What does "stretcher" refer to in bricklaying?

In bricklaying, the term "stretcher" specifically refers to a brick laid with its long side facing the wall. This orientation is crucial in brickwork because it maximizes the contact area of the brick with the mortar, providing greater stability and strength to the wall as a whole. By laying the brick this way, it helps in creating a bond that can effectively distribute the weight and stresses applied to the wall.

The use of stretchers is a fundamental aspect of various brick patterns, which influence not just the wall's strength but also its appearance. When stretchers are used consistently, they create a visually appealing façade that is common in many brick constructions.

The other options describe different configurations or types of bricks that do not align with the definition of a stretcher. For instance, a brick laid with its narrow side facing the wall is known as a "header," while a horizontal brick layer refers to the positioning rather than a specific type, and a decoration type does not pertain to the functionality of bricklaying techniques. Understanding this terminology is critical for effective communication and execution in bricklaying practices.
