How the estimate works
Quarries sell chop stone by the ton, and a ton covers a set length of border. The presets assume stone four inches thick, and a wider stone covers fewer feet per ton. Pick the width that matches the stone you plan to use.

From Estimate to Order
Find the stone that fits.
These are planning estimates, not structural design or a final order quantity.
Measure the border
Run a garden hose along the edge of the bed and measure it in feet. Count each row of stone as one course along the full length. A border two rows high needs twice the stone of a single row.
Find stone for your edging
Browse building stone in the catalog to compare widths and colors. Our garden edging guide shows how to pick a border that suits the bed.
