How to Install Floating Shelves
Published April 28, 2025 · Updated March 1, 2026
Floating shelves create the impression of shelves unsupported by visible brackets. The key to a clean, professional install is accurate stud location and level mounting — both straightforward with the right tools.

Step-by-Step Instructions
Plan Height and Layout
Mark your desired shelf height with a pencil. For a series of shelves, standard spacing is 12-14 inches for books, 8-10 inches for small decor. Hold items you plan to store at different heights to test clearances. Mark both the centerline of each shelf and the brackets' positions along the length.
Locate the Wall Studs
Run the stud finder slowly along the wall at your shelf height, marking both edges of each stud. Studs are typically 16" apart on center. Confirm locations by driving a thin finishing nail at a slight angle — you'll feel solid resistance when you hit a stud, and no resistance (or the nail bends) in hollow drywall.
The "tape measure from corner" trick: in most homes built since 1980, studs are at 16", 32", 48", 64", etc. from the corner. This is a quick sanity check before running the stud finder.
Mark Bracket Hole Positions
Hold each bracket against the wall in its planned position. Where possible, align at least one screw hole over a stud mark. Use a level across the top of the bracket to ensure it's horizontal. Mark each screw hole location with a pencil dot.
For multiple shelves, use a laser level or a long straight board with a bubble level to ensure all shelves align on the same horizontal plane.
Drill Pilot Holes
For stud locations, drill a 3/32" pilot hole to the stud depth. For drywall locations, drill holes sized to match your anchor type (usually 1/4" for toggle bolts). Pilot holes prevent drywall crumbling and guide screws straight.
Drill only 3/4" deep at first — electrical wiring and plumbing pipes run through walls. If you feel unexpected resistance or the bit goes further than expected without biting wood, stop and investigate before drilling deeper.
Install Drywall Anchors
For any bracket holes that fall between studs, install appropriate anchors. Toggle bolts (bolt-and-spring-wing type) are the strongest option for drywall — they can support 50+ lbs each when properly installed. Snap-in plastic anchors work for lighter decorative shelves only.
For shelves holding anything heavier than decorative objects, rely on stud mounts only, or add wood blocking between studs (requires opening the wall). Drywall anchors alone should not support heavy books or kitchen items.
Mount the Brackets and Check Level
Drive screws into stud locations until brackets sit flush and firm. Check level with a 24" level across the top of the bracket (or across two brackets). Adjust by slightly loosening one bracket, tapping it up or down, then re-tightening.
Attach the Shelf Board
Most floating shelves have a hollow interior that slides over the bracket arms — simply slide the board onto the brackets. Secure from below using the bracket's provided screws driven up into the shelf base. For a permanent bond, run a thin bead of construction adhesive on the bracket tops before sliding the shelf on.
Verify Level and Load Test
Confirm the shelf is level one final time after attaching. Press down firmly at the center and edges to check for flex or movement. A shelf properly mounted into two studs with 3" screws can support 50-75 lbs per linear foot — plenty for books, plants, or kitchen supplies.
