One of the flags that I plan to make will be an accurate as possible replica of the 15 star/15 stripe Star Spangled Banner. The Smithsonian states the original size was 30 feet by 42 feet. I wish to fab a flag about 36" on the fly side. My question is (because I am terrible at math) what would the length be, given this scale? Anyone care to please calculate this for me? My guess would be around 46"? The stars in the canton of the original measure 2 feet. Anyone willing to please calculate the size I would need to make these based on the ratio of the overall flag? Now, assuming that the canton is a true square, I will make the canton the same height and width as the 8 horizontal stripes. Thank you for your help in allowing me to make an accurate, scaled-down version of this historic flag!
