How many projects are enough for a portfolio?

Question

Summary

Now my portfolio site hosts 47 of my personal projects (39 educational and 8 commercial), and I really like all of them (in terms of quality). In terms of scale, they are all approximately the same, small projects, of course, I do not add to the portfolio.
It seems to me that there are too many projects. There are an order of magnitude fewer projects in the portfolio of my colleagues. Should I shorten my portfolio, or the more the better?

Answer 1

47 projects is just a number, we do not know what is there and how.
If you really like all your work in terms of quality, then most likely you are doing something wrong)
because. with each new work you learn something new, you find a different approach, etc., and you already understand how you can redo your past work.
What area is your portfolio in?

Answer 2

of course a lot, you need 42. Remove five pieces.
