A **cord of wood calculator** helps determine the **precise** amount of firewood in a stack or pile, using the standard measurement unit called a “cord.”

A cord represents a neatly stacked pile of wood measuring **128 cubic feet** (3.62 cubic meters), typically arranged in dimensions of **4 feet high, 8 feet long, and 4 feet deep**.

If you have a woodpile that measures **6 feet high, 12 feet long, and 4 feet deep**, the calculator would determine this equals **1.5 cords of wood** (288 cubic feet ÷ 128 cubic feet per cord = 1.5 cords).

## Cord of Wood Calculator

---|---|---|

4’×16’×4′ | 256 | 2.0 |

5’×12’×4′ | 240 | 1.875 |

6’×8’×4′ | 192 | 1.5 |

4’×20’×4′ | 320 | 2.5 |

3’×8’×4′ | 96 | 0.75 |

5’×10’×3′ | 150 | 1.17 |

6’×10’×2.5′ | 150 | 1.17 |

4’×12’×3.5′ | 168 | 1.31 |

2’×8’×8′ | 128 | 1.0 |

7’×6’×3.5′ | 147 | 1.15 |

8’×4’×4′ | 128 | 1.0 |

10’×4’×3.2′ | 128 | 1.0 |

12’×4’×2.67′ | 128 | 1.0 |

15’×2.5’×3.2′ | 120 | 0.94 |

9’×3.5’×4.5′ | 126.75 | 0.99 |

## Cord of Wood Calculation Formula

The formula for calculating cord volume is:

**Volume in Cords = (Height × Length × Width) ÷ 128**

Where:

**Height**is measured in feet**Length**is measured in feet**Width**is measured in feet**128**represents the cubic feet in one standard cord

For a stack measuring **5 feet high, 10 feet long, and 4 feet wide**:

`(5 × 10 × 4) ÷ 128 = 200 ÷ 128 = `**1.56 cords**.

## How to Calculate Cord of Wood?

To calculate a cord of wood, follow these steps:

**Measure the stack dimensions**:- Height (in feet)
- Length (in feet)
- Width (in feet)

**Multiply**these three measurements together to get cubic feet.**Divide**the result by**128**(cubic feet in a standard cord).

Stack dimensions: **4′ high × 16′ long × 4′ wide**

Calculate cubic feet: 4 × 16 × 4 = **256 cubic feet**

Convert to cords: 256 ÷ 128 = **2 cords**

## Is 4×8 a cord of wood?

A **4×8 measurement alone does not constitute a full cord of wood.** A **face cord** or **rick** typically measures **4 feet high by 8 feet long**, but the depth varies.

To be a full cord, the stack must also be **4 feet deep.**

`A `**4'×8' stack with a 16-inch depth** = 42.67 cubic feet

42.67 ÷ 128 = **0.33 cords** (approximately one-third of a full cord)

## Is a cord of wood 4x4x4?

No, a **4x4x4 stack equals 64 cubic feet**, which is only half a cord. A standard cord must be **128 cubic feet**, typically arranged as **4’×8’×4′.**

4’×4’×4′ =

64 cubic feet

64 ÷ 128 =0.5 cords

## How many 16-inch logs are in a cord?

Here’s a approximation:

- For
**6-inch diameter logs**: approximately**240 pieces** - For
**8-inch diameter logs**: approximately**180 pieces** - For
**12-inch diameter logs**: approximately**90 pieces**

The number of **16-inch logs in a cord** depends on the average diameter of the logs.

## Cord Volume Comparisons

Cord Amount | Cubic Feet | Typical Price Range (USD) |
---|---|---|

1/5 cord | 25.6 | $50 – $75 |

2 cords | 256 | $500 – $700 |

4 cords | 512 | $1,000 – $1,400 |

8 cords | 1,024 | $2,000 – $2,800 |

*Note: Prices vary significantly by region and wood type.*
