How the Firewood Cord Calculator Formula Works
A cord of firewood is a stack 4 feet high, 4 feet deep and 8 feet long: 4 × 4 × 8 = 128 cubic feet. Measure your stack's length, height and depth, multiply them to get its volume in cubic feet and divide by 128 to get the number of cords.
A face cord is the 4 by 8 foot face of a stack that is only one log deep. The calculator reports face cords as the stack's face area divided by 32 square feet, which is how many 4 by 8 foot faces it contains. Because the depth of a face cord equals the log length, its volume differs from the true cord, and 16 inch logs make a face cord of one third of a cord.
If you enter a price per cord, the cost is the number of cords times the price. In planner mode you give a number of cords, a height and a depth, and the calculator finds the stack length you need. Measurements can be entered in feet, inches, metres or centimetres.
cords = (length × height × depth) / 128 cubic feet; face cords = (length × height) / 32 sq ft; cost = cords × price per cord- lengthft, in, m or cm96Length of the stack along the ground.

A Real Worked Example
A load is delivered as one stack that is 96 inches long, 48 inches high and 16 inches deep, because the logs are cut to 16 inches. The volume is 96 × 48 × 16 = 73,728 cubic inches, which is 42.67 cubic feet.
Divided by 128 cubic feet, that is 1/3 of a cord. The face area is 8 by 4 feet, so it counts as exactly one face cord. At $250 per cord the load is worth $83.33, which is a useful check on what you were charged.
A full cord: 8 x 4 x 4 feet
Switch the unit to feet. 8 × 4 × 4 = 128 cubic feet, exactly one cord, or 3.62 cubic metres. The 4 by 8 foot face is one face cord, but because the stack is 4 feet deep it is also a complete cord.
This is the stack the measure is named for.
A stack 12 ft long, 5 ft high and 2 ft deep
12 × 5 × 2 = 120 cubic feet, or 120 / 128 = 0.9375 of a cord. The face is 60 square feet, which is 1.875 face cords of 4 by 8 feet.
At $300 per cord, the wood is worth $281.25. It is just under a full cord, which the face measure alone would overstate.
Planning 3 cords at 4 ft high and 16 in deep
Choose the planner mode and enter 3 cords, a height of 48 inches and a depth of 16 inches. Three cords is 384 cubic feet. Divided by the cross-section of the stack (48 × 16 inches) the stack must be 864 inches long, or 72 feet.
That is also nine face cords of 16 inch logs. If 72 feet of space is too much, raise the stack higher or split it into two rows.
Metric: a stack 3 m long, 1.2 m high and 0.4 m deep
Choose metres. 3 × 1.2 × 0.4 = 1.44 cubic metres, which is 50.85 cubic feet, or 0.3973 of a cord.
The 3 by 1.2 metre face is 38.75 square feet, so 1.21 face cords of 4 by 8 feet.
What Else to Know
What a Cord of Firewood Is
A cord is a volume, not a weight or a count of logs. It is the amount of stacked wood that fills a space 4 feet high, 4 feet deep and 8 feet long, which is 128 cubic feet or about 3.62 cubic metres. The measure includes the air gaps between the logs, so it is a measure of the stack rather than of solid wood.

Because a cord is only a volume, it can take any shape. A stack 16 feet long, 4 feet high and 2 feet deep is also a cord. What counts is the stack's length times its height times its depth equalling 128 cubic feet.
The calculator converts the three measurements into cords, cubic feet and cubic metres. It also reports face cords, and it can price the stack if you give it the cost of a full cord.
Calculating Cords From Your Stack
Stack the wood tightly and measure the length of the row, the height of the stack and the depth. For a single row of logs, the depth is the log length. Multiply the three measurements in feet to get cubic feet, then divide by 128.

