How Much Does a Crate of Logs Weigh?
If you’re buying firewood for a wood burner, stove or open fire, one of the most common questions people ask is:
how much does a crate of logs weigh?
The honest answer is that there is no single fixed weight. A crate of logs can vary by hundreds of kilograms, even when the crate itself is the same size.
That’s because log crate weight depends primarily on:
- The species of wood
- How dry the logs are (moisture content)
- How the logs are stacked within the crate
This guide explains all of that clearly and provides realistic weight ranges based on specific crate sizes, broken down by wood species, so you know what to expect before ordering.
Why the Weight of a Log Crate Varies
Firewood is a natural product, not a uniform commodity. Two crates that look identical can feel completely different when delivered.
1. Wood species (density)
Different species have very different densities:
- Oak is extremely dense and heavy
- Ash is slightly lighter but still a dense hardwood
- Birch is lighter again
- Softwoods are significantly lighter than hardwoods
Denser woods generally burn longer and hotter — but they also weigh more per cubic metre.
2. Moisture content
Water adds substantial weight:
- Fresh or wet logs can be 30–50% heavier
- Properly kiln dried logs (≤20% moisture) are far lighter and more consistent
This is why reputable firewood suppliers avoid quoting exact crate weights.
Crate Sizes & Internal Volumes Used in This Guide
All weight guidance below is based on the internal stacked volume of the following crate sizes, which most accurately reflects how logs are delivered and handled.
| Crate Size | Internal Dimensions (W × D × H) | Internal Stacked Volume | Internal Loose Volume |
|---|---|---|---|
| Medium Crate | 115 × 108 × 69 cm | 0.85 m³ | 1.42 m³ |
| Large Crate | 115 × 108 × 111 cm | 1.37 m³ | 2.29 m³ |
| Extra Large Crate | 115 × 108 × 149 cm | 1.84 m³ | 3.08 m³ |
All weights below assume kiln dried logs at or below 20% moisture content.
How Much Does a Crate of Logs Weigh by Species?
Oak Log Crate Weight (Kiln Dried)
Oak is one of the heaviest and most energy-dense firewoods available.
| Crate Size | Approximate Weight |
|---|---|
| Medium (0.85 m³ stacked) | 600 – 720 kg |
| Large (1.37 m³ stacked) | 960 – 1,150 kg |
| Extra Large (1.84 m³ stacked) | 1,290 – 1,550 kg |
Oak delivers long burn times and high heat output but requires solid access for delivery.

Ash Log Crate Weight (Kiln Dried)
Ash is a dense hardwood that offers excellent all-round performance.
| Crate Size | Approximate Weight |
|---|---|
| Medium (0.85 m³ stacked) | 520 – 620 kg |
| Large (1.37 m³ stacked) | 820 – 980 kg |
| Extra Large (1.84 m³ stacked) | 1,100 – 1,320 kg |
Ash is slightly lighter than oak while still producing strong, consistent heat.

Birch Log Crate Weight (Kiln Dried)
Birch is lighter and easier to handle, with fast ignition and a clean flame.
| Crate Size | Approximate Weight |
|---|---|
| Medium (0.85 m³ stacked) | 430 – 520 kg |
| Large (1.37 m³ stacked) | 680 – 820 kg |
| Extra Large (1.84 m³ stacked) | 910 – 1,100 kg |
Birch crates are noticeably easier to manage than oak or ash.

Softwood Log Crate Weight (Kiln Dried)
Softwoods are the lightest option and easiest to move and store.
| Crate Size | Approximate Weight |
|---|---|
| Medium (0.85 m³ stacked) | 320 – 400 kg |
| Large (1.37 m³ stacked) | 510 – 650 kg |
| Extra Large (1.84 m³ stacked) | 690 – 880 kg |
Softwood burns faster and produces less heat per log, but weight is often a key advantage.
What If the Logs Are Not Kiln Dried?
If logs are wet or only partially seasoned:
- Crate weights can increase by 20–50%
- Fresh hardwood crates can exceed 1.7–2.0 tonnes
- Weight may fluctuate depending on rainfall and storage conditions
This is why weight alone should never be used to judge value or quantity.
Does a Heavier Crate Mean Better Value?
Not always — but often yes in terms of heat output.
- Heavier crates usually contain denser hardwood
- Denser hardwood burns longer and hotter
- Lighter crates are easier to handle and may suit smaller stoves or limited access
The best option depends on your storage space, delivery access and how frequently you burn logs.
