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)

### 📊 Units Cheat Sheet

Measurement | Imperial | Metric |
---|---|---|

Weight | Pounds (lbs) | Kilograms (kg) |

Length | Feet (ft) | Meters (m) |

Width | Feet (ft) | Meters (m) |

Thickness | Inches (in) | Millimeters (mm) |

Density | lbs/ft³ | 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.
