Paper Sheet Weight Calculator
Paper grammage expresses mass per square metre. The calculator scales grammage by the physical area of each sheet and the number of sheets.
How to use this calculator
- Enter sheet width (mm), sheet height (mm), grammage (g/m²), number of sheets using the same measurement window and units.
- Check the result and intermediate values, then change one input at a time when comparing scenarios.
- Keep the stated scope and assumptions attached to any result you share.
Formula and method
Mass per sheet (g) = width (m) × height (m) × grammage (g/m²); total mass = per-sheet mass × sheet count.
- The estimated paper mass is about 2.494 kg before packaging and manufacturing variation.
- Actual sheet dimensions, moisture, coatings and stock tolerances affect weighed mass. Packaging is not included.
Worked examples
Worked example
500 A4 sheets at 80 g/m².
The estimated paper mass is about 2.494 kg before packaging and manufacturing variation.
The estimated paper mass is about 2.494 kg before packaging and manufacturing variation.
Understanding the result
The estimated paper mass is about 2.494 kg before packaging and manufacturing variation.
Actual sheet dimensions, moisture, coatings and stock tolerances affect weighed mass. Packaging is not included.
Important notes
Actual sheet dimensions, moisture, coatings and stock tolerances affect weighed mass. Packaging is not included.
Use measured inputs or documented assumptions, and validate important decisions with the appropriate source specifications or professional guidance.
Frequently asked questions
Is grammage the same as thickness?
No. Grammage is mass per area; thickness depends on paper composition and bulk.
Does this include wrappers or boxes?
No. Add packaging mass separately if estimating shipment weight.
