Select a material that complements your bookcase and suits your needs. Popular choices include:

  • Plywood: Sturdy, affordable, and easy to cut
  • MDF: Smooth surface, great for painting, but heavier than plywood
  • Hardwood: Durable and elegant, but more expensive

Calculate Shelf Size and Spacing

Easy way to add shelves to bookcases

Measure the interior depth, width, and height of your bookcase. Subtract the depth of the back panel (if any) from the interior depth to determine the maximum shelf depth. Decide on your desired shelf spacing (typically 12-14 inches) and the number of shelves you want.

Cut Your Shelves to Size

Using your measurements, cut your chosen shelf material to size. Ensure the edges are smooth and sand any rough spots.

Mark Shelf Positions and Drill Holes

Place your bookcase on a stable surface. Using a tape measure and pencil, mark the desired shelf positions on the inside of the bookcase sides. Ensure the marks are level and aligned on both sides. If using shelf pins, drill holes at your marks using a drill bit slightly smaller than the pin diameter. If using brackets, skip this step.

If you include the flooring and the fireplace build, this project has taken me just over a year to complete and I cannot wait for it to be done. Last time we left off, I had installed my cabinets and built four separate shelving units out of oak boards and I decided to stain my shelves to try to keep some natural wood on this project. I got the best looking thin plywood that I could find for the back of these shelves. I didn't want super thick plywood because then my shelves would stick out too far. I started attaching all my backs and realized very quickly that I was just building a playground attached. I also primed and painted all of these back pieces before attaching them so I wouldn't have to tape off my stained shelves to paint them later. After going through far more paint samples than I want to admit or that I ever want to see again, I finally decided on a color and went ahead and started priming and painting all of my cabinets. I usually like to prime by hand because primer can really clog up your paint sprayer and let's be honest, I just don't have my life together enough to clean my sprayer fast enough for it to not get clogged. So, I used a brush for the edges and then a foam roller for all the flat pieces to prime the cab and then I use my paint sprayer to spray the actual paint on the fronts and the backs. I attached all my shelves into the studs and the walls and now it was time to add some trim to make up for all of those uneven walls and maybe some mistakes. The one side of these shelves is exposed into the dining room so I decided to add a little bit of his shaker style trim around that side to give it a little bit more character instead of just a plain wall. Since no wall is ever straight, I had to use a level on every single one of these trim pieces to make sure that my trim was actually straight and not lining up against the wall and we'll fix that with the caulk later. Filling nail holes and caulking really isn't that bad but I was sick at the end of this project so this is probably my least favorite part of this entire process. This part and the rest of the painting really only took a couple days but since I was sick, it felt like an eternity. Now, before you come at me for painting this wood, I had to use a different type of wood on the trim pieces than I did for the shelves so if I stained them, they wouldn't match. I added battery-powered picture frame lights to the top of these units and then some gold handles to finish it all off. I am so happy to almost be done with this living room project. And I love how it turned out but I'm so ready to put my furniture back.

Attach Shelves Using Pins

If you're using shelf pins:

  1. Insert a pin into the bottom hole on one side of the bookcase.
  2. Place your shelf on the pin, ensuring it's level and flush with the front of the bookcase.
  3. Insert a pin into the corresponding hole on the other side of the bookcase, pushing it through the shelf.
  4. Tap the pin flush with the bookcase side using a hammer. Repeat for all shelves.

Attach Shelves Using Brackets

If you're using brackets:

  1. Position a bracket at your marked shelf position, ensuring it's level and flush with the back of the bookcase.
  2. Drill pilot holes through the bracket into the bookcase side.
  3. Secure the bracket with screws. Repeat for all shelves.
  4. Place your shelf on the brackets, ensuring it's level and flush with the front of the bookcase.

Test Your Shelves

Gently place a few heavy books on each shelf to ensure they're secure and level. Make any necessary adjustments.

Style Your Bookcase

Now that your shelves are securely attached, it's time to fill them with your favorite books and decor. Consider using bookends to keep books organized and add a decorative touch. Enjoy your new, customized bookcase!
