Wire guage needed for standard stove/oven combo
A "standard" cooktop only, or a single wall oven, will typically be on a 30A-120/240V circuit, requiring 10/3 cable.
Keep in mind, I have seen many newer cooktop models that require a 40A circuit. It all depends on the kW rating.

A free-standing range, rated 12kW or less, can typically be wired to a 40A-120/240V circuit using 8/3cu or 6/3al cable.

A typical electric dryer, and most combined stackable units, will require a 30A-120/240V circuit using 10/3 cable.
