Railing Post and Picket Calculator

Enter railing length and height and see posts, pickets and rail lengths to plan for.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual metal, thickness, access, local rules and conditions. Only a visit can confirm what a job needs, and we give you a clear price before any work begins.

Questions

About this tool.

Is this a design?

No. It is a planning guide. Railings are safety items, and rules for height, spacing and strength vary by location.

What gap should I use?

Local rules set a maximum opening. Enter the number you must meet and the tool counts balusters to suit.

Does it count stairs?

Stair runs are estimated from the length along the slope. We measure on site.
