The load size you require is probably determined by the size of your log store. The sizes in cubic metres that we list are for loose logs rather than stacked. When stacked the logs will take up less space.
To give you some idea of the size of the loads we deliver, here are some pictures of one of our trucks. The whole truck contains 3 cubic metres - which we can partition into either two 1.5 cubic metre loads or three 1 cubic metre loads.
