## What is Baluster Spacing Pocket?

Baluster Spacing Pocket is a paid offline field utility for deck builders, trim carpenters, rail installers, remodelers, and serious DIY users who need a clean baluster layout before cutting, drilling, or ordering infill.

Use it to:

- choose a level rail or stair rake layout
- switch between wood, square-metal, stair-wood, and custom baluster presets
- enter clear opening, baluster width, and target maximum opening
- calculate baluster count, equal opening size, on-center spacing, and first and last center marks
- read near, center, and far marks in carpenter-friendly fractions
- add optional unit cost for a quick infill cost check
- share a field-ready layout summary with the full mark list

Why people buy Baluster Spacing Pocket:

- equal spacing errors show up immediately once holes are drilled or rails are assembled
- field crews need a narrow rail-layout tool, not a generic construction calculator
- stair-rake layouts are easy to misread when the math is split between notes, tape, and phone calculator
- paid-once offline workflow is faster than bouncing between spreadsheets and ad-heavy utility apps

Baluster Spacing Pocket works best for:

- deck guardrail baluster layout
- porch and stair rail spacing
- square-metal or wood spindle replacement jobs
- remodel and punch-list rework where one rail bay must be laid out quickly

This app is a planning aid only. It does not provide structural engineering, code compliance approval, permit guidance, stair design certification, or guaranteed local inspection compliance.
