# Cinder Block Wall Calculator – How many Concrete Blocks per (1m2) – (1 sq ft)

Cinder Block Wall Calculator – How many Concrete Blocks per (1m2) – (1 sq ft): everything you have to take into account to know. You’ll be able to use a cinder blocks per square meter calculator.

In 1 m2 of regular block wall (citara), enter 12.6 cement blocks of 40x20cm (16”x8”’). Wall thickness can be 10, 15 or 20cm.

Before calculating blocks per m2, learn about TYPES AND CINDER BLOCK DIMENSIONS.

The number of blocks per m2 depends on the thickness of the joint (or gap size) between each block. As a rule, a joint thickness that does not exceed 15 to 18mm is recommended.

### Enter Values ​​you need, to Calculate How Many Blocks per sqm-sq ft

If you plan to build a concrete block wall, make sure to read these features before you lay the first one.

For the laying of blocks, have been considered, a 1:4:2 dosage (for 15cm and 20cm blocks) and a 1:3:1 dosage (for 10cm and 12cm blocks), in a general sense.

However, the first 3 lines, the corners, the upper 2 lines of the wall, etc., can be done with dosages of 1:3:1, richer in cement, for any wall thickness.

### How many Concrete Blocks do I need for the Project

You can use the tool to find out how many cinder blocks are needed for a wall of a particular size, estimate the required amount of mortar, and also how much materials is needed for your project.

To calculate the number of blocks that fit in a wall, you must know the following data:

• Length of the wall in meters.
• Height of the wall in meters.
• Type of block and its measurements.
• Thickness of the vertical and horizontal joints, between the blocks. It can be in the order of 15-18 mm.
• Window or door openings.
• Percentage of waste that will be considered. Normally it is considered between 3 and 5% for the blocks.

### Some Types of Cement Blocks

Cement block with 3 holes, 20cm thick

Cement block with 2 holes, 15cm thick

Cement block with 2 holes, 12cm thick

## How many Cinder Blocks do you Need per 1 square meter?

For each 1 m2 of wall, you need 12.6 units of concrete blocks (40 x 20 x 20cm) (16”x8”x8”), including 5% waste.

## 1000 Blocks for How Many sqm Does it Reach

With 1000 blocks, 400x200mm (of any thickness), you can build a wall of 80m2.

## How many 15x20x40cm Blocks per m2?

For every m2 of 15cm thick wall, 12.6 units of 40 x 20cm cement blocks are needed, including 5% waste.

## How many Blocks do I need for a 4x4m Room?

To see all the information, you can review HOW MANY BLOCKS ARE NEEDED TO BUILD A 12 BY 12 ROOM.

## How many Blocks are needed for a 20 meter Fence

For a fence 20 meters long, 3 meters high, (60m2 area), 756 units of 400x200x200mm (16”x8”x8”) cement blocks are needed.

To make the (intermediate) columns, you can place blocks (solid with mortar or concrete).

## How many Blocks are needed for a 15 meter Fence

For a fence 15 meters long, 2.7 meters high, (40.5m2 area), 510 400x200x200mm cement blocks are needed.
