Cubic Feet Size Guide for International Moves (US Edition)

How Many Cubic Feet Do You Need to Move? A US Sizing Guide

Ask a freight forwarder for a quote and the first question back is almost always “How much volume are you shipping?” Most people guess low, not from carelessness but because a home you’ve lived in for years looks smaller than it measures. You scan the rooms and think, it’s not much, a few boxes and some furniture, maybe 300 cubic feet. Then the crew arrives, starts wrapping and stacking, and the real number turns out to be a third higher than the guess.

Everything here is stated directly in cubic feet, the unit most Americans actually think in. The CBM figure appears alongside it only where you’ll need it: on the quote itself. Most international forwarders, including ones serving US customers, still price and book in CBM.

The One Conversion You Need

One cubic metre (CBM) equals 35.3 cubic feet. That’s the whole conversion.

One more reference point worth keeping: a standard large moving box, the size most interstate and international movers use by default, holds about 4.5 cubic feet. That’s roughly 0.13 CBM. Stack seven or eight of them and you’ve filled one cubic metre. That single mental image, a stack of eight boxes, is the anchor for everything that follows.

US Moving Box Sizes in Cubic Feet

Before the room-by-room tiers, it helps to know what a box actually holds, because “how many boxes” is the question most people ask before they ask about furniture.

A useful rule of thumb: dense items belong in small boxes so the box stays liftable, and bulky-but-light items belong in large boxes so you’re not wasting cardboard on air. Weight, not just volume, is why movers hand you three box sizes instead of one.

The At-a-Glance Sizing Table

100–180 Cubic Feet: The Minimal Move

This is the shipment of someone who has made a deliberate call: I’m taking what I can’t replace and starting fresh with everything else. No furniture, typically. Maybe a folded mattress topper. Definitely not a couch or a dining table.

What actually fits in 100–180 cubic feet:

• 2 large suitcases or duffel bags of clothing (roughly 14–21 ft³ total)
• 8–12 medium boxes: books, keepsakes, kitchenware you won’t replace, framed photos
• Bedding compressed into vacuum bags (roughly 10–14 ft³ compressed)
• A handful of meaningful items: a lamp, a couple of small artworks, a guitar case
• Documents and electronics in a carry-on, which don’t count toward shipped volume at all since they travel with you

Who ships at this size: people moving into furnished housing at the destination, remote workers who’ve been living out of bags for a year already, anyone whose partner is already there with a home set up. This is a focused commitment, not a small one. The temptation to add “just one more box” is real at this stage. Resist it unless the item is irreplaceable at your destination.

250–350 Cubic Feet: Studio or Selective 1-Bedroom

By this range, furniture is doing most of the volume work, not boxes. You’re keeping the pieces that defined how you actually lived, not every piece you own.

What actually fits in 250–350 cubic feet:

• Bedroom: queen mattress (~35–42 ft³), flat-pack bed frame or headboard only (~14–21 ft³), one bedside table, clothes in 3–4 wardrobe boxes
• Living room: a loveseat or single armchair (~53–70 ft³), small coffee table, a TV up to 65″ boxed (~11–18 ft³)
• Kitchen: 4–6 boxes of pots, pans, glassware, and the small appliances used daily
• Office: laptop in a carry-on, maybe a monitor and desk lamp in a padded box
• Everything else: 8–12 boxes of books, clothing, and miscellany

Who ships at this size: a single professional leaving a studio and keeping only what mattered, a couple where one partner’s furniture stays behind and the other’s comes along, someone who rented furnished for years but built up a real layer of personal belongings on top. This range sits comfortably inside LCL pricing. Sharing a container at this volume is standard; the per-cubic-foot rate here is close to what it would be at either end of this tier.

350–450 Cubic Feet: 1-Bedroom, Full Contents

This is where most single-person and couple moves from a 1-bedroom apartment land, once you’re taking the majority of the contents, furniture and all. At this volume, a forwarder stops asking what you’re bringing and starts asking what you’re leaving.

