Which is bigger, the Milky Way or the constellation?

Galaxies are celestial systems, and the sizes of different galaxies vary greatly. For example, the radius of earth-moon system is only 38,4401km, while the radius of the Milky Way is 50,000 light years. Galaxy has actual size and apparent size (apparent size, expressed by apparent radius), and the apparent radius of galaxy is related to line radius and distance. Constellation is just an artificially divided area of the earth's sky for the convenience of observation. Constellations are just a collection of certain directions seen from the earth. Just look at the size, not the actual size. Galaxies like the Milky Way, even the nearest galaxy, only occupy a small part of the earth's sky, which is much smaller than the sky of a constellation, because the actual distance is particularly far, and the directions of different places on the earth are not very different. You raise your head and put a leaf in front of you. This leaf can occupy a large sky and many constellations! You ask such a question because you don't know the meaning of the constellation.
