Flat Limestone Rocks for Walkways: Thickness, Spacing, and How Many Stones to Order
A path of flat limestone rocks is a small project with an outsized payoff: a few dozen stones, a weekend of work, and the route everyone actually walks, from the driveway to the door, from the porch to the shed, stops being a mud track. Flat limestone is the stone most buyers land on for walkways because it does three things at once. It sits flat, it grips underfoot when wet, and its buff-to-gray color looks at home against almost any Arkansas house.
The difference between a path that stays put for twenty years and one that rocks, tilts, and cracks is almost entirely in which stones you pick and how thick they are. Here is how to choose flat limestone rocks that last, and how many to order. Rockhouse Stone stocks and sells the stone; the setting is a genuinely doable homeowner project, and we will send you off with everything you need to do it right.
Steppers, flagstone, and slabs: know which one you are buying
- Steppers are individual flat limestone rocks, roughly 18 to 24 inches across, sold by the piece or pallet. One stone equals one footstep. This is the classic garden path.
- Flagstone is broader, thinner material laid edge to edge to make a continuous surface, a patio or a solid walkway. If that is your project, start with our guide to Arkansas flagstone types and colors.
- Slabs are the oversized pieces, three feet and up, used as landings, bridge stones, and grand single steps.
This post is about the first kind. Steppers forgive imperfect ground, go down one stone at a time, and let a path curve naturally around trees and beds in a way poured walks never do.
Thickness is the whole ballgame
Set directly in soil, a stepper needs to be 1.5 to 2.5 inches thick. Thinner stone flexes over any void under it and cracks the first time a wheelbarrow rolls across. Thicker than about 3 inches gains you nothing on a footpath and makes every stone a two-person lift.
Just as important: pick stones with consistent thickness across the piece. A stepper that is 2.5 inches on one edge and 1 inch on the other will never sit flat no matter how much you fuss with the ground under it. This is the single best reason to pick your stones in person at the yard. Flip a candidate on edge, sight down it, and you will know in two seconds.
Size and spacing: match the stone to a stride
An 18 to 24 inch stepper catches a full footfall with margin. Space the stone centers about 24 inches apart, which matches a natural walking stride; lay a garden hose along the route, walk it normally, and mark where your feet land. That trick sizes the whole order: measure the path, divide by two feet, and that is your stone count. A 40 foot path needs about 20 steppers. Add two or three extra for culls and future swaps.
Setting them so they stay put
The method is simple and worth doing properly. Cut around each stone's footprint, remove the sod, and dig about an inch deeper than the stone's thickness. Bed the stone on an inch of packed sand or stone dust so the top sits flush with the lawn, or a hair above it. Flush stones mow over cleanly and never trip anyone. Step on every corner before you move on; a stone that rocks now will rock forever. No mortar, no concrete, and any stone can be lifted and re-bedded in ten minutes if a root ever pushes it.
Why limestone for paths
Among the stone families we stock, limestone earns the walkway job on grip and temper. Its surface stays matte and slightly toothy rather than polishing slick, which matters on a shaded north-side path that holds morning dew. It handles Arkansas freeze-thaw cycles without shaling apart. And its quiet color range, cream, buff, soft gray, lets a path recede into the landscape instead of shouting at it. If you are weighing it against the warmer browns of sandstone, our sandstone vs limestone guide lays out the differences honestly.
Picking steppers is also simply a pleasant hour. Buyers have been walking this ground and flipping stones since the Bennett Brothers of Hot Springs days, a heritage that goes back to 1972, and the good stones still go to the people who show up and look.
Frequently asked questions
How thick should flat limestone rocks be for a walkway?
Set in soil, 1.5 to 2.5 inches. Thinner cracks over voids; thicker just adds weight without adding life. Consistent thickness across each stone matters as much as the number.
How many steppers do I need?
Measure the path in feet and divide by two, since stones set about 24 inches center to center. A 30 foot path is roughly 15 stones. Add a couple of spares.
Do I need mortar or concrete under stepping stones?
You do not. An inch of packed sand or stone dust in a cut-out bed holds a properly sized stepper for decades, and it stays repairable. Save mortar for walls and mortared patios.
Can I pick out my own stones?
Please do. Walk the yard at 5643 N Hwy 7 in Hot Springs Village and choose every stepper by hand, or call 501-532-1905 with your path length and we will pull a consistent set for pickup or delivery.
