Gravel is one of the most versatile landscaping materials:
- it lasts: it doesn’t rot or blow away like mulch,
- it drains: water passes straight through, and
- it’s cheap: it costs a fraction of pavers or concrete.
This guide covers the best types of gravel for landscaping, where each one works, how to install it so it stays neat, and how to calculate how much you need. For quick numbers, use the landscape gravel calculator.

Pea gravel
The most popular landscaping gravel. It is smooth underfoot, inexpensive and comes in many natural colors. Angi lists 3/8 inch as the most common size for patios, pathways and fire pits, and 1/4 inch for flower beds, around trees and xeriscaping (Angi). Full details: pea gravel guide.
River rock
Larger, rounded stones, great for dry creek beds, borders and around downspouts. They aren’t comfortable to walk on, so use them as accents rather than paths. Use the stone and rock calculator for larger stones.
Crushed stone and crushed granite
Angular stone locks together, so it makes firmer paths than round gravel. #57 is a common size (1 inch down to about 3/16 inch). See #57 stone explained.
Decorative gravel (white, black, colored)
High-contrast stone that makes plants pop in modern designs. It costs more, so it is usually spread thinner or used in smaller areas.
Where to use gravel in your landscape
- Garden paths: pea gravel or crushed granite, with edging.
- Patios and seating areas: see our gravel patio guide.
- Flower and shrub beds: a mulch alternative that doesn’t decompose.
- Xeriscaping: pairs with drought-tolerant plants and cuts watering.
- Dry creek beds: river rock directs runoff across a yard.
- Around downspouts and foundations: gravel helps water move away from the house.
- Under decks and in side yards: a low-maintenance cover where grass struggles.
How to install landscaping gravel
- Mark the area and remove grass, weeds and roots.
- Excavate a few inches so the gravel sits flush with the surrounding ground.
- Install edging (steel, stone, brick or timber) to keep the gravel contained.
- Lay landscape fabric to suppress weeds and keep the gravel from sinking into soil. Cut X-shaped slits for plants.
- Spread the gravel evenly and rake it level.
- Top up every year or two as the gravel settles.
How deep should landscaping gravel be?
| Use | Typical depth |
|---|---|
| Decorative beds (around plants) | 2–3 in |
| Garden paths | 2–3 in over a compacted base |
| Patio top layer | 2–3 in |
| Driveways (total) | at least 5–6 in (HomeGuide) |
Decorative top layers of about 2–3 inches match HomeGuide’s guidance for the top layer of a gravel driveway (HomeGuide). Thinner layers let soil and fabric show through. Deeper loose stone feels unstable and wastes money. See how much a yard of gravel covers for the full depth chart.
How much landscaping gravel do I need?
Cubic yards = length (ft) × width (ft) × depth (in) ÷ 324
Then multiply by about 1.4 for tons. Dry gravel weighs about 105 lb/ft³ (Engineering ToolBox).
Example: a 30 × 4 ft garden bed at 3 inches
- 30 × 4 × 3 ÷ 324 = 1.11 cubic yards
- 1.11 × 1.4 = 1.56 tons
- Or about 60 bags of 0.5 ft³
Quick coverage per cubic yard:
| Depth | Coverage per cubic yard |
|---|---|
| 2 in | 162 sq ft |
| 3 in | 108 sq ft |

Landscaping gravel tips
- Always use edging. It is the single biggest factor in keeping gravel areas tidy.
- Pick angular stone for walking surfaces and round stone for looks.
- Match the color to your house and hardscape. Light stone reflects heat, dark stone absorbs it.
- Order a little extra (5–10%) from the same batch, so colors match when you top up.
- Buy bulk for anything over about half a yard. Bags cost several times more per yard. See how many bags of gravel you need.
