[MR] Banner regulations?

[Glynis Gwynedd]

I have been requested to find out if there are any guidelines or
restrictions on size, shape, and usage of banners in the Kingdom of
Atlantia?  I am told, and I'm fairly sure this is a mere rumor, that
Meridies may have adopted some sort of standards when it comes to
banners.

In other words, is there a standard size, or set measurements, for
banners displayed by, say, a Landed Baron, or by an armigerous person?
 Our Baron and his administrative assistant (his wife) wish to know.
