How many 40ft containers fit on a cargo ship?
Just like a shipping container, cargo ships also come in different models and sizes. Each of them exists because of different cargo types, port limitations, trade routes, efficiency, and costs.
Cargo ships are used to carry standardized shipping containers, most common in global trade. They are measured in TEU (Twenty-foot Equivalent Units).

What is a TEU in Container Shipping?
A TEU is a Twenty-foot Equivalent Unit. It is the international standard unit of measurement for container transportation capacity.
Containers come in a variety of sizes. TEUs are used to standardize the capacity of all container types. 1 TEU represents a standard 20’ (6.1 m) container.
2 TEUs represent a standard 40’ (12.2 m) container, as a 40’ container is twice as long as a 20-foot container.
TEUs are an important indicator used by shipping companies, port authorities, and freight forwarders worldwide to measure capacity, cargo throughput, and logistics scale.
Types of Container Ship Available in the World
To better understand how capacity directly correlates with ship size, the table below will explain you how many 40ft containers fit on a cargo ship.
Table Comparison of Container Ship Capacity
| Ship Type | TEU Capacity | 40ft Container Capacity |
|---|---|---|
| Feeder | 1,000 | 500 |
| Feedermax | 1,000-2,000 | 500-1,000 |
| Post-Panamax | 3,000-5,000 | 1,500-2,500 |
| New Panamax | 10,000-14,000 | 5,000-7,000 |
| Ultra Large Container Vessel | 24,0000 | 12,000 |
This comparison clearly demonstrates how container ship size determines the number of containers a ship can carry, with ultra-large container ships setting the maximum benchmark.
Feeder
A container feeder ship is a small to medium-sized, designed to transport containers between smaller regional ports and larger hub ports, where containers are transferred to or from larger ocean-going vessels (like ULCVs).
It is called a feeding ship as it supports large shipping lines by “feeding” containers in and out of hub ports.
Feeder ships are a crucial part of the hub-and-spoke system in global maritime logistics. Its capacity is <1,000 TEU, with a beam that is narrower than large vessels; it fits small ports.
This ship is flexible and versatile as it can navigate narrower waterways and smaller ports (e.g., rivers, estuaries).
Feedermax
The Feedermax container ship has the largest capacity within the feeder segment, with a capacity of 1,000-2,000 TEU.
It plays a crucial role in regional and short-sea container transport, especially in connecting smaller ports to major transshipment hubs.
This type reduces congestion at major ports by spreading container handling regionally, while it can still enter smaller ports with draft and berth restrictions, unlike large vessels.
Feedermax is large enough to achieve economies of scale compared to smaller feeders. Used heavily in intra-Asia, intra-Europe, West Africa, and Caribbean routes.
Post-Panamax
The post-panamax ship is built to fit the original Panama Canal locks. Designed to carry larger volumes of containers on global shipping routes, the ship can accommodate 3,000-5,000 TEU.
These ships are part of the evolution toward larger, more efficient container vessels driven by trade growth and the need for economies of scale.
The original Panama Canal locks limited ship dimensions to length 294 m, beam 32.3 m, and draft 12.04 m.
Post-Panamax ships exceed these dimensions, particularly in beam, and therefore couldn’t transit the canal until it was expanded in 2016.
These ships paved the way for even bigger vessels like New Panamax and ULCVs, following canal and port infrastructure upgrades.
New Panamax
The new Panamax ship fits the new Panama Canal locks (after 2016), revolutionized global shipping by unlocking a faster route between Asia and the U.S. East Coast via the Panama Canal.
This expansion allowed for much larger ships than the original canal locks could accommodate.
The ship can contain 10,000 – 14,000 TEU and has an efficient hull and engine optimized for fuel consumption at high loads. It can also carry 7-9 containers high above deck.
However, this ship can only go to deepwater ports with Post-Panamax cranes can handle them. Fully loaded transit depends on water levels in Gatun Lake.
Ultra Large Container Vessel (ULCV)
The ULCV ship is used on major intercontinental routes (e.g., Asia-Europe). It is the largest class of container ship in the world, designed to carry more than 14,000 TEUs, with some exceeding 24,000 TEUs.
Modern ULCVs are designed with optimized hull forms and slow-steaming engines to reduce fuel consumption and emissions. However, ULCVs can only call at mega-ports with:
- Deepwater berths (≥17 meters)
- High-capacity gantry cranes (24-row outreach)
- Large storage yards and high throughput
The ship requires tug assistance for port navigation. It is also slower than smaller ships due to size and energy efficiency strategies (slow steaming).
Turning Used Containers Into Workshops and Shipping Container Garages
Why Can Larger Ships Carry More Containers?
Larger ships are able to carry more shipping containers because:
- A wider beam allows for more rows of containers.
- A stronger hull structure to support higher stacked containers.
- A better stability system for heavy container loads.
- Optimized deck layouts and storage spaces.
However, increasing ship size also increases reliance on major container ports and specialized infrastructure.
