Measuring for Square

Now that you know where you can safely dig, it’s time to measure out the area to make sure that your pergola will be square.

The traditional method of placing stakes or boards into the ground and extending mason string raised off the ground and along the extremes — is still the easiest and best way to get it right.

(In this diagram we have used red to denote mason’s string.)

  • Length 1: runs along the wall of the house the full length of the proposed construction. It should be exactly the same length as side 2.
  • Length 2: represents the outer beam of a parallel beam attached construction, and should be the same as length 1.
  • Length 3: is the distance the pergola will extend out from your home and should match length 4.
  • Length 4: is the distance the pergola will extend out from your home and should match length 3.
  • At this point we can measure the diagonals to make sure that our pergola building plan is square.

    When you are planning how to build a pergola — having a square construction is not only important to the look of the finished build, it’s stability and potential value — but will also make it a lot easier for you when you come to fitting beams and rafters of equal length.

    • Measure diagonally from corner a to corner d
  • Measure diagonally from corner b to corner c
  • If both diagonal measurements are the same you can be confident that your plan is square.
  • This is the same measuring method used for any like construction — including building a deck.
