The carvings of the rock face are in the runestone style Pr 5 (c. 1100-1130) pertaining to the late Urnes style.
Though the inscription is not signed, it is attributed to the runemaster Öpir for stylistic reasons.
The inscription is c. 1,60 m tall and 0,87 m wide.
The first part of the rune text begins at the tail end of the rune animal and ends at the top of the inscription. The second part begins at the head end of the rune animal and ends at the top of the inscription. The two parts share the same n-rune as the last letter in each of the two sentences.
