3. Scope of IS 962 : 1989
This code lays down the recommendation for:
1. Sizes of drawings
2. Layout of drawings
3. Reproduction of drawings
4. Folding of prints
5. Scales
6. Projection
7. Line work
8. Lettering and dimensioning
9. Graphical symbols
10. Abbreviations
11. Conventional Representation of Materials
12. Number of Buildings & Parts of Buildings
13. Designation of Rooms & Other Areas
14. Coloring the Plan

4. Sizes of Drawings:
The original drawing sheet should be made on the smallest sheet permitting the necessity
clarity and resolution.
Table 1: Preferred Sizes
Designation Dimension (mm)
A0 841 X 1189
A1 594 X 841
A2 420 X 594
A3 297 X 420
A4 210 X 297

5. Layout of Drawings:
For details about layout, reference shall be made to IS 10711 : 1983.
Table 2: Drawing Spaces
Recommendations are also provided for revision, numbering of drawing sheets, repetition of drawing numbers and
reproduction of drawing sheets.
Designation Dimension (mm) Drawing Space (mm)
A0 841 X 1189 821 x 1159
A1 594 X 841 574 x 811
A2 420 X 594 400 x 564
A3 297 X 420 277 x 390
A4 210 X 297 180 x 277

7. Scales:
Scale is the amount by which a real object is reduced (or enlarged) to represent it with
accurate size on a drawing sheet.

8. What is x:y?
Think and write the answers in your notebook. You have 2 minutes.
Thought Bubble:
Rohan Dasgupta

9. x:y is a scale where
1 unit of length in real ≡ x/y units of length in drawing
For example, 1:100 is a scale where
1 unit of length in real ≡ 1/100 or 0.001 unit of length in drawing
If the unit of length is metre, then
1 m in real ≡ 0.001 m or 1 cm in drawing

Scale is the amount by which a real object is reduced (or enlarged) to represent it with
accurate size on a drawing sheet.
