What is the 2 General divisions of letters?

Answer 1

Division of Letters

The two general divisions of letters are Single Stroke letter and outline or single built-up letter

Single Stroke letter:

The term single stroke means that the letters and numerals should be made by uniform thick lines produced by the line width obtained in one stroke of the pencil or pen. This does not mean that the entire letter should be written without lifting the pen or pencil.

The single stoke letters recommended by BIS can be classified into the following categoreies:

1. Vertical (00)
2. Inclined (150 to right)

Classification by height (h) to line thickness (d) ratio:

1. Lettering A (d=h/14)
2. Lettering B (d=h/10)

The size of letters and numerals are designated by their height. The height of the capital letters is taken as the base of the dimensions. Vertical and Inclined Letters: The vertical letters have the stems perpendicular to the base line of lettering But for inclined letters, the stems are inclined at 150 to the right of the vertical drawn perpendicular to the base line

The most basic division in typography is between serif and sans-serif typestyles. A serif typeface has serifs--small lines, flourishes or embellishments on the top and bottom of its characters. Think of Times New Roman--that's a serif font. Sans-serif letters like Helvetica lack these extra strokes on the character. There are several more specific categories within the serif and sans-serif groups. For example, Modern typefaces have a large contrast between thin and thick strokes, and Geometric typefaces have even strokes and large apertures. The aperture is the space within a circle, such as a lower case "a" or "o."

Serif fonts are used mainly in printed documents because the extra stroke allows the word to be seen and read as a unit, rather than as a group of individual letters. This makes for faster and easier reading. However, the resolution on a computer screen is much lower than on a printed page, so serifs can blur and become illegible when viewed on a monitor. According to the Complete Reference Web Design, sans-serif fonts maintain their shape better on screen. For the best legibility, choose a sans-serif typeface for online use and a serif type for printed text.
