Floating shelves are a stylish and practical addition to any home, offering storage and display space without taking up floor room. To ensure they’re safe, sturdy, and functional, it’s important to mount them properly so they can support the weight of whatever you plan to store.
There are three main ways to mount floating shelves: wall brackets, cleats, and lag screws.
Wall brackets use metal supports that attach directly to the wall and hold the shelf from underneath or within. Cleats are wooden or metal strips that mount to the wall and fit snugly inside the hollow back of the shelf for a clean, hidden finish. Lag screws, meanwhile, are heavy-duty fasteners drilled directly into wall studs, providing strong support with minimal visible hardware.
The right method for your project depends on your wall type (drywall, brick, concrete, etc.), the weight of the items you plan to store, and your preferred shelf design. In the sections below, we’ll break down each method step by step so you can confidently choose and install the best option for your space.
1. Using Wall Brackets
Wall brackets are one of the most common and reliable methods for mounting floating shelves. They work well with a variety of wall types, including brick, concrete, plasterboard, and timber. Wall brackets are relatively easy to install and offer a strong, secure hold — ideal for supporting heavier items.

Step-by-Step Guide to Mounting Floating Shelves with Wall Brackets:
- Gather your tools and materials: You’ll need: floating shelf boards, wall brackets, screws, a screwdriver or drill, a level, a pencil, and wall anchors (if needed).
- Choose the shelf location: Decide where you want the shelf to go based on both aesthetics and practicality. Make sure there’s enough space above and below the shelf for the items you plan to store.
- Check for hidden hazards: Use a stud finder or digital wall detector to check for hidden pipes, wires, or cables behind the wall. This helps avoid accidents or damage during installation.
- Measure and mark: Measure the spacing between the bracket holes on your shelf. Use a pencil to mark these measurements on the wall, ensuring they are level and evenly spaced.
- Drill pilot holes: Drill pilot holes at the marked spots on the wall for the anchors. If necessary, also drill matching holes into the back of the shelf for attaching it to the brackets.
- Install the brackets: Insert wall anchors (if required) and screw the brackets firmly into place. Use a level to double-check alignment.
- Attach the shelf: Slide the shelf onto the mounted brackets. Some designs allow the shelf to simply rest on the brackets, while others may require screws to secure the shelf in place.
Once mounted, your floating shelf should be sturdy and ready to use. Be sure to follow any manufacturer instructions specific to your shelf and use the correct type of anchors for your wall material. With everything secured, you can now style or store items on your new shelf with confidence!
2. Using Cleats
Another effective method for mounting floating shelves is using cleats. A cleat is a strip of wood or metal that attaches to the wall and acts as a support frame for the shelf. The back of the shelf is designed to fit snugly over the cleat, creating a strong, concealed mount.
Step-by-Step Guide to Mounting Floating Shelves with Cleats:
- Gather your tools and materials: You’ll need: plywood (for the shelf), wood for cleats, a saw, hammer, nails, screws, a drill or screwdriver, a level, and a pencil.
- Build the shelves: Start by cutting the plywood to the size you want for your shelves. Then cut wood strips to frame the edges and form a hollow box, leaving the back open so it can slide over the cleat. Assemble the shelf using nails or screws.
- Choose the shelf location: Decide where the shelf will go based on style and function. Mark the wall at the desired height, making sure there’s enough room for whatever items you plan to store.
- Cut the cleats: Measure the inside width of the hollow shelf and cut the cleat to fit. It should slide snugly inside the back of the shelf without forcing it.
- Mark mounting points: Hold the cleat against the wall where you want the shelf to go. Use a pencil to mark where the screw holes will be, ideally into studs for maximum strength.
- Drill pilot holes: Drill small pilot holes into the wall at your marked points. Do the same on the cleat if necessary, to make it easier to drive in screws without splitting the wood.
- Attach the cleats to the wall: Screw the cleat firmly into the wall using appropriate wall anchors or directly into studs. Use a level to make sure the cleat is perfectly straight.
- Mount the shelf onto the cleat: Slide the shelf onto the cleat. If desired, you can secure it with a few screws from the top or sides of the shelf to lock it in place.
Once installed, your shelf should sit flush against the wall with no visible supports — creating that clean, “floating” look. Just like with bracket-mounted shelves, always follow the manufacturer’s instructions and choose hardware suitable for your wall type.
3. Using Lag Screws
If you’re looking for a heavy-duty, minimalist option for mounting floating shelves — especially on stud walls — lag screws are a strong and reliable choice. This method involves driving long, thick screws directly into wall studs, then sliding the shelf over them so the screw shafts act as hidden supports.
This method works best with solid wood or custom hollow shelves that have pre-drilled holes to accept the lag screws snugly.

Step-by-Step Guide to Mounting Floating Shelves with Lag Screws:
- Gather your tools and materials: You’ll need: lag screws (usually 4–6 inches long), a power drill, level, measuring tape, stud finder, shelf with pre-drilled holes, pencil, and wrench or socket set.
- Locate and mark your studs: Use a stud finder to locate the studs in the wall. Mark their locations with a pencil — these are where your screws will go.
- Measure and drill pilot holes: Mark the placement of your shelf holes so they line up with the studs. Drill pilot holes into the wall and matching holes into the back of the shelf that align with the screw shafts.
- Insert the lag screws: Drive the lag screws into the wall studs using a drill or socket wrench, leaving about 2 to 3 inches of the screw shaft protruding.
- Mount the shelf: Slide the shelf onto the exposed lag screws, making sure it fits tightly. The screws should be snug inside the shelf for maximum support and a clean, floating look.
This method is very sturdy but works best for shelves that are at least 1.5–2 inches thick to safely accommodate the lag screws without cracking or splitting.
Quick Recap
Not sure which method is right for you? Here’s a quick side-by-side comparison to help you decide. This table highlights the key pros and cons of each mounting option at a glance:
| Method | Best For | Pros | Cons |
| Wall Brackets | Heavy items, solid walls | Strong, easy to install | Brackets may be slightly visible |
| Cleats | Clean look, drywall or custom setups | Invisible support, tailored fit | More effort to build and align |
| Lag Screws | Heavy-duty, stud-mounted shelves | Extremely strong, minimal hardware | Requires stud access and precise drilling |
Final Thoughts
There you have it — three different methods of quickly mounting your own floating shelves at home without needing professional consultation beforehand. Remember that practice makes perfect, so don’t be afraid to try out different styles and configurations to find one that suits your needs best before committing to the project.
But all things considered, everyone should be able to enjoy their own custom storage solutions now more than ever through simple yet effective methods like these today!
