A solar radii is used to express the comparison from one star to our own Sun.
If a star has a radius of 10.3 solar radii, then it has a radius 10.3 times larger than the Sun
Sirius BSirius B has a radii of 0.0084 solar radii.Barnard's star has a radii of 0.196 solar radii.

A solar radii is a unit of measurement used to describe the size or distance of an object relative to the Sun. It is often used in astronomy to compare the size of stars or planets to that of the Sun. One solar radii is equal to the radius of the Sun.
1180 solar radius
Typically,giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun.Whereas Supergiants have a radii between 30 and 1,000 solar radii and luminosities between 30,000 and 100,000 times that of the Sun
Antares has a radius (not raduis) equivalent to approximately 883 solar radii.
The largest star discovered so far is the UY Scuti red supergiant. It is approximately 1,708 solar radii, where one solar radii equals the radius of the Sun in our solar system.
The typical size of a white dwarf is about the size of Earth, which is approximately 0.008 solar radii. White dwarfs are very dense objects that have collapsed from the remnants of low to medium mass stars.
The largest star in Orion is Betelgeuse with a solar radii of 1,180.
Rigel has a radius of about 78 solar radii or 0.363 AU.
The largest known star now is UY Scuti with a diameter 2,375,828,000 km. UY Scuti has the radius of 1,516-1,900 solar radii, with the median radius of 1,708 solar radii, or approximately 7.94 astronomical Units.
As far as mass goes, R136a1 beats out VY Canis Majoris by 253 solar masses (265 solar masses for R136a1 vs Canis Majoris' 30). However, VY Canis Majoris beats out R136a1 in radius by about 1,385 solar radii (Canis Majoris is 1,420 solar radii vs R136a1's ~35).
