Mortar Calculator
Mortar Calculator
Estimate joint mortar and split cement and sand quantities.
Mortar fills the spaces between masonry units. Its consumption changes when brick dimensions, joints or the wall thickness change.
Measure net masonry and use brick sizes that match the delivery. The calculator separates an estimated mortar volume into cement and sand for your selected proportions.
How to use Mortar Calculator
- Choose measurement unit. Enter wall length, wall height, wall thickness and opening area.
- Enter brick length, brick width, brick height and mortar joint.
- Enter sand parts per cement part, dry volume factor, cement bag mass, cement density and ordering allowance.
- Enter cement bag price and sand price.
- Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
The estimate follows the wall and its units, giving you a clearer basis than applying one bag allowance to every room.
Before you use the result
Mortar volume is net masonry minus estimated brick solids. Bond and site loss can change consumption.
Questions about Mortar Calculator
Why might site consumption differ?
Bond details, joint variation and handling losses can change the amount used. Compare the first completed section with the estimate before ordering later batches.
What should I check before using Mortar Calculator?
Check Measurement unit, Wall length, Wall height and Wall thickness. Use the exact units shown beside the controls and replace any example values with your own inputs.
