Estimate how much firewood you need for a campfire based on burn time, fire size, wood type, group size, weather, and cooking use. This calculator can help plan camping trips, backyard fires, group campfires, and overnight campsite wood needs.
Burn time:
Enter how many hours you want the fire to burn. Longer fires need more logs, especially in cold or windy weather.
Fire size:
Small fires use less wood, while large group fires and bonfires use much more wood per hour.
Adjustments:
The calculator adjusts the estimate for wood type, group size, cooking use, weather, and extra reserve.
A campfire wood calculator helps estimate how many bundles, logs, or cubic feet of firewood to bring or buy for a camping trip, backyard fire, group campsite, or cooking fire.
Firewood use varies by log size, wood species, moisture, airflow, fire ring size, and how actively the fire is fed.
This calculator uses a practical firewood estimate:
Firewood Needed = hourly burn rate × burn time × adjustment factors + reserve
A typical evening campfire may use about 3 to 5 bundles, depending on fire size, burn time, wood type, weather, and how often you add logs.
One bundle often lasts around 1 to 2 hours for a small or moderate fire, but log size, wood type, moisture, and fire size can change that.
Hardwood usually burns longer and creates longer-lasting coals. Softwood often lights easier but can burn faster.
Yes. Bringing an extra reserve helps if the weather turns colder, wood is damp, the group stays up longer, or you need extra coals for cooking.
