Diapers are almost always compressed and sealed in a polybag before they go into a box. That bag, not the diapers themselves, is what the box has to hold. The iBox custom diapers boxes page describes building corrugated subscription cartons from the diaper pack's actual compressed dimensions, so there is no void space and no shifting in transit.
What sets the size
- Size stage. Diapers get larger as the stage number goes up, so the same count makes a bigger pack.
- Count. Packs at different stages often carry different counts, which changes the pack size again.
- Compression. How tightly the pack is compressed affects its dimensions.
- Format. A retail carton, a bulk subscription carton and a sample sleeve each hold very different quantities.
How to measure a diaper pack
- Take sealed packs from a normal production run, not hand-made samples.
- Measure length, width and height of the bagged pack at its widest points. Bagged packs bulge in the middle.
- Measure several packs and use the largest reading, since packs vary a little.
- Repeat for every stage and count you plan to box.
Worked example (illustrative only)
If a sealed pack measures 12 x 8 x 6 inches at its widest, a box with about 0.25 inches of clearance on each side would start at roughly 12.5 x 8.5 x 6.5 inches inside. A subscription carton holding two packs side by side would double the width before clearance is added. These numbers only show the method; your packs set the real size.
One footprint or one box per stage?
A brand running five or six stages has a choice. Separate boxes per stage fit best and waste no space. A shared footprint with different depths keeps shelf facings uniform and simplifies storage, at the cost of some empty space on smaller stages. Whichever you choose, the product page recommends making the stage number and pack count the main display elements, with the baby weight range directly below, so parents can read them at arm's length.
Carton or corrugated
| Format | Material on the iBox page | Use |
|---|---|---|
| Retail carton | Coated paperboard, 350 to 500 gsm board | Shelf packs in baby care aisles |
| Subscription carton | Corrugated board | Bulk monthly deliveries that need strength for a full count |
| Sample sleeve or small carton | Sleeve box or small folding carton | Newborn kits and trial counts |
A full subscription count is heavy, so corner strength matters more than on a retail pack. The product page notes corrugated outers are chosen for enough board strength to handle the weight without corner failure.
Features that affect dimensions
The iBox page lists handle, tear strip and gloss lamination as add-ons. A carry handle cut into the top needs board above the pack and a little headroom so fingers do not press into it. A tear strip opening needs a clean panel with no artwork that has to stay readable after tearing. Back panels also need room for a barcode and lot code zone.
Ordering diaper boxes to size
Send the sealed pack dimensions for each stage and count, the format and your quantities. Custom sizes add nothing to tooling because the die and plates are free. The minimum is 100 boxes per design, design support and US shipping are free, and a digital proof comes before printing. Start on the quote form, browse related items on the custom baby product boxes page, or see shipping box dimensions for the outer carton.
