Hello guys!

I have a minor problem....
How do i rescale from 1:35 up to 1:25
I have a freeware model from bestpapermodels.com of a small house i would like to use in a 1:25 diorama
but it is in 1:35...
 
When I rescale I start with the target scale (35), and divide that by the model scale(25). That produces the percentage change to print.
35/25=1.4
that is 140%
Test print a page that has a control part, that is a part that you know the size of. Measure that control part to verify that the scaling is correct. If it is, build away, if not; find the percentage difference of the control part to the prototype. Multiply that percentage to your previous number (in your case the 140%). Print that same page at your new target percentage. Measure the control part. Continue this until you can live with the results.

Remember that scaling up requires larger pages or tiling parts. I try to avoid scaling up more than 300%.

I hope to see the results of your build!

Hi ASC,

I know this is a very old topic, but I really need HELP! lol
I saw your explanation to Josve's question.
My question is....
Does that math work for any scale?
See I build in mostly 2 scales.
Star trek ships 1/2500
Cars Bikes and Trucks 1/32

For the Star Trek ships do I divide 2500 with the scale the model is? Say 2500 divided by 700 = 3.571428571428571. Would that be 358% ?

And for cars.... 32 divided by 25 = 1.28. Would that be 128% ?

Thanks in advance for the help.

Hi Vahmp,

if you have a template which is in 1/2500 scale and would like to enlarge it to 1/700 scale then you are correct, the template must be printed at 358%.

The same goes for the car in 1/32. If you want to resize it to 1/25 then you have to print it at 128%.

In both cases the model gets bigger.

If you want to resize a 1/700 ship to 1/2500 scale then you have to divide the source value by the target value: 700 / 2500 = 0.28. This means the 1/700 scale template has to be printed at 28% to be in 1/2500 scale.

The same for a car in 1/25 scale: 25 / 32 = 0.78125, so the template has to be printed a 78.125 % to be in 1/32 scale.

Hi Revell-Fan,

That's exactly what I needed to know. I build in 1-2500 and 1-32.
AND.....
I'm lousy at math. LOL Thank you so much, you've been a GREAT HELP!
