**Three teaspoons or 1 tablespoon of ground coffee makes a 6-ounce cup of regular-strength coffee, according to Folgers.** The amount of grounds is doubled for strong coffee, while the amount of water stays the same.

A typical coffee scoop measures 2 tablespoons of coffee grounds, so one scoop is sufficient to make two 6-ounce cups. The amount of coffee required for a cup is the same for ground coffee and for whole-bean coffee that is ground just before brewing. Coffee made from instant crystals requires less coffee. One rounded teaspoon of instant crystals is enough to make a 6-ounce cup of regular-strength coffee.
