If you are wondering what size truck you need when moving, start with what you are taking rather than how many bedrooms you have. Two three-bedroom homes can differ by a factor of two in load, depending on furniture, books, tools and whatever is hiding in the garage, so bedroom counts are a rough sense-check rather than a measurement.

This article gives you a worksheet method you can complete in an evening or two. You declutter, inventory each room, convert furniture and boxes into cubic metres, compare the total with typical ranges for your home size, and then confirm vehicle capacity with your removalist before you book. The aim is simple: avoid paying for empty space, and avoid leaving belongings behind.

Declutter First, Then Build Your Room-by-Room Inventory

Before measuring anything, sort your belongings into four piles: move, sell, donate and dispose of. Only confirmed moving items go on the worksheet, and if something is undecided, flag it with a note rather than guessing, so it cannot quietly inflate or shrink your estimate.

Set up one worksheet with these columns: room, item or box type, quantity, transport dimensions, total cubic metres, and notes on dismantling, weight or stacking restrictions. Then work through the house in order.

Leave out fitted furniture and appliances staying with the property, and estimate boxes room by room from what is actually there rather than giving every room the same allowance. Mark provisional counts clearly and replace them with real packed counts as the move approaches.

Turn Furniture Measurements and Box Counts Into Cubic Metres

For each item, multiply length × width × height in metres, then multiply by the quantity. Convert centimetres to metres before you calculate, and keep sensible rounding until the final total so small errors do not pile up.

Measure furniture in the shape it will travel. Record dismantled bed components, detached table legs and separated sofa modules rather than assuming everything goes on assembled, and list mattresses separately. For irregular pieces, measure the outer envelope as a practical starting estimate, and flag cavities, protrusions and fragile surfaces for your removalist instead of assuming every gap can hold something else.

For boxes, use external dimensions and count by size. A 0.50 × 0.40 × 0.40 m carton occupies 0.08 m³, so ten occupy 0.8 m³. If you have not finished packing, trial-pack one representative cupboard or shelf and scale up to estimate how many cartons the rest will need, allowing for protective material inside the boxes and using smaller cartons for dense contents such as books.

Total the furniture, appliances, loose items and boxes for each room, then add the room subtotals. Do not count boxed contents again as loose belongings, and do not add a general room allowance on top of an itemised list, or you will double-count and overestimate.

Sense-Check Your Total Against Your Home Size

Once you have a total, compare it with broad planning ranges for your type of home. These are assumptions to prompt a second look, not measured industry averages or vehicle recommendations.

The volume ranges already include furniture and packed boxes, so the box counts are not an extra load to add on. Carton sizes vary, so always use your own measured box volumes.

Use the comparison to review your inventory, not to override your measurements. A surprisingly low total may mean you left out kitchen contents or stored belongings, while a high one may simply reflect extra furniture, a collection or a full garage. Sparse and heavily furnished homes can fall outside these bands, and bedroom count alone cannot establish truck capacity.

What Size Truck Do You Need When Moving? Match the Load to Usable Capacity

Compare your cubic-metre total with the vehicle's usable cargo capacity, not its external dimensions or a bedroom-based label. It is worth asking whether the quoted capacity allows for any fitted equipment or internal obstructions such as wheel arches. A truck-size guide on choosing the right size truck for your move is a useful reference for relating an estimated household load to vehicle options, though it does not replace confirmation of the actual truck being sent.

A pure volume match is rarely enough, because furniture wrapping, awkward shapes, safe loading positions and items that cannot support boxes on top all create unusable space. Rather than applying a universal percentage, ask the removalist what allowance suits your particular inventory.

It also pays to separate volume from payload. A load can fit spatially and still exceed the vehicle's legal carrying limit in kilograms, so flag dense items such as books, tools, safes and gym equipment.

Finally, check the largest item by comparing its dimensions, in its permitted orientation, with the cargo interior and the loading-door opening. Then confirm access at both properties, including driveway width, turning space, parking and any height restrictions.

Get the Load and Vehicle Confirmed Before Booking

Send your removalist the dated inventory, total estimated cubic metres, box counts by size, bulky-item dimensions and clear photographs. Note which counts are provisional, what you plan to dismantle, which items are heavy, and anything that cannot be stacked.

Then ask them to confirm that the proposed vehicle can carry the whole inventory within both usable space and payload limits, with access constraints considered. If photographs leave any doubt, request a video or in-person assessment, which matters most when your estimate sits close to a vehicle's limit or when a second trip would be impractical.

Resolve the uncertainty rather than defaulting to the smallest or the largest option, and if belongings or box counts change before moving day, update the inventory and pass it on. An agreed, current load gives the removalist a firm basis for avoiding both a vehicle that is too small and paying for space you never use.
