How Many Moving Boxes Do You Need?

Start with home size, then adjust for how full the home is, the number of people and the types of things you own.

Why bedroom count is only a starting point

A two-bedroom flat with built-in storage can contain less than a crowded one-bedroom flat. Treat room count as a baseline, not the answer. Books, kitchen equipment, hobby materials, children’s belongings and garage contents often move the estimate more than the floor plan.

Build a mixed box plan

Use smaller boxes for dense items such as books and canned food, medium boxes for most household goods, and larger boxes mainly for light bulky items. A mixed set is easier to carry and usually packs a vehicle more efficiently than using one size for everything.

Add a controlled buffer

A buffer of roughly 10–15% is usually more useful than buying a huge surplus. Keep some boxes unassembled until needed, and check the return policy where you buy supplies.

Try these quantities in the Moving Box Calculator, then adjust them to your inventory.

Worked planning example

For an average two-bedroom home with three people, the baseline is 40 boxes: 12 Small, 18 Medium, 8 Large and 2 Wardrobe/specialty. Choosing Full increases the total to 50: 15 Small, 23 Medium, 10 Large and 2 Wardrobe. Add a real room-by-room inventory before ordering, especially for books and hobbies.

Common mistakes

• Counting bedrooms but overlooking an occupied garage.
• Assuming the wardrobe allocation exactly matches your hanging clothes.
• Buying every box before trial-packing one cupboard.
