Measure Total Perimeter and Subtract Gate Openings
Start by measuring your property lines to establish the total linear footage needed. Next, identify exactly where your gates will go and subtract the width of those openings from your perimeter measurement. Whether you want a 4-foot walk gate or a 10-foot double-drive gate, deduct that total span first to calculate the exact footage of continuous fence run you must cover.

Calculate Posts, Panels, and Hardware
Divide your remaining linear footage by standard section lengths (typically 6 or 8 feet) to determine how many panels or pickets you need. To find line post quantities, divide your run length by post spacing and add one extra end post per straight stretch. For gates, always allocate dedicated gate posts designed to support hinge loads. Ordering your wholesale fencing supplies directly ensures every hinge, latch, cap, and bracket matches your specifications.

Factor in Gate Allowances and Waste
Gates require specific structural allowances for clearances, hinges, and latches—usually 1.5 to 2 inches of total clearance between the gate frame and supporting posts. When ordering raw lumber, vinyl profiles, or chain link, always add a 5% to 10% contingency buffer to your order to account for cuts, terrain slopes, and scrap.
