What is the Packaging Material Calculator?
Before a big order or sale season, you need to know how much packaging to buy. The packaging material calculator totals the board, tape and void fill for a batch of boxes so you can order once and avoid running out.
For the cost of these materials per box use the Packaging Cost Calculator; for overall counts of boxes, pallets and labels see the Packaging Quantity Calculator. All calculators accept centimetres, inches or millimetres and kilograms or pounds, so you can use the units on your supplier's spec sheet.
How to use the Packaging Material Calculator
- Enter box dimensions and quantity.
- Enter board GSM and tape roll length.
- Enter the product volume to estimate void fill.
- Read totals for board, tape and fill.
Formula
Void fill = box volume − product volume · Tape per box (H-tape) ≈ 2L + 4W + 2H
Example
500 boxes of 30 × 20 × 15 cm need about 170 m² of board, around 1.5 km of tape (about 23 rolls of 66 m) and 4.5 m³ of void fill if the product takes half the box.
Reducing packaging waste
- Right-size boxes to reduce void fill.
- Use paper-based fill instead of plastic where possible.
- Choose the lightest board that passes your strength needs.
- Reuse inbound cartons for internal moves.
