I’ll be frank- I was excited about this, but I was apprehensive, bc the reviews/vids on peel and stick wallpaper are SO MIXED.First off, square footage of ONE wall is simply width times height (may seem obvious but in case anyone is wondering :)So... get the correct number of rolls.For instance... ONE of my walls is approx 9 ft tall and 8 ft in width so that would be 72 sq. Ft. Hence, for this specific wallpaper... I’d need four rolls. I will have extra obviously.Many vids and reviews I’ve read say... it’s tricky, it takes a while, you need more than one person....Um... I literally was psyched to check it out and I just took it out right when it arrived earlier and rolled it out on the floor and measured a little over 9 ft (the height of my ceiling) - cut it with scissors and put the first strip up. It was easy and fine. It’s not hard and it looks great. I have no idea what everyone is talking about.My walls are plaster and they are not even smooth.There are no bubbles and it was easy.I started from the top and smoothed it as I went down. I stood on a stool bc i am not 9 ft tall.This pattern is quite forgiving.I will post a photo when I’m done. I’ve only put up one roll so far bc I’m lazy but it took me ten minutes:)Oh one thing I will say which I remember reading in another review is there is a strong smell of plastic. So be aware of that. Good luck!
