About this calculator
This calculator finds how many retaining wall blocks a project needs by dividing the wall's total face area (length × height) by the face area of a single block, then adding a margin for cuts and waste.
Landscapers and hardscape contractors use it to quote jobs and order pallets of block in the right quantity, and homeowners use it to budget a DIY retaining wall or garden edging project before heading to the yard. Enter the wall's length and height along with your block's dimensions to get the count.
