Work through the task
- Use the approved blank envelope or dieline convention required by the calculator. Flaps and glue tabs must not disappear from the input.
- Check complete blanks in each layout orientation and whether grain, print and machine constraints permit it. An area ratio is not an approved layout.
- Translate purchased board into the agreed finished-carton price scope and compare finishing, die-cut setup and order charges.
Tools for this job
Carton Blank Area Calculator
Calculate rectangular blank area from actual die-line envelope dimensions without inferring blanks from finished cartons.
Open calculator →Cartons per Sheet Calculator
Calculate carton blank counts in two rectangular sheet orientations and identify the higher simple layout yield.
Open calculator →Folding Carton Board Requirement Calculator
Plan gross paperboard area and weight for a carton order, with optional whole-sheet purchasing quantities.
Open calculator →Folding Carton Supplier Quote Comparison Calculator
Compare folding carton supplier prices, first-order and repeat-order landed cost, MOQ and specification differences.
Open calculator →A worked example
A 0.5 × 0.4 m blank envelope has 0.20 m² area. At 300 GSM it represents 60 g of board. Ten thousand envelopes represent 600 kg before layout and process losses; cutouts do not automatically reduce purchased sheet cost.
Use your supplier specification and quotation. These numbers demonstrate the arithmetic; they are not market prices or a packaging suitability assessment.
Checks before you decide
- Approved dieline and grain direction
- Purchased envelope versus retained mass
- Print, glue and finishing included in quote
