Tuck end box blank size calculator

Estimate the flat blank of a reverse tuck end carton and how many fit on a press sheet.

Units

How it works

A reverse tuck end (RTE) carton closes with a tuck flap at the top on one side and at the bottom on the other. The blank runs across four panels plus a narrow glue flap, and up through the height plus two closing panels and two tuck flaps.

Blank width ≈ 2L + 2W + glue   Blank height ≈ H + 2W + 2 tucks

Dust flaps sit within these limits, so they don't add to the blank. The sheet count assumes a 28 × 40 in (or 71 × 102 cm) press sheet and simple rows; printers often nest blanks to fit more. Need the carton size first? Use the folding carton size calculator.

Results are estimates based on typical industry values. Confirm final specifications with your supplier or carrier.

Frequently asked questions

What is the difference between reverse and straight tuck end?

Reverse tuck end closes at the front on top and at the back on the bottom. Straight tuck end closes both ends on the same side, which looks neater on a shelf but nests less efficiently on a sheet.

What paperboard thickness should a tuck box use?

Most retail cartons use 16 to 18 pt. Heavier products or premium packaging use 20 to 24 pt.
