RandoziMoving Box Estimator
List your rooms, then give each one a volume of loose belongings and the number of books, plates, glasses, shoes, clothes and linens. You get the number of boxes per room, the split into small, medium and large boxes, and a total with a safety margin you choose.
Boxes to prepare
48 boxes
Rooms
Up to 12 rooms. Empty fields count as 0. Counts are whole numbers; the volume is the space your loose things take, in cubic metres.
| Room | Small | Medium | Large | Total |
|---|---|---|---|---|
| Kitchen | 1 | 9 | 1 | 11 |
| Living room | 7 | 7 | 2 | 16 |
| Bedroom | 2 | 7 | 7 | 16 |
| All rooms | 10 | 23 | 10 | 43 |
Box assumptions
Rule-of-thumb values, not measurements of your boxes: change them to match yours. The shares only say how the loose belongings are split between small, medium and large boxes; they are relative, so 1, 3 and 1 means the same as 20, 60 and 20.
Boxes per room = ceil(volume × boxes per m³) loose boxes, plus each item type ÷ its items per box (fractions of the same size added, then rounded up). The margin is applied to each size and rounded up. Furniture, wardrobe boxes and packing materials are not counted. Nothing you type leaves your browser.
How it works
- Set the boxes per cubic metre and the safety margin at the top. The defaults are a rule of thumb you can change.
- For each room, type the volume of loose belongings in m³ and the counts of books, dishes, glasses, shoes, clothes and linens.
- Add or remove rooms. Read the total with the margin, the split by box size and the table by room.
- Change the items per box or the small, medium and large shares if your boxes or your habits differ, then copy the summary.

Questions
- How is the number of boxes calculated?
- For each room, loose belongings give ceil(volume × boxes per m³) boxes, shared between small, medium and large boxes by the shares you set. Each type of item fills its own box size: count ÷ items per box, with the fractions of the same box size added up and then rounded up to a whole box. The margin is then applied to each size and rounded up. With 0.4 m³ at 15 boxes per m³, that is 6 loose boxes.
- Where do the items per box and the boxes per m³ come from?
- They are rule-of-thumb values, not measurements of your boxes: 25 books in a small box, 20 plates or bowls and 24 glasses in a medium one, 10 pairs of shoes in a medium one, 40 folded garments and 20 towels in a large one, and 15 boxes per cubic metre of loose belongings. Heavy things go in small boxes so they stay liftable. Change any of them to match your own boxes.
- What is the safety margin for?
- Packing always takes more boxes than planned, because of awkward shapes, fragile items and last-minute finds. A margin of 10 % adds one box for every ten, rounded up per size. Set it to 0 to see the bare estimate.
- What does this page not cover?
- Furniture, wardrobe boxes, mirrors, artwork and appliances are not counted, nor are wrapping paper, tape or bubble wrap. It is an estimate from the figures you type, and nothing you type leaves your browser.
