**40 guides**, **7 sizes**, **10 container types** and **9 free tools** answer 455 questions about shipping containers, and each page opens with its answer and the figure before any explanation. Search them below, or start from the errand you came with.

## The eight questions most readers arrive with

Each answer is the opening sentence of the guide it comes from, so it carries the figure you need. The guide behind it has the table, the drawing and the exceptions.

- **Is there one chart with every container size?**: ISO 668 makes a container 8 ft (2.438 m) wide, 8′6″ or 9′6″ (2.591 / 2.896 m) high and 10, 20, 40 or 45 ft (2.991 / 6.058 / 12.192 / 13.716 m) long; this chart gives all 17 containers: outside, inside, door, weights and pallets, in metres and feet.[Full guide: Container size chart (all 17)](https://contsize.com/shipping-container-dimensions-chart/)
- **Should I book a 20 ft or a 40 ft?**: A 20 ft container is 6.058 m (19′10½″) long and a 40 ft 12.192 m (40′), on the same 2.438 × 2.591 m (8′ × 8′6″) cross-section.[Full guide: 20 ft vs 40 ft container](https://contsize.com/20-ft-vs-40-ft-container/)
- **How many pallets fit in a 40 ft?**: A 40 ft container takes 25 Euro pallets (EUR, 1200 × 800 mm, 47.2 × 31.5 in) or 21 US GMA pallets (48 × 40 in, 1219 × 1016 mm) floor-loaded in one tier with every pallet tight, as our pallet calculator lays them: the EUR pallets in two bands, one lengthwise…[Full guide: Pallets in a 40 ft container](https://contsize.com/pallets-in-40-ft-container/)
- **How much does a container weigh?**: An empty 20 ft container weighs about 2,230 kg (4,916 lb), within 2 % of what 8 of 18 published sheets print (they range 2,080–2,570 kg), a 40 ft about 3,700 kg (8,157 lb) and a 40 ft high cube about 3,830 kg (8,444 lb), within 2 % of what 9 of 16 and 10 of…[Full guide: Shipping container weight](https://contsize.com/shipping-container-weight/)
- **How do I work out my cargo volume?**: A 20 ft container holds 33.2 m³ (1,172 ft³) inside, a 40 ft 67.7 m³ (2,391 ft³) and a 40 ft high cube 76.4 m³ (2,698 ft³) — as 18 of 18, 15 of 16 and 19 of 19 published line and maker sheets print them; a 45 ft holds about 86.0 m³.[Full guide: Container CBM guide](https://contsize.com/container-cbm/)
- **What does a container cost to buy?**: A used [cargo-worthy](https://contsize.com/glossary/cargo-worthy/) 20 ft container costs $1,700–2,800 in the US in October 2026 and a used 40 ft high cube $2,100–3,500; new ([one-trip](https://contsize.com/glossary/one-trip/)) they run $2,800–4,400 and $4,000–5,600.[Full guide: Shipping container prices](https://contsize.com/shipping-container-prices/)
- **Which condition grade should I buy?**: Container grades from best to worst: one-trip (single loaded voyage, effectively new), IICL (passes the strictest leasing-industry inspection), cargo-worthy (CW — certified for ocean shipping, valid CSC), wind & water tight ([WWT](https://contsize.com/glossary/wwt/) — weatherproof but not…[Full guide: Container grades & condition](https://contsize.com/container-grades/)
- **Can I build a home from containers?**: A shipping container home is built from 20 ft boxes (13.9 m² / 149 ft² of inside floor each) or, far more often, 40 ft high cubes (28.3 m² / 305 ft² each, 2.698 m / 8′10″ inside height — about 2.5 m after 200 mm of floor build-up and ceiling insulation), the…[Full guide: Container home dimensions](https://contsize.com/container-home-dimensions/)

### One question, one page

Seven questions answered in a page each: the figure first, in both unit systems, then one table and where the figure comes from.

## Three reading paths

Most people come with an errand, not a topic. These are the guides for the three commonest ones, in the order the decisions actually come up.

### Shipping cargo for the first time

You have goods and need to know which container to book and how to fill it.

1. [Container size chart (all 17)](https://contsize.com/shipping-container-dimensions-chart/)Know the inside of each box before anything else: internal size, door opening, volume.
2. [20 ft vs 40 ft container](https://contsize.com/20-ft-vs-40-ft-container/)Choose the size. It is decided by cargo density, not by how much you have.
3. [Container CBM guide](https://contsize.com/container-cbm/)Turn your cartons into cubic metres, the unit every quote is written in.
4. [Shipping container weight](https://contsize.com/shipping-container-weight/)Check weight. Payload, the road limit and the VGM rule can each stop a full box.
5. [Pallets in a 40 ft container](https://contsize.com/pallets-in-40-ft-container/)Lay out the floor: how many pallets, and in which pattern.

[Then put your own numbers into the calculators.](https://contsize.com/container-calculators/)

### Buying a container

You want a box of your own for storage, a workshop or a project.

1. [Shipping container prices](https://contsize.com/shipping-container-prices/)Start with what the market charges, by size and condition.
2. [Container grades & condition](https://contsize.com/container-grades/)Learn the grades, because "cargo-worthy" and "wind and watertight" are not the same promise.
3. [Buying a container: checklist](https://contsize.com/buying-a-shipping-container/)Inspect before paying: a checklist of what fails and where to look.
4. [Moving a shipping container](https://contsize.com/moving-a-shipping-container/)Plan delivery. The truck and the access often cost more thought than the box.
5. [Container foundations](https://contsize.com/container-foundation/)Prepare the ground it will stand on.

[Then compare the sizes side by side.](https://contsize.com/container-comparison/)

### Building with a container

You are turning a box into a room: a home, an office, a cabin.

1. [Container home dimensions](https://contsize.com/container-home-dimensions/)See what the dimensions allow and what they do not, starting with the 2.35 m internal width.
2. [Container foundations](https://contsize.com/container-foundation/)Get the foundation right; everything else sits on the four corner castings.
3. [Container insulation](https://contsize.com/shipping-container-insulation/)Insulate. A steel box is the hardest envelope there is to keep dry and warm.
4. [Ventilation & condensation](https://contsize.com/container-ventilation-condensation/)Ventilate, or condensation undoes the insulation.
5. [Container flooring](https://contsize.com/container-flooring/)Deal with the floor, which was treated for cargo, not for living on.

[Then read the page for the size you plan to use.](https://contsize.com/40-ft-high-cube-container/)

## Every guide, by what you are trying to do

Reading time is counted from the text; the date is when the guide last changed in substance.

### Dimensions and units

What size a container is, in which unit, and how to read the codes painted on it.

## How these guides are made

- Every figure comes from one dataset, the same one behind the specification tables, so a guide and a table cannot disagree.
- Each of the 191 container figures carries its status and the documents behind it: 44 set by ISO 668 and ISO 1496-1 (read in IS 6566:2001, ГОСТ Р 51876-2008 and ГОСТ Р 53350-2009), 114 printed alike by most of the published sheets, 21 where the sheets spread and 12 from a single sheet. The data sources page gives them figure by figure; the citations page lists all 308 documents read.
- Where the sheets differ, a page gives the most common figure and the span the sheets print, never one number as if it were the only one.
- A guide opens with its answer. If the first sentence does not carry the verdict and the figure, we treat that as a defect.
