Baluster Studio
Railing spacing calculator
Free · In-App Purchases
Baluster Studio is a field-ready layout aid for railing fabricators, deck builders, and finish carpenters. Enter the inside run, post width, baluster width, and code rule. Baluster Studio calculates the baluster count, clear spacing, on-center layout, and pass/fail status before you cut.
Built for real railing work:
- Flat railing and stair-rake layout support
- IRC 2021 R312.1.3 and R311.7.8.1 code citations
- 25 standard baluster styles plus custom dimensions
- Quick Calc for one-off field checks
- Local project job book for clients, addresses, and sections
- Tape reads and material counts for site work
- PDF export with drawings, notes, bill of materials, and disclaimers
- Contractor branding for PDF packets
- Worksite Mode for bright, always-awake field use
Baluster Studio works fully offline. There is no account, no cloud sync, and no analytics. Projects stay on your iPhone or iPad unless you export them.
Baluster Studio is a layout aid, not stamped construction drawings. Always verify measurements on site and against the code edition adopted in your jurisdiction.
