1:16 is double 1:25 is it not? so if i was scaling up a kit the 1mm card would become 2mm? and what pecentage would i use for doubling the printout scale 200%?

the double of 25th scale is 12.5 scale ie 200% or did you mean to double 25th scale to get 1/50 scale?
The smaller the number after the stroke = bigger model:thumb:,
the larger the number after the stroke = smaller model
Hope this helps
1/16 scale model is not twice the size of the 1/25 model.

depending on your model I would stay with 1mm for the skins & if a boat use 2mm on the hull formers or aircraft formers.

25 / 16 x 100 = 156.25%

i didnt think 1:16 was double 1:25 its for a project i would like to start ..converting modelcard/modeliks a7v to a large scale rc tank the 1/16 is not really an issue i wanted to build the structure with 2mm perspex(which i have lots of) which would be double the 1mm used by the model at 1:25,building cardmodel style that is creating a strong frame and them skining with thin styrene cut into panels which basicly means taking the mesurements of everthing and doubling it

You might invest in a ModelCalc (brand name). It does all the conversions for you.
