Standard Moving Box Sizes

Every carton below is stocked, sold by the bundle, and priced live on its own product page. Cubic capacity is calculated from the inside dimensions so you can size a move by volume instead of guessing at box counts.

Single Wall, Double Wall and What ECT Actually Tells You

ECT stands for Edge Crush Test — a measure of how much crushing force the board takes on its edge before it fails. It is the number that matters for stacking, which is what kills cartons in a move or in storage, and it is printed in the box maker’s certificate on the flap of a shipping carton.

  • ECT-32 single wall — one fluted layer between two liners. The standard grade for general moving and shipping cartons, used on every rectangular size we stock from 12 x 12 x 10″ up to 24 x 18 x 24″.
  • ECT-48 double wall — two fluted layers. Used on our wardrobe cartons, which are tall, get hand-carried loaded, and take a hanger bar under load.
  • 51-ECT double wall — the dish pack grade, for the one carton in a move that is guaranteed to be full of fragile, heavy, irreplaceable objects.

The practical rule: match the grade to how the carton will be handled, not to what goes in it. A light load in a tall carton that gets stacked four high still needs the stronger board.

A note on stacking

Board strength is a fresh-carton figure. Corrugated loses a significant share of its stacking strength once it has been loaded, taped, opened and stored in a humid space — which is why a stack that was fine on moving day can slump after a month in a garage. If cartons are going into long-term storage, step up a grade and cut the stack height.

Wardrobe Boxes

A wardrobe carton is a portable closet: clothes transfer on their hangers, travel upright, and get hung again at the other end without ever being folded. All three of our upright sizes are double wall ECT-48 with a write-on panel and hinged hand holes, five to a bundle.

Add a steel hanger bar (20″ or 24″, rated 150 lbs, sold 50 to a case) so the garments hang instead of piling in the bottom of the carton. Hotels, uniform services and theatre companies buy the bars by the case and reuse them indefinitely.

Dish Pack Boxes and Partition Kits

Breakage in a move is almost always kitchenware, and almost always because plates were packed flat in a single-wall carton with nothing between them. The dish pack exists to stop that.

  • 18 x 18 x 28″ dish pack — 51-ECT double wall corrugated, 5.2 cubic feet, hinged hand holes and pre-printed fragile warnings, five per bundle.
  • Dish pack partition kit — three interlocking partition sets plus two layer pads, sized for the 18 x 18 x 28″ carton. Sold as one kit per box.
  • Newsprint sheets — clean 15 x 20″ newsprint for wrapping. Use unprinted sheets, not newspaper, unless you enjoy washing ink off china.

Pack plates and platters on edge, one per cell, each wrapped individually. Glasses and stemware go in the upper tier. Then fill every remaining void — a cell with movement in it is a broken plate waiting for the first pothole.

Mirror, Artwork and Picture Boxes

Framed pieces travel on edge, never flat, in a carton that is barely thicker than the frame. Our mirror cartons are a two-piece telescoping system so the finished box adjusts to the piece instead of leaving it to rattle inside something oversized.

MH-USA four-piece mirror box panel for building a telescoping art carton

Four-piece mirror panels

Four corrugated panels build a telescoping carton around any piece between 30 x 40″ and 40 x 60″ — the answer for odd-size art and framed glass.

Before it goes in the box

Tape the glass face with a large X of painter’s tape so a break stays contained, pad the corners, and mark which way is up. Then keep the carton vertical for the whole move — a mirror box laid flat and stacked on is the single most common way framed glass gets destroyed.

Telescoping Boxes for Long and Awkward Items

Floor lamps, rolled rugs, curtain rods, banner stands, tripods, artwork and anything else that is long in one dimension does not fit a rectangular carton. Telescoping boxes solve it with an inner box that slides inside a slightly larger outer box, so the finished length adjusts to the item and the carton closes tight around it.

