Decomposed Granite vs Pea Gravel: 2026 Comparison
Side by side on size, drainage, compaction, look, and cost. No fluff, just the numbers and the trade-offs.
Quick take
Decomposed Granite is a decorative material in the 0 – 1/4″ range, most often spec’d for walkway gravel. Pea Gravel sits in the same category but runs 1/4 – 3/8″, and it shows up more on patio gravel work.
How the two differ in practice
Size is the first split: 0 – 1/4″ for Decomposed Granite versus 1/4 – 3/8″ for Pea Gravel. Drainage runs moderate on Decomposed Granite and very fast on Pea Gravel. On compaction, expect stays loose from Decomposed Granite, while Pea Gravel delivers stays loose, rolls underfoot. Density is 3000 lb/yd³ next to 2800 lb/yd³, which moves the cost-per-ton math by a small margin. Delivered cost is $50-$95/ton for Decomposed Granite and $45-$95/ton for Pea Gravel.
When Decomposed Granite is the right call
Pick Decomposed Granite when the job is walkway gravel and patio gravel. The warm tan to gold dust grade and the way it stays loose make it a fit for that application. On a full-truck order the per-ton cost falls roughly 15 to 20 percent under partial-load pricing, which is the cleanest way to land in the $50-$95/ton band.
When Pea Gravel is the better fit
Switch to Pea Gravel if the project leans toward patio gravel and walkway gravel. The smooth, rounded, tan / mixed grade plus the very fast drainage profile matches that job better. Plan for $45-$95/ton delivered, same full-load break point as Decomposed Granite.
