I'm building an Eagle component for an LSM115J.
The connectors on this part have fairly large tolerances (1.85-2.21mm width, 0.76-1.52mm length). There is no recommended land pattern.
Should I go for the largest size (so the part will never need to be partially soldered on top of the stop mask), the smallest size (so the part has a well-defined placement) or something in the middle?

That package is an SMB. Here is Diodes Inc. suggested footprint for their SMB (almost the same):
The IPC footprint expert would give you a somewhat different footprint (more prone to shorting in the center IMO).
