This way, you have them to refer to when you check the nitrile gloves size chart. Some brands make only a unisex medical glove size but they offer an extra small size for hands that measure 6 inches. Note: The nitrile glove sizing conventions differ slightly from one manufacturer to another.
When switching brands, it is best that you do not assume you have the same size. If you are in-between sizes, round off to the nearest inch or centimeter.

Moreover, the gap between the glove material and your hand will allow bacteria, air, and harmful chemicals to enter. Not to mention, it will affect the way you hold and control your instruments. On the flip side, wearing tight-fitting gloves will rip the material.
