Tips for Using a Framing Square

Once you’ve chosen the right framing square for your project, here are a few tips to ensure you get the most out of your tool.

Clean the Square

Before using your new square, give it a good wipe down with a dry cloth to remove any dust or debris. This will ensure the numbers and graduations are clearly visible.

Check the Square

Before you start measuring, check the square for accuracy. Place the square against a straight edge to make sure all the numbers and graduations line up.

Watch Your Measurements

When measuring with a framing square, it’s important to make sure you’re reading the correct numbers. Make sure to double-check your measurements before marking them to avoid mistakes.

Store Properly

When you’re done with your project, make sure to store your framing square properly. Keep it in a dry, dust-free area to ensure it remains in good condition.

Having the right tools for the job is essential for any carpentry project. A framing square is an invaluable tool for measuring and marking straight lines and checking for square corners. When selecting a framing square, it’s important to consider size, material, accuracy, and comfort.
