Ready for a math quiz?

Ok. Here's what one site says are the dimensions of a typical brick:

QUESTION: So . . . what would the actual dimensions be in mm (not inches), if they were made for, say, 20mm figures?*

Note: I am thinking of getting some small bricks from somewhere like Pegasus Hobbies bricks, and then cutting them to size with a mosaic tile cutter, but want to know how small to cut them.

Thanks.

Dan
* Though I intend to use them for 15mm, I do like the bricks to stand out a little more. Thus my question about 20mm.

Dan, I recommend you check out Precision Products plastic veneers. They make brick veneers for 15/25 mm. Gives you a templet if you insist on cutting them yourself

Conversion calculator:

For 15mm (1:100), move the decimal point two spaces to the left.

For 20mm, pick a vehicle/structure scale (1:76 or 1:87), and divide appropriately.

Most bricks would be so small they would be less than 2mm wide or deep and around 3mm at most long. Even that is probably too big.

Dan,
Why not use 1/35th scale bricks and consider them to be concrete blocks? Probably would not need as much trimming.
A standard 8' block wall should have a 2' foundation and would be about 9-10" thick.

For what it is worth the British imperial brick, used from C19, measures 9" x 4.5" x 3" deep including mortar joints (earlier bricks are shallower). The newer metric brick is 225mm x 112.5mm x 75mm, again including mortar joints.

If you are making a building rather than just making rubble, Slaters make thin plastc card with brick engraving on one side for HO/00 modellers:

Various bonds are available – your local model railway shop may well stock it.

Got to be careful trying to apply a scale reference to figures because 15mm and 20mm is actually a "size" rather than a true scale. So I just go with whatever LOOKS right to my old eyeballs and I think the H/O size bricks look good enough with either one.

Use the soldiers boot size as an approximation

You guys are amazing. Thanks!

Allen, I'm disappointed in you,

TMP link

And now, regretfully, I must shout at you- the l;ast person here I want to do so.

15MM ISN'T 1:100 20MM ISNT 1:76, UNLESS ALL YOUR TROOPS ARE UNDER 5 FOOT HIGH.

15 x 100 = 1m50cm ~ approx 4'10"

Cacique Caribe20 Nov 2009 9:01 a.m. PST

LOL.

By the way, I just noticed these:

All this scale stuff…. I use the rule of thumb: If it looks great for the scale you want, use it :)

Cacique Caribe20 Nov 2009 10:49 a.m. PST

Alfrik,

I'm starting to feel the same way too.

However, I was thinking of ordering some textured styrene sheets and wanted to find out what others where using. There's only so much you can glean from online photos, when they don't have a figure next to them for comparison purposes.

So, I think the information the guys provided has been very useful.

Even so, I ordered a couple of different sizes, just in case.

Thanks.

As long as they look all about the same size, I don't really care- I'm painting Airfix (nominally 1/72) to go up against my 20mm- the Airfix are about 22mm, which makes them approx 1:78 (ish-ish), and will look silly nex to the modern hard plastics which also claim 1:72, but as they are reviewed at 27mm, makes them 1:65 ish. I realise people come in different sizes, but having half my blokes 4'11, and the other half 6ft may look a little odd!

Last Hussar20 Nov 2009 5:11 p.m. PST

Oh, and to answer your question- about 3mm long (inc mortar) by 1mm high (well actually 3/4 mil high, maybe 7/8 with mortar)

Cacique Caribe20 May 2010 5:23 p.m. PST

Guess what guys?

I may finally get to making appropriate Post Apocalyptic ruins. I just got my Juweela bricks:

They are absolutely awesome! All 15mm, 20mm and 1/72 gamers should consider getting some.

Here's a site that I find most useful, and easy to use to boot.

One quick idea, would be once you have them all cut to size you might want to make a mold of them, for casting them in plaster in the future. I would think it would save you time and money trying to get a hold of them again and you would have all the bricks you want.
