What size log store for a bulk bag?

There is no standard storage answer for “one bulk bag”. Get the bag's filled dimensions and the seller's description of its contents, then measure one delivery after stacking.

Why the label is weak

Flexible bags bow out, settle in transit and may be filled to different heights. A nominal bag dimension describes packaging better than it describes the neat stack you will build. Two merchants can use the same casual name for different bags.

A safe buying method

Ask the supplier for width, depth and filled height, plus the approximate log length. If the bag is loose-filled, do not order a store whose claimed capacity merely matches the bag's outer cube. Stacking changes the volume, but posts, floor gaps and roof clearance consume part of the store.

The low-risk approach is to stack the first delivery temporarily on raised bearers under a sound top cover, measure it, then choose a permanent store with 15–20% spare usable capacity.

If you must buy the store first

Choose from internal dimensions, not a “one-bag” marketing label. Keep the width generous, use a single-row depth suited to the supplier's log length, and avoid counting the triangular roof space. Confirm that the delivery can arrive before the old stock is fully used; that overlap often determines the real size.
