It's so close it isn't to be worried about. Yes 3/16" is a nice compromise between 1/4 and 1/8. 1/4 is good but is overkill. I feel 1/8 is a little weak once you start wrestling with a stuck print. Glass is glass, it will break if stressed too much.

You should be able to use a 1/4" spacer for 3/16". Just unscrew the levelers a little more.

My platform kit comes with spacer for glass and no glass.
