Paver & retaining-wall block coverage

Paver count comes from the face area of one paver: pavers per square foot = 1 ÷ face area, plus waste. Retaining-wall blocks come from the wall face area ÷ the block face. The values below are labeled planning typicals — confirm the size on the product. Use them in the pavers and retaining-wall block tools.
