GSM Calculator for Paper and Fabric

What is GSM? Definition & Units

GSM (Grams per Square Meter) is a standard measurement that indicates the weight and thickness of a material such as fabric, paper, or card over a one-square-meter area. A higher GSM value typically means a denser or heavier material.

Length and Width Units (used to calculate area):

• Millimeter (mm)
• Centimeter (cm)
• Meter (m)
• Inch (in)
• Feet

Weight Units (used to measure material weight):

• Gram (g)
• Kilogram (kg)

Why Do You Need a GSM Calculator?

An online GSM calculator helps you quickly and accurately determine the weight per square meter of materials like fabric, paper, or packaging. This is essential for quality control, cost estimation, product comparison, and selecting the right material for specific applications.

Instead of doing manual calculations or worrying about unit conversions, you can trust our GSM Calculator to get accurate and quick results. Just enter the weight and dimensions of the sample, and let the tool handle the rest. It saves time, reduces errors, and helps you make confident decisions every time.

Common Uses of GSM Values

• 60–90 GSM – Used for lightweight materials like copier paper and summer fabrics
• 100–170 GSM – Suitable for flyers, posters, shirts, and soft apparel
• 200–300 GSM – Common in high-quality cards, dresses, and curtains
• 300+ GSM – Ideal for packaging, invitation cards, denim, upholstery, and jackets

Note: There is no strict maximum value for GSM, as it depends on the type of material and its intended use.

GSM Formula

GSM (Grams per Square Meter) is calculated using a simple formula:

GSM = (Weight in grams × 10,000) ÷ (Length × Width in cm)

Here,

• Weight (Wg) is the sample’s weight in grams
• Length (L) and Width (W) are the sample’s dimensions in centimeters
• The number 10,000 is used to convert square centimeters into square meters, since 1 m² = 10,000 cm²

Manually converting units and calculating area can be time-consuming and error-prone. Our GSM Calculator automatically does this calculation for you. Just enter the values, select units, and get accurate GSM results instantly.
