The 45% rule is that to look right, the engraving should be 45% of the height of the piece.
If you want three lines with the top one 1.5 X the height of the others you can use a formula. Difficult to explain so I will try to give an example.
The piece will be 2.5" tall in the example.
2.5" X .45 = 1.125" total engraving height
First line 1.5 X the next two. 1.5 + 1 + 1 =3.5
1.125 / 3.5 = .321
The bottom two lines (1 X) should be .321" tall
The top line at 1.5 X the others should be .321 X 1.5 = .482
As far as the left and right margins .08 X Width usually works, especially on smaller pieces. On larger pieces .06 works well. New Hermes Gravograph 98 defaults to .10, way too large except for tiny pieces. Dahlgren used .08.
