When it comes to sewing and quilting, achieving neat and professional-looking corners is essential in creating a polished finished product. One technique that can be used to achieve these corners is mitering. Mitering refers to the process of folding fabric at a 45-degree angle to create a diagonal seam that eliminates bulk and creates a crisp corner.
What Is Mitering?
Mitering is a technique that is commonly used in sewing and quilting to create sharp corners that are neat and tidy. It is used in a variety of projects, including table runners, napkins, and quilt borders. Mitered corners can also be used in garment making, such as collars and cuffs, to create a more professional and polished look.
The Formula for Mitered Corners
Calculating the correct size of fabric needed for mitered corners can be a bit tricky, but there is a formula that can be used to make it easier. The formula for mitered corners is:
Length of Fabric = Desired Finished Size + (2 x Seam Allowance) + (2 x Hem Allowance)
Let’s break down what each part of the formula means:
- Desired Finished Size: This is the size that you want your finished project to be. For example, if you are making a napkin that measures 18 inches square, your desired finished size would be 18 inches.
- Seam Allowance: This is the amount of fabric that is folded over and sewn to create the seam. The standard seam allowance is 1/4 inch, so you would multiply the seam allowance by 2 to account for both sides of the corner.
- Hem Allowance: This is the amount of fabric that is folded over and sewn to create the hem. The standard hem allowance is 1/2 inch, so you would multiply the hem allowance by 2 to account for both sides of the corner.
Once you have calculated the length of fabric needed, you can cut your fabric to the correct size and begin the process of mitering the corners.
How to Miter Corners
Now that you know the formula for calculating the length of fabric needed for mitered corners, let’s dive into the process of actually mitering the corners.
- Start by folding the fabric at a 45-degree angle, right sides together. The fold should be at the corner of the fabric.
- Use a ruler and a fabric pen or pencil to mark the seam line along the fold. The seam line should be the same length as the desired finished size of your project.
- Sew along the seam line, being careful not to sew beyond the marked line.
- Trim the excess fabric, leaving a 1/4 inch seam allowance.
- Press the seam open, and fold the fabric over at the corner, right side out.
- Finish the hem on the remaining sides of the fabric as desired.
By following these steps, you can create mitered corners that are neat, tidy, and professional-looking.
Conclusion
Mitered corners are a popular technique used in sewing and quilting to create sharp, polished corners. By using the formula for mitered corners and following the steps for mitering corners, you can achieve a professional look in your projects.

Frequently Asked Questions for What Is The Formula For Mitered Corners?
1. What is a mitered corner?
A mitered corner is a technique used in woodworking, sewing, and construction to join two pieces of material at a 45-degree angle. It is commonly used in making picture frames, door and window frames, and quilting.
2. Why is it important to know the formula for mitered corners?
Knowing the formula for mitered corners helps to ensure that the angle is accurate, and the joint is strong and precise. If the angle is not correct, the joint will not be tight, and the piece may not fit together correctly.
3. What is the formula for mitered corners?
The formula for mitered corners is the length of the material divided by the square root of 2, then multiplied by 2. This will give you the length of the material needed to make a mitered corner. For example, if the material is 12 inches long, the formula would be (12/sqrt(2)) *2 = 33.94 inches.
