Best for
- Estimating move size, truck size, storage size, packing supplies, cleaning cost, or local moving cost before getting quotes.
- Comparing rooms, boxes, bulky items, labor hours, access needs, supplies, mileage, and buffers with assumptions visible.
Before relying on it
Check first
- Forgetting stairs, elevators, long carries, bulky items, packing density, fragile items, access needs, peak dates, or local fees.
- Treating a room-based estimate as a guaranteed truck, storage, labor, or supply requirement.
- Comparing quotes without checking what is included: labor minimums, insurance, fuel, supplies, taxes, disposal, or service scope.

What to know before using the result
Room-based modelPlanning estimate
The estimate assigns more small boxes to heavy items and more large boxes to bulky but lighter items.
Packing styleBig swing factor
Books, kitchen goods, hobbies, linens, closets, and storage bins can change box counts quickly.
BufferReduces last-minute trips
Add a higher buffer if you have not decluttered, have many fragile items, or need extra packing paper.

Benchmarks
How to read the result
Studio / 1 bed: Lower box count.
Still sensitive to kitchen items, books, and storage closets.
2 - 3 bed: Mid-size move.
Box counts rise fast when each bedroom and shared space is packed separately.
15%+ buffer: Safer planning.
Useful if you want fewer supply runs during packing week.

FAQ
Common questions
How many moving boxes do I need?
Estimate by room count and storage areas, then add a buffer for books, kitchen items, fragile goods, and packing style.
Why split small, medium, and large boxes?
Small boxes are better for heavy items like books and dishes. Large boxes work better for bulky but lighter items.
Does this include wardrobe boxes?
No. Add wardrobe boxes, mattress bags, bubble wrap, packing paper, and specialty boxes separately if you need them.
Why add a packing buffer?
A buffer helps cover books, kitchen items, fragile goods, odd-shaped items, and the last few things that usually remain after the obvious rooms are packed.
Should I buy all boxes at once?
Use the estimate as a starting point, then adjust if you declutter heavily, already have bins, or can return unused boxes.
