How to Measure for Pile Caps

Properly measuring your wooden pilings ensures you get the right cap the first time. Even if all pilings were installed together, individual sizes can vary by 2–3 inches.

✅ Most Accurate Method: Use a String

1. Wrap a string tightly around the full circumference of the piling

2. Measure the length of the string in inches

3. Divide that number by π (3.1416) to calculate the diameter

4. Round up to the nearest half inch to select your cap size

Example:
25" string ÷ 3.1416 = 7.96 → Order an 8" piling cap

💡 You can also use a free circumference calculator online.

✅ Quick Steps Recap

• A. Wrap string around the piling

• B. Measure the string length

• C. Divide by 3.1416

• D. Round up to the next half size

🔎 Less Accurate Method (If No String)

If string isn’t available, use a tape measure to take two measurements:

• Measure across the piling North/South

• Measure again East/West

• Average the two and round up to the nearest half inch

Example: If a piling measures 8.3" x 8.1", order an 8.5" cap
