jsc models
Question???? and yes its probaly obvious to some but not me.I like the JSC ship range but dont like their 1;400 scale.I take their kits which are printed on a4 card and blow them up to a3 size to give a larger model.This seems like a dumb question but if the ship kits are 1;400 scale what are they when i print them out at a3 size.This is genuine question from someone having a maths black out.Help !!!!
currently building jsc uss iowa -at a3 size schreiber 1;200 bremen air daves fat albert hercules blown up to a3 size

Heres my undrestanding...
A3 sheet is two sheets of A4...so thats two times the size or 200% larger? No, not really. Its about 150% enlargement. I will have to check the actual page measures to be sure. Rotate a single A4 page and measure the sides. Compare that to the A4 measure. Looks like about 1 and 1/2 times the length on each side. 150% If you rotated and printed your A4 pages onto A3 pages... and assuming the printer enlargement was a straightforward enlargement based on page size... with no "fit to page" or scaling adjustment... then the final output is 150% of the original. ............. okay, I just checked... you are enlarging from 210mm x 297mm to 297mm x 420mm which is 141% enlargment. So...1:400 becomes about 1:284 scale? or, am I totally lost?

I use 150% as my rough rule of thumb too...is close enough for me i.e. 1/50 to 1/35, 1/72 to 1/48, 1/48 to 1/32 etc...if you are thinking of enlarging 1/100 to 1/72, then 139% is about right...

What I would do, and its a little more complicated, is print one A4 and one A3.
Measure a part on the known kit scale, then measure the same part on the new print. Then calculate how much larger the new print is, and this would allow you to get a good scale of the new print. Caveat - this is assuming the original kit scale is correct.

Yeah, but if your printing method is a standard conversion of A4 to A3
then it would already be based on preset dimensions. And that means a specific percentage enlargement. This specific percentage (that I established as 141%) can be applied to the existing scale to give you the enlarged scale. Which is exactly what Ray is describing....but without having to print two pages. What Ray is indirectly suggesting is we can assume that the original model may not be accurate (to scale) ...so we will need to verify the new scale with some basic measures. And just in case the preset enlargement options associated with your printer are not consistent with a preset A4-A3 dimensional enlargement...you will need to "print it out, then measure it...to find out!" lol is that what you are saying Ray?

Yup. I am a scale modeler, and if I build in 1/144, or 1/32, then I want to verify the measurements of the kit I start with vs a scale drawing of the original vehicle.
