Let’s cover technical drawing paper sizes and how to fold technical drawing paper.
Standard paper sizes are specified in TS 8 8/1 (Turkish Standard). A-series sheets are used in technical drawing. The largest, the A0 sheet, has an area of 1 m2, and its side ratio is 1:2.
It’s rectangular in shape. All A0 sheets have the same ratio. The other sizes are made by halving the long side.
Technical Drawing Paper Sizes – A Series
The A1 size is obtained by halving the long side of the A0 size. The A2 size is obtained by halving the long side of the A1 size. A3, A4, and A5 are made the same way, by halving the long side each time.
Margins for protection should be given on transparent tracing paper that needs to be kept and archived.

A0 paper dimensions: 841 mm X 1189 mm
A1 paper dimensions: 594 mm X 841 mm
A2 paper dimensions: 420 mm X 594 mm
A3 paper dimensions: 297 mm X 420 mm
A4 paper dimensions: 210 mm X 297 mm
A5 paper dimensions: 148 mm X 210 mm
Title Block Areas on Technical Drawing Paper
Although there are various versions of title block areas on technical drawing paper, these have been standardized by the Turkish Standards Institution (TSE). Even so, businesses can make whatever changes and adjustments they see fit to suit their own needs.

How to Fold A0, A1, A2, and A3 Paper
Sheets larger than A4 are folded for filing purposes. This folding follows certain rules. When technical drawing paper is folded and filed, it needs to end up at A4 size.
For sheets larger than A4, starting from the right edge, you fold leftward in 190 mm increments. When it meets the filing-margin line, it should measure 190 + 20 mm = 210 mm.
Vertically, it’s folded in half after 297 mm, or into 3 for the A0 size.
On the A2, A1, and A0 sizes, the top-left corner is folded into a triangle shape from 105 mm to 297 mm. This is done so these files can be opened easily.
For the paper to be folded easily and quickly, a line should be marked every 190 mm along the bottom edge.
