Hello,
The screen doors that are used for this design are no longer available, unfortunately. The manufacturer of these doors closed years ago and Imaginating was unable to find a replacement for the doors. Just by looking at the picture my best guess would be the doors are around 10" wide by 24" high but I am completely going off of the picture. There is no information provided on the leaflet as far as sizing for the door.
