house bricks too small?

[ColJack]

I need 4 bricks to patch a hole in an internal wall.
I got some that were left over from a wall at nans about 15 years ago ( cleaned out form nan's garage.. ) but they are too small for some reason..

the bricks are 215 x 65 ( face size.. didn't measure the depth.. ) with lots of 12mm ish holes in them..
the old ones are 220 x 70... and seem to be solid ( can't see any "frog" in the bits I took out.. ).. they are also kind of black inside if that makes any difference?

I'm guessing that it's something to do with pre / post metrication..?

is it worth trawling round the builders merchants and sheds with a tape measure, or would skip diving / freecycle be my best bet?

The small ones are metric, but for an internal wall to be plastered just make the joints a bit bigger.

Yep, metric bricks are quite a bit smaller (215x102x65mm). I think it should be quite easy to find imperial ones, they will just cost more. I have got loads in my garden as I have just removed a wall. If you really need them I shall be visiting the Midlands next weekend.

Sounds like your nan's got the old imperial bricks Col. Commonly, bricks traditionally come in two sizes, 2⅝" and 2⅞", which today in metric translates to 65mm and 73mm. Most bricks are still manufactured in both sizes.

so it's a trip round the sheds with a tape measure then?

or look out inthe local area for skips with some bricks in..
