Wikipedia has a nice size analogy: https://en.wikipedia.org/wiki/Andromeda%E2%80%93Milky_Way_co...

Intuitively this visualization actually makes it seem like stars are pretty close? Usually with galactic dimensions it’s hard for our mere monkey minds to grasp the scales but this is actually pretty easy to imagine.
That's because you're significantly larger than the pingpong ball.
We really can't grasp just how large the sun is either; the earth would be a grain of sand in that scale. To me that still feels pretty vast
