Hello,
I have a drawing in A4 format, at a scale of 1:500.
I would like to reproduce it in A3 format, at a scale of 1:200. Also, consider at a scale of 1:100 if it works.
Does anyone know what the enlargement percentage is, please?
Thank you very much,
François

Hi.
When moving from A4 to A3, the ratio is:
[x square root of 2] or [x 1.414]
This applies when moving from A5 to A4, A3 to A2, A2 to A1, or A1 to A0.
For the scale, it’s different:
to go from 1/500 to 1/200 (enlargement), the ratio is:
[500/200] or [x 2.5]
to go from 1/500 to 1/100 (enlargement), the ratio is:
[500/100] or [x 5]
So when moving from A4 to A3, the scale enlargement ratio is:
[500/1.414] or about 1/354.
You can go from 1/500 to 1/200, but you'll be missing some information...
