Stack firewood in a single row on a raised base, build both ends so they hold themselves up, and keep the pile under about four feet tall. Leave a gap between rows rather than gaps inside a row. Cap the top course bark side up.
The ends are what fail. Almost every collapsed woodpile came apart because someone stacked a tidy row and then just let the last pieces trail off into a heap at each end. The row has nothing to push against, the whole thing leans, and one frosty morning it’s on the ground.
This guide is about the build itself. Where to put the pile and how long the wood takes to dry are separate jobs, and we cover storing firewood outside and seasoning firewood on their own.
Why Woodpiles Fall Over
Three forces work against a stack, and knowing them makes every method below make sense.
Settling. Wood shrinks as it dries. A stack built tight in April is looser by September, and pieces that were locked in place start to roll.
Outward lean. Round splits want to become a cone. Every layer pushes the one below it sideways, and without something resisting that push at each end, the row spreads and drops.
Ground movement. Soft soil compresses unevenly under load. One end sinks half an inch, the stack tilts, and gravity does the rest.
Nothing here is fixed by stacking more carefully in the middle. It is fixed at the ends and at the base.
Five Ways to Stack Firewood
All five work. Pick by how much wood you have and what you already own.
Cribbed ends (no rack needed)
The traditional answer. You build a self-supporting tower at each end from pairs of splits laid at right angles, layer by layer, then fill the row between them. Costs nothing, works anywhere, and it’s the method we use for most of our wood.
Posts or steel stakes
Drive two T-posts or set two pairs of 4x4s at each end and stack between them. Faster than cribbing and it holds a taller row. The catch is that posts driven into soft ground lean outward over a season, so brace them or set them in gravel.
Lean-to along a wall or fence
Stack a single row with a slight backward tilt so it leans into a structure. Quick and stable, but it puts wood against something you probably want kept dry and pest-free, so read our storing firewood guide before choosing this one.
On a rack
A steel or timber rack solves the end problem entirely. Most consumer racks hold between a quarter and three quarters of a cord. Worth it if you burn a modest amount and want zero fuss; less economical once you’re storing multiple cords.
The Holzhausen (round stack)
A circular stack, roughly six to ten feet across, with the outer pieces laid radially and tilted slightly inward so the wall leans on itself. It holds a lot of wood in a small footprint and it looks superb. What it does not reliably do is dry wood faster, which we get to below.
How to Build a Cribbed End
This is the one skill worth learning, because it makes every other decision optional.
- Pick your flattest, squarest splits. Save a dozen while you work. Round pieces roll and will not lock. Species matters here: ash and hard maple break into flat, square faces that lock beautifully, while elm and sycamore give you stringy pieces that never sit still — how you split them decides how well they stack. Further our guide to types of firewood covers which species behave.
- Lay two pieces parallel, a split’s length apart, running into where the row will go.
- Lay the next two across them at right angles, sitting on the ends of the first pair. You now have a square.
- Repeat, alternating direction each layer, keeping the tower plumb or leaning very slightly inward toward the row.
Two details separate a crib that holds from one that spreads. Keep every layer level, checking by eye across the top rather than against the ground. And tilt the tower a degree or two toward the wood it’s holding, never away, because as the row settles it will push the crib outward and you want somewhere for that push to go.
Build both ends first, then fill the row between them. Building the row first and cribbing afterward almost never works.
How High Should You Stack?
Four feet. That is the practical ceiling for a free-standing stack, because a row narrow enough to dry well becomes too slender to stand much above it.
That figure is builders’ convention rather than an official standard, but it lines up with the places where the height is written down. Minneapolis, for instance, requires residential woodpiles to sit at least eight inches off the ground — check your own municipality, as figures vary. The same ordinance defines an acceptable stack as one that is stable and reasonably resistant to collapse.
That two-to-one ratio is the useful part. A stack 16 inches deep should not exceed about 32 inches tall unless it’s braced. A double-depth row, roughly 32 inches, can carry the full four feet comfortably.
When to stop and get help: if a stack over waist height has started to lean, do not try to push it back or pull pieces from the leaning face. Take it down from the top, working from the high side, or get a second person before you touch it. People are injured by collapsing woodpiles every year.
Bark Up or Bark Down?
Bark up on the top course. Below that it barely matters.
