Fence Calculator

Building a fence requires more than just picking a style - you need to know exactly how many posts, rails, pickets, and fasteners to purchase before you start. This fence calculator takes your total fence length and height and breaks down every component, so you can create an accurate shopping list and budget before heading to the lumber yard.

The calculator supports common fence styles including privacy, picket, and ranch rail. Enter the total linear footage of your fence line and the desired height, and it computes the number of posts (with configurable spacing, typically 6 to 8 feet), horizontal rails per section (usually 2 or 3 depending on height), pickets with adjustable gap spacing, and gate openings. It also accounts for corner and end posts, which need to be set deeper and may require larger dimensions.

Beyond quantities, the tool provides practical guidance on post depth (typically one-third of the above-ground height plus 6 inches), concrete per post hole, and total board feet of lumber. Whether you are installing a backyard privacy fence, a decorative garden border, or a ranch perimeter, this calculator ensures you order the right materials the first time.
