How to Measure 16 on Center?

Published in Framing Measurements 2 mins read

To measure 16 inches on center (OC), start by establishing your first point and then mark subsequent points every 16 inches from the center of one element to the center of the next. In the context of wall framing, this often means measuring 16 inches from the center of one stud to the center of the next stud.

Detailed Explanation of Measuring 16" OC for Wall Framing

When laying out studs for wall framing at 16 inches on center, it's crucial to be accurate for structural integrity and ease of finishing. Here's how you can accurately measure and mark:

  1. Establish a Starting Point: Begin by marking the location of the first stud. This starting point is essential as all subsequent measurements will be based on it. This measurement should be relative to the edge of your sheathing if applicable.

  2. Measure and Mark: From the center of your first stud location, measure 16 inches and mark the center of the next stud location. In the provided reference material, the example involves a starting measurement of 31 and a quarter inches, followed by 47 and a quarter inches (which is 16 inches from 31 and a quarter).

  3. Repeat: Continue measuring and marking every 16 inches. The key is to consistently measure from the center of one marked location to the center of the next.

  4. Use a Square: After marking, use a square to ensure your lines are perpendicular to the plate or beam, giving an accurate location to place your stud.

Example:

If your first stud is located at the 1-inch mark from the edge, the following studs would be located at:

  • 17 inches (1 + 16)
  • 33 inches (17 + 16)
  • 49 inches (33 + 16)
  • And so on...

Important Considerations:

  • Accuracy is Key: Precision is essential for structural integrity and for attaching sheathing and drywall correctly.
  • Consistency: Always measure from center to center.
  • Adjustments: Be mindful of corners and intersections. You might need to adjust stud spacing slightly to accommodate specific design requirements.
  • Mark clearly: Make distinct marks to avoid confusion during the framing process.