Purdue Extension, summarizing a review by the National Association of State Foresters, notes that when split wood is stored outdoors bark down, water can collect in the u-shaped trough, causing prolonged drying and accelerating decay. Under shelter the review found benefits and drawbacks to both, and treated it as personal preference.
So the rule is narrower than the internet suggests. A split lying bark-down in the middle of a covered row is not collecting anything. A split lying bark-down on the exposed top course is a small gutter, and it will stay wet.
The same Purdue summary makes a second point worth copying: laying small logs perpendicular underneath the stack improves airflow and reduces the chance of infestation. That’s a free upgrade if you’re short on pallets.
Does a Holzhausen Really Dry Wood Faster?
Probably not, and nobody has shown that it does.
The claim is everywhere: the round shape creates a chimney effect that pulls air through the middle. It sounds plausible. But no university extension service, forest products lab or published study has tested round-stack drying against a conventional row. The claim circulates on blogs and in retailer copy, repeated rather than measured.
The informal head-to-head tests that do exist point the other way. Woodburners who have built both and metered them report no advantage, and in some cases the round stack came out wetter, because the packed core is the one place air does not move.
Here is our position. Build a Holzhausen because it fits a lot of wood into a small circle, uses up short and odd-shaped pieces, and looks like something worth photographing. Do not build one expecting dry wood sooner.
Two practical warnings if you do. Keep the wall leaning inward the entire way up, because a wall that bulges outward as the wood settles is the standard failure, and it fails all at once. And plan on most of a day for a large one, against a few minutes per row for conventional stacking.
How Tight Should the Stack Be?
Tight within the row. Spaced between rows.
This trips people up because “leave gaps for airflow” gets repeated without saying where. Air moves through a woodpile along the row and between rows, not through the gaps you leave between neighboring pieces. Loose stacking inside a row buys you very little drying and costs you a lot of volume.
That volume matters if you buy or sell. The University of Wisconsin–Madison’s forestry extension is direct about it: a cord contains air space as well as solid wood and bark, and is therefore more of an indication of space occupied than actual wood measure, and their Lake States averages put a standard cord at 62% solid wood, 28% air and 10% bark. Stack the same wood loosely and that air fraction climbs while the wood you actually get stays the same.
Some states write the tightness into law. Maine’s rules for selling firewood define ranked and well stowed as pieces of wood placed in a row, with individual pieces touching and parallel to each other, and stacked in a compact manner.
The takeaway for a buyer: if a delivery arrives and the seller stacks it for you with visible daylight through the row, you are paying for air. For your own wood it costs you nothing but storage space, so stack it however you like.
Where Not to Stack
Between two living trees. It is the most tempting free option and the worst one. The stack abrades bark on both trunks, compacts the roots underneath, and the trees move independently in wind, so the row racks itself apart. You lose the woodpile and damage two trees.
On bare soft soil. This is a stability problem before it’s a moisture one. Loaded soil compresses unevenly, one end of the row sinks, and the whole stack tilts. A rigid base — rails, a rack, or a levelled gravel bed — keeps the row plumb through a wet winter.
Across a slope without terracing. Wood creeps downhill as it settles. Level a bench into the slope or step the stack in short sections, each with its own crib.
Tight against a wall. It blocks airflow on the face and hides whatever is happening behind the pile.
Frequently Asked Questions
A single row, on a raised base, with cribbed ends at both ends and around four feet of height. It costs nothing, dries well because both faces are exposed, and it stands up.
Around four feet free-standing. Keep height no more than twice the stack’s depth unless you brace it with posts. Some municipalities cap residential woodpiles at six feet.
Bark up on the exposed top course, so it sheds rain. Elsewhere in the pile it makes little practical difference.
There is no evidence that it does. It is space-efficient and attractive, and the packed center is the slowest part of the stack to dry.
Build cribbed ends from your squarest splits, alternating each layer at right angles, then fill the row between them. Two T-posts at each end work too.
No. You damage the bark and roots, and the trees sway independently and pull the stack apart.
Single dries better because both faces are open. Double is more stable and takes less ground, and it’s a fair trade once wood is already seasoned.
Pieces touching and parallel within the row, with a hand’s width or so between separate rows. Loose stacking inside the row wastes space without helping much.
The Short Version
Build the ends first. Keep it under four feet. Bark up on top, tight in the row, spaced between rows.
Do that and the stack you build in spring will be exactly where you left it when you need it, which is the entire point of stacking wood instead of piling it. Then it is just a matter of building a campfire worth the effort.
