Sample Box Dimensions

Key Takeaways

  • Sample boxes are sized from the outside in: the mail class or parcel band you want to hit sets the maximum outside dimensions, and the contents are arranged to fit inside that.
  • Depth is the dimension that decides postage on small shipments, so a sample box is usually laid out flat and wide rather than tall.
  • Carriers bill the greater of actual weight and dimensional weight, which is why a lightweight sample in an oversized box can cost more to post than the sample cost to make.
  • iBox Factory does not sell a sample kit. Samples of packaging are arranged through the quote conversation, and custom sample boxes are made from a 100 box minimum.

Sample boxes are the one packaging format where you should design from the postage backwards. The contents are usually small and light, so almost the entire cost of a sampling programme is the shipping, and shipping is set by the outside dimensions of the box. Work in that order and the rest follows.

Start with the mail class, not the product

Decide which parcel band or mail class you want every sample shipment to fall into, then find the maximum outside dimensions that band allows, then design the interior to fit inside them. Carrier rules and thresholds change, so check the current specification with your carrier rather than working from a figure someone quoted you last year. Give us the maximum outside dimensions you need to stay under and we will build the box to land inside it.

Depth is the expensive dimension

On small shipments, thickness is usually what moves a parcel from one band to the next. Two practical consequences. First, lay contents out side by side rather than stacking them. Second, choose sample formats that are inherently flat: a sachet instead of a jar, a swatch instead of a folded piece, a card mounted vial instead of a loose one. If one item in the kit is thick, it sets the depth for the whole box, so it is worth asking whether that item needs to be in this shipment at all.

What each sample type needs

Miniature jarsDiameter plus lid rimA cut out well in a chipboard platform
Fabric or material swatchesStack thicknessA shallow tray, banded or tucked under a flap

Construction that suits sampling

Most sample boxes are one piece mailers, because they need no tape, close in one motion and open cleanly in front of a customer. If you send hundreds a week, the seconds saved per box at pack out matter as much as the unit price. Printing the inside of the box is worth considering here more than in almost any other format, since a sample box is opened by exactly the person you are trying to persuade. A fitted platform also stops the contents from becoming a jumble in transit: see custom insert packaging for the options.

Getting samples of your own packaging

A note, since people arrive on this page looking for both things. iBox Factory does not sell a sample kit and there is no sample pack to buy. If you want to see materials or a build before committing to a run, raise it in the quote conversation and we will tell you what is possible for your job.

Ordering sample boxes

Minimum 100 boxes per design. Pricing starts from about $0.48 per unit at bulk volumes, confirmed on your written quote, and the die, the plates, design support, US shipping and a digital proof before printing are included. Turnaround is stated per product across three lanes: rush is expedited production plus air freight, standard is air, and cost saver is sea, from about 7 business days plus 2 to 5 for delivery, with specialty imported items running up to about 12 weeks and rush adding about 7 to 25% depending on the job.

To check your outside dimensions against board thickness, use corrugated box dimensions. To have a sample box built to a postage limit, send that limit and your contents list through the quote form.
