To calculate the number of panels you will need to order for your project, choose the length based on the vertical height of your wall.  Each panel is 24 inches wide, so divide the total width of your wall by 24 inches to calculate the number of panels your wall will require.  Round up to the nearest whole number.
 For example, if your wall is 210 inches wide, divide by 24, which equals 8.75.  Round up to the nearest whole number (9), which means you need 9 panels.  If you have any questions please don't hesitate to ask! We're always available and more than happy to help.