What actually fits in 350–450 cubic feet:

• Bedroom: queen mattress and base (~53–71 ft³), headboard, two bedside tables, a small chest of drawers or wardrobe (~35–53 ft³), 5–6 wardrobe boxes
• Living room: a 3-seater sofa (~71–88 ft³), armchair (~28–35 ft³), coffee table, TV up to 75″ boxed (~14–21 ft³), a TV unit or bookshelf
• Dining area: a table for four, folded or dismantled (~18–28 ft³), plus four stacked chairs (~28–35 ft³)
• Kitchen: 6–8 boxes covering the full kitchen you’re keeping, stand mixer included
• Everything else: 12–16 boxes of books, clothing, personal effects, and any plants you’re allowed to bring (biosecurity rules vary sharply by destination country, so check before you pack them)

Who ships at this size: a person or couple who’s been in the apartment two-plus years, long enough to accumulate a full furniture set and a real second layer of possessions. Settled, not minimalist. This still fits comfortably inside LCL: sharing a container doesn’t affect handling or insurance, it just means your goods travel alongside other shipments headed the same direction.

450–700 Cubic Feet: The 2-Bedroom Home

This is the volume of a 2-bedroom apartment or house moving with most of its contents. The question changes here. It is no longer whether everything fits in a shared container. It is whether every item that would fit is worth the per-cubic-foot cost of shipping it, versus the cost of buying an equivalent at your destination.

A move in this range almost always forces a real sorting conversation. The guest room furniture, worth shipping? The six-seat dining table, will it even fit the new place? The books, all of them, or only the ones you can’t replace?

What actually fits in 450–700 cubic feet:

• Primary bedroom: king or queen mattress and base (~64–78 ft³), bed frame, two bedside tables, chest of drawers, a wardrobe if flat-pack (~53–71 ft³), 6–8 boxes of clothes and personal items
• Second bedroom: single or double mattress and base (~28–42 ft³), bed frame, small wardrobe or chest, 4–5 boxes
• Living room: a 3-seater plus a 2-seater or a pair of armchairs (~106–141 ft³ combined), coffee table, TV and unit, bookcase, floor lamp
• Dining room: table for six (~28–42 ft³) plus six stacked chairs (~42–53 ft³)
• Kitchen: 8–10 boxes, full contents
• Home office: desk (~14–21 ft³), office chair (~11–18 ft³), monitor, files, books
• Everything else: 10–15 boxes of personal items, art, linens, seasonal gear, kids’ belongings

Who ships at this size: a couple or small family from a 2-bedroom home who’ve stayed put for several years, or parents where the second bedroom was a nursery. This tier is where the shipment starts nudging the LCL/FCL crossover, covered below, so it’s worth pricing both options once you’re past roughly 530 cubic feet.

700+ Cubic Feet: The 3-Bedroom Home

Once you’re past 700 cubic feet, you’re into 3-bedroom-and-up territory, and the range widens with how selective you are. A carefully edited 3-bedroom move takes the main furniture from all three bedrooms, the living room suite, and full kitchen contents. That typically lands between 780 and 1,060 cubic feet. A full, unsorted home where nothing stays behind can reach 1,240 to 1,590 cubic feet or more.

Here’s the number that matters most at this tier: a 20-foot container has roughly 880 to 990 cubic feet of usable packing volume once real-world loading is accounted for. If your estimate is landing anywhere near that range, get a quote for a full 20-foot container alongside your LCL quote. At this volume, FCL frequently costs about the same as LCL per unit of volume, and you get sole custody of the container, with no shared handling at origin or destination.

What actually fits in a selective 780–1,060 ft³ move:

• Primary bedroom: king bed complete (~71–88 ft³), two bedside tables, large wardrobe (~71–88 ft³), chest of drawers, 8–10 boxes
• Bedroom 2: double or queen bed and base (~53–71 ft³), wardrobe, 4–6 boxes
• Bedroom 3 / kids’ room: single bed and base (~28–42 ft³), bookcase, desk, 4–6 boxes of books, toys, clothes
• Living room: a full sofa suite (~141–177 ft³), TV and entertainment unit, bookshelves, floor lamps, art
• Dining room: table for eight (~35–53 ft³) plus eight stacked chairs (~53–71 ft³)
• Kitchen: 10–12 boxes, full contents including appliances
• Home office: desk, chair, equipment, files, 5–8 boxes
• Everything else: 12–18 boxes of linens, seasonal clothing, sporting goods, garden items, art

Who ships at this size: a family of three or four making an international relocation, people who’ve owned a home long enough to accumulate the furniture and belongings that go with it. The question by this point isn’t “how much?” anymore. It’s “what stays behind?”