  • Inner and outer boxes are sold separately and ordered as a pair.
  • ECT-32 single wall, in bundles of 15 to 20 depending on size.
  • Stocked pairs run from 10 x 6 x 57″ and 10 x 10 x 48″ up through 12 x 12 x 48″ and 10 x 10 x 72″.
  • The outer box is a half inch larger in each cross-section dimension so the two slide without crushing — 12 1/2 x 12 1/2 x 48″ pairs with the 12 x 12 x 48″ inner.

Blankets, Bubble and Packing Materials

Moving blankets

Quilted textile pads for furniture, appliances, cabinets and freight — reusable, and far cheaper over time than replacing what they protect. All are 72 x 80″ and sold six to a case, in four grades:

  • Economy — 21.4 lbs per case, heavyweight reusable pads for general protection.
  • Standard — 37.2 lbs per case, cotton/poly woven faces with 100% linear batting and zigzag stitching.
  • Deluxe — 43.6 lbs per case, woven top with non-woven bottom and 50/50 cotton/poly batting. The heaviest pad we stock.
  • Camouflage — 30.5 lbs per case, cotton/poly faces with linear poly batting.

Case weight is the honest indicator here: a heavier case means more batting per blanket, which is the only thing standing between a desk corner and a doorframe.

Office, Records and Commercial Relocations

A commercial move is a different problem from a household one. The volume is predictable, the contents are mostly paper and equipment, and the real risk is not breakage — it is not being able to find a file on Monday morning.

  • Standardise on two carton sizes so stacks are square and truck loading is efficient
  • Use file storage boxes for active records so they go straight onto a shelf at the other end instead of being unpacked twice
  • Number cartons by department and destination room, and keep the list off the boxes
  • Wrap desks, cabinets and monitors in blankets rather than boxing them
  • Take deliveries in phases so each department gets cartons the week it packs

We supply the cartons and the shelving they land on, which is usually where an office move goes wrong — boxes arrive before there is anywhere to put them. If records are staying boxed long term, look at records storage shelving or high-density mobile shelving before you rent more square footage.

How Many Boxes Do You Actually Need?

Count in cubic feet, not in boxes. Estimate the volume you are moving, divide by the cube of the sizes you plan to use, and add a margin — running out of cartons mid-pack costs more in time than an extra bundle costs in money.

1

1. Measure the volume

Walk the space and estimate the cubic feet of contents by area: closets, kitchen, records room, workstations. Volume, not floor area, is what fills a truck.

2

2. Pick two or three sizes

Dense material into 12 x 12 x 10″ and 16 x 12 x 12″; general contents into 18 x 18 x 16″; bulky and light into 18 x 18 x 24″ and 24 x 18 x 24″.

3

3. Divide by the cube

0.83 / 1.33 / 3.00 / 4.50 / 6.00 cu ft respectively. Dish pack is a rated 5.2 cu ft; the 20 x 20 x 45″ wardrobe is 10.4 and the 24 x 22 x 60″ is 18.3.

4

4. Round up to bundles

Bundles are 25, 20, 15, 10 or 5 depending on size. Order whole bundles of two or three sizes rather than a mixed handful.

5

5. Add the specialty cartons

One wardrobe per two to three feet of hanging rail, one dish pack plus partition kit per kitchen cupboard of china, one mirror carton per framed piece.

Or just send us the list

Tell us the size of the space, the number of workstations or the hanging-rail footage and we will build the carton list for you — including the bundle counts, the supplies to go with them and a delivery schedule. That service costs nothing and it is faster than an online calculator that has never seen your building.

