Sizing
Log store dimensions: depth, height and bay width
Choose proportions that match log length, safe reach and manageable stacking rather than capacity alone.
Good proportions make a store easy to fill and empty. Depth follows log length, height follows comfortable reach, and total width follows the volume calculation.
Depth follows the pieces
A single row needs slightly more clear depth than the longest regular logs in the delivery. Too shallow and pieces protrude into rain; needlessly deep and short pieces become a loose heap. Ask your supplier's normal cut length before buying.
Two rows double capacity without doubling frontage, but inspection and first-in-first-out use become harder. Keep air paths at the rear and avoid pushing the second row against a solid wall.
Height is a handling choice
The top row should be placeable without throwing or climbing. Leave a clear gap beneath the roof so the upper surface can release moisture. Count only this usable height in capacity calculations.
Break long fronts into bays
Dividers support the ends of each stack, reduce the distance a collapsing row can travel and make stock rotation obvious. A pair of moderate bays is usually more useful than one unbroken wall of logs.
Allow for the building around the void
External width adds posts and dividers. External depth adds rear battens, fascia and roof overhang. Overall height can include feet and the roof pitch. Mark the full footprint on the ground before ordering, including the door or path space needed in front.
