Winder Stairs vs. Landing Stairs: Which Should You Choose?
Compare winder stairs and traditional landing stairs to determine which is better for your project. We cover space requirements, building code differences, construction complexity, and cost considerations.
When a staircase needs to change direction, you have two main options: a flat landing or winder treads. Each has distinct advantages depending on your space and priorities.
What Are Winder Stairs?
Winder stairs use wedge-shaped treads to turn a corner instead of a flat landing platform. The treads "wind" around the turn, allowing continuous stepping through the direction change.
Common Configurations
- 90° L-shaped winder: Three winder treads replace a quarter-turn landing
- 180° U-shaped winder: Six winder treads replace a half-turn landing
- Combination: Winders at one turn, landing at another
What Are Landing Stairs?
Landing stairs use a flat platform (at least 36" × 36") at the turn point. The walker stops climbing, crosses the flat landing, then continues in the new direction.
Side-by-Side Comparison
| Factor | Winder Stairs | Landing Stairs |
|---|---|---|
| Space needed | Less (no flat platform) | More (requires landing area) |
| Comfort | Moderate | High (rest point at landing) |
| Safety | Good if code-compliant | Better (flat rest area) |
| Construction | More complex | Simpler |
| Cost | Higher (custom treads) | Lower (standard framing) |
| Code complexity | Stricter requirements | Standard requirements |
| Moving furniture | Harder | Easier |
Building Code Requirements for Winders
The IRC (Section R311.7.5.3) has specific rules for winder treads:
- Minimum tread depth at the walk line (12" from narrow end): 10 inches
- Minimum tread depth at the narrow end: 6 inches
- Winder treads must meet standard riser height limits (max 7¾")
When to Choose Winder Stairs
- Tight spaces: You need every inch of floor area
- Continuous flow: You want an uninterrupted climb
- Visual appeal: Winders can look elegant and streamlined
- Renovation: Fitting stairs into an existing footprint
When to Choose Landing Stairs
- Primary staircase: Used multiple times daily by all household members
- Accessibility: Users who need a rest point while climbing
- Furniture moving: You'll need to move large items between floors
- Simpler construction: You want straightforward framing
- Budget: Standard lumber and standard cuts
Construction Complexity
Winder stairs require:
- Custom-cut wedge-shaped treads
- Careful stringer layout with compound angles
- Precise tread depth verification at multiple points
- Additional framing support at the turn
Landing stairs require:
- Standard stringer cuts (two sets)
- A flat platform framed like a small floor section
- Standard tread installation
Cost Comparison
For a typical residential L-shaped staircase:
- Winder version: $3,000 – $6,000 (custom treads and complex framing)
- Landing version: $2,000 – $4,000 (standard framing and materials)
The premium for winders is primarily labor cost, as the framing and cutting are more time-consuming.
The Bottom Line
If space is your primary constraint, winder stairs are the clear winner. If comfort, safety, and simplicity matter more, go with a landing. Many modern homes use a combination - winders where space is tight, landings where there's room.
