Is a 20ft right — or are you about to overpay for space you can't use?

The 20ft is the most-bought container in the country, but it isn't automatically the right answer. Three quick checks before you spend a dollar.

Choose 20ft when…

You need secure storage for a 1–2 car garage's worth of gear, a jobsite lockup, a small workshop, or a heavy/dense load. It drops in one piece on most driveways and farm lots.

Size up to 40ft when…

You're storing long items (lumber, kayaks, vehicles) or want roughly double the floor for only ~25–30% more — but only if your lot can take a 60ft+ truck and a longer pad.

Size down to 10ft when…

You have a tight side-yard or alley, only need a shed-sized lockup, and want the easiest possible placement. You'll pay more per cubic foot, though.

The detail most buyers miss:

A 20ft and a 40ft share the same 30,480 kg (67,200 lb) maximum gross weight. With dense cargo — machinery, tools, tile, aggregate — you'll hit the weight ceiling long before you fill a 40ft. For heavy loads, a 20ft is often the smarter buy, not just the cheaper one. Compare 10ft vs 20ft vs 40ft →

To scale

What a 20ft actually holds

Exterior, interior and the all-important door opening. The door gap — not the box — is what decides whether your widest item fits.

Standard vs. 20ft High Cube — one foot that's worth paying for (sometimes)

A high cube is exactly the same footprint but a foot taller (9'6" vs 8'6"). On a 20ft that extra foot is rarer and costs a little more — worth it only if you need the vertical room.

The decision that sets your price

Grade decoder: what you're really buying at each price

"New" and "used" barely describe it. These four grades are the language every supplier uses — and the single biggest lever on what you pay. Prices are typical U.S. container ranges for 2026, before delivery.

One-Trip / "New" Near-factory condition, one ocean voyage ~$2,800–$5,000before delivery

What it is

Built overseas, loaded once for the trip to the U.S., then sold. Clean paint, intact marine-ply floor, square doors, little to no rust — effectively new.

Best for · watch-outs

Best for: backyard offices, retail/pop-up builds, anything you'll modify, cut or want to look sharp.

Premium grade — often only ~$1,000–$1,500 more than a used box. Confirm it's truly one-trip, not "refurbished."

Cargo-Worthy (CW) Certified seaworthy — the balanced choice ~$1,400–$3,000before delivery

What it is

Inspected and certified structurally sound enough to be stacked and shipped internationally. Expect dings, surface rust and honest wear, but guaranteed wind- and watertight.

Best for · watch-outs

Best for: long-term storage, export, conversions on a budget, anywhere structure matters more than looks.

For export you'll need a current CSC plate / survey — confirm the certification date before buying.

Wind & Water Tight (WWT) The budget storage workhorse ~$1,225–$2,500before delivery

What it is

Guaranteed to keep wind and water out, but not certified for ocean cargo. Same steel, more character. The most popular grade for people who just need dry, secure space.

Best for · watch-outs

Best for: on-site storage you'll never ship overseas — tools, equipment, inventory, seasonal gear.

Floors can have soft spots from delamination. If you'll drive a forklift inside, step up to CW for a solid floor.

As-Is Cheapest — and the most "buyer beware" ~$500–$1,500before delivery

What it is

Sold with no condition guarantee. May have dents, heavy rust, even holes or a damaged door. Often a unit that wasn't economical to repair or couldn't be inspected.

Best for · watch-outs

Best for: covered/dry storage of items that don't mind a leak, or a cheap base for a heavy rebuild.

Never buy As-Is sight-unseen. If a "WWT-priced" box is being sold As-Is, that's a red flag — see below.

Rule of thumb:

If you'll never put the box on a ship, WWT gives you the same weatherproofing as CW for less. Pay the CW premium only when you need a certified, solid-floor unit or plan to export. Get a delivered price for your ZIP and grade →

2026 numbers

What it really costs — container, delivery, and the line items people forget

Most sellers quote the box and add delivery separately, sometimes at the very end. Here's the whole picture so nothing surprises you at checkout.

Grade (20ft standard)Typical container price*Best fit
One-Trip / "new"~$2,800–$5,000Offices, retail, conversions, clean look
Cargo-Worthy (CW)~$1,400–$3,000Export, long-term storage, solid floor
Wind & Water Tight~$1,225–$2,500Everyday secure, dry storage
As-Is~$500–$1,500Rough storage or a rebuild base
20ft High CubeAdd ~$150–$400 over standardVertical clearance, racking

*U.S. container price ranges before delivery, 2026 market. Used 20ft units commonly run about $1,225–$3,000 and one-trip units start near $2,800; delivered totals for used boxes often land around $2,500–$3,500. Your price moves with depot proximity and steel prices. (Sources: Container Sales Group, ShipMate+, Pelican Containers, Container One — 2026.)

