If the Milky Way galaxy were scaled down to the size of a postage stamp, what would the Local Group approximate in size?

About the size of a dinner plate

To visualize the hierarchical nature of cosmic geography, scaling comparisons are often utilized. When the Milky Way, which is about 100,000 light-years across, is reduced to the size of a postage stamp, the Local Group—a collection of about 50 galaxies spanning approximately 10 million light-years—is scaled up accordingly. In this comparative model, the Local Group would be equivalent in size to a dinner plate. This relationship illustrates that while the Local Group is significantly larger than a single galaxy, it remains a relatively small component when viewed in context with the larger structure, such as the Virgo Supercluster or the even more expansive Laniakea Supercluster.
