Ever wondered just how many logs in a builders bag you can expect to see?
This handy guide breaks down the key factors that determine the number of logs that fit inside this staple of any firewood delivery.
How Many Logs in a Builder’s Bag?
A standard builder’s bag contains approximately 400 logs when filled with kiln-dried hardwood cut to 10 inches in length.
The exact number can vary slightly based on the size of the bag and logs.
Key Points
- Builder’s bags are commonly 0.7 cubic meters in size
- They can hold around 200kg or 400 logs of kiln-dried hardwood
- Log size, wood type and moisture content affect the total log count
- You can expect approximately 400 logs in a standard builder’s bag
Our Opinion
In my experience as a firewood supplier, a standard 0.7 cubic meter builder’s bag filled with kiln-dried hardwood logs cut to 10 inches will contain around 400 usable logs on average.
This provides a good estimate of the number of logs you can expect when purchasing a bag of firewood.
However, factors like bag size, log dimensions and wood type can cause the actual amount to vary somewhat above or below 400 logs per bag.
How Many Logs Fit in a Standard Builder’s Bag?
The most common size of a bag used for logs, also known as “dumpy bags” or “bulk bags”, can hold about 0.7 cubic meters of logs. These logs are less dense than sand or gravel, so they weigh less. A typical “tonne bag” of mixed traditional logs with a moisture content of 20% weighs around 200 kg.
The size of a builder’s bag can vary, with dimensions of either 100cm x 100cm x 100cm or 90cm x 90cm x 90cm. This can affect the number of logs you receive. For example, a 100cm x 100cm x 100cm bag can hold more logs than a 90cm x 90cm x 90cm bag.
A builder bag is usually 800x80x800, which is half a cubic meter. These bags are designed to carry a ton of sand, but they can now hold up to 800 kg. When using a wood-burning stove all day, you can expect to use between 3-4 cubic meters of loose logs per day. On average, a single barrow bag of logs will last about 2 weeks or more.
The bags used for logs measure either 82x82x92 or 85x85x85. In a builder’s bag, you can expect to find around 230-260 logs and usable bits of firewood. The number of logs you receive may vary depending on the size of the bag. There are approximately 400 logs per bag, cut to 10 inches long, with other sizes available upon request.
A large builder’s dumpy bag is filled with mixed species hardwood logs, all with a moisture content below 20%. These logs are kiln-dried and ready to burn.
When ordering a delivery of logs, the number of builder’s bags you receive will directly correlate to the total capacity. So, a single bag will give you 0.5 cubic meters of logs, while two bags double that capacity to 1 cubic meter, and so on.
Knowing the typical capacity allows you to easily estimate how many bags you need to order based on your total log volume requirements. This ensures you get the right number of logs to stock up for the season.
Key Factors That Influence Log Capacity
When figuring out how many logs fit in a builder’s bag, there are a few key factors that come into play.
The main elements are:
- Log diameter – Thicker logs take up more space, so you can fit fewer in a bag.
- Log length – Longer logs reduce capacity as there is less space to fill.
- Wood density – Hardwoods like oak are denser than softwoods like pine.
- Moisture content – Wet, freshly cut logs weigh more than seasoned, dried logs.
- Bag dimensions – Some bags may be taller or shorter than the standard 0.75 cubic meters.
Understanding how these variables influence overall capacity can help you estimate your needs. For example, if using thicker, heavier hardwood logs, plan for a lower volume per bag versus thinner, lighter softwoods. Adjust bag quantity accordingly.
You can maximize capacity by using uniformly cut logs around 2-3 inches thick and keeping length consistent. Mixing log sizes reduces usable space. Seasoned logs also take up less room than freshly harvested wet logs.
While the standard builder’s bag capacity is 0.75 cubic meters, carefully considering log characteristics ensures your estimate is accurate, so you get the right amount of logs per bag for your needs.
Builder’s Bag Sizes and Dimensions
When looking at builder’s bags, you’ll notice they come in different sizes. This affects how many logs you can fit inside.
The typical builder’s bag has these dimensions:
- 1-meter-wide x 1-meter-high x 0.75 meters deep
- Total volume of 0.75 cubic meters
However, some brands offer shorter or taller options such as:
- 0.5 cubic meter bags – 0.8 meters high
- 1 cubic meter bag – 1.2 meters high
The width and depth tend to stay the same. It’s the height that varies most between bag sizes. This directly impacts the total cubic meter volume and log capacity.
When estimating how many logs you need, first check the dimensions of the specific builder’s bags you’ll be using. A 1-meter-tall bag holds more logs than a 0.8-meter bag of the same width and depth.
Opt for taller, larger capacity bags if you need to maximize the number of logs per bag. Just keep in mind that larger bags will be heavier to lift when full.
Knowing the exact bag dimensions is key to accurately calculating the log capacity and buying the right quantity.
Storing Logs – Alternate Options Like Crates and Nets
Builder’s bags are the most common way to transport and store logs, but they aren’t the only option.
Plastic or metal crates can also hold logs neatly in place. The rigid structure prevents logs from rolling around. Crates are often the same volume as builder’s bags. A 1 cubic meter crate holds about the same quantity of logs as a 1 cubic meter bag. The benefit of crates is they stack securely for compact storage. The solid walls also fully protect logs from weather damage.
However, crates lack the flexibility of bags. They can’t conform to irregular log shapes as easily. Loading and unloading each log is also slower with a crate.
For a lightweight alternative, log nets are an interesting choice. These strong nylon nets wrap bundles of logs together. Hooks or ropes then allow for suspending the bundle for storage. Nets prevent logs from shifting around. And they’re much easier to carry than rigid crates or bulky bags.
Just be aware that net bundles leave logs more exposed. Make sure to store them somewhere dry. Nets also require overhead structures for hanging.
Overall, traditional builder’s bags strike a good balance of protection, ease of use, and flexibility. But crates and nets can work in certain situations.
