Pencil Techniques

The best pencil for lettering on most surfaces are the H, F, and HB grades.Hold your pencil in the position shown. It should make approximately a 60o angle with the paper.

Freehand Lettering

Developing good lettering is a personal skill which takes practice. Letters must be formed properly.

They must be open shaped very legible.

Clear communication is essential to avoid mistakes and reduce waste.Lettering may be done using a drafting type pencil, lead holder or technical pen. Which ever tool is used, the letters must properly formed and very black

Freehand Lettering

Pull the pencil or pen across the paper. All lettering strokes should be a pulling motion.

Right-handed and left-handed drafters may have to develop different styles for forming letters.

Press down hard when using a pencil.

Freehand Lettering

Vertical capital letters are preferred for most technical work. They are formed within a 6 by 6 grid.

Straight Line letters

Most letters are slightly narrower than they are tall. The shapes of the letters are as open as possible. Letters with small loops and crossing strokes are avoided

Straight Line letters

This sequence is recommended to assure that each letter is the correct width in relation in height. For example, form the two vertical sides of the “H”, “N” and “M” first. Form the top of the “T” first.

Straight Line letters

The “H” and “N” are slightly narrower than they are tall.

The “T” and the “M” are just as wide as they are tall

Note: Proportion: width vs. height is very important in forming letters.

Lettering

The style of engineering lettering we will use in this course is Single Stroke Gothic Lettering Notice that only capital letters are

demonstrated, since we will use only capital letters on drawings
