What is the size of long coupon bond in centimeters?

The size of a long coupon bond itself is not standardized in physical dimensions like centimeters, as bonds are typically issued in digital format rather than as physical certificates. However, when issued as physical certificates, they can vary in size, often resembling standard paper sizes such as A4 or letter size, which are approximately 21 x 29.7 cm or 21.6 x 27.9 cm, respectively. The actual dimensions may differ based on the issuing entity's design and preferences.
