Colinmc1 Posted December 5, 2019 Share Posted December 5, 2019 Hi I have downloaded some OO scale card buildings but I need to print them for my T-Gauge model railway (1:450) what ratio should I reduce the print by? Link to post Share on other sites More sharing options...
Dungrange Posted December 5, 2019 Share Posted December 5, 2019 Well, 00 is 1:76.2, so if you want to reduce that to 1:450, divide 450 by 76.2, which means you want to reduce your 00 plans by a factor of 5.9055. That is, buildings in 00 should be almost six time bigger than T in all directions. Depending on what software you are using, you may have to specify the reciprocal (ie 1/5.9055 = 0.16933). That means that any size in 00 is either divided by 5.9055 or multiplied by 0.16933 to get the T scale size. 2 Link to post Share on other sites More sharing options...
RMweb Premium JimFin Posted December 5, 2019 RMweb Premium Share Posted December 5, 2019 The Scalescenes advice for T gauge is to print N gauge downloads at 33%. - https://scalescenes.com/not-modelling-in-n-or-oo/ . Using the same logic, that means that OO to T would need you to print at 16.93% as Dungrange says. You may also want to think about cutting your paper down from A4 as the standard PDF print controls will just print you a small image in the centre of the page. Depending on what your printer will support, 3" X 5" is just about right. Select the highest resolution you can to retain as much detail as practical. Good luck with the cutting out!

Campaman Posted December 6, 2019 Share Posted December 6, 2019 When scaling down, you will need to think about the card thickness used as well. 1 Link to post Share on other sites More sharing options...
