Calculating Material for Your Retaining Wall Project
There are a couple of ways to determine how much block material your project requires. If you’ve already decided what type of block you want, then use our Retaining Wall Block Calculator to estimate how many blocks you’ll need. You can also use the examples below as guides and adjust them to fit your project. Your material needs may vary depending on your specific design. Before you buy materials or begin work, check local building codes and your homeowners association regulations to see if there are any restrictions or requirements you need to follow. A permit may be mandatory in some areas.
This guide provides instructions for estimating materials for a wall constructed of retaining wall blocks. For instructions on building a wall with concrete blocks (sometimes called cinder blocks) and mortar, see Laying Block.
