OO gauge is the most popular model railway scale in the UK for modelling British railways. Here are some key facts and figures about the scale:
- Scale Ratio: 1:76
- 4mm in OO or 1:76 scale = 1ft in real life
- To convert a measurement in millimetres to OO scale, simply divide the number by 76
- The height of a OO gauge male figure would be approx 23mm based on the average height of a British male being 5ft 9in.
