1. Inventory first, room size second
Walk through one area at a time and group standard cartons, luggage, furniture, appliances, sports equipment and awkward pieces. Record quantities, condition and retrieval priority. “One bedroom of belongings” is not a measurement: two households can use that room very differently.
- Take a clear overview photo of each group, excluding unnecessary personal information.
- Number cartons and keep a short contents list so you can locate items without opening everything.
- Flag heavy, fragile, non-stackable and dismantled pieces.
- Separate first-month essentials from items that can remain at the back.
2. Measure L × W × H
Measure the furthest outside points after packing, including handles, wheels, projections and protective material. Length × width gives the footprint; L × W × H gives volume. Equal volume does not imply equal floor area when one group cannot be stacked.
Keep units consistent and allow for measurement error. Do not count the full room height as usable automatically: weight, stability and safe retrieval usually limit the stack.
3. Test a layout, not just a total
Stacking, weight and stability
- Put stronger, heavier cartons below lighter ones.
- Use compatible carton sizes where practical and stop when a stack becomes unstable.
- A tall item must stand securely, not merely clear the ceiling.
Retrieval aisle
- Leave an aisle to frequently used groups.
- Do not trap early-retrieval cartons behind furniture.
- Allow room to turn, lift and open lids as well as space for the objects themselves.
Plot bicycles, curved furniture, long equipment and other awkward items at their real outline. Treating each as a neat cuboid can materially understate the required footprint.
4. A provisional estimation workflow
- Capture: make the inventory, photos and largest-item measurements.
- Classify: mark weight, fragility, stackability and retrieval frequency.
- Plot: sketch scaled footprints and add awkward shapes.
- Make it usable: add an aisle, door clearance and handling space.
- Compare: use the illustrative size examples; they are guidance, not confirmed room inventory.
- Verify: share the list and unresolved questions before deciding.
This is a provisional estimate, not a fit guarantee. Room shape, usable height, access route and provider rules can all change the space required.

Fictional worked example: return from volume to layout
Imagine a household with twelve matching cartons, one dismantled shelving unit, one bicycle and two chairs. They measure every packed item, flag dense document cartons as safe for only two layers, and keep weekly-use cartons at the front. Summed carton volume gives a starting number, but the scaled footprint shows that the bicycle, chair shapes and retrieval aisle consume space that the volume total hides. They therefore compare more than one layout and send the inventory to the provider.
This fictional example explains a method only. It is not a recommended room size, confirmed inventory or fit guarantee. Limiting factors still include room shape and usable height, doorway and turning clearance, lift or stair constraints, floor and shelving loads, prohibited-item rules, environmental needs and visit frequency. Check the Rama 3 planning status before enquiring because the service location, opening and room choices remain unconfirmed.
FAQ
Can total volume select a room by itself?
No. Volume omits aisles, awkward outlines, stability and handling clearance, so test a layout as well.
What percentage should I add?
There is no universal allowance. Base it on retrieval, route and actual constraints, then ask the provider to review the inventory.
Does registration book space?
No. Registration is a free expression of interest, not a booking or reservation.
Questions to confirm with any provider
Do not infer operating details from photographs or examples. Ask for written answers that match your intended move-in date:
- What is the customer-facing service address, confirmed opening date, available room inventory and current price?
- What are the access hours and staffed office hours? Is access subject to notice or identity checks?
- What security arrangements and camera coverage apply, and what remains the customer's responsibility?
- Are temperature, humidity or other environmental conditions controlled or monitored? What fire precautions apply?
- What insurance or liability arrangements should the customer make?
- What parking and loading rules apply? Are lifts or trolleys available, and what dimensions or weight limits affect the route?
- Is shelving supplied or permitted? What load limits and installation rules apply?
- Which items are accepted or prohibited, and are there packaging requirements?
- What minimum term, deposit, notice, payment and move-out conditions apply?
- Which services are actually operated by the provider, and which transport, packing, receiving or handling tasks must you arrange?
