National Insignia markings- size by plane type?

[Lanny109]

Greetings all, Hopefully this isn't too common a question to ask... I am after a list of the appropriate sizes for markings on a luftwaffe plane by plane type. The closest I've come to is an Airfix pic someone posted on a modeler's forum from that listed the 5 regulation sizes for German aircraft, along with a conversion chart. The problem is I can't find which size is appropriate for which plane. I've been 'guesstimating' sizes from period pics but have come up with very inaccurate results as reward for hours in photoshop. I have gone through about a dozen of the common 'planes of' type of book in hopes of figuring things out with no breakthroughs. Any help would be appreciated, Thanks!
