Narrative:

Taxiing out on taxiway B at sfo we were told to taxi to the south run-up pad. Shortly after turning east into the pad the first officer said we have crossed the hold short line. Fortunately runway 1L at sfo is only used for departures so no harm was done. We repositioned onto the very small run-up pad without any more problems. How I missed the hold short line while positioning I will never know. I assumed I had more room to position.
