Firewood suppliers use a variety of terms to describe quantities, including loose loads, stacked volumes, bags, crates, pallets, and sometimes even weight. Understanding these measurements can help you compare prices properly and make sure you’re getting good value for money.
Loose vs Stacked Logs
The two most common ways firewood is sold are by loose volume and stacked volume, both typically measured in cubic metres (m3).
- Loose firewood is poured into a bag or crate with natural gaps of air between the logs. Although the container may measure 1m3, the actual amount of wood is lower because of these spaces.
- Stacked firewood is carefully arranged to minimise air gaps, meaning you receive more wood within the same volume.
As a result, a stacked cubic metre of logs can contain around 15-20% more wood than a loose cubic metre.
How Firewood is Sold?
Suppliers may sell logs in:
- bulk bags
- crates
- barrow bags
- net bags
- loose tipped
Bulk bags and crates generally offer the best value because they contain larger quantities. Crates often hold neatly stacked logs, while bulk bags usually contain loosely filled logs.
Smaller bags are useful for occasional use or homes with limited storage space.
Measuring Firewood by Weight
Weight can provide a rough guide, but it is not always an accurate way to compare quantities. Wet logs weigh more than dry logs, and different types of wood vary greatly in density. For example, hardwoods like oak and ash are much heavier than softwoods such as pine or spruce.
For this reason, firewood is more commonly measured and sold by volume rather than weight.
The Most Cost Effective Option
Buying in bulk is usually the cheapest way to purchase logs, especially if you have enough storage space. Smaller bags tend to cost more per cubic metre but are convenient for occasional use.
Do Air Gaps Matter?
Air circulation is helpful when storing logs because it allows the wood to stay dry and prevents rot. However, ready to burn logs supplied by certified suppliers are already properly seasoned, so extra air gaps during delivery are not necessary.
If storing logs for longer periods, avoid keeping them in plastic bags, as trapped moisture can damage the wood.
