Metric Wainscoting Calculator — Easy DIY Wall Panel Planning in cm

Welcome to the Metric Wainscoting Calculator — the simplest tool for planning and measuring wainscoting panels and picture frame molding using centimeters and millimeters. Whether you’re installing decorative wall panels, shadow box wainscoting, or picture frame molding, this calculator helps you quickly find the right panel widths and spacing for your wall.

Use this tool to:

  • Calculate how wide each wainscoting frame will be in cm

  • Evenly space panels on walls of any length

  • Plan your DIY wainscoting layout with confidence

What Is Wainscoting?

Lambrisering is a decorative wall trim that covers the lower part of a wall to add character and protection. It commonly uses evenly spaced panels, rails, and stiles to create a polished wall finish. Designs include recessed panels, shadow box/molding frames, beadboard, and board and batten styles.

Why Use a Metric Wainscoting Calculator?

Most wainscoting plans and calculators online use imperial units (inches and feet). That can make planning a metric DIY project tricky — especially when you want dimensions you can use directly with a tape measure in cm or mm. This calculator was built for metric builders and makers who want accurate, intuitive results in the units they’re actually using.

How the Metric Wainscoting Calculator Works

  1. Enter Wall Width in cm — the total horizontal length of the wall where you want wainscoting.
  2. Enter Spacing Between Frames (Stiles) — this is the vertical divider spacing between each panel, measured in cm.
  3. Enter Number of Wainscoting Frames — how many individual picture frame panels you want across your wall.
  4. Calculator Output — shows the width of each panel so that the frames are evenly spaced and balanced across your wall.

    This helps you eliminate guesswork and avoid uneven panel widths.

Tips for Measuring and Planning Your Wainscoting

  • Measure Carefully: Always measure wall width in centimeters from one edge to the other. Include corners and baseboard if you’re framing around obstacles.

  • Choose Your Panel Style: Decide whether you’re using simple picture frame molding, recessed panels, or board and batten — each affects how you calculate spacing.

  • Consistent Height: Standard wainscoting height is often around ~80 to ~100 cm from the floor, but you can adjust this based on ceiling height and design preference.

  • Spacing Matters: Equal panel widths with consistent spacing create a balanced look, so use the calculator to test different frame counts until the layout looks right.

Common Questions

Can I use this for board and batten style?

How do I choose the right spacing (stile width)?
A general starting point is between 8–12 cm for standard panel aesthetics, but you can adjust based on the style finish you want.

In this post I’m going to go over installing the wainscoting frames and the tips and tricks I found while installing them.

Okay, so you’ve figured out the measurements of your wainscoting frames, and you know how to cut the pieces of the frame.

Well here we’re going to go over how to install the wainscoting frames.

Installing the wainscoting molding is a pretty repetitive task, but with the right tools and these tips and tricks you’ll get through it in no time.

Stap 1 – Make Sure Your Wainscoting Measurements are Right

The last thing you want is to cut all your pieces, then find out you cut the pieces too short!

This is what I did to give me some piece of mind.

Once I have the bottom pieces cut, I bring them to the wall they’re going to go on and lay them out on the floor along that wall spaced out the way they’ll be spaced out once they’re installed.

I wanted to make sure my measurements for the wainscoting frames were spot right. With my Wainscoting frames I decided to use 3 1/2″ spaces between the each frame. I did that because it looked nice, but it’s also the width of a regular 2 x 4, so it was easy to find a spacer. If you look in the picture below, I used a 2 x 4 to space the bottom pieces out on the floor.

If you want to use a different spacing you can just cut a piece of 1×4 or 1×6 to the right width and use that as your spacer.

Paint First Or Frame First?

I don’t think the order matters too much. We painted the walls first then we installed the frames. We felt like we needed to paint the walls first because we were dying to see what the colors would look like on the walls.

As you can see from the pics, we didn’t paint it anywhere near perfect. We knew full well we were going to have to paint for real afterwards, but we did a rough single coat of paint to get an idea of the colors.

Should You Start From The Top Or Bottom?

My first attempt at wainscoting was a few years ago on the ground floor of this house.

When I did the wainscoting on the ground floor I started with the chair molding that goes along the top, then I did the horizontal molding underneath it and I then filled in the space below it with the wainscoting frames.

When I did it this time around, I decided to install it from the bottom up.

Ultimately, I think it’s really just a matter of preference, but installing wainscoting from the bottom up is much easier.

The biggest difference between the two is that I can do most of the installation just by using the spacer, when starting from the bottom. Put the spacer on top of the baseboard, install the bottom of the wainscoting frame. Then build up the box, put the spacer on the top of the frame and install the top horizontal molding, and finally put the spacer on top of the horizontal molding and install the chair molding at the very top.

When I started from the top there was a lot more measuring and leveling and measuring and leveling to get that chair molding just right.

How To Start The Wainscoting Frame

It’s really much easier than you would think. The key is using the spacers, they allow you to get everything done without too much measuring.

The one thing I’d like to also mention is everything does not have to be perfect, perfect. You don’t need to make sure every single piece is absolutely level.

Let’s just say this. When you do your very first wainscoting frame you are going to measure and level 1000 times more than you will the 500th frame. 🙂

If you start from the bottom and work your way up and use your spacer to keep the space around each frame consistent, the only pieces that you need to really check for level are the very top horizontal pieces.

The wainscoting in the stairs was a whole other animal!! The wainscoting in the stairs deserves it’s own post but when you are doing the wainscoting on a regular wall, the actual install goes pretty smoothly.

