Barefoot-friendly gravel

Questions and preferences

The earlier question sought smooth or polished gravel that feels good barefoot for a 30 × 12 ft area: 360 sq ft. Barefoot comfort is a requirement; a product that only looks rounded is not sufficient.

Compare shape, size, and movement

Option explored	What to test
Rounded pea gravel	Pressure underfoot, shifting, tracking into other areas
Tumbled small pebbles	Consistency of size and smoothness
Beach pebbles	Whether larger stones feel unstable or uncomfortable
Resin-bound aggregate	Actual texture, drainage system, aging, and repair

The earlier answer suggested approximately ⅜-inch rounded material as a starting point. Treat that as a sample to test, not a guarantee of comfort. A loose stone can press into the foot despite a smooth surface.

Test the assembly

Make a sample area using the proposed depth, base, and edging. Walk on it barefoot, stand, turn, and test it wet. Compare hot sunny conditions with shade. Surface color and exposure affect temperature.

Drainage, soil separation, weed management, containment, and accessible transitions belong to the design. A loose layer that is too deep can be difficult to walk through; a thin layer can expose the base.

Quantity arithmetic

For the 360 sq ft area:

Illustrative depth	Geometric volume
2 inches	60 cu ft = 2.22 cu yd
3 inches	90 cu ft = 3.33 cu yd

These are volume calculations, not a selected installation depth. Allowance for compaction, settlement, waste, and supplier measurement must be established. Convert to weight using the supplier’s bulk density.

Decisions still open

The actual aggregate, base, edging, drainage detail, and installation quote remain unselected. Earlier cost estimates are historical, not current bids.
