Cómo Usar Esta Calculadora

1. 1Measure the total rise from finished floor to finished floor in inches.
2. 2Enter the landing depth (minimum 36 inches per IRC, matching stair width).
3. 3Enter the desired tread run per step (10 inches minimum per IRC).
4. 4Click Calculate for total steps, steps per flight, landing height, and total run.

Sobre Este Material

Stair landings are intermediate platforms that break a long staircase into two or more flights. The IRC requires a landing at least as wide as the stairway and at least 36 inches deep in the direction of travel. Landings serve multiple purposes: they provide a rest point on long staircases, allow directional changes (L-shaped and U-shaped stairs), and improve safety by limiting the distance a person could fall. The IRC does not specify a maximum flight height before requiring a landing, but many local codes require a landing when the vertical rise exceeds 12 feet or 147 inches. Landings are framed like small floor sections, using joists, headers, and decking supported by posts or walls. For L-shaped stairs (90-degree turn), the landing is typically a 36x36-inch platform. For U-shaped stairs (180-degree turn), the landing is wider to accommodate the direction reversal — usually 36 inches deep by the combined width of both flights plus the wall between them. Landing framing uses 2x10 or 2x12 joists, supported by a ledger board on one wall and posts or a bearing wall on the open sides. The landing surface matches the tread material: plywood subfloor with carpet or hardwood for interior stairs, or pressure-treated decking for exterior applications. A landing adds $200 to $800 to the staircase material cost, plus $300 to $1,000 in labor for a contractor installation.

Consejos de Instalación

• •Frame the landing as a miniature floor system — use 2x10 or 2x12 joists at 16 inches on center.
• •Secure the landing to adjacent walls with a ledger board using lag bolts or structural screws.
• •Ensure the landing surface is perfectly level — use a 4-foot level in both directions.
• •Match the landing height exactly to the calculated rise of the lower flight to avoid uneven risers.
• •For L-shaped or U-shaped stairs, frame the landing before cutting and installing the upper flight stringers.

Errores Comunes a Evitar

• ⚠Making the landing too shallow — it must be at least 36 inches deep in the direction of travel (IRC R311.7.6).
• ⚠Not treating the landing as a structural element — it needs proper joist framing, not just a sheet of plywood.
• ⚠Unequal riser heights at the landing transition — the riser onto and off the landing must match all other risers.
• ⚠Forgetting to account for landing thickness when calculating flight heights — the landing platform itself has height.
