Concrete Block Calculator
Estimate facing blocks with adjustable block dimensions.
Open this toolBlocks cover a wall by their visible face, so width and height matter more than a guess based on floor area.
Measure the wall, subtract openings and enter the block dimensions you intend to buy. Keep cell filling and mortar as separate material requirements.

Why use this tool
Adjustable block sizes let you compare available products against the same wall area before committing to an order.
Before relying on the result
Counts blocks by face area. Cell filling and mortar are separate requirements.
Tool limitations
Counts blocks by face area. Cell filling and mortar are separate requirements.
Questions
Is this also a concrete filling estimate?
No. Hollow cells, reinforcement and filling concrete require separate dimensions and specifications. The block count alone cannot supply those quantities.
What should I check before using Concrete Block Calculator?
