Spacing (horizontal × vertical)
Check against (masonry veneer)

Each anchor covers horizontal × vertical spacing of wall. The code check is for anchored masonry veneer — other cladding may follow its maker's spacing.

Extra anchors at openings▾

Masonry veneer: openings over 16" need anchors within 12" of the edge, max 36" apart. Enter the total perimeter of those openings.

  1. Wall area per anchor
    horizontal × vertical spacing (in) ÷ 144
    16 × 16 (in) ÷ 144 = 1.778
  2. Anchors per SF
    1 ÷ SF per anchor = 144 ÷ (h × v)
    144 ÷ (16 × 16) = 0.5625
  3. Anchors on the wall
    wall SF × anchors per SF, rounded up
    1,000 SF × 0.5625 = 563

Where the numbers come from

  • Anchors per SF: One anchor per horizontal × vertical spacing of wall; 144 in² = 1 SFPure geometry: 16" × 16" = 256 in² = 1.78 SF per anchor = 0.5625 anchors per SF; 16" × 24" = 2.67 SF = 0.375 per SF. The count is wall SF × anchors per SF, rounded up — it does not add a row at the wall's edges.
  • Masonry veneer limits: Adjustable, W1.7 wire or 22 ga corrugated: max 2.67 SF of wall per anchor; other types 3.5 SF; max 32" horizontal × 25" verticalTMS 402-13 (Building Code Requirements for Masonry Structures) as summarized by the Mason Contractors Association of America, for wind up to 40 psf. Wind 40–55 psf: 70% of those areas and 18" max spacing; Seismic Design Category D and up: 75% of the area. Your local code and the anchor maker can be stricter. Stone cladding and other systems may follow their maker's spacing instead.Source
  • Around openings: Openings over 16" either way: extra anchors within 12" of the opening, max 36" apart (24" in high wind)The page counts them from the total opening perimeter ÷ spacing, rounded up once for all openings (per opening it can be one or two more).Source

How many anchors or ties a wall needs: wall SF × anchors per SF, from the horizontal and vertical spacing. Works for brick veneer, stone cladding or anything set on an anchor grid.
