What is the correct spacing for stepping stones?

Twenty-four inches on center, measured from the center of one stone to the center of the next. This matches a comfortable walking stride. Closer spacing reads as a paved path. Wider spacing requires an uncomfortable step.

How do I set stepping stones so they don't rock?

Excavate to the full thickness of the stone plus 2 inches. Fill with 2 inches of coarse sand. Set the stone and check for level. Add or remove sand until the stone sits stable without rocking. The stone should bear on the sand across its full face, not on high spots.

Should stepping stones be set flush with the lawn or slightly above?

Flush or very slightly proud — no more than 1/4 inch above the lawn surface. Flush allows mowing over the stones without damage. Proud means pulling the mower over each stone. Below flush means the stones collect water and sink further over time.

Bluestone Stepping Stones — Old Canaan Building Materials

A stepping stone path through a lawn or ground cover is one of the most functional and most underused details in the traditional New England residential landscape. It gets you across the lawn without wearing a track in the turf. It provides a dry surface through wet ground. It reads as barely there — a series of flat stones barely proud of the lawn surface, the turf growing tight to their edges.

The Character

Bluestone stepping stones in a lawn read as the simplest possible path — just stones, just grass. The blue-grey of the stone against the green of the turf is one of the natural color combinations of the New England landscape. Set just at grade, the stones appear to grow from the ground rather than having been placed on it.

What It Is

Stepping stones are Pennsylvania or New York bluestone, natural cleft or thermal finish, minimum 2 inches thick, in irregular or roughly square pieces 18 to 24 inches in their largest dimension. They are set in a prepared bed — excavated to the stone thickness plus 2 inches for a sand setting bed — with the top surface flush with or very slightly (1/4") proud of the lawn surface.

How It Behaves

A correctly set stepping stone sits stable — it does not rock or tip when stepped on. It does not create a raised obstacle that snags the lawn mower. It drains freely. Over seasons it may need to be releveled if frost heave occurs under a poorly drained stone; otherwise it is essentially maintenance-free.

Why It's Right

A bluestone stepping stone path is correct in a traditional New England landscape where the garden transitions between formal and informal areas, where the lawn surface needs to be crossed regularly without wearing a path, or where a full gravel or paved path would feel too formal for the setting.

How To Get It

From stone yards. Specify natural cleft Pennsylvania bluestone, minimum 2-inch thickness, in random irregular pieces averaging 18 to 24 inches. For a path through lawn, set stones at a comfortable walking stride — approximately 24 inches on center from stone center to stone center.

The Old Canaan Standard

Pennsylvania bluestone, natural cleft, minimum 2-inch thickness, set flush with lawn grade in prepared sand bed, at 24-inch spacing on center, for stepping stone paths in lawn and ground cover at traditional New England properties. Set level or with very slight pitch to drain. No mortar. This is the path that barely exists.
