For plus GP lenses, to position higher, the lens diameter should be:

Lens position with plus GP lenses is influenced by diameter, because the edge of the lens interacts with the eyelids. Increasing the diameter tends to bring more of the lens under the upper eyelid and alters how the lid presses on the edge. This lid-edge interaction tends to push the lens higher on the cornea, producing a higher-fitting position. In contrast, a smaller diameter reduces that lid contact and the lens tends to sit lower. Using the same or a medium diameter won’t actively shift the position. So, choosing a larger diameter is the way to achieve a higher lens position.
