Firewood Cord & Stack Calculator
Measure actual usable stack space, see the equivalent stacked cubic feet and cord quantity, then record the route from delivery point to stack.
How many cords are in your stack? Multiply length (feet) × height (feet) × depth (inches ÷ 12), then divide by 128. Measure compactly stacked wood; empty rack dimensions estimate capacity.
This shares the calculator link. Use ‘Share’ beside your result to include your measurements.
Our standard ¼ cord is 32 stacked cubic feet: 8 feet long × 3 feet of actual wood height × 16 inches deep, or two 4-foot-wide stacks of that height and depth. Measure the wood itself; a rack’s advertised dimensions do not establish its contents.
Example measurements — replace the starter values and review every measurement and assumption.
Where to measure the rack
Measure only the space you will actually stack. A rack’s advertised size may include legs and end frames.
Stack dimensions
Measure usable space
Use the space the wood can actually occupy — not the rack's outside dimensions.
For one row of 16-inch pieces, enter about 16 inches. For two parallel rows, enter their actual combined depth.
Delivery & stacking access
A careful estimate is more useful than pretending this is exact.

Access result
Trailer access needs confirmation
Safe photographs from well away from hazards, ordinary clearance measurements, and an unloading or turnaround plan are needed before a trailer delivery is assumed.
Normal-access stacking is included within 25 feet on a clear, level route. Longer carries, steps, hills or soft ground require a separate quote. A gate under 120 inches, uncertain trailer entry or turnaround, overhead concern, or roadway backing triggers confirmation. Actual vehicle dimensions and field conditions govern.
Copy, print, and share run only when you choose them. Sharing sends this summary to the app or person you select.

Common firewood stack examples
Each example is 8 feet long and 3 feet of actual wood height. Depth is the total across all rows. One cord is 128 compactly stacked cubic feet.
| Total depth | Stacked cubic feet | Cord quantity |
|---|---|---|
| 16 inches | 32 | ¼ cord |
| 32 inches | 64 | ½ cord |
| 48 inches | 96 | ¾ cord |
| 64 inches | 128 | 1 cord |
Can I calculate a cord from a loose pile or truck bed?
This calculator uses compact-stack dimensions. Loose pieces leave different-sized gaps, so truck-bed or loose-pile volume does not establish the stacked cord quantity. Stack and measure the wood, or ask the seller to confirm the measured quantity.
How do I measure more than one row?
Enter the total actual depth across the rows. Two rows of 16-inch logs would be about 32 inches deep if they fit closely together. Use the number-of-stacks field only for separate stacks with the same dimensions.
