How to Build Modern Wood Shutters

One of the many steps in our exterior remodel was replacing the shutters. We chose a dark green vinyl siding  and I wanted shutters that would look good with our brown roof and match our wood door as well. My goal was a modern style that would grab someone’s attention and add some interest to the front of the house. After searching high and low for inspiration on Pinterest and Instagram, I decided on a thin slat wood shutter, and got to work designing and building!

I love the overall look, but will admit that I was a bit hasty on the stain decision. I made them before the front door was installed and never compared stain colors, so I will be refinishing them this spring to match the door and address plaque. All in all, it was a relatively easy project (as long as you have the right equipment) and made a huge difference in the curb appeal of our home. We’ve gotten a lot of compliments from visitors and neighbors on their unique and modern look!

Want to build your own wood shutters?

You’ll need:

  • tape measure & pencil
  • miter or circular saw
  • dimensional lumber- we used 1’x8″ boards
  • nail gun
  • wood glue
  • stain (one mixed with Poly is ideal)
  • square
  • sanding sponge

How to:

1 | Measure the height of your window from the top of the frame to the bottom of the frame.

2 | Determine the width you’d like for the shutter; on average, a window at least 30 inches wide will have a 15 inch shutter. Windows wider than 36 inches may have wider shutters- up to 18-20″. The best way to determine the size you like is to use painter’s tape to tape out the size of the shutter next to the window.

3 | Calculate your lumber needs. We used two vertical 1″x8′ boards and 20 horizontal slats for each shutter and multiplied by 4 for all of our shutters, bringing us to 20 1″x8’s.

4 | Measure and cut two vertical boards at the height of the window.

5 | Using your miter saw or circular saw, cut the horizontal slats- we went with a width of 16″.

All of the horizontal shorter boards cut and ready to install- 50 in total.

6 | Lay out the short boards on top of the vertical boards to determine the spacing you’d like to achieve between each board. This will take some math! My shutters used 20 horizontal boards with a roughly 3/16″ gap between each one.

Boards laid out to determine the desired gap between them.

7 | Make a small circle of glue on either the short or long board. Lay the board on top of the vertical boards and use your square to straighten the board up to the vertical board.

8 | Using your nail gun, put two nails in each side of the short board. Josh got me started and then I finished up the rest of them!

9 | Repeat steps 7 and 8 but lay the board at the bottom of the longer boards to create a solid frame.

10 | Install your next board at the desired distance from the board above it, repeating steps 7 and 8. It helps if you can find an object that is the width of the gap you want- I used a notebook! Repeat this until the entire shutter is complete!

11 | Sand the visible sides of the shutter as smooth as possible using your sanding sponge.

12 | Stain every visible piece of wood- I used a foam craft brush and it worked great. I used a stain/poly mix and it worked great, although you could certainly stain and poly separately if the stain color you wanted wasn’t available as a mix. I don’t have any photos of this step, sorry!

13 | When all of your shutters are complete, it’s time to hang them! While I held them in place next to the window, Josh drilled a hole in the top two corners. He then put a 2″ construction screw through each hole and repeated the process in the bottom of the shutter.

Although the color isn’t quite perfect next to our front door, I love our wood shutters and have gotten many compliments. They add a modern look while also adding some depth and interest to our exterior. We plan on adding window boxes this summer and had done some landscaping last summer so I can’t wait until everything grows back in!

  • Hi, love the way these look and hoping to do some myself in the next week or so. I was just wondering how the stain has worked out in the sun(summer heat)? With such thin boards have they warped at all or changed in color/lost their stain, been damaged at all?

    • Hi Bree! Thanks for your comment- great question. I actually ended up taking them down to refinish them (to match the new door we put in) and ended up leaving them down. The boards weren’t that thin- they were about 3/4″ thick if I remember right. The front of our house is very shaded so they wouldn’t have been exposed to direct heat anyway. As for the finish, it depends on what you use to finish it- a good outdoor poly should ensure that you don’t have any issues with fading!