Tip: Two things – First You NEED to use a nail gun to do this project. I can’t imagine doing this with a hammer.

Second I used nails to keep the frames in place but I also used a painters caulk on the back of the molding to help them be a bit more secure. It helps when doing the second vertical piece and the top piece.

The Order To Installing the Wainscoting Frame Pieces

This is the installation order when installing your wainscoting frame:

1– Install the bottom leg by putting caulk on the back of the leg, then nailing both ends of that leg to the wall.

2– Add caulk to the back of the right leg then nail both ends of that leg to the wall. I also like to add a little caulk in the miter joint before putting the pieces together.

3a– Caulk the back of the left leg and nail in the bottom of that leg

3b– Caulk the back of the top leg and nail in the right side of that leg

4a and 4b– Line up the top of the left leg and the left of the top leg so they are nice and tight together, then nail in both

That’s pretty much it! Rinse and repeat… a lot and you’re done. 🙂

Below are the details for each installing each of the legs.

 

DIY Wainscoting - The Frame Pieces Installation Order

Stap 1 – Installing The First Wainscoting Piece

Okay, here we go, we are installing the picture frame for your wainscoting!

Natuurlijk, you want to start at one of the ends of the wall. If there’s a doorway on one end, that is where I started.

Place a spacer vertically AND horizontally, giving you the right spacing on the bottom and the side. Once you have it nice and snug use your nail gun to nail in the piece.

Woohoo! You installed your first wainscoting piece! That wasn’t so hard right? It’s basically a lot of that. 🙂

 

 

Installing the first Picture Frame Piece

Stap 2 – Installing The First Vertical Piece

This is going to be the vertical piece that is either against the wall, the doorway, or the last frame you just finished.

Place your spacer against the wall, doorway or last frame you just finished, place the molding against the spacer and snug against the corner from the bottom piece and nail it into place.

 

Installing the second Picture Frame Piece

Step 3a – Installing The Second Vertical Piece Bottom Corner -ish

I say “-ish” because I don’t completely install this piece in. Installing this piece a bit more complicated than the first two pieces.

Since there isn’t anything to put a spacer against, you’ll need to use the level to nail in this piece.

Place the second vertical piece in place and the level vertical against it. Now adjust its position left and right until it looks level. Once it’s pretty level, nail in the bottom of the molding.

Leave the top of the piece unnailed so it can be adjusted when we put in the next piece.

Full disclosure – This picture is the previous one I flipped vertically. I took so many pictures – yet I missed taking a pic of the right piece getting installed! 🙁

On to the next step!

 

Installing the third Picture Frame Piece

Step 3b – Nailing In The Top Piece First Corner

Now we install the top piece. Put the piece in place, snug on the top corner of the vertical molding that is nailed completely and loosely on top of the piece on the other side.

Use the level to make sure things aren’t completely off, again if it’s off a little it is not going to ruin it. This is just to make sure you’re in the right ballpark.

Once it looks pretty level, nail in the piece on the end that’s touching the vertical piece that is completely nailed in.

You’re almost there, the last part of the frame is coming up.

 

Installing the top Picture Frame Piece

Stap 4 – Nailing In The Last Corner

It’s now looking like a picture frame, the only thing left is to nail in that last top corner.

Here you can micro-adjust so the last corner looks tight, the the top piece is level-ish and the second vertical piece is plum-ish.

Once it looks pretty good, finish nailing in the two pieces that make that corner.

Woohoo! You did it! That is your first wainscoting frame.

Now it’s just a matter of repeating it over and over again. 🙂

 

DIY Wainscoting Nail In The Two Pieces For This Corner

Installing the Middle Molding

The space above the wainscoting picture frames and the middle molding in my layout was 3 1/2″, the same as the space between the picture frames, so I used the same 2×4 spacer for this spacing too.

To install the middle molding, I laid the 2×4 on top of the picture frame, put the middle molding on top of it and nailed it in. Before nailing it in I added painters caulk on the back of it.

Installing the Top Molding (Chair Molding)

The space between the middle molding and the top, chair molding is 3″, so I took a piece of 1×4 and cut it to 3″ wide and used that as the spacer.

To install the chair molding, I put the spacer on top of the middle molding, then nailed in the chair molding. Opnieuw, similar to the middle molding I put caulk on the back. It gives it more support and helps keep the molding in place while I nail it in.

Installing Wainscoting Around Outlets

When you’re installing your wainscotting you’ll come across obstacles on the wall that will sometimes force you to customize the wainscoting picture frames. Outlets are one of those obstacles.

Sometimes you’ll get lucky and the outlet will fall outside the path of your picture frame install, but more often than not they’ll be smack dab in the middle of your way.

When I was dealing with the outlets there were a couple of ways I did it.

Notch The Wainscotting Piece

You can notch out the picture frame piece to fix the outlet and the cover that will go over it. Notching is only an option when the outet/cover are only partially in the way of the picture frame.

If the outet/cover is more than a little in the way, I think it looks better if you do the next option, cut it in two.

When cutting the notch out I used the miter saw to cut the top and bottom parts of the notch, then used a utility knife to cut from the top cut to the bottom. Since the molding is PVC it’s pretty easy to cut into.

Cut The Wainscotting In Two

You can cut the picture frame piece in two. If the outlet or it’s cover is completely in the way of your wainscoting frame, then you’ll have no choice but to cut the wainscotting piece into two pieces.

When cutting the piece in two I call then end at a 45 degree angle so it looks more finished and eases the transition from the wainscoting frame to the outlet and back again. If it were a 90 degree cut I think it wouldn’t look as finished.
