Plywood Weight Calculator
Use plywood weight calculator to determine the mass of plywood sheets based on their dimensions, thickness, density, and moisture content.
When you’re planning to transport 20 sheets of plywood for a construction project, you can use the calculator to determine if your vehicle can safely handle the load. Simply input the dimensions (like 4×8 feet) and thickness (say 3/4 inch), and the calculator will provide the total weight.
Plywood Weight Formula
The formula for calculating plywood weight is:
Weight = Length (ft) × Width (ft) × Thickness (in) × Density (lb/ft³)For imperial measurements:
Weight (lbs) = Length (ft) × Width (ft) × Thickness (inches) × Density (lb/ft³) × 1/12The factor 1/12 converts thickness from inches to feet
For metric measurements:
Weight (kg) = Length (m) × Width (m) × Thickness (m) × Density (kg/m³)Standard 3/4″ Construction Grade Plywood:
- Dimensions: 4ft × 8ft × 0.75 inches
- Density: 34 lb/ft³
- Weight = 4 × 8 × 0.75 × 34 × (1/12)
- Result: 68 pounds
Marine Grade 1/2″ Plywood:
- Dimensions: 4ft × 8ft × 0.5 inches
- Density: 36 lb/ft³
- Weight = 4 × 8 × 0.5 × 36 × (1/12)
- Result: 48 pounds

How to Calculate How Much Does a Sheet of Plywood Weigh
To accurately calculate plywood weight, follow these steps:
- Measure dimensions precisely using appropriate tools
- Identify the plywood grade and corresponding density
- Convert all measurements to compatible units
- Apply the weight formula
- Account for moisture content (add 8-12% for exterior grade)
How much does a 4×8 sheet of plywood weigh
A standard 4×8 sheet of plywood varies in weight based on thickness:
- 1/4 inch: 22-25 pounds
- 1/2 inch: 45-50 pounds
- 3/4 inch: 65-70 pounds
- 1 inch: 85-90 pounds
A 1/2-inch thick half sheet (4×4 feet) typically weighs between 22-25 pounds, making it more manageable for solo handling. The exact weight depends on:
- Wood species used
- Number of plies
- Manufacturing process
- Moisture content
What is Plywood Weight?
Plywood weight refers to the measured mass of engineered wood panels created by layering multiple thin sheets (plies) of wood veneer bonded together with specialized adhesives.
Hardwoods (oak, maple, birch) create denser, heavier panels
Softwoods (pine, fir) result in lighter sheets
