What does 'standard size' mean for these bearings?

Standard size bearings are intended for use with a crankshaft that has not been machined or worn beyond its original factory specifications. If your crankshaft has been ground undersize, you would need to select a different bearing size.

Why are these bearings 0.001" thinner than stock?

This slight reduction in thickness can provide a bit of extra clearance in the main bearing journals. This is often beneficial in performance engine builds where tighter tolerances might be a concern, or to compensate for minor variations.

What is the tri-metal overlay mentioned?

The tri-metal overlay is a common feature in high-performance engine bearings. It typically consists of a steel backing, a middle layer of aluminum alloy, and a thin top layer of babbitt (a soft metal alloy) to provide excellent wear resistance and conformability to the crankshaft.
