The guide
Each step in the order you'll need it.
Boxed sneakers, electronics and heavy stock
Use double-wall boxes for boxed sneakers and electronics, or heavy home goods that must arrive without a dent. At 18 × 12 × 8 inches, this size takes a boxed pair of adult sneakers with room for padding around the shoebox.
A 15 pack covers a sneaker or electronics reseller shipping a few boxes a week. If you ship high volumes from a garage, buy by the bundle from a packaging supplier.
Flutes, flaps and inside size
Double-wall cardboard has two fluted layers, so the boxes stack higher and resist more edge pressure. Look in the listing for the flute combination, such as BC, and a strength rating such as 275 lb test or 48 ECT. The quoted size is usually inside dimensions and the outer box is a little larger, so use the outer size when you buy the label.
Full flaps top and bottom let you seal the box with an H-seal. Reject boxes that arrive creased or with crushed edges.
Measure your largest boxed pair of sneakers before you buy. Some high-top and large-size shoeboxes need a bigger box.
Packing boxed sneakers or electronics
Tape the base with an H-seal of packing tape. Lay a bed of bubble wrap or crumpled paper, then wrap the shoebox or product box in a layer of bubble wrap to keep its corners sharp.
Pack void fill into each gap until the inner box cannot shift. Close and seal the top, then put the label on the largest face, away from the seams.
Weigh and measure the packed box before you buy a label. Carriers charge by dimensional weight on larger boxes, so a light 18 × 12 × 8 box can cost more than its scale weight suggests.
Single-wall boxes or rigid mailers instead
Small single-wall boxes cost less per box and suit light items under a few pounds that only need a rigid shape.
Rigid mailers suit flat items and add less weight to the package. For high-value jewelry or bags, put a rigid presentation box inside a double-wall box, and keep the presentation box clear of tape and labels.
$3 to $4.70 a box against a refund
At $45 to $70 for 15, each box costs more than a single-wall box. On a $150 pair of sneakers, a refund for a crushed shoebox costs you the sale as well as the box.
If you sell boxed sneakers or collectibles, buyers judge condition by the box that comes with the item, so keep that box undamaged. Add the shipping box cost to your listing price.
Common mistakes
Each one costs you money or reviews, and each has a fix.
- Wrap the shoebox and fill the gaps, or the corners crush against the box walls.
- Don't tape a label onto the product's own box. Put boxed stock in an outer box and label that.
- The quoted size is usually inside dimensions, so the packed box can come out bigger than you priced for. Measure the packed box.
- Seal the bottom with an H pattern, or a heavy base can split open with only the top taped.
- Don't reuse a crushed box for heavy or fragile items, because it has lost strength.

Questions
Straight answers to what sellers ask about this.
Do 18 × 12 × 8 inch boxes fit boxed sneakers?
They fit most adult shoeboxes with room for padding. Measure larger sizes and high-top boxes before buying.
Is double-wall worth the cost over single-wall?
For heavy or fragile items, yes: one damage refund costs more than a box at $3 to $4.70.
Does dimensional weight apply to this box?
It can. USPS, UPS and FedEx each set when they charge by size instead of weight, so check their current rules or compare rates in your label tool.
Is the listed size inside or outside?
Most listings quote inside dimensions. The outer box measures a little more.
How much padding do I need inside?
Enough that the inner item cannot move when you shake the box. Leave room for padding on each side.
