In the original image, the scale is 1 pixel = 2 inches. For comparison, the largest pipe in the organ (the bass CCC in the Bourdon 16 in the Pedal division) is 98.6″ tall. The smallest pipe in the organ (the g3 in the Nineteenth 1 1/3 in the Great division) is 0.5″ tall. The widest-scaled rank in the organ is Nacht Horn. The narrowest is the Violoncello (eventually it will be the Viola but I haven’t done the scaling work on the Choir division yet).
