# 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.