A stack 96 inches long, 48 inches high and 16 inches deep is 8 by 4 by 1.33 feet, or 42.67 cubic feet, a third of a cord. A stack 12 feet long, 5 feet high and 2 feet deep is 120 cubic feet, which is 0.9375 of a cord, close to full but not quite.
If the stack is uneven, measure the height at the lowest and highest points and use the average. A loose or tumbled pile overstates the volume, so stack it before measuring.
Face Cords, Ricks and Fireplace Cords
A face cord is a stack 4 feet high and 8 feet long that is one log deep. It is also sold as a rick or a fireplace cord. The 4 by 8 foot face is the same as a cord's face, but the depth is the log length, not 4 feet, so a face cord is only a fraction of a cord.

Its volume is the log length in feet times 32 cubic feet. With 16 inch logs it is 42.67 cubic feet, one third of a cord. With 12 inch logs it is a quarter, and with 24 inch logs it is a half. The names and meanings of these terms are not uniform, so when you buy by the face cord, ask for the log length and the stack dimensions.
The calculator reports face cords as the stack's face area divided by 32 square feet, which tells you how many 4 by 8 foot faces it has, and separately reports the true cord.
Comparing Prices and Checking a Delivery
To compare offers, convert each to a price per full cord. Divide the price by the number of cords delivered, where cords equals the stack's cubic feet divided by 128. A face cord of 16 inch logs sold for $90 is about $270 per cord.

When wood arrives, stack it tightly and measure it. A load you were quoted as a cord should measure close to 128 cubic feet, or 3.62 cubic metres. If it is well under, you can use the calculator to find the fraction you actually received and the price per cord you paid.
Prices differ by region, species and dryness, so no single cost per cord is given here. Enter the quote you have and the calculator multiplies.
Planning a Stack or Woodshed
In planner mode you enter the number of cords you want to store, the height you will stack to and the depth, which is the log length. The calculator returns the stack length you need.

Three cords is 384 cubic feet. A stack 4 feet high and 16 inches deep needs 72 feet of length to hold it, which is why people stack in several rows or build the pile higher. Keep stacks stable: very tall single rows can topple, so a stack is usually kept to about the height you can reach and cross-stacked at the ends.
Leave space around the pile for airflow, because wood dries from the exposed faces. The calculator measures only the stack's volume. It does not size a shed roof or a foundation.
Metric and Other Units
Outside the US, firewood is commonly measured in cubic metres of stacked wood. One cubic metre is 35.31 cubic feet, so a cord is about 3.62 cubic metres, and a cubic metre is about 0.276 of a cord.

The calculator accepts feet, inches, metres and centimetres. Choose the unit once and enter every dimension in it. A stack 3 metres long, 1.2 metres high and 0.4 metres deep is 1.44 cubic metres, which is 0.3973 of a cord.
Volume is what the cord measures, so weight, species, moisture and heat value are separate questions that this calculator does not answer.

