Stair Stringer guide
Stair Stringer: Printable Job-Sheet Workflow
The stair stringer job sheet preserves the measured inputs, riser count = ceiling(total rise ÷ target riser), the unrounded result, the issued field value, and the source checked at the time of release. A project identifier, author, review date, and revision state prevent an older calculation from remaining in use after conditions change.

A stair stringer sheet is a cut-member layout, not a complete circulation plan. It preserves the plumb cut, seat cut, tread line, riser line, throat depth, bearing point, finish-floor correction, and stringer stock size on one drawing. Lumber defects, wane, knots, crown, kerf direction, support locations, fastening, and the sequence of test cuts matter because a geometrically correct rise-and-run pattern can still leave an unsafe or unusable member. The field check therefore concentrates on how the notch pattern changes the remaining wood and how the cut stringer lands on its upper and lower supports.
The issued sheet carries a project identifier, author, date, revision mark, input list, formula, unrounded result, practical issued value, and checked source. Superseded copies are removed from the work area, and any field change that alters an input creates a new calculation rather than a handwritten change to the final number.
- Attach the printable reference at /charts/stair-stringer-template to the calculation record.
- Show inputs with units, formula, unrounded result, issued result, and source.
- Remove superseded sheets from the work area when a revision is released.
For this tool, the calculation method is riser count = ceiling(total rise ÷ target riser). The consolidated page keeps this topic beside the worked method, material checks, source boundary, and printable record.