Delivery: the second invoice

Plan for roughly $150–$1,550 depending on distance. Many yards charge a base fee plus mileage (e.g. ~$250 + ~$5/mile). A tilt-bed (roll-off) truck sets it on the ground for you; a flatbed is cheaper but you must provide a forklift or crane to offload.

The line items people forget

Site prep (gravel, railroad ties or concrete piers), sales tax where applicable, a lock box for security, and any modifications — which always cost more on a rusty box than on clean one-trip steel. Budget these in from the start.

Before you pay

The 10-point pre-purchase inspection

Whether you walk the yard yourself or send someone, check these before money changes hands. Tap each item as you confirm it. A surveyor's report runs about $100–$200 and can save you thousands.

Buying remotely?

If you can't inspect in person, buy from a supplier who'll send photos of the specific unit and put the grade on the invoice — and prefer one with a verified track record. See how we score suppliers →

Get the drop right the first time

Delivery & site prep — the part buyers underestimate most

The single most common delivery failure is space. A truck needs far more clearance than the container itself. Plan the path and the pad before you book.

tilt-bed truck 20ft sliding off ~60 ft of straight, level clearance + clear overhead: no wires, branches or eaves
  1. Clear a straight, firm path

    A tilt-bed needs to back in straight and tip the bed up. Plan ~60 ft of straight clearance with room behind to tilt — not just a 20 ft parking spot.

  2. Level the ground & set a foundation

    Put the four corners on railroad ties, concrete blocks or piers on level ground. This keeps doors square and air moving under the floor so it doesn't rot.

  3. Check overhead & surface

    No low wires, branches or eaves over the drop zone. Avoid soft grass or fresh asphalt — the truck and box are heavy and will sink or scar.

  4. Decide door orientation up front

    Tell the driver which way the doors should face. Repositioning a placed 20ft is a real hassle, so get it right on the drop.

Buy safely

Container scams are real — here's what they look like

The container world has a persistent fraud problem: fake listings, "too cheap" boxes, and deposits for units that never arrive. If you see these, slow down.

Price far below market

A "$700 cargo-worthy 20ft delivered" is bait. Real CW boxes don't sell at As-Is prices.

Wire transfer or crypto only

No card, no invoice, "pay a deposit to hold it." Untraceable payment is the scammer's tell.

No physical depot or address

A real supplier has a yard you can name, call and ideally visit. Stock photos and a free email address aren't a business.

Won't show the actual unit

If they can't send photos of the specific box (with its number) or put the grade in writing, walk away.

20ft buyer questions

Frequently asked

Used 20ft boxes commonly run about $1,225–$3,000 before delivery, depending on grade and how close you are to a depot. Wind & Water Tight units sit at the low end, Cargo-Worthy in the middle, and one-trip (near-new) units typically start around $2,800. Delivery is usually separate — roughly $150–$1,550 by distance.

Cargo-Worthy is inspected and certified sound enough to be shipped overseas, so it can be exported. Wind & Water Tight is only guaranteed to keep wind and water out — great for storage, but not export-certified. If you'll never put it on a ship, WWT gives you the same weatherproofing for less money.

A standard 20ft is about 20'0" long, 8'0" wide and 8'6" tall outside, with roughly 1,170 cubic feet inside. The door opening — the number that decides what fits — is about 7'8" wide by 7'5" tall. A 20ft high cube is the same footprint but a foot taller at 9'6".

A tilt-bed truck sets the box on the ground but needs a long, straight, clear path — plan for about 60 ft of straight clearance plus room to tilt, on firm level ground, with nothing overhead. A flatbed is cheaper but you'll need your own forklift or crane to offload.

For weatherproof storage of tools or equipment, used WWT or CW is just as tough and far cheaper. For a backyard office, retail build or any conversion where looks and clean steel for cutting matter, a one-trip container is usually worth the extra.

Both share the same 30,480 kg maximum gross weight, so with dense cargo you'll hit the weight limit before filling a 40ft. For machinery, tools or aggregate — and on a tight lot — a 20ft is usually the better call.
