I am looking at these exact tiles for a backsplash. However, Encore says they only come in 1x6 or 2x6". I am stumped as to which size the ones in the photo are. I love the look. If this is a standard backsplash wall at 18" (maybe it's not) it seems these tiles would then be about 1.5" tall each as there are about 12 of them between the counter and cabinet. Help! And thx.
