Free Delivery On Logs – Compare Volumes – FAQs
Log Length: 35cm (13.8 inches). Tolerance on length is +/- 10%. Log Diameter: 8-20cm (4-8″) measured across widest point of the log. Tolerance on diameter is +/- 10%.
Large Logs, Steadier Heat, Fewer Top-Ups
Choose 35cm kiln dried large logs for a wider stove firebox, substantial open fire or suitable outdoor burner. These split oak and birch firewood logs are longer and thicker than FirewoodFund’s standard-size logs, giving established fires a substantial fuel load with fewer individual pieces.
Each log has a standard length of 35cm (13.8 inches) and a diameter of approximately 8–20cm, with a tolerance of +/- 10%. The oak and birch are responsibly sourced from Eastern European woodland, kiln dried to below 20% moisture and certified Ready to Burn.
Select either a medium or large stacked crate according to how regularly you burn and how much storage space you have available.
35cm Firewood for Bigger Fireboxes
Most standard firewood logs are approximately 25cm long. At 35cm, these large logs are designed for appliances and fireplaces with enough usable width to accommodate a longer piece of firewood safely.
Their larger format can provide several practical advantages:
- Fewer individual logs are needed to fill a wide firebox.
- Larger pieces generally burn more gradually once the fire is properly established.
- The oak and birch mixture combines the steady burning characteristics of oak with the more readily ignited nature of birch.
- The logs arrive kiln dried and ready to use without further seasoning.
- Stacked crates provide a substantial supply for regular stove or open-fire users.
For a closer explanation of how length and diameter influence a fire, read the guide to log sizes and burn performance.
Check That 35cm Logs Will Fit Before Ordering
Large firewood is only advantageous when it is suitable for the appliance.
Measure the usable internal width of your firebox and check the maximum log length stated by the manufacturer. The logs should fit comfortably without being forced against the sides, door or internal components.
If you have an average-sized stove, FirewoodFund’s standard 25cm kiln dried logs are likely to offer a more practical fit.
These products are split firewood logs intended for burning. They are not whole tree trunks, uncut forestry logs, landscaping timber, decorative garden logs or building logs. FirewoodFund no longer supplies extra-long 50cm firewood logs.
Choose the Right Crate for Your Storage Space
Both options contain the same 35cm oak and birch logs. The difference is the quantity supplied and the height of the crate.
| Option | Internal crate dimensions | Stacked volume | Equivalent loose volume | Best suited to |
|---|---|---|---|---|
| Medium 35cm oak and birch log crate | 115cm × 108cm × 69cm | 0.85m³ | 1.42m³ | Customers wanting large logs without committing to the biggest crate |
| Large 35cm oak and birch log crate | 115cm × 108cm × 111cm | 1.37m³ | 2.29m³ | Regular users with sufficient storage who want to reduce how frequently they reorder |
Loose volume appears greater because it includes the spaces that would exist between randomly tipped logs. The stacked measurement provides the most useful comparison of the actual quantity of wood.
You can compare these products with other bulk bags and crates using the FirewoodFund firewood volume comparison chart.
Oak and Birch: Two Hardwoods with Different Strengths
These large kiln dried logs contain a mixture of oak and birch.
Birch generally catches more readily and produces a lively flame, while the denser oak contributes a steadier burn once the fire is established. Using both species provides a practical balance for customers who want responsive lighting followed by sustained heat.
For best results, establish the fire with dry kindling and smaller pieces of firewood before adding the larger 35cm logs to a hot firebed. Burn time will always vary according to the appliance, airflow, fuel load and the way the fire is operated, so follow your appliance manufacturer’s instructions.
Large Log Delivery and Storage
The medium and large crates are palletised for delivery to your home. Free weekday pallet delivery is available to most mainland UK addresses.
Pallet delivery may be kerbside, and final placement depends upon vehicle access, the available surface and conditions at the delivery address. Before ordering, read the full large-log delivery information, particularly if your road is narrow or access to the property is restricted.
Plan where the logs will be stored before choosing your crate. Keep firewood raised off the ground, protected from direct rain and surrounded by sufficient airflow. The guide to storing logs outside provides further practical advice.
Your Order Helps Support Tree Planting
Ordering firewood from FirewoodFund also helps put something back.
For every order placed online, money is donated towards tree planting in the UK. This applies whether you choose the medium crate, the larger quantity or another product from the FirewoodFund range.

Frequently Asked Questions About Large Logs
How long are these large logs?
The standard length is 35cm or 13.8 inches, with a tolerance of +/- 10%. They are approximately 10cm longer than FirewoodFund’s standard firewood logs.
Are these “big logs” suitable for every wood burner?
No. They are intended for wider fireboxes, large open fires and other suitable appliances. Check the manufacturer’s maximum permitted log length and measure the usable firebox space before ordering.
Are these whole or uncut logs?
No. They are split, kiln dried firewood logs prepared for burning. They are not whole trunks, unsplit timber or logs intended for landscaping, building or woodcraft.
Where do the logs come from?
The oak and birch in these 35cm products are responsibly sourced from Eastern European woodland. FirewoodFund’s wider range contains both British and European-sourced products, with provenance varying by product.
Do large logs burn longer?
Under comparable conditions, a larger piece of firewood will generally burn more gradually than a smaller piece. Actual burn time depends on the wood species, moisture content, stove, airflow and fuel load. Large logs should be added after the fire is properly established and used according to the appliance manufacturer’s instructions.
