Home Designs 101: How To Cut Chair Rail Corners Easily

Are you searching for steps that may help you know how to cut chair rail corners? Using a miter saw, cutting from an angle, from inside corners, and installing them, you will know the steps and information you need to cut chair rail corners.


Chair Rail Corners

Chair rails add detail to any room or area in the house that you install them in, but you need to get the cuts right to avoid uneven bars and edges for them to look astonishing. With miter saws, these can help you cut even and exact-angled cuts without having any worries. Although this tool can produce exact chair rails, there may still be wall corners tricky to get an identical piece.

These chair rails help you keep your wall undamaged from the back scratches that it may get from chairs. You may also install these as trims above your stairs, but cutting the angles may get complicated. A trick to perfectly cutting these rails is by trimming two short pieces.

The cost of these rails varies from the material that they have. The factors also include their shape and size depending on which ones are custom-made, making them even more expensive. You may find some made from synthetic components, while some have genuine wood.


Method #1. Using a miter saw

Step #1. With an adjustable-angle-square, measure the inside corner’s angles. Once you get the reading, divide it into 2, which will be the correct angles on each cut that you will make.

Step #2. Place your miter saw on the right angle, and set your first piece of rail on the platform. The angle should make the front trim shorter than the other side. Turn the miter saw on the same setting on the other part of the platform and cut the second piece, just like how you trimmed the first one.

Step #3. The board face must be longer than the back face, with a 45-degree angle cut for the outer corners. Exterior corner parts are easier to work with compared to interior components.

Step #4. For longer pieces, put 45-degree cuts that oppose each end of the rail, with one piece having a trim towards the face and the other towards the back.


Method #2. Cutting at angles

Step #1. Measure up from the steps of the stairs, marking each measurement on the wall on which you want the rail to rest.

Step #2. Hold one long piece of chair rail and press it against the wall as if you already installed it. The bottom of the piece must flush with the marked lines on the wall.

Step #3. Use a pencil and trace under the rail. The outlined line must extend past the following marked line on the wall and repeat the procedure until you reach the top.

Step #4. Cut two test pieces at 36 inches using the miter saw.

Step #5.  Align the two pieces against the wall, just like what you did with the long piece earlier, and let the other piece overlap with the other. You would now be able to see where you need to cut an angle. Mark the visualized angle with a pencil.

Step #6. With the marked piece, lay it flat on the miter saw and swing the blade right or left until it aligns with the pencil mark. Swing the miter blade on the opposite side and lock it at the same angle.

Step #7. Check if the pieces fit each other. If there is a gap, you can adjust the miter saw a degree shallower or sharper and cut the pieces again.

Step #8. Cut right-and left-hand angles with the same miter saw settings on the long pieces of chair rail.


Method #3. Cutting inside corners

Step #1. To cut the inner corner of a chair rail, insert it onto the miter box with the front face having to touch the back of the box.

Step #2. Hold the piece in your hand and, at a 45-degree angle, cut the end of it using a coping saw. Once you’ve done this to one corner end, do it with the corner as well.

Step #3. Mark and measure the part where you want to cut the rail, position it on the miter box with the plane face of it touching the back of the box. Cut at a 45-degree angle on the marked position.

Step #4. Repeat the steps above to cut the mating piece, which will be fixed together with the first piece.



Knowing how to cut chair rail corners can be quite difficult. Having a professional worker or someone of greater knowledge with this kind of work helps you make a huge difference on that difficulty. You may look for videos on the internet as a visual guide.

This house detail isn’t just an ordinary house detail. It protects your walls from harsh damage from chairs, and may also assist when someone walks up the stairs. It is indeed worth the effort to install and invest in!
