Measure each item's length, width, and height in feet, multiply the three figures, and add every item together to get your total cubic feet, or run a room-by-room inventory through a moving volume calculator for the same result. That number is genuinely useful for sizing a truck and comparing quotes side by side, but it will not replace the written, FMCSA-compliant estimate an interstate mover owes you. Start with a room-by-room count tonight, or use the calculator template below.
TL;DR:
- Measure and itemize your belongings accurately, treating irregular shapes and disassembled furniture as their smallest rectangular bounding boxes.
- Expect typical cubic-foot ranges for a household size to identify potential under- or over-estimates before requesting quotes.
- Confirm whether your move will be priced by weight or volume, and always get a written explanation of volume-to-weight conversion from the mover.
- Use a detailed inventory with room-by-room specifics and access conditions to ensure you compare identical estimates from different moving companies.
- Avoid accepting volume-only estimates for interstate moves unless they are explicitly bound and based on an in-person or virtual inspection.

How to calculate cubic feet: formulas and quick methods
The formula behind every cubic-feet moving estimate is simple: length times width times height, in feet, equals cubic feet. If your tape measure gives you inches, divide the result by 1,728, since a cubic foot equals 12 by 12 by 12 inches.
Here's how that plays out with real furniture:
- A standard sofa measuring 7 feet long, 3 feet deep, and 3 feet high comes to 63 cubic feet.
- A queen mattress and frame at 6.5 feet by 5 feet by 1.5 feet adds roughly 49 cubic feet.
- Twenty medium moving boxes, each averaging 3 cubic feet, contribute 60 cubic feet.
Add those three lines and you already have 172 cubic feet before you've touched a dresser, a dining table, or a single kitchen box. That is the value of building the estimate item by item rather than guessing at a whole-house number.
One cubic foot equals 1,728 cubic inches, which is why any measurement taken in inches needs that conversion before it gets added to a feet-based total. Skipping it is the single most common arithmetic error in a DIY estimate.
For large, uniform items like sofas and dressers, measure each one individually. For a houseful of smaller, repetitive items, a lookup table or online calculator that assigns average volumes to common household goods saves time and is accurate enough for planning purposes. Round every measurement up to the nearest half foot rather than down. A cubic-feet estimate is a planning tool, not a substitute for the number a mover will record once your goods are actually loaded.
Measuring irregular shapes, disassembled furniture, and nested items
Odd shapes and stacked boxes throw off a lot of first-time estimates, but a few habits keep the math honest.
- Treat every irregular item, whether it's a curved armchair or an L-shaped desk, as if it fits inside the smallest rectangular box that would fully contain it, then use that box's dimensions.
- Measure bulky furniture assembled when it will travel assembled, and measure it disassembled when you plan to break it down, since disassembly can shrink the footprint but adds packing time.
- Roll rugs and measure the resulting cylinder's length and diameter rather than guessing at flat square footage.
- Mattresses and box springs should be measured flat and added individually, since they rarely compress and often get double-counted or forgotten.
- Electronics and anything fragile deserve their original box dimensions plus a few extra inches per side for padding, since a bare screen measurement will undercount the space it actually needs in the truck.
Pro Tip: When boxes are already packed, measure a sample of each size (small, medium, large) once, then multiply by how many of each you have instead of remeasuring every single box.
Typical cubic-feet benchmarks by home size
A rough benchmark helps you sanity-check your own total before you send it to anyone. These ranges assume a normally furnished home rather than a minimalist or heavily stocked one, and they climb fast once a garage, basement, or storage unit enters the picture. Heavy boxed items, like books or tools, add weight faster than they add volume, which matters once you get to pricing.
| Home size | Typical cubic feet range |
|---|---|
| One-bedroom apartment | A moderate volume range typical for a one-bedroom apartment |
| Two-bedroom apartment or small house | A moderate volume range typical for a two-bedroom apartment or small house |
| Three-bedroom house | A moderate volume range typical for a three-bedroom house |
| Four-bedroom or 3,000+ sq ft house | A higher volume range typical for a larger house |
If your itemized total lands well outside these bands, recheck your measurements before you request quotes. A number that's too low almost always means missed boxes or forgotten garage and storage items.
