Are you thinking about installing a grid accent wall in your living room or bedroom and need a little guidance? You’ve come to the right place! We recently completed a beautiful grid accent wall for a client, and have plenty of tips to share. A grid wall, also called a board and batten wall, takes a little planning and require some basic math, but the installation part is actually quite easy to do. We love sharing tips & tricks with other DIY-ers, so we put together a detailed tutorial for you to follow to create a perfect grid feature wall in your home.

Step 1 – Plan Out the Grid Wall

Yep, this project takes a little extra planning before you get started. But, we’re gonna break it down for you into a couple of easy steps.

1. Measure Your Wall

The first step in creating your board and batten grid wall is to measure the width and height of your entire wall in inches, which we will refer to as W and H going forward. Bust out your tape measure and measure the width and height of your wall. For the width, you may want to measure at the bottom and again near the top of the wall just to see if there is any significant difference (not all walls are even or straight). Same goes for the height.  

2. Choose Your Materials

Next, you will need to know the width of your grid lines. In other words, you will need to determine if you want to use 1×3 boards, 1×2 boards, or even 1×4 boards for your materials. The width of the boards will come into play in Step 3 (below) when installing your vertical boards.

Tip: We prefer to use 1×3’s. The reason for this is purely aesthetic. The 1×4’s can end up looking a little chunky, while the 1×2’s can look too skinny on a large wall. For really small walls, however, we would recommend using 1×2’s.

For a wall like this, 1×3 MDF boards are a great choice. Not only is it an inexpensive product, but having boards that are already primed will save you some time. You can also use 1×3 primed finger joint boards, or unprimed select pine boards for your grid wall.

3. Calculate Your Squares

The key to a perfect grid wall is to make your grids as close to squares as you can. Since your wall width is unlikely to be the same height as your ceiling, this can be a little tricky. We like to have our squares ideally be about 16-24″ on a side. Anything smaller can end up looking too busy. If the squares get too big, they just look, well…too big.

If your wall width or height happen to be an even number, like 8 ft, just divide by 2 ft to determine the number of squares you will have in either direction. If your wall width or height is an odd number, you will have to get a little more creative. We came up with a handy table to take all the guesswork out of it for you:

OK, now let’s check our grid spacing with an example. Suppose your W measurement is 11 ft wide (132 inches) and your H is 8 ft high (96 inches). According to our table, we should end up with a grid that is 6 squares wide by 4 squares high. Each square will be 22 inches wide and 24 inches tall. That’s pretty darn close to a perfect square!

Now that you have a good plan for your grid wall, you can calculate the number of boards you’ll need and head out to your local lumber yard, hardware store, or Home Depot for all of your supplies.

Step 2 – Install the Frame

The next step is to install your top and side pieces. Along with the baseboard, this will create a “frame” for your grid wall. If you were also planning to replace your baseboards for the grid wall, install the new baseboards now, too.

If you’d prefer to use your existing baseboard, and want to see some examples of how to integrate the vertical pieces with the baseboard, check out our Grid Wall Baseboard Examples. After this step, your wall should look like this.

Step 3 – Install the Vertical Pieces

We like to install the vertical pieces first. There are two reasons for this. The first is that most of the time, the width of the wall is wider than the height of the wall. If we installed long horizontal boards first, we would then have to install lots and lots of little vertical pieces. Installing it the other way around (the vertical pieces first), we have fewer little horizontal pieces to cut and install.

The second reason is purely for convenience. We like to avoid carting home long pieces of wood from the lumber yard or big box stores whenever possible. Since most ceilings are 8 ft high, we can buy 8 ft pieces of wood for our vertical grid line installation, and avoid having to buy and manage several really long boards.

That being said, you will probably have to buy one long piece of wood for your top horizontal header, and another for your baseboard (if you are replacing them). Buying two long pieces is more convenient in our opinion, than buying 5 or 6. Purely a personal preference.

