How many boxes and packing supplies will you need?

You grabbed 20 moving boxes from the liquor store, started packing the kitchen, and ran out halfway through the cabinets. Now it's 9 PM, Home Depot is closed, and you're loading loose pots into garbage bags. The mistake? Eyeballing the count instead of calculating room by room.

This estimator breaks down box needs by room type, stuff level, and fragility. The result tells you exactly how many small, medium, large, wardrobe, and dish boxes to buy — plus tape, bubble wrap, and packing paper quantities. Use it to make one trip to the store, not three.

Small boxes (1.5 cubic feet) are for heavy stuff: books, tools, canned goods, small appliances. Keep them under 30 lbs so you can actually lift them. Most people underestimate how many small boxes they need.

Medium boxes (3 cubic feet) are the workhorse. Clothes, toys, linens, kitchen gadgets — if it's not too heavy or too fragile, it goes here. Plan for these to be 40-50% of your total box count.

Large boxes (4.5-6 cubic feet) are for light, bulky items: pillows, comforters, lampshades, stuffed animals. Never fill these with heavy items — they'll split at the seams or be impossible to carry.

Wardrobe boxes have a hanging bar inside. They keep clothes wrinkle-free and save you from folding everything. One wardrobe box holds about 2 feet of closet rod worth of clothes.

Dish boxes (also called dish packs) have cell dividers for dishes, glasses, and stemware. They cost more but prevent breakage. If you have a full kitchen, you'll need 3-5 dish boxes.

Kitchen: 10-15 boxes total. Kitchens need the most small boxes (for pantry items) and dish boxes (for glassware). Budget 3-5 dish boxes, 4-6 small boxes, and 4-6 medium boxes for an average kitchen.

Bedroom: 8-12 boxes each. One wardrobe box per closet, plus 3-5 medium boxes for clothes and 2-3 small boxes for books or electronics. Master bedrooms run higher.

Living room: 8-12 boxes. Mostly medium and large boxes for decor, books, and electronics. Add small boxes if you have a lot of media (DVDs, games, cables).

Bathroom: 2-4 boxes. Small and medium boxes for toiletries and towels. This is the easiest room to pack.

Step 1: Add each room you need to pack (bedroom, kitchen, living room, etc.) with a label like "Master Bedroom" or "Kids Room."

Step 2: For each room, select stuff level (light, average, heavy) based on how full the room is.

Step 3: Select fragility level (few, some, very fragile) based on how many breakables you have in that room.

Step 4: Add a buffer (10-20%) for items you forgot and packing inefficiency. Review the totals.

Situation: David is packing a 2-bedroom, 900 sq ft apartment. He has a full kitchen with lots of dishes, average furniture, and a home office corner. He wants to know how many boxes to buy.

Result: David needs approximately 64 boxes: 18 small, 28 medium, 10 large, 2 wardrobe, 6 dish boxes. Plus 50 feet of bubble wrap, 320 sheets of packing paper, and 10 rolls of tape. Total supplies cost: about $150-200 if bought new, or $50-75 if he sources used boxes.

Packing tape: Budget 1 roll per 6-8 boxes. You'll use it for sealing, reinforcing bottoms, and labeling. Buy the wide, heavy-duty kind — cheap tape splits under weight.

Bubble wrap: 2-3 feet per fragile item. Dishes, glasses, electronics, picture frames, and mirrors all need it. A 100-foot roll covers most 1-2 bedroom moves.

Packing paper: 5-10 sheets per box for padding and wrapping. It's cheaper than bubble wrap and better for filling gaps. A 25-lb bundle (about 500 sheets) handles a typical apartment.

Markers and labels: Label every box with room and contents. You'll thank yourself when you're unpacking and need to find the coffee maker.

Free boxes: Liquor stores (sturdy dividers), bookstores (small boxes), grocery stores (produce boxes), and Craigslist/Facebook Marketplace (people giving away post-move boxes).

Cheap boxes: U-Haul and Home Depot sell individual boxes for $1-4 each. Buy in bundles of 10-20 for discounts. Walmart and Amazon sell moving kits that bundle boxes, tape, and paper.

Rent reusable boxes: Companies like BINS rent plastic moving bins for $100-200/week. They're sturdier than cardboard and stack better in the truck. Good for local moves where you can return them quickly.
