We absolutely love this art! I bought the 27H X 18W. Spaced them 10 inches apart in between and they are 3 inches in from the edge of the headboard and sit 8 inches above the headboard. The bed is also from Wayfair, although I don’t care for the name of it , it’s the Romney Antique Gray King. Love the bed too and just ordered the matching nightstands. Way to go Wayfair!!
