Mulch Calculator for Pathways

Estimate mulch for garden paths and walkways.

Bark or wood-chip pathways are usually laid about 3 inches deep over a weed barrier for a soft, natural walking surface. Enter the path length and width below; for long narrow paths the Rectangle shape works well.

Tip: Lay landscape fabric under a mulch path to slow weeds and keep the chips from sinking into the soil.

How it's calculated

1 cubic yard covers about 324 sq ft at 1 in deep / about 108 sq ft at 3 in deep; one 2 cu ft bag covers about 12 sq ft at 2 in deep.

Mulch Calculator for Pathways FAQ

How deep should a mulch pathway be?

About 3 inches over landscape fabric gives a firm, comfortable path. Top it up by an inch each year as it settles.

How much mulch for a path?

Multiply length × width for the area, then use a 3-inch depth. A 3 ft × 30 ft path (90 sq ft) needs about 0.8 cubic yards.
