Moving Box Calculator: 45 Boxes Total, 5-Room Move
On the defaults — 5 rooms at 8 boxes a room, with 5 spare boxes — a move needs 45 boxes total, and 5 tape rolls. This is the moving box tool: multiply the rooms by the boxes per room for the room boxes, add the spares for the total, and divide by ten for the tape — a move guessed from the rooms alone tells you nothing until the spares behind it are known.
What does 45 boxes total, 5 tape rolls mean?
It means a five-room home, packed at eight boxes a room, fills forty boxes, and with five spare boxes for the awkward last items the order is forty-five boxes, sealed with five rolls of tape at one roll per ten boxes. The rooms set the room boxes, the boxes per room set the fullness inside each room, and the spares set only the total: a spare box never fills a room, it only covers the lamp, the plants, and the drawer that would not fit anywhere else. The only judgement is the boxes per room — 8 is a planning figure, and the count that settles the move is the one the actual rooms fill, not the one the floor plan suggests.

Three things to check before you trust the number
First, check the rooms honestly: 5 rooms must be the rooms actually packed, not the rooms on the listing — a garage, a hallway cupboard, and a garden shed all fill boxes, and a move counted short by a room runs short by eight boxes. Second, check the boxes per room against the fullest room, not the emptiest: 8 suits an average bedroom, while a kitchen or a book-filled study fills twelve or more, and an average borrowed from the tidiest room understates the whole move. Third, check the spares against the awkward items, not against optimism: 5 spares cover lamps, plants, and odd drawers, and a move with no spares at all always ends with a trip to the shop on packing day.
Worked example
5 rooms, 8 boxes a room, 5 spare boxes. Room boxes: 5 × 8 = 40 boxes. Total: 40 + 5 = 45 boxes. Tape: 45 ÷ 10 = 4.5, rounded up to 5 rolls. In practice that means a five-room move takes forty-five boxes and five rolls of tape — the number to order before packing starts, with the spares covering the last awkward items.
Every branch, checked
With 7 rooms instead of 5, the total rises to 61 boxes — 7 tape rolls. With 10 boxes a room instead of 8, the total rises to 55 boxes — 6 tape rolls. With 0 spare boxes instead of 5, the total falls to 40 boxes — 4 tape rolls. With 3 rooms instead of 5, the total falls to 29 boxes — 3 tape rolls.
The reverses, worked backwards
The rooms behind 45 boxes are 5: at 3 rooms the total is 29 boxes (3 tape rolls); at 7 rooms it is 61 boxes (7 tape rolls). The boxes per room behind 45 are 8: at 6 a room the total is 35 boxes (4 tape rolls); at 10 a room it is 55 boxes (6 tape rolls). The spare boxes behind 45 are 5: at 0 spares the total is 40 boxes (4 tape rolls); at 10 spares it is 50 boxes (5 tape rolls) — the spares never touch the rooms, only the total.
What the defaults assume
The defaults assume 5 rooms packed at a true 8 boxes a room, with 5 spares for awkward items and one tape roll per ten boxes. They do not assume a garage, a shed, or a storage unit — a home with a packed garage, a full loft, or a garden shed needs more boxes than 45, so treat 45 as the house count, not the property count.
Who uses this
- A family planning a move: the 45 boxes settle the order before packing starts.
- A renter moving flats: the tape rolls are the line for the shop trip, not a guess.
- A mover costing a job: the room boxes are the line to compare across homes by size.
- A household decluttering first: the spares are the line for what survives the clear-out.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the room count, the true boxes per room, and the spares. Real moves vary with fullness, books, and awkward items — so treat 45 as the planning order for a five-room home at a true 8 boxes a room with 5 spares, and check it against the fullest room before ordering.

Frequently asked questions
How many moving boxes for a 5-room house?
45 boxes on the defaults: 5 × 8 = 40 boxes from rooms, plus 5 spares = 45 boxes, sealed with 5 tape rolls.
Why add spare boxes at all?
Because every move has items that fit nowhere: lamps, plants, loose drawers, and the contents of the junk drawer. Spares are cheaper bought with the order than bought singly on packing day.
How many tape rolls per box?
About one roll per ten boxes, the figure used here: 45 boxes need 4.5 rolls, rounded up to 5. Heavy boxes taped top and bottom use more — add a roll for a book-heavy move.
Does the garage count as a room?
Yes, if it holds things being moved: count every space that fills boxes — garage, shed, loft, and hallway cupboards — or the order runs short by exactly those spaces.
What if one room is far fuller than the rest?
Then raise the boxes per room, not the rooms: a kitchen or a book-filled study at 12 boxes a room lifts the total by the extra boxes in that room alone, which is exactly how the calculator treats it.
How is this different from the moving cost calculator?
That page prices the move in dollars; this page counts the boxes for packing. Use that page for the budget, this page for the order.
