• 7/8 inch (22 mm) – Often used for interior ceilings and walls.

• 1-1/2 inch (38 mm) – A standard size for heavier-duty applications.

• 2 inches (50 mm) – Used when greater coverage or strength is required.

2. Height (Depth / Leg Height)

• 7/8 inch (22 mm) – Most common size for furring out walls or ceilings.

• 1-1/2 inch (38 mm) – Offers more space for insulation and improved sound isolation.
