## Description

Plan evenly spaced pickets, balusters, hooks, brackets, slats, shelves, lights, and frames with a simple one-line layout tool.

Enter the measured span, object width, and object count. Interval calculates the gap and gives you every mark position from the same starting reference. Compare Equal ends with Flush ends, then use centerlines or left edges to mark the layout.

A scaled diagram makes the arrangement easy to check before you mark. Choose imperial or metric units; inch results use tape-friendly fractions and show calculated decimals when needed.

If the pieces cannot fit in the span, Interval tells you why.
