Plywood Weight Calculator – How much does a plywood sheet weigh

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 lbs

📏 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

1. Measure your plywood (L × W × T)
2. Convert all units to be consistent
3. Look up the density for your plywood type
4. Plug everything into the formula
5. 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:

1. Span: The distance between support points
2. Load type: Uniform or point load
3. Wood grade: Higher grades generally have better strength properties
4. 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.
