Scale Conversions

Wanting to make your own 1:12 dollhouse scale items? First you have to consider scale and make a template. In 1:12 scale, 1 inch in the real world is equivalent to 1 foot in the dollhouse world. The best way to begin is to pull out some dollhouse miniatures you already have and measure them to replicate the dimensions. You can also measure a real object you’d like to replicate in miniature and calculate from there.

This MMM, I’m not going to walk through building any, I’ll save that for a future date, but…

However, here ere are some common household items and their miniature dimensions to get you started.

A kit I purchased from an antique store – I’ve made the books, chair and desk so far. This brand is linked above.

So what do you think? Is there some other object you’d like added to the table above? Would it be helpful if I worked these out for other scales – such as HO, 1:24, etc.? Let me know in the comments below.
