Step-by-Step Guide to DIY Arch Wainscoting

step 1- install the chair rail

To begin, Install the Chair Rail First

If you already have a chair rail, use it as the starting point for your wainscoting. If not, install one at 32 inches high to create a clean top edge.
Use adhesive and finishing nails for a secure hold.
A stud finder can help you attach it securely without unnecessary holes.

My chair rail was already installed where the slope of the ceiling hits the wall. So that’s where we’re starting with this project.

How to Determine the Size of Board and Batten

Before installing board and batten wainscoting, it’s important to plan out the spacing for a balanced look. Follow these steps to get the right measurements:

Measure the Wall Width – Use a tape measure to get the exact width of the wall where you’ll be installing the board and batten.
Decide on Your Layout – Choose how many vertical boards (battens) you want and the approximate spacing between them. A good rule of thumb is to keep spacing between 10-16 inches, but it depends on your preference. Mine is 15″ between the battens.
Calculate the Spacing – Multiply the width of one batten by the total number of boards you plan to install. Subtract that total from the wall width. Then, divide the remaining space by the number of gaps between the boards to get an even distribution.
Adjust as Needed – If the spacing feels too tight or too wide, tweak the number of boards or spacing slightly for a visually pleasing layout.

Taking time to calculate the right board and batten size ensures a professional, well-balanced look once installed.

step 2- Attach the Board and Batten Trim

Next, Attach the Board and Batten Trim

Cut horizontal boards at 90-degree angles for a simple board and batten wainscoting base.
Attach them below the chair rail and above the baseboard. These can also be used instead of the chair rail and baseboard.

Cut vertical boards at 90-degree angles for the board and batten wainscoting panels.
Space them evenly along the wall, ensuring they’re straight with a laser level.

Tip, use a stud finder when attaching the wainscoting to secure it into a stud when possible.
Secure each board using a Nail gun and 1-1/2″ Finishing nails

step 3- add the arches

And now, Cut and Install the Arch Details

Use a piece of baseboard trim to create the arch shapes.

Find the perfect curve by tracing a wood corbel from the store or using a stencil. Create two for each board and batten rectangle.

Cut out the arches with a jigsaw. Go nice and slow to perfectly cut the arches. Then smooth the edges with sandpaper.

Attach the arches between the vertical boards with a Nail gun, aligning them carefully for a seamless look.

step 4- finish work

To continue, Fill Gaps and Imperfections.

Apply caulk with a caulk gun to all seams for a polished, built-in appearance.
Wipe away excess caulk with a wet cloth before it dries.
Use wood filler for any nail holes, then sand smooth.

step 5- paint

Finally, Paint for a Finished Look.

Use semi-gloss or satin paint for a durable, easy-to-clean finish.
Two coats of paint will give the wainscoting a crisp, professional look.

after

I absolutely love how DIY Arch Wainscoting turned out in my playroom!

The arches break up the long expanse of drywall, adding interest and dimension to the space.

The curved details bring a soft, elegant feel that makes the walls look custom-built.

One of my favorite things about this project is the Moroccan-inspired touch the arches give the room. It feels a little more worldly and unique—especially exciting since I’m heading to Morocco soon!

Adding small elements like this is a great way to bring in inspiration from different cultures and make your home feel truly personal.

Time and Cost Considerations

Budget: For this project I spent $47 on the board and batten trim. $17 on the trim to make the arches. I had everything else on hand so this wainscoting cost $64. Not too shabby for a statement wall!
Time Commitment: This project can be completed in a weekend with the right tools.

If you’re looking for a way to enhance your walls with something beyond traditional wainscoting, DIY Arch Wainscoting is an affordable, stylish, and fun project to try!
