Wall Load per meter = Thickness × Height × Unit Weight + Finish Load

A 230 mm wall, 3 m high at 20 kN/m³ gives 13.8 kN/m masonry load before finishes.

For structural, electrical, code-compliance or safety-critical work, use this as a preliminary estimate and verify with a qualified professional.

Short answers for common estimation questions.

No. These pages provide preliminary self-weight or dead-load estimates only.

A qualified structural engineer should verify design loads, combinations and code requirements.
