Gravel driveways are a cost-effective, low-maintenance option for homeowners looking to boost curb appeal and durability.

In this guide, we’ll break down the different gravel sizes used in driveways, what each size is best for, and how to make the right choice for your project.

Why Gravel Size Matters

The size of gravel you choose affects more than just appearance—it directly impacts drainage, stability, comfort underfoot, and how well the driveway holds up over time. The wrong size can lead to ruts, poor drainage, or frequent maintenance. The right size creates a durable, easy-to-maintain surface that lasts for years.

Common Gravel Size Categories

Here’s how other common sizes compare:

Small Gravel (⅜” or smaller)

• -Also called pea gravel
• -Smooth and decorative
• -Best for walkways or top-dressing, not ideal as a base layer
• -Can shift easily under vehicle weight

Medium Gravel (½” to ¾”)

• -Often used as a middle layer or decorative topping
• -Can work for low-traffic driveways
• -Offers a balance of compaction and drainage
• -May require periodic raking to keep level

Large Gravel (1″+)

• -Great for very heavy vehicles or deep base layers
• -More difficult to walk on
• -Can look less refined, but highly functional
• -Often used in rural, industrial, or commercial settings

Installation Basics

A properly installed gravel driveway includes multiple layers:

1. Sub-base Layer (4–6 inches)
   • Typically larger crushed stone (1½” or crusher run)
   • Provides load-bearing support
2. Base Layer (3–4 inches)
   • Use ¾” to 1″ crushed stone
   • Key layer for compaction and drainage
3. Top Layer (2 inches) (optional)
   • Smaller gravel for aesthetics or comfort
   • Pea gravel or decorative gravel can be used here

All layers should be compacted thoroughly for best results. Building a driveway with several layers of different-sized stones is not completely necessary. Here is a video about how to build a gravel driveway.

Tips for Choosing the Right Gravel

• Project Scale: Use ¾” crushed stone for standard driveways; consider 1½”+ for heavy trucks or rural roads
• Climate: In areas with heavy rain or freeze-thaw cycles, drainage is critical—avoid fine material that traps moisture
• Budget: Smaller gravel tends to be cheaper but may require more maintenance
• Look and Feel: Crushed stone gives a rugged, angular finish. Rounded river rock is smoother but can shift more easily.

Final Thoughts

Choosing the right gravel size is key to building a driveway that performs well and looks great. For most homeowners, ¾ to 1 inch crushed stone is the go-to choice for both strength and aesthetics.
