Moving Box Calculator
Running out of boxes mid-move is a nightmare. Running to the store three times is worse. Select your home size and clutter level to get exact counts for small, medium, large, and wardrobe boxes, plus tape, packing paper, and estimated costs. Be prepared from day one of packing.

Box Count Formula
Total Boxes = Base Count × Clutter Multiplier × Garage Multiplier
Our base counts come from professional mover data across thousands of moves. The clutter multiplier adjusts from 0.75 (minimalist) to 1.35 (packed). Having a garage or storage area adds 15% more boxes for tools, seasonal items, and stored goods.
What Goes in Each Box Size
| Box Size | Dimensions | Best For | Weight Limit |
|---|---|---|---|
| Small (1.5 cu ft) | 16×12×12" | Books, canned goods, tools, records | 50-65 lbs |
| Medium (3 cu ft) | 18×18×16" | Kitchen items, toys, small appliances | 45-65 lbs |
| Large (4.5 cu ft) | 18×18×24" | Bedding, pillows, lampshades, towels | 35-45 lbs |
| Wardrobe | 24×20×46" | Hanging clothes, coats, dresses | 50-75 lbs |
Real-World Example
A 3-bedroom home with average clutter and a garage:
- Base: 35 small + 30 medium + 15 large + 3 wardrobe = 83 boxes
- Clutter multiplier (average): × 1.0
- Garage multiplier: × 1.15
- Adjusted: 40 small + 35 medium + 17 large + 3 wardrobe = 95 boxes
- Tape: 6 rolls × $5 = $30
- Packing paper: ~48 lbs × $3 = $144
- Total supply cost: ~$350
Box Estimates by Home Size
| Home Size | Small | Medium | Large | Total |
|---|---|---|---|---|
| Studio / 1 Bedroom | 15 | 12 | 5 | 33 |
| 2 Bedroom | 25 | 20 | 10 | 57 |
| 3 Bedroom | 35 | 30 | 15 | 83 |
| 4 Bedroom | 50 | 40 | 20 | 114 |
| 5+ Bedroom | 65 | 55 | 30 | 156 |
Common Packing Mistakes
- Heavy items in large boxes. Books, tools, and canned goods should always go in small boxes. A large box of books can weigh 100+ lbs — unmovable and likely to break.
- Not labeling boxes on multiple sides. Label the top and at least one side with room destination and contents. This saves enormous time when unloading.
- Packing an "essentials" box last. Pack a clearly marked box with toilet paper, phone chargers, medications, snacks, coffee maker, and bedding last so it's loaded last and unloaded first.
- Skipping the inventory list. Number each box and keep a simple list (Box 1: Kitchen - pots and pans). This is invaluable for insurance claims if anything is damaged.
- Overloading wardrobe boxes. They're tall and top-heavy — pack only hanging clothes, not shoes or heavy items at the bottom. They tip over easily when overloaded.

Frequently Asked Questions
How many moving boxes do I need?
A good rule of thumb is 10-15 boxes per room. A studio/1-bedroom needs about 30-35 boxes total. A 2-bedroom needs 50-60. A 3-bedroom needs 75-85. A 4-bedroom needs 100-115. These estimates include small (books/heavy items), medium (kitchen/general), and large (linens/light bulky items) boxes. Adjust up if you're a collector, have a packed garage, or haven't decluttered.
What size moving boxes do I need?
You need three main sizes: Small (16×12×12" / 1.5 cu ft) for books, tools, canned goods, and heavy items. Medium (18×18×16" / 3 cu ft) for kitchen items, small appliances, toys, and general items — this is your workhorse box. Large (18×18×24" / 4.5 cu ft) for bedding, pillows, lampshades, and lightweight bulky items. Never put heavy items in large boxes — they become impossible to lift.
Where can I get free moving boxes?
Liquor stores (sturdy, divided boxes), grocery stores (banana boxes are strong), Costco/warehouse stores, Facebook Marketplace (people giving away post-move boxes), Craigslist free section, recycling centers, office supply stores, and bookstores. Ask early in the week — stores often flatten boxes after weekend restocking. Used boxes are fine for moving as long as they're dry and structurally sound.
How much packing paper and bubble wrap do I need?
Budget 3-5 lbs of packing paper per box of kitchen items and 1-2 lbs for general boxes. For a 3-bedroom home, that's approximately 50-75 lbs of packing paper. Bubble wrap is mainly needed for mirrors, framed art, electronics, and very fragile items — 100-200 feet for a typical home. Alternatively, use clean towels, t-shirts, and socks as free padding for dishes and glasses.
How much tape do I need for moving?
Each box uses approximately 3-4 feet of tape (bottom seal, top seal, and H-pattern for heavy boxes). For 80 boxes, that's about 320 feet of tape, or roughly 5 standard rolls (55 yards/165 feet each). Buy one extra roll — running out of tape mid-packing is frustrating. Use 2-inch wide packing tape, not masking tape or duct tape, which don't seal well on cardboard.
How many wardrobe boxes do I need?
One wardrobe box holds approximately 2 feet of hanging closet rod space (about 12-15 garments on hangers). Count your closet rod footage: a standard 6-foot closet needs 3 wardrobe boxes. Wardrobe boxes are expensive ($8-15 each), so use them for delicate, wrinkle-prone items (suits, dresses, coats) and use large boxes with tissue paper for casual clothes.
Should I buy new or used moving boxes?
Used boxes work fine for a local move. They're free or cheap and environmentally friendly. For long-distance or storage moves, buy new boxes — they're stronger, stack evenly (same sizes), and reduce risk of pest contamination. Never use used boxes that have been wet, have pest evidence, or are crushed on corners. New box cost for a 3-bedroom: approximately $100-200 for all sizes.
