Interval Live

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.

When it will not fit

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.
