Nobody ever compliments a well-built step. That's how you know it was built right. A step gets noticed for exactly one reason — because something is wrong with it — and the noticing is done by your feet, not your eyes. Your eyes forgive almost anything. Your feet forgive nothing, and they keep books.
Here's the proof. Walk any flight of stairs twice and your body has already memorized it. By the second step, your legs have decided what a step is, and they will bet your safety on that decision in the dark, with an armload of groceries, for the next thirty years. One odd riser in the middle of the run and that flight will clip your toe every year for the rest of its life. The stone doesn't wear out. The mistake doesn't either.
The math
Outdoors, no riser taller than seven inches should ever leave the yard. Six and a half is kinder, and six is what you'd build for your own mother. Then the old rule: twice the riser plus the tread should land near twenty-six inches. Inside a house it's twenty-five; outside, your stride opens up, so the steps stretch to match. A six-and-a-half-inch riser wants a thirteen-inch tread. A six-inch riser wants fourteen. Garden steps should feel like a hillside that happens to be made of stone — you climb them without ever deciding to.
The eighth-inch religion
Code allows the risers in a flight to vary by three-eighths of an inch. Your ankles have never read the code. Hold a flight to an eighth, and know that the errors worth hunting hide at the ends — the first riser and the last, where a path or a lawn meets the stone and the finish grade drifted an inch since the drawings. Get those two wrong and the whole flight feels wrong, and no one, including you, will be able to say why.
The tape measure is how you check a flight. It isn't how you accept one. Walk the finished flight — down and back, eyes up, hands full of nothing, thinking about something else on purpose. If your feet don't mention it, it passes.
What's under it
Steps never fail from the top. They fail from below — and in Colorado, below means frost. Water gets under a stone, freezes, and lifts it a quarter inch a winter until your even flight is a xylophone. So the invisible work is most of the work: dig to undisturbed soil, build back up with road base compacted in thin lifts, and set full-thickness stone treads — three inches of sandstone, not a veneer glued to hope.
Two details finish the job. Every tread gets pitched forward about an eighth of an inch per foot — enough that water leaves and ice never gets a lease, not enough that anyone feels the slope. And when the heights don't work out, you cut the stone. You never stack mortar to make up the difference. Mortar shims are a promissory note, and winter always collects.
Steps should arrive somewhere
One last rule, and it's as much design as masonry: never build a single step. A lone step in a path is a trip wire with good intentions — nobody expects it, so nobody's feet are ready. Group them, two or three at a time, and give long slopes room to breathe: three steps, a stretch of path, three more. Landings are punctuation. A flight without them is a sentence nobody can read aloud.
The perfect step is the one nobody remembers climbing.
You reach the top of a good flight thinking about dinner, because your body trusted the ground the whole way up. That trust is the actual product. The stone is just how it gets written down.
