Thought so, too. First.

The dimensions of such displays are around 7.4mm wide by some 9mm high,
which will equal about .3" wide. Hence, 5 digits need 1.5" of space,
which is 50% off the intended specs.
The trouble is: these are the smallest sizes you will ordinarily find
(try starting at the link below for similar results, LED chips are made
three stories below my office). However, custom designs are possible,
and the actual chips alone are only about .25mm cube. Yes, 250um
(micrometers).
Custom design usually depends on volume ordered. How many digits do you
need? ;-)
Seriously: if anything fits the bill, it will probably have a digit
height of 5mm.
Gene, if you need mechanical specs, there are PDFs for download at our
Web site (only for real products, of course). These contain exact
physical dimensions.
