How many fence posts and panels do I need?
The number of posts depends on your fence's total perimeter and how far apart you space them — typically 6 to 8 feet for wood fencing, though this varies by fence style and local building codes.
Panels are usually sold in standard widths, most commonly 6 or 8 feet, so the number you need depends on both your total fence length and the panel width you choose.
Remember to measure your fence line's full perimeter, including any gates, and account for corner posts separately if your yard has an irregular shape.
