A Question of scale
The old question of scale, I am just being stupid but need help with the following.
I enlarge a lot on my printing of models from A4 sheet size to A3 sheet size. this is an increase of approx 50%, if the original model was, say 1:76 scale on the A4, how do you calculate the scale for the model printed on A3, an increase of approx 50%. If you just decrease the original scale by 50% from 1:76 to 1:38 it is then a decrease of 100% in the scale?????
Help
Regards
Owen
