How Many Boxes Do I Need to Move?
Roughly 25–30 boxes per bedroom, about 86 for a three-bedroom home. Full room-by-room counts, box types, and the 15% rule nobody follows.

A three-bedroom home takes 70–95 boxes. A two-bedroom takes 45–65. A four-bedroom takes 100–130. Add 20–30 for a full garage and 8–12 dish packs for a china cabinet. Whatever count you use, include the garage — which is where most online calculators quietly go wrong. Below: the room-by-room breakdown, how to adjust the numbers for your own house, and the mistakes that cost people money.
Why the calculator you just used is wrong
Every box calculator online asks for bedrooms or square footage, because that is all a web form can capture. Both are poor predictors, and the second is worse than the first.
What actually determines box count is density — how full the cupboards are, which is mostly a function of how long you have lived there. A 1,500 sq ft home owned since 1996 routinely needs more cartons than a 2,600 sq ft home owned since 2019. A small, full home can easily take longer than a larger, sparse one.
The second failure is scope. Most calculators price the living space and stop. They do not ask about the garage, the Arizona room, the shed, the loft or the walk-in pantry — and in the West Valley those are frequently the densest spaces on the property. A number that omits your garage is not 10% low. It can be 30% low.
Box counts by home size
Use these as a starting point, then apply the density adjustment two sections below. If you would rather not estimate at all, ask a packing provider to suggest a mix when they quote. See materials and supplies.
Room by room — the detailed breakdown
This is the table to actually work from. Counts are for a typical three-bedroom home at average density; scale each room to what you have.
| Room | Small | Medium | Large | Specialty | Notes |
|---|---|---|---|---|---|
| Kitchen & pantry | 8–10 | 6–8 | 1–2 | 4–6 dish packs | The slowest room in any house. Tinned goods in smalls only. |
| Living / family room | 4–6 | 5–7 | 2–3 | 1–2 mirror cartons | Books in smalls; cushions and throws in larges. |
| Dining room | 2–3 | 2–3 | — | 4–8 dish packs | China, glass and serving pieces drive this room. |
| Primary bedroom | 3–4 | 5–6 | 3–4 | 2–4 wardrobes | Hanging clothes go in wardrobe boxes, not folded. |
| Second / third bedroom | 2–3 | 4–5 | 2–3 | 1–2 wardrobes | Children’s rooms: toys are bulky not heavy — use larges. |
| Bathrooms | 2–3 | 2–3 | 1 | — | Liquids bagged separately, upright, in a lined carton. |
| Home office | 5–7 | 3–4 | 1 | 1 lay-flat | Paper is dense. Smalls only, and do not over-fill. |
| Linen & hall cupboards | 1–2 | 2–3 | 3–4 | — | Excellent void fill — keep some back for the fragiles. |
| Garage & shed | 10–14 | 6–10 | 2–4 | — | Tools and hardware in smalls. This is the room people forget. |
| Arizona room / patio | 2–3 | 3–4 | 2–3 | — | It is a room. Count it. |
| Loft / bonus room | 2–3 | 3–4 | 2–3 | — | Not a bedroom, not on any calculator, usually full. |
Rough working ratio: 40% small, 35% medium, 25% large, plus specialty. Almost everybody buys this backwards — too many larges, not enough smalls — because larges look like better value per box and are the ones you regret.
Adjust for your own house in sixty seconds
Start from the size band above, then walk your house and answer these six. Each one moves the number.
| Question | If yes | Adjustment |
|---|---|---|
| Have you lived here more than ten years? | Density compounds quietly | +15–25% |
| Is the garage or shed more than half full? | It is a room, not storage | +20–30 boxes |
| Is there an Arizona room, loft or bonus room? | Rarely counted anywhere | +7–10 boxes |
| Do you have a china cabinet or display shelving? | Dish packs, not mediums | +8–12 dish packs |
| More than four bookcases? | Books are dense and go in smalls | +6–10 smalls |
| Walk-in pantry or second fridge/freezer? | Modern kitchens hold far more | +4–6 boxes |
Two or more “yes” answers and you should be planning from the top of your band rather than the middle. Four or more and you are probably a band above where the bedroom count puts you.
The five mistakes that cost real money
- Books in large boxes. The commonest and most expensive error. A large carton of books can pass 80 lb, which fails the box, hurts whoever lifts it, and risks everything underneath it. Books go in 1.5 cu ft smalls, always.
- Toys in small boxes. The exact inverse. Toys are bulky and light — they belong in larges. Most households get both of these backwards at once.
- Skipping dish packs. A standard medium is single-walled. A dish pack is double-walled with cell dividers. This is not an upsell; it is a different product, and it is the one material genuinely worth paying for. See how to pack fragile items.
- Under-filling. A half-empty box is not a light box, it is a box whose contents will move for the entire journey. A lot of breakage traces back to this. If it rattles when tilted, it is not finished.
- Buying everything in one trip. Everyone over-estimates the first time. Buy in two rounds — and, where you can, from a supplier that takes unopened flat boxes back.
Which box does which job
| Carton | Size | Use it for | Never use it for |
|---|---|---|---|
| Small / book box | 1.5 cu ft | Books, tools, tinned food, records, paper | Anything bulky — you will need twice as many |
| Medium | 3.0 cu ft | General contents, kitchen goods, small appliances | Books — too heavy at this size |
| Large | 4.5 cu ft | Bedding, pillows, lampshades, toys, soft goods | Anything dense. Weight is the whole risk. |
| Dish pack | 5.2 cu ft, double wall | China, glass, stemware — with cell dividers | Ordinary contents — you are wasting the box |
| Wardrobe | With hanging rail | Hanging clothes, straight off the rail | Folded clothing — use a large instead |
| Mirror carton | Adjustable, flat | Framed art, mirrors, glass tops — on edge | Anything that must lie flat |
| Lay-flat / TV | Adjustable | Flat panels, large artwork | Stacking anything on top of it |
50 lb is the sensible ceiling for any single carton. Anything heavier should have been split across two smaller ones — a rule that eliminates most box failures and most moving-day back injuries at the same time.
How many boxes do I need — questions
How many boxes for a 3-bedroom house?
70–95 for the living space, plus 20–30 if the garage is full and 8–12 dish packs for a china cabinet. Long tenure pushes you to the top of that range or past it.
How many boxes for a 2-bedroom apartment?
45–65, and usually toward the lower end since apartments rarely have a garage or an Arizona room.
What size boxes do I need most of?
Smalls. A workable ratio is 40% small, 35% medium, 25% large. Most people buy the reverse and end up with cartons too heavy to lift.
Is it cheaper to get free boxes?
For non-fragile, low-weight contents, free boxes are fine. Grocery and liquor boxes have usually already been wet or compressed once, so do not trust them with anything heavy or breakable.
Do I need dish packs, or will regular boxes do?
You need dish packs for china and glass. A standard carton is single-walled and offers no cell separation. This is the one material where the cheap option reliably costs more.
What if I buy too many?
Buy in two rounds anyway.
Do I need boxes at all if you are packing?
It depends on the provider — ask whether materials are included in the rate or billed separately. Boxes, dish packs, wardrobes, mirror cartons, paper, bubble and tape. See the cost page.
