Calculators are available online that you can use as a brick estimator. These calculators allow you to estimate how many bricks and how much mortar you need to purchase for the project you are working on. You must enter the width (horizontal) and the length (vertical) of the structure you are looking to brick. These calculators then ask for the size of the areas that you will not be putting
. brick on (ex: doors and windows). These areas are deducted from the total size of the project. The use of these types of calculators help make purchasing supplies much simpler with less chance of error. You can find more information here: http://www.csgnetwork.com/brickgeninfocalc.html
