Standard sizes

[eandg]

Everything I read says design in standard size windows but I'm not exactly sure what they are? Is there a guide anywhere?

This usually refers to brick and block sizing - making sure that windows fit “courses” of bricks such as multiples of 75mm with modern bricks so lintels are in line with the head of the window. This then matches with 225mm block coursing internally (or external too if block and render)

 

Widths are pretty much any standard these days - if you have soldier detail on the heads then making them work to 75mm multiples is always useful.

As Peter says Get your brickwork sizes sorted 

All window companies will make to size No extra cost

I measured all my windows after the block work was finished and added and subtracted 7 or eight mil to window frame sizes

Thanks both - appreciated.
