet Variations
- Some regions use different sizes, but Euro and standard are most common for international shipping.
How Pallets Are Arranged in a 20ft Container
The way you load pallets affects how many can fit. There are two common arrangements:
- Straight (Block) Stacking: Pallets are placed parallel to the container walls.
- Turned (Pinwheel) Stacking: Pallets are alternately turned 90 degrees. This sometimes helps fit an extra pallet but can increase handling difficulty.
Typical Configurations
- Euro Pallets: 5 along the length, 2 across the width = 10 pallets per layer
- Standard Pallets: 4 along the length, 2 across the width = 8 pallets per layer
Occasionally, with tight packing and minimal loading gaps, shippers may fit one extra pallet, resulting in 11 (Euro) or 9-10 (standard) per layer. However, you should not count on this for all shipments.
Detailed Steps to Calculate How Many Pallets Fit
- Measure Usable Space
- Factor in the container’s internal length and width.
-
Consider the door frame, wall protrusions, and pallet overhang.
-
Select Pallet Type and Orientation
- Use the pallet size that best matches your cargo.
- Try different orientation methods if your cargo allows.
- Consider Pallet Load Height
- For double stacking or taller cargo, check container height clearance.
-
Standard container height is ~2.39 m, but high-cube containers add another ~0.30 m (1 ft).
-
Leave Space for Airflow and Handling
- Don’t pack containers so tightly that forklifts or workers cannot safely load and unload pallets.
Benefits of Using Pallets in Shipping Containers
- Efficient Loading & Unloading: Pallets speed up handling, reducing labor costs and turnaround time.
- Cargo Protection: Keeping goods off the floor minimizes moisture and physical damage.
- Optimized Space Usage: Pallets help you neatly organize your load, making the best use of available space.
- Easier Inventory Control: Pallets keep shipments organized and easy to count.
Challenges When Packing Pallets in a 20ft Container
While using pallets is efficient, there are some challenges to be aware of:
- Not All Goods Stack Evenly: Irregularly shaped or fragile items might result in unused space.
- Maximum Weight Limit: A 20ft container can typically handle up to around 28,000 kg (61,700 lbs) gross weight (container plus cargo). Overloading is unsafe and can result in fines.
- Pallet Condition: Poor-quality or damaged pallets could break, risking damage to your goods.
- Customs or Biosecurity Regulations: Some countries require fumigation or treatment of wooden pallets; always check requirements.
Practical Tips for Maximizing Space in a 20ft Container
Want to make the most out of your shipping container? Here are some proven strategies:
1. Choose the Right Pallet Size
- If possible, use Euro pallets for a tighter fit in 20ft containers, since their narrower width fits two abreast side by side.
2. Use Quality Pallets
- Good condition ensures stability, protects your goods, and makes stacking safer.
3. Optimize Palletizing Patterns
- Stack boxes to the edge of the pallet—minimize overhang or empty corners.
- Consider shrink wrapping or strapping for pallet stability.
4. Don’t Overload!
- Respect container and pallet weight limits for safety and legal compliance.
- Double-check individual pallet weights, as well as combined load.
5. Secure Your Load
- Use load bars, straps, or airbags to prevent shift during transit.
6. Plan Ahead
- Measure the height, width, and length of your cargo (on the pallet) to check stacking feasibility.
- Create a loading diagram for your team to follow.
7. Consider Container Height (Standard vs. High Cube)
- For taller loads, request a “high cube” container (roughly 30 cm taller inside).
- This can allow for double-stacking lower-height pallets, increasing total volume moved per container.
Cost Tips: Reducing Shipping Expenses
Smart palletization leads directly to shipping savings:
- Maximize Every Inch: The closer you get to the max pallet count per container, the lower your cost per pallet.
- Consolidate Shipments: Combine loads where possible to avoid shipping partially empty containers.
- Select Pallet Appropriate for Your Cargo and Destination: Avoid repacking or fines due to incorrect pallet type or untreated wood.
- Work with Experienced Freight Forwarders: They can advise on packing layouts and help avoid costly mishaps.
- Balance Load and Weight: Overweight containers can incur fines or be rejected at ports, causing expensive delays.
Going Beyond: When a 20ft Container Isn’t Enough
If your cargo exceeds the pallet capacity of a 20ft container, you may consider:
- Using a 40ft Container: Offers roughly double the space, with similar per-pallet transport costs.
- Shipping in Bulk: For loose or oddly shaped goods, alternative loading methods (loose-loaded, floor-loaded) may be more appropriate.
- Consulting Logistics Experts: A professional forwarder can help with cargo consolidation and container selection.
Summary
A standard 20ft shipping container will generally hold 10-11 Euro pallets or 8-10 standard (North American) pallets. The exact number depends on pallet type, orientation, and the cargo itself. Optimization means more than simply squeezing in every possible pallet; it also involves safe loading, regulatory compliance, and ensuring your goods arrive efficiently and intact. Careful planning and following best practices will help you maximize space and keep shipping costs under control.
Frequently Asked Questions (FAQs)
How many Euro pallets fit in a 20ft container?
A standard 20ft container holds up to 11 Euro pallets (1200mm x 800mm), but the most common fit is 10 pallets in a single layer, placed two across and five down the container length.
How many standard (ISO/North American) pallets fit in a 20ft container?
Generally, you can fit 8–10 standard pallets (1200mm x 1000mm) in a 20ft container. The more common and comfortable fit is 8, depending on the load configuration and exact pallet construction.
Can I double stack pallets in a 20ft container?
Double stacking is possible if your cargo is not fragile and the combined height does not exceed the container ceiling. Use strong pallets and ensure the total weight and balance are safe for transit.
What is the maximum weight for a 20ft container?
The maximum gross weight (container plus cargo) for a 20ft container is generally about 28,000 kg (61,700 lbs). Always check with your shipping provider and local regulations, as max weight can vary depending on route and mode of transit.
Do pallet materials or treatments affect international shipments?
Yes. Many countries require wooden pallets to be heat treated or fumigated to prevent the spread of pests. Always ensure your pallets meet the International Standards for Phytosanitary Measures (ISPM-15) for export shipments.
With these tips and insights, you can confidently plan your 20ft container shipping, maximizing efficiency, safety, and value for your business.
