Cardstock

Paper weights and types can be very confusing. There are two basic systems in use: the U.S. system which sizes the weight in pounds, and the Metric system, which sizes the weight in grams / meter squared (g/m²), or more commonly referred to as grams per square meter (gsm).
Paper weights here in Australia are measured in grams per square meter (gsm). As a general rule, anything 10-35 gsm is of tissue consistency; 35-70 gsm is lighter textweight, 70-100 gsm is medium textweight, 100-120 gsm is heavy textweight/light cardstock, 120-150 gsm is regular cardstock weight, 150-200 gsm is heavy cardstock, and greater than 200 gsm is super heavy cardstock.