What Adds Cubic Feet Without Adding Value

Before you finalize any estimate, flag the items that eat volume out of proportion to what they’d cost to replace at your destination.

• Cheap flat-pack furniture. A basic assemble-yourself bookcase costs maybe $80 to replace new. Shipping it internationally costs more than that per unit of volume. Leave it.
• Large appliances. Washers, dryers, large refrigerators, and dishwashers are expensive to ship, and equivalent appliances usually cost less locally than the combined freight, insurance, and installation. You’ll also need to verify voltage and frequency compatibility at the destination.
• Mattresses. A queen mattress runs 35–42 cubic feet. A quality replacement at most destinations costs less than the freight to ship the old one. Exception: high-spec mattresses, orthopedic or custom-sized, where replacement cost is steep.
• Garden and outdoor equipment. Lawnmowers, patio furniture, and tools face biosecurity restrictions in many countries. Replacement cost almost always beats freight plus insurance plus potential biosecurity treatment.
• Wine and spirits. Import duty and excise on alcohol run steep in many destinations, sometimes exceeding several hundred percent of value once every charge is combined. Not worth the volume or the paperwork.
• Every single book you own. Books are dense. A box of books can hit its weight limit long before it hits its volume limit, and weight adds its own freight charges on ocean shipments at high density. Ship the ones you can’t replace. Donate the rest.

How Cubic Feet Affect What You Pay

For LCL shipments, freight is priced per unit of volume, so the accuracy of your estimate directly sets the accuracy of your quote. Underestimate, and you get a surprise invoice once the shipment is measured at origin. Overestimate, and you’ve budgeted for space you didn’t need.

Once your estimate is pointing toward a full container, the LCL vs FCL guide covers the crossover calculation in more depth, including how it shifts by route and season.

Per-unit rates vary by route, season, and market conditions. On a typical US-to-Southeast-Asia route, ocean-freight-only LCL rates generally fall between $2.30 and $5.10 per cubic foot, before port charges, customs, and local handling. The exact rate depends on origin port, season, and how easily your shipment consolidates with others heading the same way. At 400 cubic feet, that’s somewhere between $920 and $2,040 in ocean freight alone, before the rest of the charges that make up a full quote.

Past roughly 530 to 640 cubic feet, it’s always worth requesting an FCL quote alongside the LCL quote. A 20-foot container has around 880 to 990 cubic feet of usable packing volume. If your shipment is 640 cubic feet and the FCL rate is competitive, the unused 240 to 350 cubic feet of extra room may still cost less than paying LCL per cubic foot on exactly what you have.

How to Estimate Your Cubic Feet Before You Quote

Step 1: List your furniture with dimensions. Measure each large item, beds, sofas, wardrobes, tables, in feet, or look up standard dimensions if you haven’t measured yet. Multiply length × width × height for each piece, then add them up.

Step 2: Count your boxes and estimate their volume. If you haven’t packed yet, walk each room and estimate how many boxes the contents would fill. Use the box table above: small boxes run about 1.3 cubic feet, medium about 3 cubic feet, large about 4.5 cubic feet, wardrobe boxes about 13.4 cubic feet.

Step 3: Add 10 to 15 percent for packing inefficiency. Nothing packs perfectly. Furniture has awkward shapes, fragile items need extra padding, and gaps between boxes add up. Multiply your calculated total by 1.1 to 1.15.

Step 4: Send your forwarder a video walkthrough. A five-minute phone video lets an experienced forwarder estimate volume remotely with real accuracy. Walk slowly through every room, open closets, show the garage, and pan across shelves. Most established forwarders will ask for this on any shipment above roughly 280 to 350 cubic feet.

There’s a predictable gap between how a room feels and how much it actually holds. You experience your home as open space: the air, the walkways, the light coming through a window. A packed container is the opposite, dense and gap-free, measured by exactly how much your belongings displace once boxed and stacked. So the estimate that comes back often feels too high, not because it’s wrong, but because daily life in a room hides how much volume that room truly contains. The fix isn’t a more careful guess. It’s measuring the objects instead of trusting your impression of the space.

