Stair Rise and Run Code Chart
The Stair Rise and Run Code Chart provides a complete, printable HTML lookup table with the values shown below. Every row is present in the served page source, so the numbers remain readable without JavaScript. Use direct conversion rows as written; for structural rows, confirm the cited source, material species, grade, loads, spacing, and local requirements.
| Item | Planning value | Source reference | Field note |
|---|---|---|---|
| Maximum riser | 7 3/4 in | IRC R311.7.5.1 | Measure vertically between adjacent tread nosings. |
| Minimum tread depth | 10 in | IRC R311.7.5.2 | Measure horizontally between nosings. |

Frequently asked questions
Can I print the stair rise and run code?
Yes. Use the Letter or A4 PDF links, or print the HTML table directly. The printable view removes navigation and keeps the title, table, source note, and brand.
Is the table available without JavaScript?
Yes. Every row is rendered as ordinary HTML with a caption and scoped headers. JavaScript is not required to read or quote the values.
Can I use the values as a final structural design?
No. Conversion charts are direct references, but span and member-size charts are planning examples. Current code tables, species, grade, loads, connections, and professional review govern structural work.
How often is the chart reviewed?
The review date is shown on the page and in the Dataset schema. Source-linked code tables are checked when their governing publication changes.
