Are Door Knobs Universal In Size, Or Do I Need To Measure Before Installation?
In Denver County, Colorado, property owners often ask whether door knobs are universal in size or if doors need to be measured before installation. While many knobs are designed to fit standard openings, not all doors are built the same. Measuring first ensures that your new hardware fits properly and avoids complications during installation. For homes and businesses in Denver County, this step can prevent unnecessary delays and extra costs.
Understanding Door Knob Sizes and Measurements
Standard door knobs are typically made for bore holes that are 2 1/8 inches wide, with a latch hole of 1 inch. The backset—the distance from the door edge to the knob center—is usually 2 3/8 or 2 3/4 inches. In Denver County, older or custom doors may have different measurements that don’t fit standard knobs. Measuring before buying ensures a proper match and prevents issues like knobs that don’t latch or sit unevenly. When the right size is chosen, installation is faster and more secure.
Door thickness also affects installation in Denver County, Colorado. Most knobs work with doors between 1 3/8 and 1 3/4 inches thick, but adjustments may be needed for other sizes. Professional installers use the correct tools to align hardware and ensure smooth function. This avoids common problems such as loose knobs or sticking latches. Taking measurements first—or relying on expert help—ensures your new knob looks great and performs reliably.
