It can have many different sizes. Only the largest giants are no longer main sequence stars.
Understand that the Main Sequence is not a place or a category that a star belongs to all its life. A star's destiny is controlled by its size and this determines how much time it spends on the Main Sequence.
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.
If Our Star Were the size of a Basketball, Sirius A (Main Sequence) Would be a size of A Teddy Bear.

A main sequence star is NOT a TYPE of star but a period in a stars evolution. Therefore all stars from the hottest to the coolest are on the main sequence at some stage - with the exception of brown dwarfs which do not reach the main sequence.
Approximately 90% of stars in the universe are categorized as main sequence stars. These stars, like our Sun, are in the stable phase of their lifecycle where they fuse hydrogen into helium in their cores. Main sequence stars vary in size and temperature, leading to differences in brightness and color.
The term "main sequence" refers to stars that are in the phase of their life cycle where they are fusing hydrogen into helium in their cores. It is called the main sequence because the majority of a star's life is spent in this phase, during which it maintains a stable energy output and size.
The four types of stars are; Main Sequence, White Swarfs, Red Giants and Super Giants. 90% of stars are in the Main Sequence.
Main sequence stars do not really exist - well they do, but read on. Main sequence is a stage in a stars life - where it converts hydrogen into energy, not a particular star or type of star. All stars go through a main sequence, from the smallest to the largest.However, in general, the larger the star, the faster it will burn off it's fuel.
Main sequence stars best obey the mass-luminosity relation. This empirical relation states that there is a direct relationship between a star's mass and its luminosity. In general, the more massive a main sequence star is, the more luminous it will be.
