The medium plug is ~33mm at the bottom flaring out to ~36.5mm at the top.
The scupper hole sizes vary between kayaks. If the bung feels a bit loose or water pressure pushes it out of the hole, you can wrap some electrical tape around it to shim it out & make a good fit. If the bung is a bit too large, you can cut a 'V' shaped section into the side of it to allow it to better fit into the hole.
