The scale I used for the Soubasse pipes is from the Laukhuff catalog for a medium Bourdon. The scale halves on the 19th note. The basic pipe design is from the Audsley book. Here's a sketch showing a front and cross section view of a Soubasse pipe followed by a table of dimensions (inches) for the entire rank:
| T | Wall Thickness | PS | Pipe Size |
| CH | Cap Height | IW | Internal Width |
| BT | Bottom Thickness | ID | Internal Depth |
| WST | Windsheet Thickness | IL | Internal Length |
| MH | Mouth Height |
