Bolt Hole Line Calculator

Calculate X/Y coordinates for evenly spaced holes along a straight line between two points. Enter start and end coordinates with the number of holes.

Start X

Start Y

End X

End Y

Number of Holes

Formula:
Total Length = sqrt((X2-X1)² + (Y2-Y1)²)
Spacing = Total Length / (N - 1)
Each hole position is linearly interpolated between the start and end points.

Why Linear Hole Patterns Matter

Linear hole patterns — evenly spaced holes along a straight line — are one of the most common features in fixture plates, rails, and mounting brackets. This calculator gives you exact coordinates so you can program them directly without manual math.

Eliminates pitch accumulation errors that compound across many holes
Handles angled lines, not just horizontal or vertical — useful for inclined mounting surfaces
Outputs coordinates ready for G-code absolute positioning or DXF import
