The inscription on Sö 226 consists of runic text in the younger futhark that is carved on a serpent that circles along the outline of the stone, which is about 1.8 meters in height.
The runic text states that the stone was raised by four men named Bjôrn, Vébjôrn, Hrafni, and Ketilbjôrn in memory of their father Geirbjôrn.
