How are window sizes designated or called out in architectural plans?

Window sizes in architectural plans are designated as width by height. This convention is used universally across the construction industry, making it clear and consistent for all professionals involved in the design and building process.

When measuring a window, the width is measured first, which refers to how wide the window is from one side to the other. Following this measurement, the height is described, indicating how tall the window is from the bottom to the top. This method of designation allows for easier understanding and implementation, as contractors and builders can quickly visualize the dimensions of the window as they are represented in the design documents.

Additionally, this standard reinforces the general practice often used in construction that dimensions are listed in the order of horizontal followed by vertical measurements, maintaining uniformity across various elements in building plans.
