c. Scalable Fonts. Some software programs include the ability to size

(change the scale) fonts through keyboard controls. With most scalable

fonts, the size you see on the computer screen (monitor) is the same size

as the finished document. This is referred to as "what you see is what

you get" (WYSIWYG). Scalable fonts are normally available with desktop

publishing software such as Ventura.

d. Proportional Fonts. Proportional fonts assign more space to wider

letters than they do to thinner letters. The font this subcourse is

prepared in is courier. Courier is a fixed font, all letters are assigned

the same amount of space.

Appendix C provides a comparison between fixed and proportional fonts.

There are no particular advantages or disadvantages to either fixed or

proportional fonts. The choice is a personal one.

e. Font Sizes. The font sizes used in most computer programs are

expressed in points just as they are in hand and mechanical lettering.

One exception to this is Harvard Graphics. This software program uses

sizes that are expressed as a percentage of the narrowest margin in the

paper size selected. Standard paper is 8 1/2 inches by 11 inches and the

narrowest margin is 8 1/2 inches whether you are printing in the portrait

mode (8 1/2 inches wide by 11 inches high) or the landscape mode (11 wide

by 8 1/2 inches high).

f. In Harvard Graphics, a letter 8 1/2 inches high equals size 100.

In points, this would be 72 points per inch times 8.5 inches or 612

points. The question now is how to convert from points to size and vice

versa. The key to this conversion is percentage. Remember that the size

used in Harvard Graphics represents a percent of the narrowest size of the

paper. Using this information you then can convert from points to size

regardless of the dimensions of the paper you use.

(1) First calculate the number of points contained in the narrowest

dimension of the paper. Example: 8.5 inches multiplied by 72 points per

inch equals 612 points.

(2) Next, divide the height of the desired letter (in points) by the

number of points contained in the narrowest dimension of the paper and

multiply the result by 100 (to convert it to a percent). Round your

answer to one decimal place. In this example, 612 points. If you want to

create a letter 72 points high (1 inch), then divide this number by 612.

The result is .1176. Now multiply this by 100 giving you an answer of

11.76, rounded to one decimal place is 11.8. This is the size you would

enter in Harvard Graphics to create a letter 72 points high.
