Mortar Calculator
Estimate the amount of mortar needed for a masonry wall.
How It Works
Mortar (ft³) = (Bricks ÷ 1000) × 27 × (Joint ÷ 0.375). 60 lb bag ≈ 0.5 cu ft.
Example
For 1,000 bricks at 3/8 in joints: 27 cu ft = 1 cubic yard → 54 × 60 lb bags.
Frequently Asked Questions
How much mortar does a batch make?
A 60 lb bag of mortar mix yields about 0.5 cu ft of wet mortar.
How many bricks does a bag lay?
Roughly 18–20 bricks per 60 lb bag at standard 3/8 in joints.
Why scale by joint thickness?
Thicker joints consume more mortar per brick, so the volume grows in proportion.
