The 20-ft high-cube: a foot taller.

A 20-ft high-cube is exactly what it sounds like. Take the 20-ft footprint you already know and add a foot of height, 9 feet 6 inches on the outside instead of the standard 8 feet 6 inches. It's a real difference once you're standing inside one. It's also a size we don't keep sitting in the yard. We sell the standard 20-ft and the 40-ft high-cube off the lot regularly. A 20-ft high-cube is a specialty size we source to order when a job genuinely calls for it.

If that's you, the honest first step is a phone call, not a form. Tell us what you're trying to fit and why the height matters, and we'll tell you straight whether a 20-ft high-cube is realistic on your timeline, or whether a different size gets you there faster.

What a 20-ft high-cube actually is.

"High-cube" isn't a marketing label, it's a real ISO container class. A 20-ft high-cube is still a genuine ISO shipping container, built the same way as everything else we sell, it's just built a foot taller. Nothing about the steel, the floor, or the doors changes because of that extra foot, only the height.

Length and width stay put. A 20-ft high-cube is 20 feet long and 8 feet wide, the same footprint as the standard 20-ft. Height is the only thing that changes, 9 feet 6 inches instead of 8 feet 6 inches, a full foot taller.

Floor space doesn't grow with it. You're still working with roughly 160 square feet, the same as a standard 20-ft. That's worth saying plainly, because it's easy to assume a taller box also means a bigger footprint. It doesn't. The extra foot stacks straight up, not out.

• The steel and floor are the same as every container we sell, 14-gauge Cor-Ten weathering steel with a marine-grade plywood floor underneath.
• Cargo doors on one end that seal tight, just like a standard 20-ft.
• Expect roughly the same outdoor lifespan as the rest of our stock, somewhere around 30 years without needing real upkeep.

Because the length and width match a standard 20-ft, placing one works the same way a standard 20-ft delivery does. The one thing worth a second look is overhead clearance. The box itself sits a foot taller than what you might be picturing, so low branches, carport headers and power lines are worth checking before delivery day. A photo of the drop spot ahead of time usually settles it either way.

What that extra foot actually buys you.

A single extra foot seems small on paper. Standing inside a 20-ft high-cube, it's the difference between ducking under the doorway and walking through like it's a normal room. It shows up most on the days you're moving something bulky through the door or reaching for the top shelf without a stepstool.

• Headroom under a finished ceiling. Insulate and line the inside and you still have real standing room left, instead of a box that felt tight before you even started building.
• Shelving mounted above head height. One more foot of wall means one more usable shelf run without giving up any floor space.
• Taller equipment stored upright. Anything that needs a little more vertical clearance than a standard 20-ft allows has a real shot at standing instead of lying on its side.
• A small workshop you're not stooping in. Build out a shop in a tight footprint and that extra foot is the difference between a space you want to work in and one you put up with.

Picture the difference in a small footprint. Two shelves mounted at head height in a standard 20-ft can feel like they're closing in on you. In a high-cube, that same shelving sits with air above it, and the room still feels like a room instead of a crawl space.

None of that changes what fits on the floor. It changes what fits above it.

Who actually needs this size.

A 20-ft high-cube makes sense for a specific kind of job: a tight lot or a short driveway that can only take a 20-ft footprint, paired with a real reason to want more than 8 feet 6 inches of height inside it. Think a small workshop conversion where you'll insulate and finish a ceiling, tall shelving in a spot with no room to build out sideways, or a piece of equipment that simply won't sit upright under a standard height.

If none of that describes your situation and you just want more room in general, look at the standard 20-ft or the 40-ft high-cube instead. The 40-ft high-cube gets you the same extra foot of height plus a lot more length, and because it's a size we actually keep in stock, it's the easier box to get your hands on.

This also comes up when someone already has a 20-ft spot locked in, maybe a pad that's already poured or a gate opening that won't take anything wider or longer, and the only lever left to pull is height. If the footprint is fixed and the ceiling is the actual problem, the high-cube is the size worth asking about.

Our 20-ft vs 40-ft guide covers the general size decision in more depth. This page is only about the height question.

Why sourcing one takes a call, and a little patience.

Here's the honest part. A 20-ft high-cube is genuinely uncommon in the used market, especially next to a 40-ft high-cube. Most of the surplus high-cube stock moving through depots and brokers is 40-ft, because that's where the shipping volume is. A 20-ft high-cube is a much smaller slice of what's out there.

That doesn't mean it's impossible, it means it takes more work on our end. We don't carry this size the way we carry the standard 20-ft or the 40-ft high-cube. When someone wants one, we go looking, and depending on what's moving through the market that week, it can take longer to land the right unit.

When you call about a 20-ft high-cube, expect a real conversation, not a script. We'll ask what you're storing, why the height matters for your job, and how firm your timeline is. That tells us whether it's worth starting the search or whether a size we already have solves the same problem today.

• We'll tell you honestly what's realistically available when you call.
• Condition and timing depend on what turns up, not a fixed list we're sitting on.
• If a unit is slow to find, we'll say so instead of leaving you guessing.

We'd rather tell you that up front than take your call, go quiet, and leave you wondering. If a 20-ft high-cube is genuinely what the job needs, we'll go find one. If timing matters more than the extra foot, we'll say so and point you toward a size that's easier to get moving on.

The honest next step.

Two things are true at once here. A 20-ft high-cube is a real, useful size when the job calls for it, and it's also one we don't have sitting around waiting. Both are worth knowing before you set your heart on one.

A 20-ft high-cube is a specialty size for us, not something sitting on the lot ready to go. We source it to order, and the fastest way to find out what's realistic is a call, not a web form.

Call (276) 237-6144 and tell us what you're trying to fit and why you need the extra foot. We'll tell you honestly what's out there right now, roughly what to expect on timing, and whether the standard 20-ft or the 40-ft high-cube might solve the problem faster instead.

We'd rather have that conversation up front than let a web form set expectations we can't back up. It's a phone call, not a commitment, and it's the fastest way to get a straight answer.
