In all the time I’ve been posting about the various model-making activities I do I have blithely assumed you will understand what I mean when I spout a scale at you. I’ve realised, of course, that many of you won’t have a clue how big something might be, even with the benefit of a scale ratio.
I’ve decided to adopt the idea, quite frequently used to identify scale in photographs, of using a coin as a reference. It won’t appear in every shot I take of my models, but when I think it needs clarification I’ll pop in specially trained British penny.
It won’t hurt to explain the scales and ratios a little better anyway. I’ll begin with the largest scale I work in, 1/43rd.
These figures appeared in an earlier post. They are to 1/43rd scale, in other words 43 times smaller than the real thing. I also refer to this as 7mm scale, which means 7mm on the model equals 1ft or 305mm in the real world. In the UK, this scale is also referred to as O Gauge.
This Dennis Ace fire appliance is to a scale of 1/76th, 4mm to the foot, or OO Gauge.
This Gloster Gladiator I is 1/72nd scale, or 4.233mm to the foot, which is an international standard scale for model aircraft. The scale is slightly larger than the British model railway scale of the fire appliance above. Interestingly, a larger “standard” scale for model aircraft, 1/48th, is slightly smaller than the British 7mm scale.
Don’t ask me why these variations exist. It gets worse when you compare railway modelling scales around the world. Let’s just leave it that I work to the British scales—at the moment. It’s a funny old world when you get down to scale modelling.
