I recall someone from a different group made a spreadsheet with the different presser foot dimensions for each maker which I contributed to and thought was a fantastic idea. Unfortunately it was on photo sharing site that got bought out and viewing was no longer free. There might have been 4 or 5 differnt dimensions including slot width, offset width if any, height, and a few others.
