Generally, standard kitchen sinks are about 55.88 cm (22 inches) long to 76.2 to 83.8 cm (30 to 33 in) wide. On the other hand, single-bowl sinks measure up to 76.2 cm (30 in) in length. However, it’s still crucial to take proper measurements to avoid buying a sink with the incorrect size. If you’re replacing a drop-in sink with rims, start measuring from the outer lip of the sink instead of the basin itself.
