Laminate Yield Calculator
Build a laminate structure and calculate its theoretical square metres per kilogram. The result includes every layer and dry addition entered in the structure builder.
Build the structure, layer by layer.
Typical density. Actual density varies by resin grade and formulation; use supplier or measured data when available. Measured or supplier GSM is generally more reliable than a density-derived estimate. For custom materials, enter a verified density. Do not use a generic density to estimate paper GSM.
Adhesive, print & coatings
Enter zero for an excluded addition. All GSM inputs are dry, retained mass per square meter. Adhesive, ink and coating thickness is not inferred from their GSM.

| 1. PET / BOPET | 16.68 |
| 2. PE (generic) | 55.20 |
| Adhesive interface 1 | 2.00 |

Film thickness excludes adhesive, ink and coating thickness. Yield is theoretical, before process waste. This estimate includes typical library densities.

Layer GSM = thickness in µm × density in g/cm³.
Total GSM = sum of film-layer GSM + dry adhesive + ink + coatings + other retained mass.
Yield = 1,000 ÷ total GSM.
PET / BOPET: 12.00 × 1.39 = 16.68 g/m²
PE (generic): 60.00 × 0.92 = 55.20 g/m²
Total: 16.68 + 55.20 + 2.00 additions = 73.88 g/m²
Yield: 1,000 ÷ 73.88 = 13.54 m²/kg
The formula, made clear.
The calculator first sums the mass per square metre of the layers and retained additions. Dividing 1,000 grams by that complete basis weight gives area yield per kilogram. Adding adhesive or a heavier layer increases GSM and reduces yield. This makes yield useful when comparing a structure change: the same kilogram price may produce a different area price because each kilogram covers a different amount of web.
How to use this calculator
- 01
Build the laminate with the intended materials, thicknesses and editable densities.
- 02
Enter total retained dry adhesive, ink, coatings and other mass.
- 03
Read complete-film GSM and the resulting area yield before applying a material price.
A calculation you can check
The example derives area yield from the full mass of the entered laminate, including its specified dry additions.

Check the displayed formula and units against your quotation. Use measured GSM, net weight and actual layout dimensions where available. Default densities are planning assumptions, not certified material properties. Calculated cost does not certify strength, compatibility or safe loading.
