Brick Sizes

[Carlo]

Hello, all -
     I am looking for an average 'consensus' size for bricks. I know they varied all over the place, depending on the source, location, era, time-of-day, etc. I don't want to get that specific. I just want to depict a good average size brick wall. If it helps any, my era is 1900 to 1930, and the location is 'somewhere in Italy or southern France'. Prototype dimensions, or at least ranges, will be most helpful. I have been looking, but all I find is very specific examples, not averages.

     I am working on a diorama in 7/8" scale, possibly WWI military railways, or later industrial/agricultural railways.

Thanks for the help,
Carlo

Caro .. there was a discussion on 'Italian Brick' - WWII era on Armorama - http://www.armorama.com/modules.php?op=modload&name=SquawkBox&file=index&req=viewtopic&topic_id=175705

Carlo, I spent hours trying to get some average brick sizes - this was the best I could track down.

Face brick ("house brick") sizes Imperial / Metric

 Australia 9 × 4⅓ × 3 in , 230 × 110 × 76 mm
 Germany 9 × 4¼ × 2¾ in,  240 × 115 × 71 mm
 India 9 × 4¼ × 2¾ in,  228 × 107 × 69 mm
 Russia 10 × 4¾ × 2½ in,  250 × 120 × 65 mm
 South Africa 8¾ × 4 × 3 in,  222 × 106 × 73 mm
 Sweden 10 × 4¾ × 2½ in 250,  × 120 × 62 mm
 United Kingdom 8½ × 4 × 2½ in,  215 × 102.5 × 65 mm
 United States 8 × 4 × 2¼ in,  203 × 102 × 57 mm

 
Have to say that even in 7/8ths I would not spend too much time worrying about although they are variations the differences are not that great and scaled down get even less.

Nick should be able to provide a couple of foolscap pages on this subject which will be far better than anything I can add - think the most important point to remember and I have got this wrong more than once is to get the ratios right between the face and the end of the brick. Sorry non technical description but you should be able to fit 2 "ends" plus the mortar course  into the length of the brick.

I am working in 1:24-ish and I made my bricks a compromise size of 8.5mm long x 3mm high x 4mm deep so that end-on you can see the thickness and depth which measures up accurately when doing corners. I fudged on the mortar courses by making them 1mm instead of scale so that I could work the mortar material into the gaps with all of my 10 x 1:1 thumbs. I am using homemade moulds of silicone rubber and mixing casting plaster with cement oxides to get the colours. I deliberately vary the colour as I make batches so that the finished wall has more visual interest. Air bubbles are a complete pain but 90% of them can be hidden along the back face as you build. Slow but satisfying. So far I have cast 19,320 bricks and I am less than half way. Mad or what? (And yes, I keep a brick production list so that I know I have enough on hand for the building in my hand - if you get the picture.)

In the US, the most commonly used face brick is referred to as Modular brick.  A Modular brick typically measures 7 5/8 by 3 5/8 by 2 1/4 inches.  But, as Gordon said, I wouldn't worry too much about trying to make bricks to those exact dimensions.  Anywhere close to this size will look right.

I was sidelined by the gothic dungeon for a while but I have now reached 24,000 bricks. Still a way to go then.

My father was a master brick layer. I take it to mean that he could actually build all that stuff!

Excellent stuff Marc.   I thought I had a lot of brick references but now this.....I've added it to my repertoire.

Architectural Graphics Standards is a great reference book for those of us trying to build accurate models.  (The pages Marc posted are from this I believe.)
It's the architect's "Bible" for all sorts of things.

Another great source for info on individual components is "Sweet's Indexed Catalog of Building Construction".  There are several versions available on Google Books.  Here's the link to the 1906 edition:
