How to Stack Firewood So It Actually Seasons

To stack firewood so it actually seasons, split the logs, set them on a base at least a few inches off the ground, leave air gaps, and cover only the top. A stack that is tight against the ground or wrapped in a tarp stays wet for months longer. This guide covers the base, the stacking pattern, stopping a stack from toppling, and how to check the wood before you burn it.

What a Firewood Stack Has to Do Before You Can Burn It

A stack is a drying rack, nothing more. Freshly cut wood holds a lot of water. According to the UNH Cooperative Extension, green wood runs between 50 and more than 100 percent moisture content, air-dried wood sits around 30 percent, and the best fuel is split, seasoned wood between 20 and 30 percent. Your job is to move the pile down that scale as quickly as the weather allows.

Wood type	Typical seasoning time (extension guidance)	What slows it down
Softwood such as pine or spruce	About 6 months	Wide, unsplit rounds dry slowly
Most hardwoods	About 12 months	Dense wood and large splits
Oak	Often up to 24 months	Very dense, tight grain

These are ranges, not promises. If you want species-level numbers, see our guides on how long oak takes to season and drying wood for burning by species. This page is about the stack itself, because the same oak dries on very different schedules depending on how it is piled.

Pick the Spot First: Sun, Wind, Drainage and Distance From the House

An open, sunny spot with good airflow on all sides is best, according to the UNH Cooperative Extension. Add three practical checks before you move a single log:

• Drainage: pick ground that does not pool water after rain, or build the base up with gravel.
• Wind: run the long side of the stack across the prevailing wind so air moves through the rows, not around them.
• Distance: keep the pile away from the house. Pest-control sources commonly advise at least three feet, and 20 to 30 feet in termite or wildfire-prone areas, because a woodpile against siding is a bridge for termites.
• Vegetation: trim back weeds and brush around the base. The same extension source notes that keeping wood off the ground and cutting back vegetation also discourages insects.

Get the Wood Off the Ground: Base Options Compared

Damp soil wicks moisture straight into the bottom layer. Any base that lifts the wood and lets air pass underneath fixes that. Here is how the common choices compare.

Base	Cost	Strength	Watch out for
Wood pallets	Often free	Fast to set up, built-in airflow	Sinks on soft ground; see the stamp note below
Two or more 2×4 or 4×4 skids	Low	Cheap and easy to level	Needs treated or rot-resistant lumber to last
Gravel pad plus skids	Medium	Best drainage, lasts years	More digging and hauling up front
Purpose-built log rack	Highest	Neat, sturdy ends	Capacity is limited; check the rated load

If you use pallets, check the stamp. Pallets marked HT were heat treated, while MB marks mean they were fumigated with methyl bromide and should not be burned. Our guide to heat-treated wood and pallet stamps explains the codes.

How Much Wood Fits on One Pallet? The Math

Most guides stop at “use a pallet” and never say how much it holds. A standard pallet is 48 by 40 inches. Stack 16-inch logs two rows deep and you use 32 inches of the 40-inch depth. At four feet tall, that is 48 x 32 x 48 inches, or about 42.7 cubic feet of stacked volume. A full cord is a 4 x 4 x 8 foot stack, which is 128 cubic feet, so one pallet holds roughly a third of a cord and you need about three pallets for a full cord. That also matches the size of a 4 x 8 foot face cord of 16-inch wood, covered in our guide to the measurements of a rick of firewood.

Stack footprint	Log length	Depth used	Height	Stacked volume	Share of a full cord
One pallet, 48 in long	16 in, 2 rows	32 in	48 in	42.7 cu ft	About 1/3
Three pallets in a row	16 in, 2 rows	32 in	48 in	128 cu ft	1 cord

Log length and gaps change the real number, so treat this as planning math, not a purchase guarantee. Stacked volume includes the air between logs, which is exactly the point.

Stacking Patterns That Dry Well

The pattern matters less than three rules: split wood, gaps for air, and a stable base. Choose the pattern that fits your space.

Single Row, Cut Faces Out

The simplest and fastest drying layout. Lay each course in the same direction, tight enough to stay put but not jammed. Because every log has two sides open to air, this is the pattern to use when you have the room.

Crosshatch Ends

Build each end as a small square tower, alternating the direction of every course like a log cabin corner, and fill the space between the towers with parallel rows. The crossed ends act as bookends that hold the rows in line.

Round Stack

A circular pile with the cut ends facing out and the center filled loosely. It looks good and sheds rain from a top covering, but the middle dries slowest, so it is a better choice for smaller amounts.

Step by step for a standard row:

1. Level the base: check it with a level so the whole row does not drift sideways.
2. Build the ends: crisscross two end towers about four feet apart.
3. Fill between them: lay split logs with the cut faces pointing outward, flat side down.
4. Mix sizes carefully: put the thicker splits low and the small pieces up top.
5. Cap the stack: lay a top covering, leaving the sides open.

How to Stop a Firewood Stack From Falling Over

A toppling stack can injure a child or a pet and it also scatters the wood back onto the wet ground. Most collapses have the same causes, and each has a simple fix.

• Soft or sloped base: pallets sink unevenly. Tamp gravel under them and level each one.
• Height: keep a freestanding single row to about four feet. Go taller only with braced, crisscrossed ends.
• Mixed shapes: long, curved or knotty pieces do not nest. Save them for the cores of crisscross ends or for kindling.
• No ends: a plain row has nothing holding its sides. Build crosshatch ends or use posts and stretch a rack frame between them.
• Climbing: never climb or lean on a stack. Remove wood from the top first, not from the bottom.

These height and spacing figures are common practice rather than a tested standard, so adjust to your ground. If a stack leans noticeably, restack it rather than propping it.

Covering the Stack: Top Only

The UNH Cooperative Extension says woodpiles can be left uncovered for maximum airflow or covered, but only on the top, because covering the top keeps rain out while air still circulates. A tarp pulled down all four sides does the opposite of what you want: it traps moisture rising from the wood, so the pile never gets to dry out.

• Use metal roofing, plywood, a purpose-made cover, or a tarp held a few inches above the logs.
• Let the covering overhang the stack by a few inches on the weather side.
• Weigh the cover down so it does not blow off or collapse onto the wood.
• If you have a woodshed, choose one with open or slatted sides.

Humid Climates and Large Stacks

Climate is one of the factors that sets drying time, and the MSU firewood guidance lists local climate, season of cutting and species as the main ones. In damp or humid regions, expect the long end of the ranges above and give the stack more room.

• Use single rows: in humid areas, deep piles hold moisture in the middle. A row one log deep dries fastest.
• Add space between rows: leave a gap of a few inches, more where the air is still and damp.
• Split smaller: narrower splits dry faster. Split rounds at least once.
• Time the work: cutting and stacking in spring gives a full summer of drying before the burning season.

For a very large amount of wood, build several single rows side by side on separate bases rather than one huge pile. The rows give you air on both sides and let you rotate the oldest wood to the front.

Check the Moisture Before You Burn

Weight, cracks on the ends and a hollow sound when two logs knock together are good hints. As the wood dries, it cracks open and becomes lighter, says UNH Extension, but a meter gives you a number. The correct method matters more than the brand:

1. Pick a log from the middle of the stack, not the outside.
2. Split it fresh and push the pins into the newly exposed face.
3. Run the pins parallel with the grain. The EPA recommends readings on newly split sides.
4. Take readings from three to five logs and average them, since seasoning is rarely uniform.

If the average reads about 20 percent or less, the stack is ready. If not, leave it another month and test again. Our guide to checking wood moisture without a meter covers backup tests. Unseasoned wood burns smoky and leaves more creosote in a chimney or stovepipe, which is a safety issue over a full heating season.

Common Firewood Stacking Mistakes

Mistake	What it causes	Fix
Stacking on bare ground	Wet bottom layer, pest access	Use pallets, skids or gravel
Wrapping the whole stack in a tarp	Trapped moisture, slow drying	Cover the top only
Burying the pile in shade	Little sun or wind	Move it to an open, sunny spot
Stacking unsplit rounds	Bark seals the wood	Split every round at least once
Stacking against the house	Termite bridge, fire load	Move it away from the structure

FAQ: Stacking Firewood

How far apart should rows of firewood be stacked?

Leave a gap of a few inches between rows so air can pass through the whole pile. Rows pressed back to back behave like one solid wall and dry slowly in the middle. A single row with its length facing the prevailing wind dries fastest, which is why long single rows beat deep piles.

Should firewood be stacked bark up or bark down?

There is no firm extension rule on this. What matters far more is that the stack is off the ground, split, and covered on top only. If you want a simple habit, set the top layer bark side up so the rounded bark sheds water outward, and do not spend extra time on the rest.

Can you stack firewood directly on the ground?

You can, but you should not. Bare soil keeps the bottom layer damp and gives insects an easy path into the pile. Even a few inches of clearance on pallets, skids or gravel helps. Pest-control sources commonly suggest keeping stacked wood at least six inches above the soil line.

How long does stacked firewood take to season?

Extension guidance puts it at roughly six months for softwood, about a year for most hardwoods, and up to two years for oak. Climate, species and split size change that. Test the wood with a meter rather than trusting the calendar, and burn it once it reads about 20 percent or less.

Is it okay to stack firewood against the house?

It is best not to. A pile against siding gives termites and other pests a bridge to the structure and can add fire load. Pest-control advice varies from at least three feet away up to 20 to 30 feet in higher-risk areas, so move the pile as far as is practical.
