Firewood Volume Converter: Cubic Metre, Bulk Bag & Nets

By the The Wood Burner team · Updated 2026

Firewood in the UK is sold in units that never quite match: a loose cubic metre, a dumpy bag, small nets, a barrow load. The catch is loose vs stacked. Tip a stacked cubic metre of logs into a heap and the air gaps swell it to roughly 1.5 loose cubic metres, so two sellers quoting "a cubic metre" can hand you very different amounts of wood. Pick a unit below and see it converted into all the others.

What are you starting with?

Two honest tips when comparing quotes. First, always ask a seller whether their "cubic metre" is loose or stacked; the stacked figure is the one that tells you how much solid wood you are getting. Second, small nets are the most expensive way to buy logs by volume: it takes roughly 40 of them to fill a single loose cubic metre, so they suit a fire pit or the odd evening rather than heating a room all winter.
