Capacitance is measured in farads, which is defined so that a 1 farad capacitor has plusminus 1 Coulomb of charge on its plates when a potential difference of 1 Volts exists between them. In practice, typical capacitors are about a centimeter square and have capacitances of a few microfarads. If you wanted a 1 farad capacitor, about how big would if have to be? Don't just give a number, compare it to some familiar physical object.
