Railing Run Planner
Enter your railing one post-to-post section at a time and this figures posts, rails, spindles and mounting hardware - stairs included, measured on the slope.
Give each section's length, 8 ft maximum. Tick “stairs” on a sloped section and give run and rise instead. Then pick the rail stock, spindle style and how the rails mount.
Post count, rail sticks with the cuts already packed, spindle counts, brackets, and a priced list you can adjust before it goes to the cart.
Measure the two easy numbers — run flat along the floor and rise straight up — and the tool figures the rail on the slope for you.
Enter each post-to-post section (max 8 ft — that's the post spacing). A corner just shares a post: enter each side as its own section, no extra parts. Tick "stairs" on a section and give run + rise — the tool figures the rail length along the slope, and that section gets 26-inch stair spindles. 3-inch spindles at max 7-inch centers so no gap passes a 4-inch sphere. Local code may differ — we'll confirm by phone before anything ships.

Math, in the open: posts = your sections + 1 (corners share a post — three 8-ft sections straight or around a corner take the same parts) · stair sections figure the rail along the slope: √(run² + rise²) — a flat section is just rise = 0 · rail cuts (top + bottom per section) get packed into the fewest full sticks, largest cuts first, the way a contractor would cut them · spindles = 3″ spindles at max 7″ on-center along the rail, so no gap passes a 4-inch sphere (26″ spindles on stair sections, 29″ on flat) · mounting your way: Ram Tough brackets (2 per rail), the tenon-cutter rental, or your own hardware. Every quantity above is editable before it goes to the cart. Local code may differ — we'll confirm by phone.
