LANCE FIELD GUIDE

How to Choose a Straight Edge

Straight edges support measuring, marking, drawing, and layout. Choose by unit system, backing, calibrated edge, width, length, and working context.

Units, length and backing.

  • Choose inches, centimeters or a dual scale to match your work.
  • Choose a length that spans the line you need to measure or draw.
  • Keep the ruler supported by the work surface.
  • Choose slip-resistant backing when you need more grip.
