How to Build a DIY Firewood Storage Rack

Firewood dumped on the lawn or stacked against the house dries slowly, rots from the bottom and invites insects close to your foundation. A simple rack fixes all of that with a few boards and an afternoon: it lifts wood off damp ground, keeps rows in neat stacks with air moving through them, and adds a small roof that sheds rain without trapping humidity. This design is an open-front, covered rack that’s easy to build and easy to extend.

Quick answer: Build a frame from pressure-treated 4x4 posts and 2x4 rails, with the bottom rails several inches off the ground. Keep it about 16–18 inches deep so one row of split wood fits, leave the front and ideally the ends open for airflow, and add a sloped roof with a small overhang. An 8 × 4 ft rack holds roughly a face cord (about a third of a full cord). Place it in sun and wind, a few feet from the house.

Project Overview

Detail	Estimate
Size (example)	8 ft long × 4 ft tall × 16–18 in deep
Capacity	About a face cord (roughly ⅓ of a full cord)
Difficulty	Beginner
Build time	4–6 hours (plus concrete curing if posts are set in the ground)
Main costs	Treated lumber, roofing panels, screws

Capacity at a Glance

A full cord is 4 × 4 × 8 feet, or 128 cubic feet. Racks are usually one row deep, so capacity depends on length and height.

Rack (L × H, 16 in deep)	Approximate volume	Roughly
4 × 4 ft	21 cu ft	Small porch supply
8 × 4 ft	43 cu ft	One face cord
8 × 6 ft	64 cu ft	Half a cord
16 × 4 ft	85 cu ft	Two face cords
24 × 4 ft (three sections)	128 cu ft	One full cord

What You’ll Need

Materials (8 × 4 ft rack)

• 4x4 pressure-treated posts rated for ground contact: 4–6
• 2x4 pressure-treated lumber for rails, cross pieces and rafters
• Roofing: corrugated metal or polycarbonate panels, or 1x6 boards covered with roll roofing
• Exterior screws (2½ and 3 in), a few structural screws or carriage bolts for main joints
• Roofing screws with rubber washers (for panels)
• Gravel, and concrete if setting posts in the ground
• Exterior stain or sealer (optional)

Tools

• Circular saw, drill/driver or impact driver
• Level, speed square, tape measure
• Post-hole digger (for in-ground posts)
• Clamps, eye protection, gloves

Step 1: Pick the Spot

Choose	Avoid
Sun and breeze to speed drying	Deep shade and still corners
Level, well-drained ground	Low spots where water pools
A few feet away from the house	Stacking against siding (insects and moisture)
Easy access from the door you use in winter	Long walks through snow
Away from fire pits and grills	Close to open flames

Step 2: Choose a Base

Option	Pros	Cons
Posts set in gravel or concrete	Very stable; permanent	More digging and curing time
Freestanding frame on a treated sill or pavers	Movable, no digging	Must sit on level ground; less wind-resistant when empty
Posts on concrete blocks or post bases	Keeps wood off soil	Needs careful leveling

For in-ground posts, dig holes about 18–24 inches deep (deeper where frost is severe), add gravel, set the posts plumb and fill with concrete or tamped gravel. Space posts no more than about 4 feet apart so rails and roof don’t sag.

Step 3: Build the Base and Rails

1. Attach bottom rails to the front and back of the posts, at least 4–6 inches above the ground.
2. Add cross pieces between the front and back bottom rails every 16–24 inches. They carry the weight of the wood, so use 2x4s on edge or doubled boards.
3. Attach top rails to the front and back, tying the posts together.
4. Add one or two horizontal rails on the back to keep logs from rolling out, leaving gaps for airflow.

Check the frame for square and level as you go.

Step 4: Add the Roof

• Make the back posts a few inches taller than the front (or cut rafters at an angle) so the roof slopes toward the front or back.
• Attach 2x4 rafters every 16–24 inches across the depth of the rack.
• Screw roofing panels to the rafters with washered roofing screws, or install boards and cover them with roll roofing.
• Let the roof overhang the front and sides by several inches to keep rain off the top rows.

Keep the sides open. A roof with open sides is what dries wood; enclosing the rack traps humidity.

Step 5: Finish and Load

Seal cut ends of treated lumber with an end-cut preservative or exterior sealer. Stack split wood loosely, bark side up on the top layer, with small gaps between pieces for air. Put the driest wood at one end or in front, and add newly split wood behind it so you burn the oldest wood first. Leave a little space between the top of the stack and the roof.

Extending the Rack

Add sections end to end, sharing a post between sections. One long rack uses less lumber than several separate ones. Many people build one section for wood that’s ready to burn and a second for next year’s wood that’s still drying.

Troubleshooting

Problem	Likely cause	Fix
Rack leans or racks sideways	Posts not set deeply, no bracing	Add diagonal braces at the ends; reset posts
Base rails sagging	Cross pieces too far apart	Add supports every 16 in
Top rows wet after storms	Roof too short or flat	Extend the overhang; increase slope
Wood still damp after a season	Shade, tight stacking, green wood	Move to sun; stack loosely; split smaller
Insects in the stack	Wood near the house or on soil	Keep the rack off the ground and away from the foundation

FAQ

How far should a firewood rack be from the house?

A few feet at minimum, and farther for the main supply. Bring small amounts to the door as needed. This limits moisture and insects near your walls.

Should a firewood rack be covered?

Cover the top only. The sides should stay open so air moves through the stack.

How much wood does a rack hold?

An 8-foot-long, 4-foot-high, single-row rack holds about a face cord. Three of those sections together hold about a full cord.

Can I use untreated lumber?

For parts that touch the ground or stay damp, use treated lumber rated for ground contact. Untreated wood rots quickly under a woodpile.
