The big four
- Running length — the most obvious driver, scales roughly linearly
- Grade — 316 costs more than 304 (see our grade guide)
- Finish — PVD colour and specialty textures cost more than standard mill finish
- System type — glass infill costs more than simple bar balusters due to the glass and hardware
Factors people forget to budget for
- Design complexity — curves, custom patterns and decorative panels take more fabrication time than straight runs
- Site access — difficult installation access (tight staircases, high floors) adds labour time
- Number of posts/newels — more turns and landings mean more heavy anchor points, not just more length
Getting an accurate estimate
Share approximate running length, number of turns/landings, and your finish preference upfront — this alone gets you a far more accurate number than "how much for a railing" without detail. See our railing design guide for the fuller brief checklist.
