Stained Glass Calculators

Free online stained glass calculators.
Calculate glass area, lead came length, solder quantity, and material costs for stained glass projects.

Glass area, foil and came lengths, solder quantity and waste factors. 9 calculators for copper foil and leaded work. Kiln and hot glass work sits under Glass Blowing.

Cutting waste is where beginners underbuy, and the page is careful about a definition most published figures get wrong. Every percentage is added on top of the pattern area, so a 40% factor means buying 1.4 times the glass the finished panel contains. That is not the same as saying 40% of the sheet gets thrown away, which would be 29%. Mix the two up and you are short. Straight geometric work adds 10 to 15%, heavily curved Tiffany pieces 35 to 50%, and lampshade panels can reach 70%.

Copper foil totals piece perimeters rather than area, which is why a panel of many small pieces eats far more foil than one of few large pieces at the same overall size. Allow a quarter to half an inch per piece for the overlap.

A 4 inch circle has to come out of a 4 inch square. 21% of that square ends up in the bin, and no amount of careful scoring changes it.
