Brick identification on elevation: the 9 cm × 9 cm square face of a standard brick seen on the wall face is termed what in brick masonry?

Introduction / Context:
In brick masonry, names depend on which dimension of the brick is exposed on the wall face. Correctly identifying header and stretcher appearances is essential for interpreting bond patterns (English, Flemish) and for estimating and specifying work.

Given Data / Assumptions:

• Standard Indian modular brick nominal size ~ 19 × 9 × 9 cm (or conventional 9 × 4.5 × 3 in.).
• On the wall face, the exposed square face measures approximately 9 cm × 9 cm.
• Conventional brick terminology is used.

Concept / Approach:
When the shorter dimension (breadth) is presented on the face with the brick laid through the thickness, the visible square is the header face (about 9 × 9 cm). A stretcher shows the long rectangular face (about 19 × 9 cm). Terms like “front,” “side,” or “face” are non-technical descriptors and do not replace the masonry terms.

Step-by-Step Solution:
Identify the seen face: 9 cm × 9 cm square on elevation.Relate to brick orientation: short side shown → header.Therefore, the correct term is “Header.”

Verification / Alternative check:
Bond diagrams show alternating headers and stretchers; headers appear as 9 × 9 squares; stretchers as 19 × 9 rectangles.

Why Other Options Are Wrong:

• Stretcher: exposes the long face (≈ 19 × 9 cm), not square.
• Front/Side/Face: generic words; lack technical specificity.

Common Pitfalls:
Mixing up header and stretcher appearances; forgetting nominal size conventions.

Final Answer:
Header
