Paper Reel Weight Calculator
Use conditioned paper grammage matching the supplied paper and coating scope. Net paper excludes core and wrapping. Moisture state and tolerances can affect real mass.

First time using this calculator?
Replace the example values with figures from your supplier sheet or measurements. Choose the unit beside each value. Results update as you type; fix any highlighted field before using the result.
GSM means grams per square metre. Net weight excludes the core and other packaging. MOQ means the minimum order quantity. An optional field can stay blank unless the result you need depends on it.
Prices keep the selected currency; changing its label does not convert an exchange rate. Save or export the result after checking your inputs.
Help with paper web width
Measure the full width of the flat material from edge to edge, rather than the width of one finished pack. Choose the matching unit.
Help with conditioned paper grammage
GSM is the weight of one square metre of material, in grams. Find it on the supplier specification; use the complete laminate value for layered film.
Net paper mass
Net kg = Width(m) × Length(m) × Grammage/1,000
width = 1000; length = 1000; gsm = 120 → Net paper mass = 120 kgSaved calculations stay in this browser. No account or cloud backup is created.

Vary one input and inspect net paper mass
All other entered inputs stay fixed. Ranges are your scenarios, not statistical confidence or supplier performance predictions. This uses the same validated calculator engine.
The formula, made clear.
Use conditioned paper grammage matching the supplied paper and coating scope. Net paper excludes core and wrapping. Moisture state and tolerances can affect real mass.
How to use this calculator
- 01
Confirm paper web width, measured paper length, conditioned paper grammage.
- 02
Enter consistent units; zero means a confirmed absence of a charge or allowance.
- 03
Review the arithmetic, rounding and limitations before using the result in a purchasing decision.
A calculation you can check
A 1 m × 1,000 m reel at 120 GSM contains 120 kg of conditioned paper.
- Paper web width
- 1000 mm
- Measured paper length
- 1000 m
- Conditioned paper grammage
- 120 g/m²
width = 1000; length = 1000; gsm = 120 → Net paper mass = 120 kgCheck 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.
