Non-Designer’s Type Book, The, Second Edition

Watch for These Features

Large x-height:	Increase linespacing.
Small x-height:	Decrease linespacing.
Tall ascenders:	You can get away with less linespacing because the x-heights are relatively small, but you might want to actually add dramatic linespace to emphasize the tall ascenders.
Reverse type:	Along with increasing the point size by a point or two and increasing the weight a bit, you should probably also add a tiny bit more linespace.
Long lines:	If you must use long lines of text, add a tiny bit more linespace so the reader can find the beginning of the next line easily.
Wide letter spacing:	If the typeface is set with lots of letter spacing, add more linespace for balance.
