WW1 US Victory Ribbon Battle/Campaign Star Regulations

[Mint]

Anyone know what the official size is for the bronze battle stars that were used on the WW1 US Victory Medal Ribbon?

I have attached photos for reference that I found online.

According to "The Call of Duty" book, the bronze and silver service stars were 3/16th of an inch.

The Gold and Silver stars used to denote a subsequent award for the Navy, Marines and Coast Guard were 5/16th's.

Thank you MAP! So the standard size for the stars has been the same since WW1?

I would assume so, but I'm no expert. The book does not distinguish between different era's for these.
