What is the correct method to square up a wall during framing?

To square up a wall during framing, the method of measuring diagonals is widely accepted as accurate and effective. This technique involves measuring the distance between opposite corners of the wall framework. If the wall is perfectly squared, both diagonal measurements will be equal. This method leverages the properties of a right triangle, making it an essential practice in construction to ensure that frames are not only straight but also accurately positioned.

While other methods may contribute to the alignment of a wall, such as using a level or a square, these tools do not provide the same level of confirmation regarding the squareness of the wall in relation to the foundation. Measuring the total length may indicate that the wall is constructed to the correct dimensions, but it does not verify if the angles at the corners are correct. Therefore, measuring the diagonals is the preferred method to ensure a properly squared wall.
