Telescope box: blank size calculator and dieline
Two pieces: a tray-shaped base and a tray-shaped lid that slides over it, like a shoebox. The lid is a little larger inside than the base is outside. The generator puts both pieces next to each other on one sheet and sets the lid depth with a setting.
Blank size calculator
Why there is no formula here
There is no single formula for this page. The lid is sized from the outside of the base, with play for the fit, and the corner tabs are capped so they never reach past the middle of the wall. That cap makes the blank size jump at certain sizes instead of following one formula.
The calculator above runs the generator itself and gives the size of both pieces together.
Per board
The same 300 × 200 × 100 mm inside on each board. Thicker board means a bigger blank for the same inside size.
| Board | t (mm) | Blank (mm) |
|---|---|---|
| F-flute | 0.8 | 907.8 × 401.6 |
| E-flute | 1.5 | 912.5 × 403 |
| B-flute | 3 | 923 × 406 |
| C-flute | 4 | 930 × 408 |
| EB double wall | 4.5 | 933.5 × 409 |
| BC double wall | 7 | 951 × 414 |

- A regular slotted box is one piece with flaps; a telescope box is two trays.
Questions
- How much bigger is the lid of a telescope box?
- The lid's inside is the base's outside plus a small fit clearance, so it slides on without falling off. The generator works this out from the board you pick.
- Can the lid go all the way down?
- Yes. Set the lid depth close to the base height and you get a box with double walls all round. In the catalogue that is the telescope box with deep lid.
