There being so many different shapes to these spaces is another reason why a satisfactory “automatic” system of spacing has not been possible.
Another element to be considered in spacing is the character of the adjoining strokes. for example, in the combination HI two heavy straight strokes come together; in NM two light strokes adjoin; in IM a heavy and a light stroke adjoin; DO, two heavy curved strokes; ON, a curved and a light stroke; DI, curved and straight heavy stroke; and there are numerous other combinations of strokes.
Two heavy strokes must be spaced farther apart then two light strokes, which in turn must be closer spaced than a light and heavy stroke.
The shapes and positions of the adjoining strokes must also be considered. Note these examples: JUJ; LAL; LIL; AVR; CVC; IEX; KXE; OPO; TVA; YVZ.__ It will be observed that the relative position of the strokes is an important ‘factor. It is obvious that the “J and U” must be spaced farther apart than the “U and J”; same with the LA and AL, and so on, because of the difference in the shapes and positions of the various adjoining strokes.
Finally, each factor controlling the spacing is not considered individually. But the eye instinctively takes all these factors into consideration at a glance. The space between the letters of a word is determined by the placing of the first two letters. After that each letter must be blocked in lightly in pencil at such a space from the preceding letter as will “balance” with the preceding space.
The importance of correct spacing must not be underestimated. The effect of good lettering may be injured by poor spacing.
