In base sizing, what is the 1X base equal to?

• A. Tools diameter
• B. Two diameters
• C. One and a half diameters
• D. Half a diameter

Answer: (A)

In base sizing, the unit you use to size everything is tied directly to the tool’s width. A 1X base is defined as exactly the diameter of the tool being used. This keeps measurements proportional and consistent across tools of different sizes. If you used less than the full diameter, or more than the full diameter, you’d be drifting away from that standard unit, which would lead to mismatches in sizing. So the 1X base corresponds to the tool’s diameter.
