Geometry and layout calculator
Equal Hole Spacing Calculator
Find the center location of every hole across a measured length, with optional hole diameter and edge distances.
What the result means
Center spacing is measured from the center of one hole to the center of the next. Five holes create four spaces between their centers.
Formula
Center spacing equals the distance between the first and last hole centers divided by one less than the number of holes.
Common mistakes
- Counting five holes as five spaces.
- Measuring each hole from the previous hole.
- Confusing center spacing with the clear material between hole edges.
