Most sizing pages have to teach a method because no standard exists. Dice are the exception. The dice themselves come in well established sizes, and the set composition is conventional, so you can calculate an internal box dimension on paper before you ever touch a sample.
The standard inputs
| Input | Industry-typical figure |
|---|---|
| Common six-sided die | 16 mm across the faces |
| Casino style die | 19 mm, square edged |
| Miniature or travel die | 12 mm, sometimes smaller |
| Polyhedral role-playing set | Seven dice: d4, d6, d8, d10, percentile d10, d12, d20 |
These are industry-typical reference figures, not iBox stock sizes. Confirm the actual dice you have sourced, because novelty, resin and metal dice vary from the conventions above.
Calculating the internal footprint
- Decide the grid. A seven-piece polyhedral set is commonly laid out as a single row, a two by four tray with one blank cell, or a shaped foam cut to each die.
- Multiply the die size by the number of cells across, and again by the number of rows.
- Add the partition wall thickness between every cell, and once more at each outer wall.
- Set depth from the largest die in the set, usually the d20, then add the insert floor thickness.
Quote the total as internal length x width x depth, and write internal on the quote. On a small box the board caliper is a meaningful fraction of the total, so the inside and outside numbers diverge more than people expect.
Insert choices
Foam is the default for premium dice because it silences the rattle and holds each die in place when the box is tipped. Die cut board partitions cost less and ship flat, which matters if you are producing a high volume set at a lower price point. Velvet-lined rigid trays are the top of the range and change the box from packaging into part of the product. Metal and resin dice are heavy for their size, so a partition that would hold plastic dice may not hold theirs.
Structure and finish
Three formats dominate: a small rigid two piece lid and base for collector sets, a magnetic closure box for sets sold as gifts, and a printed tuck end carton for volume retail. Foil, soft touch lamination and spot gloss all work on a small footprint, and on a box this size the finish is a large share of what the customer perceives, because they are holding it close.
Ordering
Minimum order is 100 boxes, and pricing starts from about $0.48 per unit at bulk volumes, confirmed on your written quote. The die and plates, design support, US shipping and a digital proof before anything prints are included, so a tray cut around your own grid tools no differently from a near-standard one. Turnaround runs in three lanes, quoted per product: rush with expedited production and air freight, standard by air, and cost saver by sea, from about 7 business days, plus 2 to 5 for delivery. Specialty imported items can run up to about 12 weeks. Production is in West Chicago and Guangzhou.
For the retail box itself, game boxes is the page to order from, and if the dice ship alongside cards, the playing card box guide covers the deck side of the same pack. Send your die size, set count and preferred grid to request a quote.
