How the estimate works
The calculator starts with a bedroom baseline, adds household members, adjusts for kitchen volume, then reduces the result when a real declutter pass is likely. Treat the number as a shopping range, not a guarantee, because books, pantry goods, hobbies, storage closets, and fragile wrapping can change the count quickly.
Manual adjustment rules
- Add 3-5 medium boxes for a deep closet, storage cage, or balcony storage area.
- Add 2-4 small boxes for books, tools, files, weights, pantry cans, or dense dishware.
- Add 1-3 large boxes for bedding, towels, pillows, lampshades, and light bulky items.
- Add 10-20% if fragile items need paper, dividers, or extra void fill.
- Do not subtract for decluttering until unwanted items have actually left the home.
Box mix examples
| Move profile | Small | Medium | Large | Extra note |
|---|---|---|---|---|
| Minimal studio | 4-6 | 8-12 | 2-4 | Works only when kitchen and closet volume are light. |
| Average one-bedroom | 8-12 | 16-24 | 5-8 | Confirm books, desk items, and cookware before buying. |
| Two-bedroom with normal kitchen | 12-18 | 28-40 | 8-14 | Add buffer for kids, hobbies, linens, and storage. |
| Family home | 20+ | 45+ | 15+ | Inventory by room before booking labor or supplies. |
Calculator record log
After packing, compare the calculator result with the final box count. Record bedrooms, people, kitchen intensity, declutter level, estimated boxes, final boxes used, and unused boxes in the Field Notes Template. If the final count differs by more than 20%, write which zone caused the gap before reusing the estimate for another move.
| Field | Record | Why it matters |
|---|---|---|
| Estimated boxes | Small, medium, and large counts from the calculator. | Creates a baseline to compare against reality. |
| Final boxes used | Count sealed boxes by size after packing. | Shows whether the estimate was high, low, or close. |
| Cause of gap | Kitchen, books, closet, storage, hobby gear, or fragile wrapping. | Improves the next estimate without pretending the first result was exact. |
Before you buy
Run the estimate, compare it with a room-by-room count, then buy a small buffer rather than a huge bundle. If you can return unused boxes locally, keep the receipt and avoid opening extra packs until needed.
