A stepping stone path works when the spacing matches your stride. Enter the path length, stone size and gap to get the count and the sand to bed them.

How it works

Path length in inches รท (stone size + gap) gives stones per line, rounded up. Sand is figured at 2 inches under each stone.

Before you order

  • Walk the line in normal shoes and mark each footfall before you set a stone.
  • Bury stones so the top sits about level with the soil and mowers can pass.
  • Leave wider gaps if you want low plants growing between them.

Common questions

How far apart should stepping stones be?
