How accurate is the shopping list?

The shopping list is highly accurate, but we recommend double-checking it against your specific project. Here are a few details to keep in mind to ensure everything aligns with your needs:

The tool calculates for continuous railing runs, so additional posts may be necessary for separate sections.

It assumes one set of stairs with railing on both sides and no shared posts between horizontal and stair sections.

You can adjust the post count based on your unique layout.

How do I move forward with a railing project after using the tool?

Once you've completed your design, you can use the Where to Buy or Find a Builder features to connect with local retailers or professionals to bring your project to life.
