Model Train Layouts & Track Plans
Home What "Size" means
The "size" of a given layout is absolute value and is based on the real area that the track plan takes. The table below shows the minimum and maximum area values for each size in this site.
|Micro||0,75m2 / 0,82yd2|
|Very small||0,75m2 / 0,82yd2||1,5m2 / 1,64yd2|
|Small||1,5m2 / 1,64yd2||3m2 / 3,28yd2|
|Medium||3m2 / 3,28yd2||6m2 / 6,56yd2|
|Large||6m2 / 6,56yd2||12m2 / 13,12yd2|
|Extra Large||12m2 / 13,12yd2||24m2 / 26,24yd2|
|Huge||24m2 / 26,24yd2||48m2 / 52,5yd2|
|Vast||48m2 / 52,5yd2|
As stated above, the size is absolute value and is not related to the scale. This means that a layout with track plan in HO scale will be about 4 times smaller in area than the same track plan in O scale, while the relative size of the layouts will be equal. So, when you filter the layouts and search for track plans by "size", always observe the result's scales and scale ratios.
