How can i private my profile picture in Facebook?

You can't, your profile picture is what shows people who you are. If you really want it private, delete the photo.

The other Luis is right; I just want to add that, well, nothing is really private on Facebook.

Your data is what fuels their business after all.

# at first click your profile picture
then click at the shown icon in pic.1.
then choose the option "only me"(if you want no one without you,can see it in full size ) or choose "friends"(only friends can see the enlarged pic.).
"custom"->you can choose among friends who can see it in full size.
thank you.

Mark your settings to private

You can't do this, because it is a Facebook internal feature so you can't modify it.
