Why you get less than the label says
Every strip is cut to the wall height plus trimming and rounded up to the pattern repeat, so a 33 ft roll on an 8 ft wall with a 21 inch repeat gives only 3 full strips, about 43 sq ft of wall. That is why the wallpaper calculator counts strips, not square feet.
