Words which begin or end with A Y L V W T may need spaces a little less than those with H I M, etc. In small types the inequalities in white space beside or between combinations like L Y A T W and letters with regular shape like H I M N, may not be readily noticed, but in large sizes of capitals these differences are greatly increased and will often make unequal white spaces in a line with uniform metal spaces. In some styles of types a line may need unequal metal spaces in order to space the words evenly.

This line has en-quads between the words, but the forms
of L and T make the white space greater than
between the first and second words.
This line has an en-quad in first space and three-to-em
in the second, with hair-spaces between some
letters of the words.
So, also, it will often be necessary to insert pieces of paper, card, or thin leads between the letters of a word in large display, in order to make them evenly spaced, as shown in these examples:
