I have a Craftsman's Tablesaw, circa 1950, and want to build a full
size
(use both miter slots) crosscut sled for it. The tabletop measures
21" W x 27" D. I intend to make it 24" deep but was wondering if
there is a "rule of thumb" for the width?

Try 25" x 48".

Go to library and get Fred Bingham's book, "Practical Yacht Joinery".

Covers the subject in detail.

He calls it a SLAT, but NBD, it's still a SLED.

You will build several different ones, trust me.

Good luck.