Frequently Asked Questions About the Firewood Cord Calculator
How big is a cord of wood?
A full cord of firewood is a stack 4 feet high, 4 feet deep and 8 feet long, which is 128 cubic feet or about 3.62 cubic metres. That volume includes the gaps between the logs. Any stack of the same total volume counts as a cord, whatever its shape.
How do you calculate a cord of wood?
Multiply the stack's length, height and depth in feet to get cubic feet, then divide by 128. A stack 12 feet long, 5 feet high and 2 feet deep is 120 cubic feet, or 0.9375 of a cord. The calculator does the same sum in feet, inches, metres or centimetres.
How many cubic feet are in a cord of wood?
A cord contains 128 cubic feet of stacked wood, including the air space between the pieces. In metric terms that is about 3.62 cubic metres. The actual solid wood is less, since the gaps are part of the 128 cubic feet, so the measure describes the stack's volume, not the wood alone.
What is a face cord?
A face cord, also called a rick or a fireplace cord, is a stack 4 feet high and 8 feet long that is one log deep. Its volume depends on the log length: 16 inch logs give 42.67 cubic feet, one third of a cord. The term is not defined the same way everywhere, so ask a seller for the log length.
How many face cords are in a cord?
It depends on the log length. A stack of 16 inch logs, 4 by 8 feet on the face, is 1/3 of a cord, so three face cords make a cord. For 12 inch logs it is 1/4, so four. For 24 inch logs it is 1/2, so two. Always confirm the log length when you buy by face cord.
How much is a face cord of wood?
A face cord is a stack 4 feet high and 8 feet long, with a depth equal to the log length. Its volume is the log length in feet times 32 cubic feet, so 16 inch logs give 42.67 cubic feet, about 1/3 of a cord. Enter the log length in the calculator for the exact fraction.
How many cords are in a pickup truck load?
That depends on the truck bed and how high the wood is piled. A bed measuring 8 by 4 feet and filled 1 foot deep holds 32 cubic feet, or 1/4 cord. Measure the stacked length, height and depth of the actual load and enter them into the calculator for the exact fraction of a cord.
How much wood is in a half cord?
A half cord is 64 cubic feet, such as a stack 8 feet long, 4 feet high and 2 feet deep. The same volume is a stack of 24 inch logs 8 feet long and 4 feet high. It is about 1.81 cubic metres.
How much wood is in a quarter cord?
A quarter cord is 32 cubic feet, equal to a stack 8 feet long, 4 feet high and 1 foot deep. That fits 12 inch logs in a stack 8 feet by 4 feet. In metric terms it is about 0.91 cubic metres.
How do I measure a stack of firewood?
Stack the wood tightly in a neat row, and measure the length along the row, the height at the shortest and tallest points and the depth, which is the log length. Enter the three numbers and the calculator returns cords and face cords. A loose, uneven pile overstates the volume.
How much does a cord of wood cost?
Prices vary by region, wood species, how dry it is and whether it is delivered. Enter the price you were quoted for a full cord and the calculator multiplies it by the cords in your stack, so you can compare a half cord or a truck load at the same price per cord.
How do I compare firewood prices?
Convert each offer to price per full cord. Divide the price by the number of cords in the amount offered, which is its volume in cubic feet divided by 128. A $90 face cord of 16 inch logs is about $270 per cord, and the calculator does this sum for you.
How much wood do I need for the winter?
That depends on your stove or fireplace, how well the house is insulated, the climate and how much you rely on wood. We do not give a figure because it varies so widely. Track what you burn in a few weeks and enter the number of cords you want in the planner mode for the stack size.
How big should my woodpile be for 3 cords?
Three cords is 384 cubic feet. At a stack 4 feet high and 16 inches deep, you need a length of 72 feet. Use the planner mode to enter the height and depth you have room for and the calculator gives the length, or you can stack in several shorter rows.
How many cords of wood is a 4x8 stack?
A stack 4 feet high and 8 feet long is a full cord only if it is also 4 feet deep. If it is one 16 inch log deep, it is a face cord and about 1/3 of a cord. A stack of 8 by 4 by 4 feet is 1 cord, with a volume of 128 cubic feet.
What is the measure of a cord in metric?
A cord is about 3.62 cubic metres of stacked wood. A cubic metre stack is 35.31 cubic feet, a little over a quarter of a cord at 0.276 cord. Switch the unit to metres or centimetres in the calculator and it converts all of this for you.
How many cords is 1 cubic metre?
One cubic metre of stacked wood is 35.31 cubic feet, so 35.31 / 128 = 0.276 of a cord. Four cubic metres is about 1.1 cords, and 3.62 cubic metres is one full cord. In the calculator, choose metres and enter the stack's length, height and depth.
What is a rick of wood?
A rick is a regional name for a face cord: a stack 4 feet high and 8 feet long that is one log deep. The depth is not fixed, so a rick of 16 inch logs is about 1/3 of a cord, while a rick of 12 inch logs is 1/4. Ask what log length the seller means.
Is a cord of wood stacked or loose?
A cord is defined by a stacked volume, with the logs piled neatly, which is why it includes air gaps. A loose or thrown pile takes more space for the same wood. If wood is delivered loose, stack it and then measure the stack to find what you really received.
How do I know if I got a full cord?
Stack the wood tightly and measure its length, height and depth in feet. Multiply them and divide by 128. If the result is close to 1, you have a full cord. Shorter logs make a face cord, which is a fraction of a cord, so confirm the log length too.
Does firewood length matter for cords?
The cord is fixed at 128 cubic feet, so the log length only changes the shape of the stack. With longer logs the stack is deeper and fewer feet of stack are needed. With shorter logs you need more length or height. The calculator's plan mode finds the stack length for any log length.
How do I plan a woodshed size?
Choose the cords you want to store, the height of the stack and the depth, which is the log length. The planner finds the length. For 3 cords at 4 feet high and 16 inches deep you need 72 feet of stack. Leave extra room for airflow behind and between the rows.
How do I convert face cords to cords?
Divide the face cord's volume by 128 cubic feet. For a face cord 4 feet high and 8 feet long, that volume is the log length in feet times 32. With 16 inch logs, 1.333 feet times 32 is 42.67 cubic feet, and 42.67 / 128 is one third of a cord.
Is a cord the same everywhere?
In the US a full cord is 128 cubic feet, a standard measure. Terms such as face cord, rick and fireplace cord are less standard and differ by region and seller. Check the rules where you buy and confirm the log length, since the legal definition depends on where you live.
What size is a cord in inches?
A cord is 48 inches high, 48 inches deep and 96 inches long, which equals 221,184 cubic inches or 128 cubic feet. In the calculator you can enter the stack in inches directly, and the unit conversions to cubic feet and metres are done for you.
Can I calculate cords from a trailer or truck bed?
Yes. Measure the load as stacked: its length, the height of the wood and the width or depth. Enter them in feet or inches. If the logs are thrown in rather than stacked, the result is only approximate, because the air gaps in a loose load are larger than in a neat stack.
Does the calculator account for seasoning or moisture?
No. A cord is a volume of stacked wood, so moisture content does not change the measure, though the wood will shrink a little as it dries. The calculator converts your stack's dimensions to cubic feet, cubic metres, cords and face cords, plus a cost if you enter a price.
How many logs are in a cord of wood?
There is no fixed number, because the count depends on the diameter and length of the logs. A cord is a volume of 128 cubic feet of stacked wood. Smaller split pieces make more logs in the same volume. Measure the stack and use the calculator to confirm the cords.
How many cords are in a truck bed?
Multiply the length, width and filled height of the bed in feet and divide by 128. A bed 8 feet by 4 feet filled to 2 feet is 64 cubic feet, a half cord. Loose, thrown wood occupies more space than stacked wood, so stack and measure for a true figure.
How do I convert cords to cubic feet?
Multiply the cords by 128. Half a cord is 64 cubic feet, one and a half cords is 192 cubic feet and 3 cords is 384 cubic feet. To go back, divide the cubic feet by 128. The calculator shows both in feet and metres.
How do I convert cubic feet to cords?
Divide the cubic feet by 128. A stack of 120 cubic feet is 0.9375 cord and one of 42.67 cubic feet is one third of a cord. Enter the stack's length, height and depth and the calculator converts it for you.
How much space does a cord of wood need?
A full cord occupies 128 cubic feet, such as 4 feet high, 4 feet deep and 8 feet long. Leave extra room around the stack for air flow and access. The planner mode returns the stack length for any height and depth you choose.
How do I price a partial cord?
Multiply the price per full cord by the fraction of a cord. A third of a cord at $250 is $83.33, and half a cord at $300 is $150. Enter your price per cord in the calculator and it multiplies by the cords in your stack.
