A normal PR interval measures 0.12-0.20 seconds which is 3 to 5 small boxes on the EKG strip. When you measure a PR interval, you start measuring at the BEGINNING of the p-wave until the BEGINNING of the QRS complex. Here are some simple steps on how to measure the PR interval: Find the P-wave on the EKG strip. Determine where the PR interval is, and to do this you start measuring at the beginning of the p-wave until the beginning of the QRS complex. Count the SMALL boxes between there measurements. Remember each box represents 0.04 seconds.
