Moving Box Sizes Chart: Small, Medium, Large and Extra Large in Cubic Feet

Updated September 3, 20268 standard sizesWardrobe, dish, mirror, lamp and file boxes

Standard moving boxes run from the 1 cubic foot book box through small (1.5 cu ft), medium (3 cu ft), large (4.5 cu ft) and extra large (6 cu ft): heavy items in small boxes, light bulky items in large ones, nothing over about 50 pounds. The chart gives each size with dimensions, cubic feet, what to pack and the stocked box, plus the specialty boxes and a box count by home size.

Standard moving box sizes

Moving boxes are sold by nominal size and cubic feet, and the rule that governs them is simple: heavy things go in small boxes, light bulky things in large ones, and no box should weigh more than one person can carry down a staircase. A 1.5 cubic foot small box full of books weighs about 45 pounds; the same books in a 4.5 cubic foot large box would weigh 130. The chart lists the standard sizes with what each is for and the stocked box that matches.

Sizes are inside dimensions of the stocked 32 ECT kraft box closest to the moving-industry standard. Safe weight is a lifting guideline, not the box rating; a 32 ECT box is certified to 65 lb.

How many boxes a move needs

Typical counts for a furnished home; heavy readers and cooks need more small boxes, families with children more large ones.
Home Small Medium Large Extra large Wardrobe Dish pack
Studio or 1 bedroom 10 to 15 10 to 15 5 to 8 2 to 4 1 to 2 1
2 bedroom 15 to 25 15 to 25 8 to 12 4 to 6 2 to 4 1 to 2
3 bedroom 25 to 35 25 to 35 12 to 18 6 to 10 4 to 6 2
4 bedroom and up 35 to 50 35 to 50 18 to 25 10 to 15 6 to 8 2 to 3

Packing by box size

  1. Small boxes first. Books, papers, canned goods, tools, dishes wrapped in kraft paper; fill to the top so the box does not crush.
  2. Medium for the kitchen and closets. Pots, small appliances in their cords, folded clothes, toys; keep under 50 lb.
  3. Large and extra large for soft goods. Bedding, pillows, coats, cushions; they fill the box without weight.
  4. Tape the bottom in an H with 2 in carton sealing tape; a 55 yard roll seals about 30 boxes top and bottom.
  5. Label two sides with room and contents; stack heavy small boxes on the bottom of the truck and light large ones on top.

Strength and reuse

Moving boxes sold by carriers and truck rental companies are usually 32 ECT single wall, the same grade as the stocked shipping boxes on this chart; a double wall box (48 ECT) is worth it for books, records and anything that will be stacked in storage for months, as explained on the box weight capacity page. Boxes survive two or three moves if they are stored flat and dry between them; the reuse guide covers what to check. The full list of stocked sizes is on the box size chart, and the cubic feet chart converts any size.
