How deep should a gravel patio be?

Two inches of surface stone over four inches of compacted base, so about six inches of total excavation. Skipping the base is the most common reason gravel patios go lumpy.

What is the best gravel for a patio?

Decomposed granite or #8 crushed stone give the firmest surface for furniture. Pea gravel is more comfortable barefoot but chairs and tables sink into it.

Do I need edging around a gravel patio?

Yes. Without a hard edge, the stone migrates into the surrounding lawn and beds, and you lose depth in the patio itself every season.

Gravel Patio Calculator

A gravel patio that stays comfortable and level needs a compacted base under the decorative surface, not just a layer of pretty stone on dirt. This calculator sizes both courses, plus the fabric and edging that keep them where you put them.
