Material quantities by trade

How to Use This Calculator

Select the trade and enter the measured area, volume or length in the units shown. Check whether openings or exclusions have already been deducted. Set the waste allowance and review the product size, coverage and pack assumptions before placing an order.

Worked Example

With the configured facing-brick coverage of 60 bricks per m², 10 m² and 7.5% waste give an ordering area of 10.75 m² and 645 bricks. Check the specified brick size, bond and manufacturer’s information before ordering.

Before You Use the Result

Check actual dimensions, manufacturer coverage and whole-pack rounding. Change the quantities when the design or site measurement changes. For layered construction, measure each layer separately to avoid an incomplete order.
