Footprint = 7-1/4 long - 32 sq in coverage
I have installed these shingles on an n scale church and they were a perfect fit. Very detailed and you need good eyes and lots of light to make sure you line them up correctly. I was impressed with how they looked when properly aligned. I would suggest that when you cut them to length, that you cut them about a 1/16 of an inch long, it makes them much easier to offset than trying to cut them exactly to size and then get them lined up correctly. I used a very thin layer of Elmer's glue and once the shingles were completely dry, trimmed the edges with a sharp Xacto knife. I am very impressed with how they look.
