What is the best thickness for a log cabin?

If you like spending time in the garden during summer months but want to make the most of it during colder months too, a log cabin can offer the perfect, cosy retreat. The best thickness for your log cabin will depend on how you want to use it and how much you want to use it. A log cabin can create the perfect space for hobbies, working or relaxing in your garden.


Log cabins vary in thickness, which ranges from 19 mm, 28 mm, 35 mm, 44 mm and right up to 70 mm. These all offer different levels of durability and strength. The thicker the logs, the stronger the building and the more often it can be used throughout the year. Check out the best sellers for each thickness below:

Pros and Cons 


There are pros and cons to each log thickness so it’s important to choose the right one. Once you know which thickness is suited to your needs, you can choose a cabin which is equipped for how and when you want to use it.


19 mm – 28 mm thick timber walls


The cheapest log thickness option is the 19 mm. This is one of the most popular options due to its budget-friendly price. As it has an interlocking construction, the 19mm log thickness offers good durability but it is not as weatherproof as some of the thicker log cabin options. This size thickness is suitable for summerhouse cabins which will be used in the warmer months and a single glazing option is recommended. If you’re looking for a space to relax with friends and family during spring and summer, a 19 mm cabin is an ideal choice.

The next size up is the 28 mm log cabins. These buildings have a stronger build and are ideal for more premium style summerhouses. However, these, too, are only recommended for Spring and Summer use. If you have a workshop which you use for DIY projects during warmer months, a 28 mm building is a great choice.


35 mm – 44 mm thick timber walls 


After this, there are the 35 mm log cabins. These offer good strength and are recommended for use in Autumn as well as Spring and Summer. With a building you’ll be using for three of the four seasons, you should opt for double glazing. These are more expensive buildings than the 28 mm and after worth paying the extra to upgrade to 44 mm log cabins.

44 mm log cabins are constructed using double tongue which is 57% thicker than 28 mm. These buildings are more equipped for harsh weather conditions and offer great durability for heavy duty uses. Double glazing is also recommended to provide good insulation. If you’re looking for a building which is built for all four seasons, you should opt for a 70 mm log cabin.


70 mm thick timber walls 


The largest log thickness available for cabins is the 70 mm option which is available on the bigger cabins. These use extra purlins to make the building strong and supported as well as weatherproofing the cabin from weather conditions all year round. If you want somewhere to work or relax in all year round, a 70 mm cabin is the perfect choice. These are often much more expensive, so if you don’t intend to use the cabin during winter, you should choose a smaller thickness such as the 44 mm or 28 mm.
