Ok so how much do I reduce the print size on a 1/87 to get 1/100?

87/100ths?

Divide the (denominator of the) scale that you have (87) by the (denominator of the) scale that you want (100). 87/100 = 87%. To double check you answers, convert the same length, say 1 meter, to mm in both scales. 1 meter in 1/87 = 11.49 mm. In 1/100 scale, that would be 10 mm. With actual measurement, divide what you want by what you have: 10/11.49 = 87%. See http://www.finescale.com/~/media/imp...for_scales.pdf for more examples of resizing from one scale to another.

That's a pretty straightforward one. :-)

If you are going from a larger to a smaller plane (say from 1/48 to 1/72), know the scale factor (multiplier will be less than 1 aka 100%) take the denominator of scale you are going FROM (48) and divide it by the scale you are going TO (72) or 48 / 72 = .667

Works the other way around as well, enlarging a plane up from 1/72 to 1/48. We know the scale factor will be more than one, or one-hundred-and-something percent. Going FROM 1/72 TO 1/48 is 72 / 48 = 1.5 or 150%

Sounds easy don't it. but it's even easier if you just pay a visit to Zarkov's website ........ Scale Calculator :: ZarkovModels Card Models Store
