How many stones are used in 1m3

Bricks: this is how you can calculate the need

The meter eighth

The meter parts are a very important part of building planning. They also apply to masonry.

To be able to calculate walls more easily, divide a meter further and halve the meter parts again and again: 1 - ½ - ¼ - 1/8. 1/8 meter is exactly 12.5 cm. This dimension is the standard dimension for many works on masonry,

This is why bricks have such crooked dimensions - so that an integral number of rows of bricks can be placed on every meter, so that masonry can be planned and calculated more easily.

Common stone formats for masonry stones

With the exception of clinker bricks, which are also available in special formats, standard brick formats apply to most of the bricks.

  • NF format 24 cm x 11.5 cm x 7.1 cm
  • DF format 24 cm x 11.5 cm x 5.2 cm
  • 2DF format 24 cm x 11.5 cm x 11.3 cm
  • 3DF format 24 cm x 17.5 cm x 11.3 cm
  • 5DF format 30 cm x 24 cm x 11.3 cm
  • 6DF format 36.5 cm x 24 cm x 7.1 cm

The height of the stone is chosen so that the standard width of the mortar (€ 7.79 at Amazon *) always results in an integral multiple of 12.5 cm. (11.5 cm + 1 cm = 12.5 cm)

Stone requirement according to m²

In order to calculate how many stones you need in total, it is sufficient to know the area to be bricked in m². Then you can help yourself with the following conversion table, which indicates the stone requirement for 1 m².

When calculating the required bricks, you should always add some safety reserve and not order the exact amount required. There are also reference tables for mortar requirements - but they are more complicated.
