A black dwarf is any stellar remnant, that has cooled completely, so that no radiation is emitted.
They - at the moment - do not exist, as the Universe has not been around long enough for any stellar remnant to cool to this state.
A black dwarf would - if it existed - be anywhere from the size of a city (Neutron star) up to 1.4 times larger than the Earth.

A black dwarf is a hypothetical stellar remnant that forms when a white dwarf cools down over trillions of years. Its size would be similar to that of Earth, as it would have shrunk significantly in size from its original white dwarf stage.

Can a mid sized star become a or a black dwarf?
Yes, a mid-sized star can eventually become a white dwarf or a black dwarf. After exhausting its nuclear fuel, the star sheds its outer layers to form a planetary nebula, leaving behind a white dwarf. Over trillions of years, a white dwarf may cool and fade into a black dwarf, although this process would take longer than the current age of the universe.

What is smaller black hole or white dwarf planet?
Depends!!!A white dwarf created from a star the same size as our Sun will only be the size of our Earth.A supermassive black hole can have a diameter of 150 million kilometers (Same distance from the Earth to the Sun).However a stellar black hole can only be 30 kilometers in diameter.There is no minimum size for a black hole, so one "could" be as small as 0.1mm
