Boards = area with allowance ÷ board area. Screws per board use a rectangular spacing grid; total screws and boxes are rounded up.

FAQ
Tile Backer Board Screw Calculator questions
Can ordinary drywall screws be used?+
Use fasteners approved for the selected backer board and exposure conditions.
Why can cut boards need more fasteners?+
Perimeter edges and small pieces can increase fastener density compared with a full-board grid.
Does this include seam tape?+
No. Joint reinforcement and mortar should be estimated separately according to the board system.
