What is the typical sterile field border size to maintain during sterile technique?

Explanation:
Maintaining a sterile field relies on a protective non-sterile margin around it to prevent contamination. The typical border size is one inch. This buffer keeps hands, instruments, and drapes from reaching the sterile area and reduces the chance that edge contact will introduce microbes. Anything that touches or lies beyond that border is not considered sterile, so items are kept well inside the border. A border of two inches would waste usable sterile area, a half inch is too small to provide a reliable barrier, and three inches is unnecessarily large.
