Trike wing registration letters

[Kingfisher]

Can anyone assist with the normal/average size of the wing registration letters on a windlass wing.
Is there any regulation stating this ?

Yes there are regulations

SA-CATS-ARM and Part 47

Specification of marks
(1) The nationality and registration marks must consist of capital letters in
Roman characters without ornamentation.
(2) The width of each letter (except letter “I”) and the length of the hyphen
must be two-thirds of the height of the letter.
(3) Each letter must be separated from the letter which immediately precedes
or follows it by a space equal to one-third the height of the individual letters,
the hyphen being regarded as a letter for this purpose.
(4) The lines forming the letters and hyphen must be solid and the thickness of
those lines must be one-sixth of the height of the letter.
8. Measurement of marks
(1) The nationality and registration marks must be formed of letters of equal
height, and must be so situated as to leave a margin of at least 50 mm
along each edge of any surface to which they are affixed.
(2) The height of the marks on lighter-than-air aircraft must not be less than
500 mm.
(3) The height of the marks on aeroplanes and gliders must be –
(a) on the wings, not less than 500 mm; and
(b) on the fuselage or equivalent structure and on the vertical surfaces, not
less than 300 mm, except that where the surface is not large enough to
accommodate full-size marks the Commissioner may approve marks
of a lesser measurement provided they are not less than 150 mm in
height and can be readily identified.
(4) The height of the marks on rotorcraft must be –
(a) on the bottom surface of the fuselage or cabin, not less than 500 mm
high; and
