Hi if I need to fence a distance measuring 20ft long do I buy 3x 6ft f

Hi Kate, don't forget to include the size of the fence posts (can be 3 inches or 4 inches wide). for 3 panels you'll need 4 posts which at 4 inches per post comes to 16 inches (just over a foot). You can probably cover up the remaining gap in a discrete manner depending on how the fence is situated. Hope this helps, Cheers Craig
