We’re often asked the question “Is it possible to scale this kit down to N gauge, or up to O scale?”, and the answer is usually yes, providing you follow certain rules…

If you’re scaling up (making something bigger)…

  • there will be a loss of quality (albeit often only slight)
  • you’ll need to use thicker card than specified… so if 0.7mm card is recommended for OO you’ll probably need 1mm or slightly thicker for O scale

If you’re scaling down (making something smaller)…

  • you’ll need to use thinner card than specified… so if so if 0.7mm card is recommended for OO you’ll probably need 0.5mm for N gauge
  • parts that are fiddly to assemble in OO scale are going to take a lot of patience to make up in N

There’s also the question of Percentages too…

“What percentage should I print out this kit to make in N gauge?”… To make things easy, we have a scale calculator on our sister website, Scale Model Scenery, which can calculate the scaling percentage for you.
