Enter how many blocks or bricks you're laying to find the number of mortar mix bags to buy.
Estimate only — joint thickness and unit size shift actual coverage per bag.
Standard rules of thumb: about 3 bags of mortar mix per 100 concrete blocks, or about 7 bags per 1,000 bricks. Both assume typical joint thickness (3/8 in) — a thicker joint or larger unit face uses more mortar per piece.
About 3 bags of standard mortar mix per 100 concrete blocks, assuming typical 3/8 in mortar joints.
Yes — larger units (like standard blocks) need less mortar per square foot of wall than smaller units (like bricks) because there's less total joint length for the same wall area.
