Log Store Size Calculator: What Size Log Store Do I Need?

A log store has to hold your wood and let air move through it, so its internal volume is always bigger than the solid wood inside. This calculator sizes the store you need for a given amount of firewood, or checks whether a store you are eyeing up is big enough. The catch most people miss: stacked logs are roughly one third air gaps.

How the maths works: neatly hand-stacked split logs occupy about 1.5 times the volume of the solid wood, because of the gaps between them. So a store needs roughly 1.5 cubic metres of internal space for every cubic metre of solid firewood you want to keep. We use that 1.5 factor throughout, and we assume you fill the store fully. Leave the bottom off the ground on bearers and the back open for airflow so the wood keeps drying rather than going mouldy.
