Choosing between a 20ft and 40ft shipping container is one of the first — and most important — decisions you’ll make when buying or renting a container. Pick the wrong size and you’re either paying for space you don’t need or cramming your belongings into something too small.
In this guide, we’ll break down the key differences between 20ft and 40ft shipping containers: dimensions, cost, weight capacity, best use cases, and delivery considerations — so you can make the right call with confidence.
Dimensions: How Much Space Do You Actually Get?
20ft Shipping Container Dimensions
| Measurement | Exterior | Interior |
|---|---|---|
| Length | 20′ (6.1m) | 19’3″ (5.9m) |
| Width | 8′ (2.4m) | 7’8″ (2.4m) |
| Height | 8’6″ (2.6m) | 7’9″ (2.4m) |
| Volume | — | ~1,169 cu ft (33 CBM) |
40ft Shipping Container Dimensions
| Measurement | Exterior | Interior |
|---|---|---|
| Length | 40′ (12.2m) | 39’5″ (12.0m) |
| Width | 8′ (2.4m) | 7’8″ (2.4m) |
| Height | 8’6″ (2.6m) | 7’9″ (2.4m) |
| Volume | — | ~2,390 cu ft (67 CBM) |
The width and height are identical — the only difference is length. A 40ft container gives you roughly twice the floor space of a 20ft, making it ideal when you need to store large equipment, vehicles, or high-volume inventory.
Cost: compare delivered quotes for your ZIP
Container condition, size, availability and delivery access affect the quote. Ask for the same condition and delivery address when comparing a 20ft with a 40ft. A lower container-only price does not necessarily mean a lower delivered cost.

Weight Capacity: Which Can Hold More?
| 20ft Container | 40ft Container | |
|---|---|---|
| Tare Weight (empty) | ~4,900 lbs (2,200 kg) | ~8,800 lbs (4,000 kg) |
| Max Payload | ~47,900 lbs (21,700 kg) | ~59,000 lbs (26,760 kg) |
| Max Gross Weight | ~52,900 lbs (24,000 kg) | ~67,200 lbs (30,480 kg) |
Best Use Cases: When to Choose Each Size
When a 20ft Container Makes Sense
A 20ft container is the most popular choice for good reason — it’s versatile, maneuverable, and fits in tighter spaces.
- Residential storage: Moving, downsizing, or seasonal storage on a residential property
- Small business storage: Storing tools, supplies, or inventory for small operations
- Pop-up shops and offices: Compact enough to place in parking lots or urban lots
- Tight delivery locations: Narrow driveways, limited access sites, or smaller properties
- Container homes and studios: A popular base for a compact home office, art studio, or guest room
When a 40ft Container Makes Sense
A 40ft container is the go-to for anyone who needs serious space.
- Commercial storage: Warehousing inventory, equipment, or seasonal stock
- Construction sites: Storing tools, materials, and machinery on large job sites
- Container restaurants and retail: More interior space for build-outs
- Vehicle storage: Fits most cars, ATVs, motorcycles, and small boats
- Multi-room container homes: Enough space to create a full living layout
Delivery and Site Requirements
A 20ft container has a shorter footprint, but that alone does not confirm truck access. Both sizes need a review of the entrance, turns, ground, overhead obstacles and working space for the selected unloading method.
Before choosing, use our container delivery site worksheet and photo checklist. Record your measurements and intended door direction, then ask the team to confirm the delivery plan. Do not use container length as the required truck clearance.
Choose a size in three steps
- List what you will store, including item dimensions and the space needed to reach it.
- Compare that layout with the usable interior and door opening of the specific container offered.
- Have the delivery route and placement area reviewed before booking.

Frequently Asked Questions
Is a 40ft container exactly twice the size of a 20ft?
Almost — but not quite. A 40ft container has approximately 2x the floor space and volume of a 20ft. The width and height are identical; only the length doubles.
Which is cheaper to buy — a 20ft or 40ft?
Compare current delivered quotes for the same condition and ZIP code. The best choice depends on the storage space you need, availability and the delivery plan.
Which size is better for a container home?
A 20ft works well for a studio or home office. For a full living space with bedroom, bathroom, and kitchen, a 40ft — or combination of containers — is the better choice.
Do you offer both sizes for rent in Los Angeles?
Yes. Shipping Container Depot offers both 20ft and 40ft containers for sale and for rent throughout California. Contact us for current availability and pricing.
The Bottom Line
If you’re storing household goods, running a small business, or building a compact space — a 20ft container hits the sweet spot of size, price, and ease of delivery.