When installing your vertical boards, we like to use our trusty nail gun and some construction adhesive or liquid nails applied to the back of the board. If you’re installing into drywall, you can also angle your nails (some pointing up, and some pointing downward) to better anchor your wood pieces into the drywall.

A little more math…

OK, time for a little more math. The distance between the edges of your vertical pieces is not going to be exactly the same as the square spacing we provided in the table above due to the width of your wood. So, how do you figure out the space between your vertical wood pieces? Here is the formula:

grid wall spacing

OK, so if you hated math in school, that formula may have made you want to quit this project before you even started. Don’t quit now! Let’s walk through it together using our example wall, shall we?

Our wall is 132″ wide, and we have divided it into 6 squares. With 6 squares, we will actually be using 7 vertical boards across the wall (# squares + 1). Each 1×3 board is going to be 2.5″ wide (because that’s how wide a 1×3 board is). If we multiply 7 times 2.5″, we get 17.5″. That’s how much space our boards are going to take up on our wall. If our wall is 132″ wide, and the wood will take up 17.5″, we are left with 114.5″ of wall. Divide that up into 6 squares, and you have just a hair over 19″ between each piece of wood. Phew, you made it!

Let’s see what this looks like on our example wall.

We like to install our vertical pieces using a 4 ft level (a laser level would also work great) to make sure the vertical grid lines are straight. The reason this is important is because your walls may not be perfectly straight. In fact, the width of your wall at the ceiling could be slightly different than the width of your wall at the floor! If this surprises you, just know that this is really common in houses.

Step 4 – Calculate Your Horizontal Spacing

OK, remember that math we just did for the width of the wall? Well, you need to repeat it for the height of the wall, too. In this case, just make sure you take into account the width of your baseboard, as it is probably wider than the 1×3 boards you will be using.

For our example wall, it looks like this… 96″ (ceiling height) – 10″ (the width of 4 1×3 boards) – 5.25″ (the width of our baseboard). That gives us 80.75″. Now we need to divide that by the number of vertical squares we will have, which is 4. That gives us 20 3/16″.

Step 5 – Create Two Spacers

OK, now this is the absolute key to installing your DIY grid wall! It will save you so much time, and make the entire rest of the installation a breeze. Listen up!

Cut two pieces of wood that are exactly the length of the horizontal spacing you calculated in Step 4. For our example wall, the two wood pieces would be 20 3/16″ long. You are going to be using the two pieces of wood as spacers for installing the remaining horizontal pieces of your grid wall.

These spacers will not only ensure that your grid pieces are straight, but that each piece is at exactly the same height as the grid piece on either side of it.

Step 6 – Install the Horizontal Pieces

Use your spacers to install the horizontal pieces, like so…

You can start from the ceiling or the floor, but just make sure to start from the same place for each column of your grid wall. Be sure the measure carefully before cutting your horizontal boards to ensure you don’t end up with large gaps that are difficult to fill (next step).

Step 7 – Fill Nail Holes & Caulk

I’m not gonna lie to you, there is a lot of caulking to do with a grid wall. You will need to caulk every square in the grid, along with the seams where your horizontal pieces meet your vertical pieces, and where your grid frame meets the ceiling and side walls. I highly recommend you get yourself a caulking gun, if you don’t already have one. Oh, and make sure to fill all the nail holes with some light spackling paste or wood filler and sand smooth before painting. You’re almost there!

Step 8 – Paint & Enjoy!

This is where the magic happens, and all of your hard work pays off…FINALLY! Pick a fabulous bold paint color or go with classic white. After two coats of paint, you will have the most gorgeous grid wall, and the final result will be worth all the effort! For this wall, we chose Sherwin-Williams Black Fox. You’re just a few brush strokes away from completing your diy grid accent wall! 

Be sure to sample your paint colors on your wall before committing to one. I highly recommend purchasing some inexpensive, and super easy peel-and-stick sample sheets from Samplize. If you need recommendations for designer-favorite paint colors, you can check out my Favorite Paint Colors eBook.
