Not much beats gathering around the fire on a chilly evening. But to keep that fire burning bright and strong, you need the right amount of firewood. Too little, and you might find yourself shivering halfway through the night. Too much, and you’re left with a stack of wood that you might not have storage space for.


Figuring out exactly how much firewood you need doesn’t have to be a guessing game. The process is all about considering a few key factors, such as the size of the space you’re heating, how often you use your firewood, and even the kind of wood you’re burning. Let’s explore the best methods for determining how much firewood you need.


Measure the Space You Want to Heat

The size of your space directly determines how much firewood you need since larger areas require more heat energy to achieve comfortable temperatures. The way you’d measure differs slightly for indoor versus outdoor fires since there’s more open space outside.


Indoor Heating with a Fireplace

Indoor fireplace heating requires different calculations compared to other heating methods, as fireplaces are typically located in a specific room of the home, usually the family or living room. Normally, the standard fireplace burns four 16-inch logs every hour. That said, if you have a smaller room (100 to 250 sq. ft.), you may only need two logs; likewise, if you have a larger room (400+ sq. ft.), you may need five to six logs.


Outside Heating for Gatherings

Knowing how much wood you need to heat an outdoor space is a bit different since you’re in an open-air environment. The average standard fire pit with a medium-sized fire burns 3 to 4 logs per hour. However, if you have a smaller fire pit (less than 3 feet in diameter), you may only need 2-3 logs per hour. Conversely, for larger fire pits (over 4 feet in diameter) or if you’re aiming for a roaring fire, you might need 5-6 logs per hour.


Consider How Much You’ll Use It

Knowing how often you’ll use the wood also tells you how much you need to buy. If you only light a fire on Sunday nights after watching football with friends, you’ll need less wood than someone who lights a fire multiple times per week. The easiest way to calculate how much you need is to consider how many logs you use for each fire and how many days you light a fire per month. Add some buffer space to your calculation to ensure you have emergency wood for spontaneous bonfires or unexpected chilly nights.


Consider the Length of the Season

Most of us don’t light a fire during the dog days of summer since the natural heat is more than enough. However, once fall and winter roll around, the desire for a cozy fire becomes more appealing. Consider how long your fireplace season typically lasts and factor that into your wood storage calculations.


For example, in Brookhaven, GA, winters are typically mild with shorter heating seasons compared to colder northern climates. Residents might only need firewood from late November through February, meaning they’ll require less overall wood for their fireplaces or fire pits. Planning around this shorter season ensures you have enough firewood without overstocking.


Think About Burn Time Per Day

Daily burn time directly correlates with firewood consumption since longer fires require continuous fuel feeding. Calculating average burn hours per day during the heating season provides the foundation for accurate quantity estimates. Sustained burning operations consume wood at steady rates, making time-based calculations reliable.


A typical fireplace burns approximately six to eight pieces of split firewood per hour during active operation. Multiply hourly consumption by daily burn time and seasonal length to establish baseline requirements. Account for fire management techniques that affect consumption rates, such as damper control and log placement strategies.


Evaluate Storage Space

As you think about how much firewood you’ll order, you’ll also want to think about the size of your firewood rack, and where you’ll store the extra wood. Ideally, all firewood should be in a dry, sheltered area such as a woodshed, as it offers protection from rain while allowing air circulation. Alternatively, a partially covered spot can work as long as the wood is elevated off the ground and shielded from excess moisture. Storing naturally dried firewood in a bright sunny spot works as well, allowing sun and air flow to continue the seasoning process.


Proper storage helps prevent moisture from seeping into the wood, which can make it harder to burn and reduce heat output. Dry firewood ignites quickly, burns efficiently, and produces less smoke. By dedicating the right space for your firewood, you’ll ensure its quality and have an ample supply for your fireplace or fire pit year-round.


Tips for Buying Firewood

A woodshed sits outside beside a red brick wall; there are countless pieces of wood piled inside of the woodshed.

Knowing how to determine how much firewood you need is as important as buying the right wood. You’ll have to consider the type of wood, drying method, and who you buy from to ensure you get the best quality for your needs.


Assess the Type of Wood You’re Using

Wood type significantly affects burning efficiency, heat output, and consumption rates since different species contain varying energy densities. Some of the many types of wood used for fires include:


  • Oak: Burns hot and slow, making it ideal for long-lasting fires.

  • Hickory: Produces high heat and a nice aroma, great for both warmth and ambiance.


Evaluate Wood Drying Method

When buying wood, consider the drying method, as it directly affects how efficiently the wood burns, the heat it produces, and its clean burn. Most firewood companies sell seasoned and kiln-dried wood, and while both are great, your ideal choice comes down to personal preference.


Seasoned Wood

Seasoned wood is firewood that has been dried to reduce its moisture content, making it easier to burn efficiently. Properly seasoned wood typically dries for 6-12 months and produces more heat with less smoke compared to freshly cut, green wood.


Kiln-Dried Wood

Kiln-dried wood is machine-dried in days to reduce moisture below 20%, making it immediately usable. It burns cleaner and usually produces less smoke than seasoned wood, making it ideal for indoor use.
