A plywood weight calculator is a tool used to estimate the weight of plywood sheets based on their dimensions and type.
For a standard 4′ x 8′ sheet of 3/4″ softwood plywood:
Area: 32 square feet
Average Weight per Square Foot: Approximately 2.3 pounds
Total Weight:
Formula: Total Weight = Area × Average Weight per Square Foot
Calculation: Total Weight = 32 sq ft × 2.3 lbs/sq ft ≈ 73.6 lbsPlywood Weight Calculator

📏 Plywood Weight Formula
Weight = Length × Width × Thickness × Density🌲 Plywood Densities
- 🌱 Softwood: 34-42 lbs/ft³ (545-673 kg/m³)
- 🍁 Hardwood: 43-50 lbs/ft³ (689-801 kg/m³)

🔢 Step-by-Step Calculation
- Measure your plywood (L × W × T)
- Convert all units to be consistent
- Look up the density for your plywood type
- Plug everything into the formula
- Calculate!
Example 1: Imperial Units
- Sheet size: 4′ × 8′ × 3/4″
- Softwood plywood (38 lbs/ft³)
- Convert thickness: 3/4″ = 0.0625 ft
- Calculate: 4 × 8 × 0.0625 × 38 = 76 lbs
Example 2: Metric Units
- Sheet size: 2.4m × 1.2m × 18mm
- Hardwood plywood (750 kg/m³)
- Convert thickness: 18mm = 0.018m
- Calculate: 2.4 × 1.2 × 0.018 × 750 = 38.88 kg
How Much Does a 4×8 Sheet of Plywood Weigh?
Common plywood thicknesses include 1/4″, 3/8″, 1/2″, and 3/4″. Here’s a general range:
- 1/4″ thick: 20-25 lbs
- 3/8″ thick: 30-35 lbs
- 1/2″ thick: 40-45 lbs
- 3/4″ thick: 60-70 lbs
The weight of a 4×8 sheet of plywood varies depending on its thickness and wood type.
How Much Weight Can a 1/2 Sheet of Plywood Hold?
The weight-bearing capacity of a 1/2″ sheet of plywood depends on several factors:
- Span: The distance between support points
- Load type: Uniform or point load
- Wood grade: Higher grades generally have better strength properties
- Support configuration: Edge support vs. center support
Weight of 18mm Plywood Sheet in kg
Its weight can vary based on the wood type and exact dimensions. For a standard 4×8 foot (1220×2440 mm) sheet:
- Softwood plywood: Approximately 28-32 kg
- Hardwood plywood: Approximately 32-36 kg
What is the Weight of 8×4 Ply?
- 6mm (1/4″): 20-25 kg
- 9mm (3/8″): 30-35 kg
- 12mm (1/2″): 40-45 kg
- 18mm (3/4″): 60-70 kg
The term “8×4 ply” typically refers to a standard plywood sheet measuring 8 feet by 4 feet (2440×1220 mm). The weight of this sheet depends on its thickness and wood type.
