How to install floating shelves so they actually hold weight

Stud-mounted or drywall-anchored — what to use, what to skip.

Last reviewed May 31, 2026 by the EveryDIY.ca editorial team

1 hour per shelf $30–$80 CAD CAD pricing

What you need

  • Stud finder
  • Drill + 6 mm bit (for drywall anchors) or 3 mm pilot bit (for studs)
  • Level (24" minimum)
  • Painter's tape
  • Pencil

Choose your mount

Into a stud — best. Holds 30+ kg per stud bracket. Studs are 16" or 24" apart.

Drywall anchors — for in-between locations. Use toggle bolts (snap-toggle or strap-toggle) for anything over 5 kg. Plastic expansion anchors are for picture frames only.

Install

  1. Mark your shelf height with painter's tape — it shows pencil lines and peels off cleanly.
  2. Check level — the floor in most Canadian houses is not level. Use the level, not the floor as reference.
  3. Find studs. Mark them.
  4. Hold the bracket against the wall. Mark hole locations through the bracket.
  5. Drill — pilot holes into studs, larger holes for anchors.
  6. Install brackets, then slide the shelf on.
  7. Re-check level. Adjust if needed before loading.

Reality check

  • Hollow-core IKEA shelves max out around 7 kg per bracket.
  • Solid wood shelves: 15 kg per stud bracket is realistic.
  • Books are surprisingly heavy — 30 cm of hardcovers ≈ 10 kg.
Editorial note. Wear appropriate PPE. When in doubt — especially with electrical, gas, or structural work — hire a licensed Canadian tradesperson. See our safety policy.
