I stand corrected. A slightly more accurate measurement gives pins within a row
at 2.75+/-0.01 mm, between rows 3.00+/-0.10 mm (the latter more likely to be
less than more).

My mistake arose because the row of 13 pins on a DB25 measures almost exactly
1.3 inches, pin centre to pin centre. How could I do such a thing? There
really is no excuse!
