How to Measure for a Fence: The Step-by-Step Method

Bad measurements are the #1 reason fence projects come in over budget. The fix takes an afternoon, a long tape measure, and some stakes. Do this before you talk to contractors or run the calculator.

What you need

• 100-ft tape measure (or open-reel surveyor's tape)
• 12–20 wooden stakes
• Hammer
• String line (mason's line) for straight runs
• Notepad — sketch your yard from above and label every measurement

Step 1: Find your property lines

Don't guess. Use your plat survey if you have one, look for survey pins at the corners (small metal stakes), or hire a surveyor for $400–$800. Building 1 foot inside the line is fine; building on the line risks disputes.

Step 2: Stake every corner

Drive a stake at each corner of your planned fence run. Include any direction changes — every corner becomes a corner post in your final estimate.

Step 3: Measure each straight run

Stretch the tape from stake to stake. Write the number on your sketch. Don't sum runs in your head — write each one separately and add them up at the end.

Step 4: Mark gate locations

Decide gate locations now. Each gate adds a post and modest hardware cost. Standard pedestrian gates are 4 ft wide; driveway gates 10–12 ft. Stake both sides of each gate.

Step 5: Handle slopes

If your yard slopes more than 6 inches per 10 feet, you have a decision: stepped panels (each panel level, with steps between) or racked panels (panels follow the slope). Stepped costs less and looks more formal; racked looks more natural. Either way, your linear footage is the same — the math works.

Common measurement mistakes

1. Measuring along the ground on a slope instead of horizontally (overestimates run length)
2. Forgetting return sides (most yards need fence on three sides, not just the back)
3. Counting the house wall as 'fence' — it isn't; subtract that length
4. Not adding gate width to the linear feet — gates ARE fence
