## What is Baluster Spacing Calculator?

Instantly calculate baluster spacing, gaps, and centres for any railing, deck, fence, or staircase project. Whether you're a professional builder, carpenter, or a DIY enthusiast — this app eliminates guesswork and saves you hours of manual math on the job site.

BALUSTER SPACING CALCULATOR
Enter your total length, baluster width, and maximum gap size — the app instantly calculates the exact number of balusters, centre-to-centre spacing, and gap sizes. Choose from three end baluster options (No Ends, One End, Both Ends) and switch between Max Gaps and Max Centres modes to match your project requirements.

Works with angled installations too. Set any angle from 0° to 60° and get precise angled centres, gap sizes, rise, infill offset, and total infill length — all calculated automatically.

PANEL CALCULATOR
Planning panels between end posts? Enter the length between posts, baluster width, and desired gap size to calculate how many balusters you need, the exact end gaps, and whether end balusters need trimming. The app suggests equal-gap alternatives so you can pick the cleanest layout with one tap.

INTERACTIVE DIAGRAMS
Every calculation comes with a detailed, color-coded diagram that updates in real time. Pinch to zoom and drag to pan — inspect every dimension up close. Angled installations include a separate infill diagram showing the parallelogram shape, offset, and internal angles.

RUNNING MEASUREMENTS
Get a complete list of running measurements from Near Side, Centre, or Far Side — ready to mark out directly on your workpiece. No more adding up numbers with a pencil and paper.