Moving Box FAQs

What size moving box should I use for books and files?
Small cartons. Paper is the heaviest thing most people pack, so a 12 x 12 x 10″ box (0.83 cu ft) or a 16 x 12 x 12″ box (1.33 cu ft) fills up and still lifts safely. A 16 x 12 x 12″ packed solid with books lands in the 35-45 lb range; the same books in an 18 x 18 x 24″ carton would be over 100 lbs and the bottom would fail. For office records, deluxe file storage boxes are the better answer because they take letter or legal folders upright and stack on a shelf afterward.
What does ECT-32 mean, and when do I need double wall?
ECT is Edge Crush Test — the board’s resistance to crushing under a stacking load. ECT-32 single wall is the standard grade for general moving and shipping cartons and covers most of what people pack. Double wall board (ECT-48 on our wardrobe boxes, 51-ECT on the dish pack) has two fluted layers instead of one and is used where the carton is tall, carries a heavy or awkward load, or gets stacked several high — which is exactly the case for wardrobes and kitchenware.
How many boxes will a move actually take?
Work in cubic feet rather than guessing at box counts. Estimate the volume of what you are moving, then divide by the cube of the boxes you plan to use: 12 x 12 x 10″ = 0.83 cu ft, 16 x 12 x 12″ = 1.33, 18 x 18 x 16″ = 3.0, 18 x 18 x 24″ = 4.5, 24 x 18 x 24″ = 6.0, and the dish pack holds a manufacturer-rated 5.2 cu ft. Because our boxes come in bundles (10 to 25 depending on size), it is usually cheapest to order a bundle each of two or three sizes rather than a single size.
Do you sell moving boxes in single units or only in bundles?
Corrugated cartons are sold by the bundle, and the bundle quantity is set by the size — 25 for the small cubes, 20 for 18 x 18 x 16″, 15 for 18 x 18 x 24″, 10 for 24 x 18 x 24″, 5 for wardrobes and dish packs. Blankets and file storage boxes are sold by the case. If you need pallet or bale quantities for a large relocation or a retail programme, call us — most sizes bale at 120 to 500 and we quote those separately.
Can I hang clothes straight from the closet into a wardrobe box?
Yes, that is the point of them. Our wardrobe cartons are double wall ECT-48 with a write-on panel and hinged hand holes, in 20 x 20 x 45″, 24 x 20 x 46″ and 24 x 22 x 60″ for full-length garments. Add a steel hanger bar (20″ or 24″, rated 150 lbs) and clothes go in on their hangers and come out ready to hang. For folded clothing or off-season storage, the 36 x 21 x 10″ flat wardrobe box is cheaper and stacks better.
How should dishes and glassware be packed?
Use the 18 x 18 x 28″ dish pack — 51-ECT double wall, 5.2 cu ft, hinged hand holes, pre-printed fragile warnings — with the partition kit, which drops in three interlocking cell sets and two layer pads. Plates go in on edge, not flat, one per cell, each wrapped in newsprint. Fill every void: a cell that rattles is a broken plate. Glasses and stemware go in the upper cells.
What is the right way to pack framed art, mirrors and TVs?
Flat, edge-protected, and never lying down. The two-piece mirror box system telescopes: the inner box slides into the outer box, which is printed “Fragile Glass — Do Not Lay Flat”. For pieces that do not fit a standard size, four-piece mirror panels build a carton around any dimension between 30 x 40″ and 40 x 60″. Tape the glass face in an X with painter’s tape first so a break stays contained, then pad the corners.
What do you use for items that are too tall for a standard carton?
Telescoping boxes. An inner box slides inside a slightly larger outer box so the finished length is adjustable — lamps, floor mirrors, rolled rugs, curtain rods, artwork, banner stands. We stock inner/outer pairs from 10 x 6 x 57″ up to 12 x 12 x 48″ and beyond. Order the inner and outer boxes together; they are sold separately.
Can we get boxes delivered to a jobsite or a phased office move?
Yes. Stock ships from regional warehouses, and for a phased relocation we can split deliveries so each floor or department gets its boxes the week it packs, instead of storing a pallet of empty cartons in a hallway for a month. Tell us the schedule and the department count and we will build the release schedule into the order.
Can I reuse cartons from a previous move?
For light, non-fragile contents, yes — but check the flaps and the bottom seams, because board loses a meaningful share of its stacking strength once it has been loaded, taped and opened. Never reuse a carton for dishes, glass or anything you would not want to repack, and do not stack reused cartons more than two or three high. Old cartons flatten and recycle cleanly when they are done.
