Its a surface mount device, use the recommended footprint is best, the size is going to be so small you would hardly notice. use some other method such as silk, or do what many do and rely on data and pick and place info being correct.
I have never seen anyone do a different pad for an SMD devices pin 1 (PTH, some use a square pad) but for small SMD devices you are best sticking to the recommended pad size.
I would read up on IPC-7351 and "The CAD Library of the Future"
