How many moving boxes do I need? Counts by home size

Start from a published estimate for your home size

You need a starting number, and the published estimates broadly agree. Redfin's moving guide gives these ranges:

Use the low end if you are a light packer who has just decluttered, the high end if your closets are full. The ranges are wide on purpose: two two-bedroom apartments can hold very different amounts of stuff. The rest of this post is about where in the range you land.

Get the size mix right, not just the total

A total of 60 boxes is useless if they are all large. Box kits from packaging suppliers show the kind of mix that works. Uline's kits, for example, are built like this:

Notice two things. Medium boxes are the workhorse in every kit. And small boxes show up as soon as there is a real household to pack, because small boxes are where heavy things go.

Know what the sizes actually are

"Small" and "large" mean different things at different stores, so check dimensions. U-Haul's box guide lists its standard sizes: a 12 x 12 x 12 inch book box, a small box at about 16 x 12.5 x 12.5 inches, a medium at about 18 x 18 x 16, a large at 18 x 18 x 24 and an extra-large at 24 x 18 x 24. Its guidance on what goes where is the rule to follow: small boxes for small, dense things (tools, small appliances, canned food), mediums for kitchen gear and decor, larges for light but bulky items, extra-larges for pillows, quilts and seasonal clothing.

Count the heavy categories separately

Books, records, files, canned goods, tools and dishes are the categories that blow up a box count, because they can't go in big boxes. A large box of books is a box nobody can lift. The NIOSH lifting guidance puts the maximum two-handed lift under ideal conditions at 51 pounds, and moving is not ideal conditions. So walk your shelves and estimate these separately: a shelf of hardcovers fills roughly one small or book box. Add those boxes to the small column before you buy anything.

The kitchen needs more boxes than any other room

Kitchens are dense, fragile and full of odd shapes, which is why the larger supplier kits add dedicated dish boxes and why dish-packing kits exist at all (U-Haul's Dish Saver, for instance, is a box with a cell divider and foam pouches for plates and glasses). Budget the kitchen on its own: dishes and glasses in dish boxes or mediums with dividers, pots and pans in mediums, the pantry in small boxes. Count the cabinets, not the room.

Don't box what doesn't need a box

Some things travel better without one. Hanging clothes can go in wardrobe boxes (they're in the bigger kits for a reason) rather than being folded into ten mediums. Towels, blankets and linens can do double duty as padding around fragile things, which Atlas Van Lines recommends, so they don't need boxes of their own. Pillows and comforters can go in large bags. Every one of these is a box you don't buy, tape, carry or flatten.

Walk the house room by room before you buy

A whole-house guess hides the closets. Do a five-minute walk with a notepad: each room, each closet, the garage, the attic, under the beds, and the bathroom cabinets. U-Haul's moving supplies calculator asks for exactly this kind of detail (bedrooms, closets, bathrooms and more) because closets and storage spaces are where the surprise boxes live. Write a rough small / medium / large count per space and add it up; compare it to the range in tip 1.

Buy for the first two weeks, then top up

You don't need every box on day one. Packing goes room by room, starting with the things you use least, so buy enough for the first few rooms plus the heavy categories, and top up as you learn your own rate. Redfin's advice is to grab 10 to 15 extra boxes when in doubt, which is a sensible buffer against the last-night run.

Quality beats quantity for heavy and fragile loads

Free boxes are great for linens and pillows. For books, dishes and anything heavy, use boxes that are sturdy and the right size, with the bottom taped properly. Atlas suggests having at least three different sizes on hand, and some corrugated or extra-sturdy boxes for dishware and other fragile items. A failed bottom on the stairs costs more than the box ever saved.

Number them as you go, so the count tracks itself

The moment you start sealing boxes, write a number on each one. It gives you a live count to compare against your estimate ("we're at 38, the kitchen isn't started, buy more mediums"), and on the other end it lets you check that everything arrived. Labeling and numbering is its own small system; start it with box one.
