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 |

I think the scale on the A4 paper on the A3 paper will be 1: 53.75. A3 is 1.414 times as large as A4 and 1:76 divide by 1.414 is 1: 53.74823197 so actually 1: 53.75.

Actually I think Berry is spot on there.
Actually, Owen, there could be a slight variation as well due to margin and "white" space settings. If you have access to a copier, copy an item at A4. Then enlarge to A3. compare the measurement of the two and you can then work out the scale. Don't worry about splitting hairs. If you wanted 1/35 and you got 1/38 so what? And visa Versa?

*the enlargement applies to each linear dimension, therefore a two-dimensional A2 sheet covers either two (not 1.4142) A3s or four (not two) A4s |