Worked Example: A 2-Bedroom Household

The household: a couple with one child, moving from a 2-bedroom apartment. Primary bedroom with a queen bed, second bedroom set up as a nursery/office hybrid, a modest living room, and a kitchen they’ve used daily for four years.

516 cubic feet lands squarely in the 2-bedroom tier from the table above and inside LCL territory, just short of the roughly 530 to 640 cubic foot range where FCL starts becoming competitive. If this household had kept the second bedroom as a full guest room instead of a nursery/office hybrid, or added a second armchair and a bookshelf, the total would likely cross 600 cubic feet and be worth an FCL comparison quote. That’s the practical value of running the math item by item instead of eyeballing a room and guessing: it tells you not just your number, but how close you are to the next pricing decision.

To turn the worked example into money, apply the per-cubic-foot range from the pricing section to the 516 cubic feet. Ocean freight alone comes to roughly $1,190 to $2,630, before port charges, customs and local handling. Then run the one comparison that decides the next step. The same household with its second bedroom kept as a full guest room crosses roughly 600 cubic feet, which at the same rates is $1,380 to $3,060. Those 84 extra cubic feet cost $190 to $430, so one decision about a spare bedroom is worth that much, and it also moves you from “LCL is clearly right” to “ask for an FCL quote.” The wrong turn is to stop at the total. Price pieces instead: each 10 cubic feet adds $23 to $51 in ocean freight, so the 78 cubic foot sofa carries roughly $180 to $400 on its own. Set that next to what the sofa would cost to replace at your destination, and the keep-or-sell call rests on a number you can check. These figures are ocean freight only, which makes them the floor of each piece’s real cost. Confirm the rate for your own route against a written quote before you decide.

Frequently Asked Questions

How many cubic feet do I need to move a 1-bedroom apartment?

A 1-bedroom apartment moved with most of its contents, furniture included, typically runs 350 to 450 cubic feet. At the low end you’re taking the essentials and leaving anything bulky or easily replaced. At the high end you’re taking most of the furniture and the bulk of your possessions. The exact number depends on furniture size, box count, and how selective you are.

How do I convert cubic feet to CBM for an international quote?

Divide cubic feet by 35.3 to get CBM. A standard large moving box holds about 4.5 cubic feet, so 35 cubic feet, or 1 CBM, holds roughly 7 to 8 large boxes stacked neatly. Most international forwarders quote in CBM even for US customers, so keep both numbers handy when you’re comparing quotes.

How many cubic feet for a 3-bedroom house move?

A 3-bedroom house moved selectively takes the main furniture from all three bedrooms, the living room suite, and full kitchen contents. That typically comes to 780 to 1,060 cubic feet. A full, unsorted 3-bedroom home where nothing stays behind can reach 1,240 to 1,590 cubic feet. Above roughly 530 cubic feet it’s worth pricing a 20-foot container against LCL.

What’s the difference between LCL and FCL for a US household move?

LCL, less than container load, means your goods share a container with other shipments and you pay per cubic foot (or per CBM, since that’s how the rate is usually built). FCL, full container load, means you pay a flat rate for the whole container regardless of how full it runs. LCL suits most household moves up to roughly 530 to 640 cubic feet. Above that, a 20-foot FCL container often becomes cost-competitive.

How do I calculate the cubic feet of a piece of furniture?

Measure length, width, and height in feet, then multiply the three figures. Example: a sofa 7.2 feet long by 3 feet wide by 2.8 feet high equals 60.5 cubic feet. For irregular shapes or furniture you’ll disassemble, use the dimensions of the largest assembled piece, or the dimensions of the crate it ships in.

What happens if my move measures more cubic feet than I estimated?

Your shipment still moves, but the invoice is based on the volume measured after packing, not your original estimate. The extra volume is normally billed at your quoted per-unit rate. A large enough gap can also push you past the LCL/FCL crossover point. That changes the entire pricing structure, and it’s the argument for a video survey before you commit to a number.

How many cubic feet fit in a 20-foot and 40-foot shipping container?

A 20-foot container holds roughly 880 to 990 cubic feet of usable packing volume once real-world loading is accounted for. A 40-foot high-cube holds roughly 2,120 to 2,370 cubic feet. If your estimate is approaching 530 cubic feet, ask for FCL pricing alongside LCL. The crossover arrives sooner than most people expect.
