What fits in a container? Build a measured storage inventory

Measure the item as it will be stored

Measure after deciding what will be dismantled, boxed or wrapped. A table with its legs removed is a different storage item from an assembled table. Include protective packaging, handles or projections that remain attached. For irregular shapes, enter the enclosing rectangular dimensions and label that as an envelope rather than solid material volume.

Use a separate line for each item type with the same packaged dimensions and mass. Ten identical boxes can share a line; two cabinets with different dimensions should not. The tool uses millimetres for dimensions and kilograms for mass. A blank mass is retained as unknown rather than treated as a weightless item.

• Length: along the container in the intended storage orientation.
• Width: across the container and door opening.
• Height: upright height, including the packaging or support already measured.
• Quantity: the number of identical packaged items on that line.
• Floor position: record whether the item must stand directly on its own part of the floor. Any other arrangement still needs review.

Use volume, floor area and door checks together

Boxed volume adds length × width × height for every item. It is useful for comparing versions of an inventory, but empty spaces between shapes and space for access still matter. A volume below the container's rectangular capacity does not establish a workable arrangement.

The unstacked floor area places every item on its own footprint. That can exceed the container floor even when the total volume looks modest. The separate floor-only figure shows only items you explicitly said must have their own floor position. An unknown answer remains unresolved. A fragile item that cannot support a load might itself be placed on a suitable support, so that is a different question from whether it must occupy the floor.

The upright door check compares the entered width and height with the reference opening. It flags obvious dimensional conflicts in that orientation. It does not rotate an item, check whether it can turn after entry, allow for a ramp or prove that the floor can carry it.

A small example explains the difference

Suppose you have ten packed boxes, each 600 × 400 × 400 mm. Their combined boxed volume is 0.96 m³ and their floor area is 2.4 m² if every box stands separately. Those two values answer different questions. The volume stays the same if you stack boxes, but the floor space may change.

Now add a fragile cabinet that must stay upright and, for this example, must have its own floor position. Its floor footprint must remain available regardless of the spare height above it. Without a checked arrangement and a stacking limit for the boxes, dividing total volume by a container's capacity would give a misleading container recommendation. This inventory deliberately does not make that leap.

Choose the access routine before filling the floor

For a house move with one loading and one unloading, you may be able to group items by the order in which they will be needed. For business stock, putting frequently used items behind long-term storage can create repeated unloading work. Mark the items you need to reach and leave a practical retrieval route in the plan you discuss with the supplier.

Add the space needed to inspect walls, keep ventilation usable and protect vulnerable goods from contact with steel. No universal percentage is added by the calculator: a narrow stack of identical boxes and a mixed furniture inventory do not lose the same amount of usable space. Use a drawing or an actual arrangement review for the final decision.

Delivered container or storage at an operator's site?

A container delivered to your land needs a suitable site, delivery access and an agreed unloading arrangement. You control day-to-day access, subject to your own site arrangements, and need to plan collection at the end of hire. The space available for the delivery vehicle is separate from the container's final footprint.

Storage at an operator's premises has its own access hours, loading arrangements, permitted goods and contract terms. Confirm whether you can bring a vehicle to the door, whether any handling equipment is offered and who provides insurance. A room, pod or wooden crate should be compared using its own clear dimensions; this tool's dry-container examples are not a specification for those services.

Resolve the longest, heaviest and least flexible items first

Sort your questions by what could rule out an option. A single long object, a tall upright cabinet or a heavy machine can matter more than the total number of boxes. Identify those items for the supplier and confirm whether dismantling or a different door arrangement is possible before ordering the unit.

Keep the complete text inventory for your own review. The quote link transfers a short overview, including unknown masses and the number of dimension warnings, rather than silently truncating an item list and pretending it is complete. The downloadable record retains all rows. Update it if the packing method or quantity changes.

• Check the largest items against the actual unit's internal and door dimensions.
• Confirm packaging, orientation and any dismantling requirements.
• Resolve stackability and the need to reach individual items.
• Identify missing masses, heavy point loads and handling requirements.
• Agree the service, duration, permitted contents and moisture protection.
• Ask the supplier to review the layout; do not order from a volume ratio alone.