Volume vs weight: how movers price moves and what regulations require
Cubic feet decide your truck size. Whether it decides your bill depends on the type of move you're booking. Full-service interstate moves typically price by weight, while container services, some regional carriers, and partial-load shipments often price by volume instead. When a mover uses volume to build your estimate but bills by weight, they're required to explain that conversion to you in writing rather than leave it as a black box.
That written explanation matters because of how FMCSA structures estimates for interstate household goods moves:
- A binding estimate guarantees the total cost for the exact quantities and services listed, regardless of the final weight or volume loaded.
- A non-binding estimate is not a guaranteed price, and it can shift once your goods are actually weighed or measured.
- Both types should be based on an actual or virtual inspection of your belongings, not a phone guess.
A written, itemized estimate is the strongest protection a mover of household goods offers you under federal guidance, and it's the document that turns your DIY cubic-feet number into something enforceable. Before you sign anything, ask directly whether the estimate is binding or non-binding, and get any volume-to-weight conversion explained in plain language on paper.
Turn your cubic-feet total into comparable quotes with an inventory checklist
A cubic-feet number only helps you if every mover you contact is quoting against the same inventory. Otherwise you're comparing apples to guesses.
Build your inventory around these fields for every room:
- Item name, dimensions in feet, and estimated cubic feet.
- Box count by size (small, medium, large, wardrobe).
- Major appliances and specialty items, such as pianos, safes, or gym equipment.
- Photos of anything unusually large, fragile, or disassembled.
Then attach the site conditions that change labor time and access, even though they don't change your cubic-feet total:
- Stairs, elevators, and whether either building has a working one.
- Long carry distance from the truck to your door.
- Parking restrictions or required permits at either address.
Send that same package to each mover and ask specifically for a written estimate, along with whether it will be binding, based on an FMCSA-outlined inspection. Reviewing licensing details is also worth doing before you compare a single price, since the FTC advises verifying DOT registration and steering clear of any company that leaves prices or terms blank. Our guide to interstate move documents walks through exactly what a compliant estimate should include.
How Value Added Moving turns a cubic-feet plan into a booked move
Once your inventory is built, the next step is matching it to a mover who will honor it. Value Added Moving runs an inventory audit against your cubic-feet estimate, arranges a virtual or on-site survey, and negotiates quotes across its vetted network so the volume-to-weight conversion is explained rather than assumed.
- A move coordinator is available as a single point of contact for the process from quote to delivery.
- Estimates are reviewed for hidden fees before finalizing the agreement.
- The movers in the network are licensed, insured, and pre-screened.
Submit your room-by-room inventory and request a virtual survey to see how your numbers translate into an actual quote.
Common mistakes worth avoiding
The estimates I see go wrong in the same few places: undercounting boxes, forgetting accessorials like stairs or a long carry, and accepting a volume-only quote for an interstate move without asking whether it's binding. Fix those three and your written estimate will hold up far better on moving day.

FAQ
How much would it cost to move a 3,000 sq ft house?
Cost depends on distance, weight, and the services booked, so there's no single published figure that applies to every 3,000 sq ft home. A house that size typically falls in the higher end of the cubic-feet ranges covered above, which is the number worth handing to movers for a written estimate rather than relying on a square-footage guess.
How many cubic feet are in a 26 ft moving truck?
Moving truck capacity varies by manufacturer and box height, so the exact figure depends on the specific truck a mover assigns you. Ask your mover directly for that truck's rated cubic-foot capacity so you can compare it against your own itemized total.
What size moving truck for 1000 cubic feet?
A total near the typical range for a three-bedroom house fits the truck sizes commonly used, based on the benchmark ranges above. Confirm the exact rated capacity with your mover, since truck interiors vary by model and box configuration.
Do movers charge by cubic feet?
Some do, particularly for container services, partial loads, and certain regional moves, while full-service interstate moves are usually priced by weight. Whichever method your mover uses, ask for a written explanation of how volume and weight are converted before you accept the quote.
