How to Measure Firewood: Cord, Rack, and Local Buying Rules

by Travis Erbe

Buying firewood should not mean guessing how much wood will arrive. A cord describes stacked volume; a rack describes a container or stack whose dimensions can vary. Here is how to compare quantities and choose your JMS Firewood order.

How much wood is a cord?

A full cord is 128 cubic feet of stacked firewood. A stack 4 feet high × 4 feet deep × 8 feet long measures 128 cubic feet: 4 × 4 × 8 = 128. This is stacked volume, including the spaces between pieces, not 128 cubic feet of solid wood.

To measure a rectangular stack, multiply height × length × depth, with every measurement in feet. Divide the result by 128 to calculate the fraction of a cord. Measure a neatly stacked load rather than estimating from a loose pile or truck bed.

Why a rack is not automatically a cord

A rack's front dimensions do not tell you its volume without the depth. For example, a stack 4 feet high × 8 feet long with a depth of 16 inches measures about 42.7 cubic feet, or one-third of a cord. The same height and length with a different depth produces a different quantity.

Names such as rack, rick, and face cord can mean different things to different sellers. Ask for all three dimensions and the stated cord fraction before comparing prices. A truckload alone does not tell you the stacked volume.

How JMS labels its common stack sizes

Both our Kiln-Dried Mixed Firewood and Kiln-Dried All Oak Firewood currently offer these size labels:

  • 2 × 4 ft: 1/12 cord, about 10.7 cubic feet.
  • 4 × 4 ft: 1/6 cord, about 21.3 cubic feet.
  • 4 × 6 ft: 1/4 cord, 32 cubic feet.
  • 4 × 8 ft: 1/3 cord, about 42.7 cubic feet.
  • 4 × 12 ft: 1/2 cord, 64 cubic feet.

These two-dimensional labels pair a stack size with a stated cord fraction. They are consistent with a stack depth of approximately 16 inches; the front dimensions alone do not establish volume. Confirm piece length and stacking arrangements with JMS if you are fitting an existing rack. Each size offers Yes Stack and No Stack options.

Why measurement language matters in Virginia

Clear quantity descriptions help you compare offers and resolve questions about a delivery. For a Virginia purchase, ask the seller to put the quantity, measurement basis, price, and contact details in writing. Keep your order confirmation or receipt and measure the stack if the delivered quantity is in question.

This guide explains measurement, not the legal acceptability of any seller's terminology. For current Virginia firewood sales and measurement requirements, consult the Virginia Department of Agriculture and Consumer Services (VDACS), Weights and Measures program. Do not assume that an informal term such as rack or truckload establishes a recognized sales unit.

Choose the right wood for your needs

Kiln-Dried Mixed Firewood is our kiln-dried option for everyday firewood needs, with optional stacking. The product page describes it as ready to burn on delivery.

Kiln-Dried All Oak Firewood is an all-oak option for buyers seeking easy lighting and a slow burn, including fireplace and wood-fired pizza oven use. Check the product page for current ordering and delivery details.

Local sourcing and responsible buying

Ask where your firewood originated and buy close to where you plan to burn it when possible. Moving firewood can move insects and plant diseases, so check destination rules before taking wood to a campground or across regional boundaries. Do not assume that a kiln-dried label alone satisfies every destination's treatment or transport requirements.

Responsible buying combines a clearly measured quantity, wood suited to your appliance, and attention to its origin and destination. Ask JMS about sourcing and any documentation you need before transporting an order.

A quick checklist before ordering

  • Choose the cord fraction you need, not just a rack name.
  • Confirm stack dimensions and piece length.
  • Select stacking if you want help placing the delivery.
  • Keep the written quantity and price details.
  • Check local or campground rules before moving firewood.
