Which of the following is NOT a standard width for gypsum lath?

• A. 16 inches
• B. 24 inches
• C. 48 inches
• D. 36 inches

Answer: (D)

The concept here is knowing the standard widths gypsum lath is made in for plaster bases. Gypsum lath is stocked in widths that fit common framing and sheet sizes, which keeps installation efficient and minimizes waste. The standard widths you’d typically encounter are 16 inches, 24 inches, and 48 inches. The 48-inch width matches the common 4-foot sheet size, making long runs easier with fewer joints. The 16- and 24-inch widths align with typical stud spacing and easier handling for smaller or narrower runs. 36 inches isn’t a usual stock width, so using that width would require extra cuts and custom work, leading to more waste and labor.
