Cords = Length (ft) × Height (ft) × Depth (ft) / 128 | Full Cord = 4' × 4' × 8' = 128 ft³
Frequently Asked Questions
How much is a cord of firewood?
A cord of seasoned hardwood typically costs $250-400 depending on region and wood type. Face cords (1/3 cord) typically cost $100-200. Prices are higher in urban areas and during winter. Green (unseasoned) wood is usually 20-30% cheaper.
What is the difference between a cord and a face cord?
A full cord is 4 ft × 4 ft × 8 ft = 128 cubic feet. A face cord (also called a rick) is 4 ft × 8 ft × 16 inches deep = about 43 cubic feet, or 1/3 of a full cord. Always clarify which measurement a seller is using.
What is the best firewood?
Best hardwoods by heat output (BTU per cord): Osage orange (32.9M), Hickory (27.7M), Oak (24-27M), Hard Maple (25.5M), Ash (23.6M). These produce long-lasting coals and less creosote. Avoid softwoods like pine for indoor heating as they create more creosote.
