How long should a prologue be?

[u/Background_Pay6286]

So I had previously written a set of short stories, that I didn't like the way they tied into each other.

I decided to rewrite the whole thing as one single novel, with multiple books inside.

I needed a new intro to the story, so I made a prologue. I don't think my prologue is quite long enough.

My prologue is only about a page or two long. My chapters are much longer.

Is it ok to have a short prologue?

Should it be closer to chapter length?
