In window specifications, the first dimension given for glass refers to what measurement?

In window specifications, the first dimension given for glass typically refers to the width. This common practice aligns with how measurements are recorded in the construction and manufacturing industry, where width is prioritized as the first dimension. For instance, when specifying a window that is 24 inches by 36 inches, it means the window is 24 inches wide and 36 inches high. Understanding this standard is crucial for proper ordering and installation, ensuring that the windows will fit correctly into their designated spaces. This emphasis on the width as the first dimension aids builders and contractors in visualizing the product and planning the overall design accurately.
