Frequently Asked Questions

A pea gravel calculator estimates the volume, weight, coverage area, and cost of pea gravel for your landscaping project. It calculates how many cubic yards or tons you need and shows coverage at 2, 3, and 4 inch depths.
For walkways and decorative paths, 2–3 inches of pea gravel is recommended. For areas with foot traffic, use 3–4 inches. Avoid using pea gravel for driveways, as the smooth round stones shift under vehicle weight and don't compact like crushed stone.
A cubic yard of pea gravel typically weighs about 2,565 pounds (1.28 tons). This is slightly lighter than crushed stone because pea gravel has more air gaps between the rounded stones. White pea gravel may be slightly lighter than standard varieties.
One ton of pea gravel covers approximately 80–100 square feet at 2 inches deep, 55–70 square feet at 3 inches deep, or 40–50 square feet at 4 inches deep. Coverage varies based on stone size and shape of the area.
Yes, pea gravel is excellent for drainage due to its round shape that creates gaps between stones. It's commonly used in French drains, around foundation perimeters, in planter bottoms, and as a top layer for dry creek beds and rain gardens.
