smaller stars will fuse typically up until carbon. at that point the star will eject material as it becomes less and less stable and the gravity can no longer hold on to the mass. eventually all that is left is a white dwarf. no more gasses, just a hot dense center slowly cooling down. this will be our star one day. these are roughly much smaller than our sun and are roughly the same size as earth.
compare the size of a small main sequence star to its white dwarf final form.

Explanation:

A small main - sequence star fuses up to carbon. Then, due to instability and gravity, it ejects material and becomes a white dwarf. A white dwarf is much smaller than its original main - sequence star form. For example, our Sun's white - dwarf form will be about the size of Earth while the Sun is much larger.

Answer:

A small main sequence star is much larger than its white dwarf final form.
