There are a lot of numbers associated with firewood and I’ve tried to collect best estimates relevant to small woodlands, here in one place, along with enough context to use them. They’re not a substitute for what you actually see in your own circumstances, but they’re the kind of thing you need if you’re putting together a woodland management plan, prior notification for a drying barn, a business case, or even deciding roughly what you can do.

I’ve organised it in the same order as the firewood processing sequence: how much grows per year, what lengths to cut, when to split, how drying works, how much heat different species produce, loose vs stacked, and bag sizes.
