There is no single crayon box size, because the box is a function of three variables you control: the crayon, the count and the layout. Do the arithmetic once with your own crayon and you will have a defensible internal dimension in a few minutes.
The layout arithmetic
Measure one crayon with the wrapper on, since the wrapper is part of the diameter. Then:
- Internal length = crayon length + about 1/8 in end clearance. This is the easy axis and it does not change with count.
- Internal width = crayons per row x crayon diameter, plus roughly 1 to 2 mm of total slack so a machine or a hand can load the row without forcing it.
- Internal depth = number of layers x crayon diameter, plus slack. One layer keeps the box flat and the crayons visible on opening. Two layers make a chunkier, more giftable box.
Worked through, a 24 count laid as a single row of 24 gives a very wide, awkward box. The same 24 count as two rows of 12 is compact and stable, and as three rows of 8 it becomes close to square. Try two or three layouts on paper before you commit, because the layout decides the shelf presence as much as the print does.
What holds the crayons still
| Option | How it works | Suits |
|---|---|---|
| Tight fit, no insert | The crayons fill the internal width so nothing moves | Single layer sets with a consistent crayon diameter |
| Corrugated or board partition | Cells or fences hold each crayon or each row apart | Larger counts, mixed diameters, and boxes that are reopened repeatedly |
| Moulded or die cut tray | Each crayon sits in its own recess | Gift and premium sets where the reveal matters |
| Flip top with a lid that stays attached | Keeps the lid with the box through repeated use | Children's sets that get opened hundreds of times |
Board, print and durability
A crayon box gets opened, closed, dropped and sat on. Board caliper is measured in points, one point being a thousandth of an inch, and going heavier here is money well spent because the failure mode is a torn tuck flap rather than a crushed panel. If the box needs to survive a classroom, consider a thicker board or a flip top construction that spreads the stress across a hinge instead of a tuck.
Print is usually the selling surface on this category, with strong colour and a panel showing the shade range. A digital proof comes before anything prints, so you can check that your printed colour swatches sit close to the actual crayons before the run starts.
Ordering and turnaround
Minimum order is 100 boxes per configuration. Pricing starts from about $0.48 per unit at bulk volumes and is confirmed on your written quote, because count, layout, insert and print coverage all move it. Die, plates, design support, US shipping and a digital proof are included, which is the reason a bespoke count layout carries no tooling penalty.
Turnaround is stated per product across three lanes: rush (expedited production plus air freight, a premium of about 7 to 25% depending on the job), standard by air, and cost saver by sea. The floor is from about 7 business days, plus 2 to 5 days for delivery. Specialty imported items can run up to about 12 weeks, which matters if you are planning to a back to school date. We produce in West Chicago, US, and Guangzhou, China.
Send your crayon length and diameter along with the count and the layout you want, and we will confirm the internal dimensions and the insert on a written quote at /quote/. To order the format itself, see custom crayon boxes.
