It is all a matter of scale...

This is a follow up to my last post about using HO scale (1/87) terrain and accessories with 15mm (1/100) miniatures. I took the time to put the following chart together (click on it to make it bigger) to show the relative differences between scales - both miniature and model railroad scales:


As you can see HO scale (1/87) is about 15% bigger than terrain and accessories scaled for 15mm (1/100) - frankly at this size though - it is not appreciably noticeable. Also look at my previous post at the measurements of items like K-Rails or Jersey Barriers - even though some are HO scale and others are 15mm - the measurements are pretty damn close.

You can download the chart above as a PDF or XLSX below:
