A sheet of 7/16 inch (approximately 11.1 millimeters) Oriented Strand Board (OSB) typically weighs around 45 to 50 pounds (20.4 to 22.7 kilograms). However, the exact weight can vary depending on the manufacturer, density of the board, and moisture content. If you need a precise weight for a specific project or purpose, it’s best to check the manufacturer’s specifications for that particular product.

Certainly, here are approximate weights for several common thicknesses of OSB panels. Please note that these are rough estimates, and actual weights may vary depending on the manufacturer, specific product line, and moisture content of the boards:

  1. 1/4 inch (about 6.4 mm) OSB: Roughly 20 to 25 pounds (9.1 to 11.3 kg) per sheet.
  2. 3/8 inch (about 9.5 mm) OSB: Around 25 to 30 pounds (11.3 to 13.6 kg) per sheet.
  3. 1/2 inch (about 12.7 mm) OSB: Approximately 35 to 40 pounds (15.9 to 18.1 kg) per sheet.
  4. 5/8 inch (about 15.9 mm) OSB: About 40 to 45 pounds (18.1 to 20.4 kg) per sheet.
  5. 3/4 inch (about 19 mm) OSB: As mentioned earlier, around 45 to 50 pounds (20.4 to 22.7 kg) per sheet.
  6. 1 inch (about 25.4 mm) OSB: Can reach upwards of 60 pounds (27.2 kg) or more per sheet.

For precise calculations in your project, it’s advisable to consult the official technical data sheets of the selected brand and product line for detailed information.
