WHAT IS LETTERING
Writing of titles, dimensions, notes and other important particulars on a drawing is called lettering. Important part of a drawing.It should be clear, legible and uniform in its style.It should be in plain and simple style so that it could be done free hand and speedily.
Ar. Hena Tiwari,GCAD,Sonipat
Lettering is generally done in capital letters.
Different sizes of letters are used for
different purpose
The main titles are generally written in 6mm
to 8mm sizes.
Subtitles are written in 3mm to 5mm sizes.
The drawing number in the title box is
written in numerical of 10mm to 12mm size.
Ar. Hena Tiwari,GCAD,Sonipat
The width of majority of letters is equal to the
height.
All letters should be uniform in shape, slope,
size and shading.
H or HB grade of pencil is recommended for
lettering.
Lettering, except for the dimension figures,
should be underlined to make them more
prominent.

TYPES OF LETTERING
Single stroke letters
Gothic letters

Single stroke letters:
Bureau of Indian Standards recommends
single stroke lettering for use in drawings.
These are the simplest form of letters.
Single stroke means that the thickness of
the line of the letter should be such as is
obtained in one stroke of pencil.
Ar. Hena Tiwari,GCAD,Sonipat
Horizontal lines of letters should be drawn
from left to right and vertical lines ,from
drawn from top to bottom.
Single stroke letters are of TWO types:
Vertical
Inclined

Pencil TechniquesThe best pencil for
lettering on most surfaces are the H, 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 and very legible.
Pull the pencil or pen across the paper.
All lettering strokes should be a pulling
motion.
Press down hard when using a pencil.
Ar. Hena Tiwari,GCAD,Sonipat
Architectural hand lettering is done in pencil,
using light "guidelines", and there are some
important rules to follow.
Good architectural lettering does not go
above or below the guidelines, and the letters
are all uniform in shape and size.
Good and bad examples are shown below:

Vertical capital letters are preferred for most technical work. They are formed within a 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
Ar. Hena Tiwari,GCAD,Sonipat
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.
Ar. Hena Tiwari,GCAD,Sonipat
The “H” and “N” are slightly narrower
than they are tall.
The “T” and the“M” are just as
wide as they are tallNote: Proportion: width vs.height is very important in forming letters.

Single Stroke Gothic Lettering
Procedure: STRAIGHT LETTERS & NUMERALS
Step-1 First draw two horizontal lines of any
length at the distance 10 mm apart from each
other.
Step-2 Then draw vertical lines between the
two horizontal lines at distance 10 mm apart
form each other.
Ar. Hena Tiwari,GCAD,Sonipat
Step-3 Then write down the Capital Alphabet
letters within each box in such a way that
each letter of the alphabet should touch the
boundary of the respective box only. Like in
the same way write down full ABCD….
Step-4 As per the procedure described above
write down numerals from 1 to 0 in a new
line.
Procedure: INCLINED LETTERS & NUMERALS
Step-1 First draw two horizontal lines of any
length at the distance 10 mm apart from each
other.
Step-2 Then draw vertical lines between the
two horizontal lines such that each vertical line
should be inclined at an angle of 75° with the
horizontal line & each line should be at the
distance of 10 mm apart from each other.
Step-3 Then write down the Capital Alphabet
letters within each box in such a way that
each letter of the alphabet should touch the
boundary of the respective box only. Like in
the same way write down full ABCD….
Step-4 As per the procedure described above
write down numerals from 1 to 0 in a new line.

How To Draw Graph For Lettering
The letters are drawn in a graph. Before drawing
the alphabets or numerals of 7:4, 5:4 or any
other ratio, a graph is needed.
First of all take the height of the lettering and
draw two parallel horizontal lines.
Draw the vertical line for making lines for
making squares and inclined line at an angle
of 75′ for making graph for inclined letters.
