how to calculate glass

a lot depends on the glass (company) you are using. for machine made production glass, such as Spectrum, Armstrong, and the like, there is not variances in the sheets and colors, so a lot of extra footage is not necessary. Using hand mades (swirls and mottles), such as bullseye, uroborus, yogo, IMHO, you should actually handle the sheets, see what you want in them and then BUY about 3x what you think you need........gives you a lot of choices. Even with a "window", a large light box helps you to see the shadings, changes, and subtleties and gives you an idea of what the finished project will look like........if the window is a lot larger, you can view the project in sections BEFORE final soldering!

Up until about a year ago, one could NOT have too much glass, now the bidders on EBAY are benefiting from my hoarding of over 2 tons of glass, mostly handmade and custom sheets. ( plug for my auction) enjoy

My ballpark is double the square footage of the entire window if the pieces are moderate in size. But I NEVER make mistakes, and my cutting is perfect.

If I'm not mistaken, Armstrong and even Kokomo are all made just like Bullseye and Uro. A ladle of glass is poured on the table, mixed and the sheet is pushed into the mechanized rollers...one sheet at a time. Spectrum is the only one that makes a continuous ribbon of glass and is not hand ladled.
