Rules for determining size of British WW2 upper wing roundels

[Seahawk]

Could someone please help me with the rules governing the size of British WW2 upper surface roundels?  I've already discovered that they are centred at 1/3 span from the centreline (so 1/6 span from the tip for aircraft not given to losing their wingtips) but I seem to recall something about space from the leading edge and from control surfaces (2" rings a faint bell).  Can anyone put me straight?  It's for a Kingcobra as used by RAE: definitely not a standard type!

 

Thanks in advance.

Standard sizing was the wing chord between the leading edge of the wing and leading edge of the aileron less 2 inches at 1/6 wing span from the wing tip. The two inches to be 1 inch from the wing leading edge and 1 inch from the aileron leading edge

Of course there were a great many which differed to this.

Hmmm.  Must be a cricket term! 😉
