How do you square a foundation with batter boards?
From an outside corner, measure 3 feet along one line, and make a mark on the string. Measure 4 feet along the other line, and make a mark on the string. Measure the diagonal distance between the two marks and adjust the stakes as needed so the distance is 5 feet. Repeat the squaring process at all corners.
Should batter boards be level?
Always use a line level to ensure all lines strung are level. After taking out the area, double-check for squareness by measuring the diagonals between opposite corners. They should be equal. When deeper trenches must be dug for wall and foundation footers, it is best to lay out batter boards.
Why do batter boards need to be level?
They can be used to measure and mark off the exact position of doors, windows, and floors, thus making it much easier to build the walls accurately. To be useful, batter boards must be exactly level and should be set about 1 meter back from the string marking the outside foundation line.
How does a batter board work?

Why is it important to know the steps or procedures in batter boards?
It is probably the most critical step in the entire construction process. A building that is set out carelessly will be difficult or impossible to construct according to plan. As a result, the finished structure may be expensive to maintain and unhealthful. So it is important to take special care when setting out.
What should be the distance of the batter boards from the building line?
Locate the batter boards 4 feet or more away from the building lines. In most cases you want to make sure your batter boards have enough room for you to move your lines while you try to square the building. So, place your stakes at least 4 feet apart from each other and use batter boards that are at least 5 feet long.
How big of a hole do I need for a 4×4 post?
The diameter of your post hole should be three times the diameter of your post. So, if you’re planning on using a four-inch round or 4×4-inch square post, your post hole will need to be 12 inches in diameter. For a six-foot-high fence post, we would need a hole that’s 36 inches deep and 12 inches in diameter.
How do you square a Masonic line?
MAKE A 3-4-5 TRIANGLE With a tape measure, check that the corner is square by making a 3-4-5 foot triangle. Adjust the mason’s line as needed until the distance between two points equals 3-feet, the other edge equals 4-feet and the edge opposite from the corner stake is exactly 5-feet.

To get a perfectly square corner, you want to aim for a measurement ratio of 3:4:5.
