Pea gravel is the least standardized product we sell, and the one most likely to arrive looking different from what someone pictured. That is not a supplier problem — it is that "pea gravel" describes a size, roughly 3/8 inch, and says nothing about shape, color, or how it was made. Two yards can both sell you pea gravel and hand you materials that behave nothing alike.
The first is true pea gravel: naturally rounded stone, tumbled smooth by water, usually pulled from a river deposit. Mixed tan, brown, and grey. Smooth underfoot, and it rolls.
The second is a crushed chip at the same size — sometimes called 3/8 chip, playground chip, or just sold as pea gravel because that is what customers ask for. It is angular rather than rounded, since it was crushed rather than tumbled, and it is usually more uniform in color because it came from one quarry rather than a riverbed.
Around here, the chipped version is more common than the rounded version. If you have a specific look in mind, that is worth knowing before you order.
Rounded stone does not lock together. Step on it and it shifts; drive on it and it displaces into ruts with berms along the tire tracks. That makes it comfortable to walk on barefoot and genuinely bad as a driving or parking surface. It also migrates downhill on any real slope, so on a graded yard it ends up piled at the bottom within a couple of seasons.
Angular chip locks. The sharp faces wedge against each other, so it holds a surface better, stays put on a slope, and firms up underfoot. It is less pleasant barefoot and it does not have the same soft, river-washed look.
Neither is better. They are different products for different jobs, and the failure mode is ordering one while picturing the other.
For a play area, a dog run, or anywhere bare feet go, you want the rounded stone. Smooth is the entire point.
For a path, a side yard, or anything on a grade, take the angular chip. It stays where you put it and you will not be raking it back uphill every spring.
For a driveway or parking pad, neither one. Pea gravel of any kind is the wrong product for vehicle traffic — it has no fines to bind it, so it never compacts into a surface. What you want there is road base. People do put pea gravel on driveways, and it is why you see driveways with a berm down the middle and bare tracks either side.
For drainage — around a French drain, a dry well, or a downspout outlet — either works, and washed is what matters more than shape. You want the fines rinsed out so water moves through freely.
This is the thing we get asked about most and the thing we can promise least. Rounded pea gravel is a natural mix, and the mix varies by deposit and even by how deep in the pile it came from. A load delivered in spring can read noticeably warmer or greyer than the same product in fall.
If matching an existing area matters to you, order a little extra now rather than topping up in two years, and expect a visible seam if you do have to add later. If a consistent grey is what you are after, a crushed grey product will hold its color far better than any natural rounded stone will, because it comes from a single quarry face rather than a mixed deposit.
Two to three inches covers most decorative uses. Deeper than three inches and it gets unpleasant to walk on — your foot sinks rather than staying on top.
A ton covers roughly 100 square feet at two inches deep, though this shifts with the specific stone. Our calculator uses the real density for whatever you pick rather than a rule of thumb.
Lay it over a woven fabric if the ground underneath is clay. Small stone works its way down into clay faster than larger material does, and without separation you lose depth and gain mud within a couple of seasons.
If the exact appearance matters for your project, tell us when you order and we will let you know what is actually available rather than guessing. That is a much better conversation to have before the truck shows up than after.
