4. 48x60, 60x72, and 72x84 inches

The correct answer is: 24x36, 36x48, and 48x72 inches

The standard sizes of glass sheets used in residential windows typically align with the most common window sizes for ease of installation and replacement. The dimensions of 24x36, 36x48, and 48x72 inches are frequently used because they represent a range of sizes that meet the needs of various residential applications. These sizes allow for versatile installation options, accommodating different styles and types of windows such as casement, double-hung, and sliding windows. Additionally, manufacturers commonly produce glass sheets in these dimensions, which ensures they are readily available for contractors and glaziers. The inclusion of larger dimensions, like 48x72 inches, reflects the trend in modern architecture towards larger windows, which are popular for maximizing natural light and aesthetic appeal in residential spaces. Understanding these common sizes is crucial for those in the glazier profession as it assists in estimating material needs and planning for installations effectively. Other options include sizes that may be used in specialized applications or other types of constructions but are not as commonly implemented in standard residential window frameworks, which contributes to their exclusion from the most standard sizing by glaziers.
