Campfire Wood Calculator
Estimate how much firewood you need for an evening campfire from burn time and fire size.
How it works
logs = logs-per-hour (by size) × hours × nights · bundles = logs ÷ 6
A steady campfire consumes wood at a fairly predictable rate: a modest evening fire burns roughly 5 split logs per hour, a small cooking fire fewer, and a large group fire more. Multiplying that rate by your hours per night and number of nights gives a total, which converts to store bundles at about 6 logs each. Buy a little extra for slow-starting damp wood, and remember many campgrounds require locally sourced or certified wood to avoid spreading pests.
Worked example
A medium fire (5 logs/hr) for 4 hours a night over 2 nights needs 5 × 4 × 2 = 40 logs, about 5 cu ft or roughly 6.7 bundles.
Frequently asked questions
How much wood does a campfire use per hour?
A typical evening fire burns about 4–6 split logs per hour once established. Cooking fires use less; large social fires can use 8 or more.
How many logs are in a bundle?
Store bundles vary but commonly hold about 5–7 split logs, roughly 0.75 cubic foot. This tool assumes 6 logs per bundle.
Can I bring my own firewood?
Often not — many parks require firewood bought locally or certified heat-treated to prevent spreading invasive insects. Check the campground’s rules before hauling wood in.
