Antenocite’s Workshop’s post on how big should doors be, covered the sizes for 18mm, 15mm, 10mm, and 6mm miniatures. I wanted to do the same for 25mm, 28mm & 30mm miniatures, but to include buildings, windows, and other common objects as well. Adapting Figure Scale from Wikipedia I’ve built a reference table, but as I noted in a previous post this is not exact.

[table sort="desc,asc"]
Scale, Figure Ht, mm/foot
1:61, 30 mm, 5 mm/ft
1:64, 28 mm, 4.76 mm/ft
1:73.2, 25 mm, 4.16 mm/ft
1:76, 25 mm (old), 4 mm/ft
[/table]

Now the only problem is the base the miniature is on. it’s a standard 3 mm addition to all the heights, the door article explains the why. So I’ll be adding 3 mm to all the heights , below,

Wall height

Most rooms tend to have an 8 foot (2438.4 mm), 10 foot (3048 mm), or 12 foot (3657. mm) ceiling.

[table sort="desc,asc"]
Scale, 8 ft Ceiling, 10 ft Ceiling, 12 ft Ceiling
1:61, 43 mm, 53 mm, 63 mm
1:64, 41 mm, 51 mm, 60 mm
1:73.2, 36 mm, 45 mm, 53 mm
1:76, 35 mm, 43 mm, 51 mm
[/table]

Door sizes

Looking at the standard 2040 mm high by 820 mm wide door, the numbers boil down to.

[table sort="desc,asc"]
Scale, Height, Width
1:61, 36 mm, 13 mm
1:64, 35 mm, 13 mm
1:73.2, 31 mm, 11 mm
1:76, 30 mm, 11 mm
[/table]

Windows

Windows tend to align with the top of the doors, so use the number above. The common height above ground is 3 feet (914.4 mm). The widths vary a great deal, with windows range from 19¼ in (488 mm) wide up to 69¾ in (1770 mm) wide.

[table sort="desc,asc"]
Scale, Height, Width
1:61, 18 mm, 8 mm - 29 mm
1:64, 17 mm, 8 mm - 28 mm
1:73.2, 15 mm, 7 mm - 24 mm
1:76, 15 mm, 7 mm - 23 mm
[/table]

Tables & Workbenches

[table sort="desc,asc"]
Scale, Height
1:61, 14 mm - 23 mm
1:64, 13 mm - 22 mm
1:73.2, 12 mm - 19 mm
1:76, 12 mm - 19 mm
[/table]

Chairs

[table sort="desc,asc"] Scale, Height
 1:61, 9 mm - 11 mm
 1:64, 8 mm - 11 mm
 1:73.2, 8 mm - 10 mm
 1:76, 8 mm - 10 mm

Above are common sizes for some other common wargames figures, but it’s not everything. For all of the tables of data, I’ve worked from modern Anthropometric and Ergonomic sources. Which is great of modern and near future terrain features. But when creating objects for medieval (or fantasy) you will need to consider historical references or to create the look right through educated guess work. And for Sci-fi, you will have to stick to the design principles by considering it’s function and form. (ie what it will be used for and how to make it look futuristic)

The principle is the calculate the scaled height of the object or feature and then add 3 mm for the miniature base to create the illusion of the correct scale. But do not add the 3 mm to the width of objects as it will distort the size when compared to the miniature.
