How many moving boxes do I need? A practical estimate

1. Why a number per square metre is not enough

Two homes of the same size can need very different quantities of boxes. Books, dishes, toys, collections and full cellar shelves need packaging; empty floor space does not. The size of the boxes also changes the count.

Treat floor-area or household-size rules as rough starting points at most. For purchasing, focus on what will actually be packed. Sort belongings first and identify items travelling in suitcases, existing containers or special packaging. Furniture is not part of the moving-box count.

2. Use sample packing to estimate your own needs

Take a suitable box for each of three groups: heavy items, mixed belongings and light items. Pack a manageable section of a shelf or cupboard as it will travel, including protective material, a closed lid and a weight that can be handled under your moving conditions.

Record what fitted into which box. Suppose one small box held the contents of two similarly filled shelf compartments. Seven comparable compartments would suggest 7 ÷ 2 = 3.5, rounded up to four small boxes initially. This only transfers to compartments with comparable dimensions and contents.

Repeat for different kinds of belongings. A book sample does not establish the kitchen or clothing count. If you change box sizes, check the assumption again.

• Record the box type and dimensions so the remaining estimate uses the same size.
• Include protective material in the trial rather than adding it after the estimate.
• Estimate heavy and fragile contents separately.
• Mark unexamined cupboards as unresolved, rather than assigning them zero boxes.

• Pack books and keep track of shelf groups

3. Combine your estimates room by room

Worked example using assumed quantities. Your actual count may be very different.

Include all rooms and storage areas. Start with an estimate and replace it with actual counts as you pack. Boxes already packed form part of the requirement; do not add them a second time.

The following figures are hypothetical results of an imaginary inventory. They are not a recommendation for any floor area, number of people or household size.

4. Count small, regular and large boxes separately

An order for “40 boxes” is incomplete without sizes. Smaller boxes are often more practical for compact heavy belongings; larger ones suit light, bulky items. OBI also explains this distinction in its packing guide.

Follow the assembly instructions and load rating of the specific box. A printed rating is not a personal carrying target: a structurally adequate box can still be too heavy for the intended carrying route. Agree manageable packed weights with your helpers or partner.

List wardrobe boxes, picture packaging and other special formats separately. Do not automatically convert them into a number of ordinary boxes.

5. Separate spares from unexamined belongings

Spare boxes help with last-minute small items or boxes that become unusable. An unexamined cellar is an unresolved part of the inventory and should be counted separately. Do not hide major uncertainties in a standard allowance.

The example adds four spare boxes to the recorded 34: 34 + 4 = 38. Four is an assumption for this example, not a universal percentage rule. Whether more material must be obtained immediately also depends on timely resupply.

Keep spares flat and dry until needed. Check purchase or loan return conditions in advance; do not assume unused boxes can be returned free of charge.

6. Subtract available boxes by size

For each size, subtract suitable owned and borrowed boxes from the requirement. If the result is negative, the additional requirement for that size is zero.

Count your own boxes and confirmed loans by size. Check bases, folds, handles, moisture and odour. Damaged or unsuitable boxes are not available stock. A packed box belongs in both the requirement and the available-box count.

Here the total of 38, including spares, is split across three sizes. All twelve owned and six borrowed boxes are assumed suitable and available in time.

• Total check: 38 − 12 − 6 = 20 additional boxes.
• Surplus large boxes do not automatically replace missing small book boxes.
• If the partner supplies material, confirm its type, quantity, timing and price.

7. Update the count while packing

After each completed room, record boxes packed, contents still to pack and suitable empty boxes remaining. This reveals optimistic sample estimates or spare stock early.

Identify a first-evening box and count it exactly once. Its packaging requirement depends on whether you use a cardboard box, bag or existing suitcase. Keep essential belongings accessible.

For vehicle planning, the partner also needs box dimensions, furniture and heavy individual items. The box count is neither your entire moving volume nor a promise that one trip will suffice.

• Estimate moving volume from furniture and boxes
• Pack and label moving boxes
• Prepare the whole move step by step

8. Enquire about packing and materials through a partner

Provide quantities by size and explain whether you will pack yourself, only need materials or want a packing service. Boxes, protection, delivery, collection and any loan conditions should be distinguishable in the specific quote.
