STRAIGHT STAIR · GEOMETRY PLANNER
Check your proposed stair layout
Enter the finished rise, your riser count and the going. Review what the geometry says, then bring the unresolved authority and structural questions to the right professional.

YOUR PROPOSED LAYOUT
Geometry first, authority questions separate
The results describe the endpoints shown below. They do not specify a buildable stair or a structural member.
STEP 1 · MEASURE
Finished floor-to-floor rise
Measure vertically from the lower finished floor to the upper finished floor or landing. Do not use rough framing height.
STEP 2 · PROPOSE A LAYOUT
Check my proposed layout
You choose the riser count and the horizontal going. PlanHousin does not choose a code or recommend a design.
If your layout uses a flush top tread, separate top platform, winders, a turn or unequal rises, this configuration is outside this planner’s scope.
Compare with my measured available run (optional)
Landing space is excluded. This comparison does not approve a stair.
Example geometry — not a construction recommendation.
STEP 3 · OPTIONAL AUTHORITY INPUT
Compare only provided constraints
No universal limits are preloaded. Enter one identified source and the particular limits you want compared. This is not a code-compliance or structural check.
PROJECT SHEET
Geometry and questions to resolve
For discussion with your local authority or qualified designer. Not a construction plan.
