How Movers Estimate Volume (CBM): Understanding Your Moving Quote

What Is CBM and Why Does It Determine Your Moving Cost?

CBM stands for cubic metres, and it is the standard unit professional movers use to measure the total volume of your household goods. Your CBM figure directly determines the truck size, crew number, packing materials needed, and ultimately the cost of your move. A typical 1-bedroom apartment generates 8-15 CBM of goods, while a 4-bedroom villa can produce 40-70 CBM. Understanding how CBM is calculated helps you evaluate whether a moving quote is fair, avoid overpaying for unnecessary truck space, and compare quotes from different companies on an equal basis. Our residential moving team uses CBM-based pricing to ensure transparent, accurate quotes on every job.

Average CBM by Property Type in Dubai

These averages are based on our data from over 4,500 residential moves in Dubai. Your actual CBM may vary depending on lifestyle and furniture density.

The wide ranges reflect the huge variation in how families furnish their homes in Dubai. A minimalist couple in a 2-bedroom may have 12 CBM, while a family with children, extensive kitchen equipment, and a home office in the same apartment size may exceed 30 CBM.

How Do Movers Conduct a Volume Survey?

Professional movers estimate CBM through a pre-move survey, which takes one of three forms depending on the company and the size of the move.

In-Person Survey

An experienced surveyor visits your home and physically walks through every room, closet, storage area, balcony, and parking space. They note every item using a standardised inventory system that assigns known CBM values to common items. For example:

• 3-seater sofa: 1.5-2.0 CBM
• King-size bed (with frame and mattress): 2.0-3.0 CBM
• Dining table (6-seater): 1.0-1.5 CBM
• Standard wardrobe: 1.5-2.5 CBM
• Washing machine: 0.5-0.8 CBM
• Medium moving box (packed): 0.06-0.08 CBM
• Large moving box (packed): 0.1-0.15 CBM

In-person surveys are the most accurate method, typically within 5-10% of actual volume. They take 30-60 minutes for apartments and 60-90 minutes for villas.

Video Survey

Video surveys became standard during 2020 and remain popular for their convenience. You walk through your home on a video call while the surveyor directs you to open closets, show storage areas, and point the camera at large items. Accuracy is slightly lower than in-person surveys (within 10-15%) because the surveyor cannot feel the weight of items or see into corners as easily.

Phone / Photo Estimate

Some companies offer estimates based on a phone description and photos. This is the least accurate method (within 15-30%) and is only appropriate for very small moves (studios and 1-bedrooms with minimal furniture). For larger moves, this approach frequently leads to underestimates that result in surprise charges on moving day when the truck is too small.

Why Do Moving Estimates Vary Between Companies?

It is common to receive CBM estimates that differ by 20-40% between companies for the same home. Several factors explain this.

Different Inventory Methods

Some companies use detailed item-by-item counting while others estimate by room. Room-based estimates are faster but less precise. A surveyor who counts 47 items in your kitchen versus one who marks "kitchen — medium" will produce different numbers.

Padding for Safety Margin

Professional movers add a 10-20% buffer to their CBM estimate to account for items the surveyor missed (attic storage, items at a friend's house, last-minute purchases) and the extra volume created by packing materials. A company quoting 25 CBM and one quoting 30 CBM may actually be estimating the same household — one just includes a larger buffer.

Packing Method Differences

How items are packed affects the total CBM. Professional packing typically adds 15-25% to the raw item volume because bubble wrap, paper, and padding create airspace. An item that measures 0.5 CBM unpacked may occupy 0.6-0.65 CBM when properly wrapped and boxed. Companies that include packing in their CBM figure will quote higher than those that estimate unpacked volume.

Honesty and Experience

Unfortunately, some less reputable companies deliberately underestimate CBM to win the job with a lower quote, then charge extra on moving day when the actual volume exceeds the estimate. This is one of the red flags to watch for when choosing a mover. Always ask if the quote is binding (fixed price regardless of actual volume) or non-binding (subject to adjustment based on actual volume).

How to Ensure an Accurate CBM Estimate

Taking these steps before your survey will produce the most accurate estimate and prevent moving-day surprises.

• Declutter first: Remove items you will not move before the survey. Every item the surveyor sees gets counted. Decluttering before the survey means a lower and more accurate CBM figure
• Open everything: Open every closet, cabinet, storage room, and drawer for the surveyor. Items behind closed doors get missed
• Show all spaces: Balcony, garage, maid's room, rooftop terrace, storage cage in the building basement — every space where you store belongings must be surveyed
• Mention items elsewhere: If you have items stored at a friend's house, at the office, or in a separate storage unit, tell the surveyor. These are commonly forgotten
• Flag special items: Large, heavy, or awkwardly shaped items (pianos, safes, pool tables, chandeliers) need to be specifically noted because they require special handling that standard CBM rates do not cover
• Ask about packing volume: Clarify whether the CBM estimate includes packed volume (with wrapping and boxes) or raw item volume. This distinction explains many seemingly inconsistent quotes

CBM for International vs Local Moves

CBM matters even more for international moves because overseas shipping costs are calculated per CBM, and the rates are significantly higher than local transport.

Local Moves

For moves within Dubai, CBM determines the truck size and crew time. The cost impact is relatively moderate — an extra 5 CBM might add AED 200-500 to your quote because it means slightly more loading time or a marginally larger truck.

International Moves by Sea

Sea freight is priced per CBM, with rates varying by destination. Typical rates from Dubai:

• UK / Europe: AED 250-450 per CBM
• Australia: AED 300-500 per CBM
• India / Pakistan: AED 150-300 per CBM
• USA / Canada: AED 350-550 per CBM

An extra 5 CBM on an international move to the UK could add AED 1,250-2,250 to your shipping cost. This is why accurate CBM estimation is critical for our international moving service clients.

International Moves by Air

Air freight is priced by weight or volumetric weight (whichever is greater), not CBM directly. However, the CBM figure helps determine whether sea freight or air freight is more economical for your shipment. Our air vs sea freight guide covers this comparison in detail.

Common CBM Misconceptions

"I only have a few big items, so my CBM must be low"

Large furniture items consume significant CBM. A single L-shaped sofa can occupy 3-4 CBM, a king bed with frame 2-3 CBM, and a large wardrobe 2-3 CBM. Just three pieces of furniture can account for 7-10 CBM before you count a single box.

"Boxes don't take up much space"

The average 2-bedroom apartment produces 40-70 boxes when professionally packed. At 0.06-0.15 CBM per box, that is 3-10 CBM in boxes alone — sometimes more than the furniture.

"I can reduce CBM by disassembling everything"

Disassembly helps, but modestly. A disassembled wardrobe still occupies 60-70% of its assembled volume because the panels, shelves, and hardware still need space. The main benefit of disassembly is fitting items through doorways and elevators, not dramatically reducing volume.
