Hi, I believe this one is a 11x14 most are the 14x22 is the size I like to stay with. I have used the whole big size poster board but those take a lot more time and planning. I just tried the reverse on glass method and really liked the results haven't posted the outcome of that yet. I do have a Big Poster full size I did for the living room as it had a picture I didn't much care for and have switched it out. Have gotten a lot of compliments on it, and it was one of those pictures where everything just seemed to flow just right, in the zone so to speak and pulled it off well (haven't posted that yet am trying to get a good shot with little background reflection). Have to get to work have a great day and keep painting away
