The short answer: for most retail folding cartons, somewhere between 16pt and 18pt. The longer answer is that thickness is chosen from three things, the weight of what goes inside, the size of the largest panel, and whether the box has to survive shipping on its own.
What a point actually measures
One point is one thousandth of an inch. So 14pt board is 0.014 inches thick and 24pt is 0.024 inches. It is a caliper measurement, not a weight, which is why two boards of the same point value can feel different if their densities differ. When you compare quotes, compare caliper and board type together.
A working guide by use
| Caliper | Typically suits | Watch out for |
|---|---|---|
| 12pt to 14pt | Small, light cartons: cosmetics samples, tea, small confectionery | Large panels will bow and dent easily |
| 16pt to 18pt | The general purpose retail range for most folding cartons | Very heavy contents still need a stronger base structure |
| 20pt to 24pt | Larger cartons, heavier contents, boxes that get handled repeatedly | Heavier board costs more and adds shipping weight |
Panel size matters more than people expect. A 12pt board is fine on a small carton and feels flimsy on a large one, because a bigger unsupported panel flexes more at the same caliper.
Three questions that settle it
- How heavy is the product? Glass, liquids and dense items push you up the range or into a glued auto bottom structure rather than a tuck base.
- How big is the largest flat panel? Big panels need stiffness, and stiffness comes from caliper or from structure.
- Does it ship alone? A carton posted on its own is doing a job paperboard was not designed for.
When paperboard is the wrong material
If the box ships by parcel without an outer carton, move to corrugated. E flute is roughly a sixteenth of an inch thick and prints finely enough for retail-facing work, which makes it the usual step up from heavy paperboard. If the box has to feel substantial and hold a crisp edge for presentation, that is rigid chipboard, commonly about 1 mm to 3 mm, wrapped in printed paper. Comparison is on rigid versus folding carton and rigid chipboard boxes.
Finish changes perceived thickness
Lamination adds a small amount of caliper and a large amount of perceived quality. A matte-laminated 16pt carton often feels more substantial than an uncoated 18pt one. If the goal is hand feel rather than protection, the cheaper route is usually finish, not board.
Getting it specified rather than guessed
Send the product weight, the intended carton dimensions and how the box travels, and the caliper will be named on your written quote rather than left to you. Design support is included. The minimum is 100 boxes per size and artwork, and bulk pricing starts from about $0.48 per unit. Turnaround is stated per product across rush (expedited production plus air freight), standard (air) and cost saver (sea), from about 7 business days of production plus 2 to 5 days for delivery, with specialty imported items up to about 12 weeks.
Send your specification to the quote form and ask for two calipers to be quoted side by side. If the box will be posted on its own, start instead at custom mailer boxes.
