Question: A carpenter is framing a rough opening for a 914 mm wide x 2032 mm high (36 in x 80 in) exterior door. Assuming standard clearances, what are the appropriate rough opening dimensions?
Answer options:
- 940 mm wide x 2057 mm high ✅ 965 mm wide x 2083 mm high
- 914 mm wide x 2032 mm high
- 991 mm wide x 2108 mm high
Correct answer: 965 mm wide x 2083 mm high
Explanation: For a door opening, generally an additional 51 mm (2 inches) is added to the width and 76 mm (3 inches) to the height of the door. So, 914 mm + 51 mm = 965 mm (width) and 2032 mm + 76 mm = 2108 mm (height). This allows for shimming and proper installation of the door frame. Therefore, 965 mm wide x 2083 mm high is the most common rough opening size, considering some slight variations for specific jamb sizes.
