Why would a supergiant have a brighter absolute magintude than a white dwarf?
A supergiant is much larger than a white dwarf. A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.
How much smaller is a white dwarf compared to its main sequence size?
A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
How do you define a white dwarf?
A white dwarf is a small luminous sphere about the size of the earth which is the final stage after the death of a star about the mass of the Sun.
What star is the same size as the earth?
A white dwarf can be roughly the same size as Earth.
Is a white dwarf star about the size of a city?
No, a typical white dwarf star is roughly the size of the Earth.
What is the size of a white dwarf compared to?
A white dwarf has the approximate diameter of a moon, or a small planet.

How large is a black dwarf?
The same size as the white dwarf it was. See related question.
How does the the mass and size of a white dwarf compare with the mass and size of the sun?
A white dwarf, also called a degenerate dwarf, is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth.
Is the Sun a white dwarf before becoming its present size?
No. In about 7.5 billion years the Sun will become a white dwarf.
How much smaller is a white dwarf compared to its main sequence size?
A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.

A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
