What Size Telescoping Box Do I Need?

Key Takeaways

  • You need a base sized to your contents and a lid sized to the outside of that base. Two numbers, not one, and they are separated by the board thickness on each wall plus a working clearance.
  • If the box ships on its own or gets stacked, choose a full telescope where the lid covers the whole base depth, because that gives you a double wall on every side.
  • If the box is a gift piece that travels inside an outer carton, a partial lid covering a band of the base is usually enough and uses less board.
  • Minimum order is 100 complete sets of lid and base, from about $0.48 per unit at bulk volumes, confirmed on your written quote. The die for both pieces is included.

The short answer: there is no standard telescoping box size, and the size you need depends less on your product than on what the lid has to do. Below are the four situations buyers usually arrive with, and the answer for each.

Scenario 1: a gift box that ships inside an outer carton

Size the base snugly to the product plus its insert, and use a partial lid covering a band at the top. The outer carton is handling the transit stress, so the telescoping box is doing presentation work only. You will use less board and the base graphics stay visible. Keep the lid clearance small so the lid lifts slowly, which is most of the perceived quality in this format.

Scenario 2: a box that ships on its own

Go full telescope. When the lid covers the whole base depth, every wall is effectively doubled, and that is what stops a two piece box collapsing in a parcel network. Corrugated flute caliper is the reference here: E flute at about 1/16 inch keeps graphics clean, B at about 1/8 inch resists crush better, C at about 3/16 inch is the general shipping grade. Expect to be asked for the gross weight of the packed box, because that is what drives the board recommendation.

Scenario 3: one box, several product sizes

Telescoping construction is unusually good at this, because the lid can sit at different depths on the same base. If your products vary in height but share a footprint, one base plus one lid can cover the range, with the lid riding higher on the taller items. It does mean the graphics have to tolerate a variable overlap, so design the lid artwork so nothing critical sits at the bottom edge.

Scenario 4: heavy or dense contents

Size the base to the contents as normal, then ask about board grade rather than about size. A dense product in a small telescoping box puts all its weight on the base floor and the bottom corners. Double wall corrugated, meaning two fluted layers between three liners, or a rigid base with a reinforced bottom, are the usual answers. Tell us the packed weight on the quote request.

Getting the lid clearance right

Whichever scenario you are in, the lid is sized to the base exterior, never to the product. Take the base internal dimension, add the board thickness twice for the two walls, then add a working clearance so the lid slides. On rigid construction, chipboard is typically specified in the 1.5 to 3 mm range, so two walls is a visible difference. Label every number internal or external when you send it.

Cost and timing

The die for both pieces is included, along with plates, design support, US shipping and a digital proof before anything prints, so a base cut to your exact product costs no more to tool than a near standard one. Pricing starts from about $0.48 per unit at bulk volumes and is confirmed on your written quote. Turnaround is quoted per product in three lanes: rush (expedited production plus air freight, at a premium of about 7 to 25% depending on the job), standard by air and cost saver by sea, from about 7 business days plus 2 to 5 days for delivery. Specialty imported items can run up to about 12 weeks.

If you know which scenario you are in, send the product dimensions and we will size both pieces for you at /quote/. For the measuring method in full, read how to size a telescoping box, and order the format at two piece boxes.
