How many six-and-a-half-foot calligraphy works should I keep?

Arrange according to the number of words and the font you want to write, and then fold the grid yourself. When writing official script, you have to fold it horizontally. Writing regular script is square. Seal script is folded vertically a little longer. Ok, if it's grass, just fold the vertical line instead of the horizontal line. Six and a half feet of paper should be square, right? If you are a little professional, you should know that you have to calculate these before writing, at least you have to know well.
