FAQs

What does the paper weight calculator assume?

Calculate basis weight from measured stack mass, sheet count, and sheet dimensions. Every quantity that affects the result is entered explicitly; no regional chart, product preset, or vehicle-specific default is selected.

Use Cases

Verify paper weight for printing projects

Ensure your paper meets specifications for brochures, flyers, or business cards by calculating its g/m² basis weight.

Example: Check if a 500-sheet stack of A4 paper weighs 2.5 kg to confirm 80 g/m².

Compare paper types for crafting

Determine the weight of cardstock or specialty paper to choose the right material for your craft projects.

Example: Calculate the g/m² of a 100-sheet pack of 12x12 inch scrapbook paper.

Frequently Asked Questions

How do I use the Paper Weight Calculator?
Enter the total mass of your paper stack, the number of sheets, and the length and width of one sheet in your preferred units. The calculator will compute the basis weight in grams per square metre (g/m²).
What is basis weight in g/m²?
Basis weight is the weight of one square metre of paper, expressed in grams per square metre (g/m²). It is a standard measure of paper density and thickness, commonly used worldwide.
Can I use this calculator for any paper size?
Yes, as long as you know the total mass, number of sheets, and the dimensions of a single sheet. The calculator works for any rectangular paper size, including A4, Letter, or custom sizes.

Tips & Common Mistakes

Tips

  • Use a precise scale and measure dimensions accurately for the most reliable basis weight result.
  • If you have a single sheet, set the count to 1 and enter its mass and dimensions directly.
  • Ensure all measurements are in the same unit system (e.g., all metric or all imperial) to avoid conversion errors.
  • For stacks, weigh the entire stack including any packaging, then subtract the packaging weight if possible.

Common Mistakes to Avoid

  • Forgetting to convert units (e.g., mixing inches with centimeters) before entering values.
  • Using the weight of a ream (500 sheets) but entering the count as 1, leading to an incorrect g/m².
  • Measuring the dimensions of the stack instead of a single sheet, which overestimates the area.
