Even spacing, every mark worked out.
Plan evenly spaced pickets, balusters, hooks, brackets, slats, shelves, lights, and frames. Enter the span, the width of each piece, and how many there are. Interval gives you the gap and every mark.

How it works
- 01
Span, width, count
Enter the measured span, the object width, and the number of objects. Interval calculates the gap.
- 02
Every mark position
Get each mark measured from the same starting point, so errors do not add up along the wall.
- 03
Equal or flush ends
Leave a full gap at each end, or start and finish flush with the edges.
- 04
Centerlines or left edges
Mark the center of each piece or its left edge, whichever suits how you hang it.
- 05
Scaled diagram
Check the arrangement on a drawing to scale before you mark anything.
- 06
Tape-friendly units
Imperial or metric. Inch results use tape-measure fractions, with decimals when you need them.
Interval tells you why.
If the pieces cannot fit in the span, you get the reason instead of a layout that fails on the wall.
