** **If you are thinking or planning to make a house, you need to prepare many things. This will help you buy the materials and plan for the place where it should be what. Making your own house is a dream of possibly every person, and making it secure by all means is the most critical concern one could have while building his or her own house, landscape, or fencing in cattle.

Concrete bases are a vital resource in ensuring you about fence posts’ strength and ensuring you that it will not blow away by wind flow strength or get snatched or knocked by someone/intruder. So technically, a person must know how many bags of concrete they need for the fence post.

Here is some of the little calculation margin for the fence and the concrete.

If you don’t know how much concrete will be required for your fence post to stand firmly, you can calculate the figures by measuring them. Here is the formula.

First, you need to figure out how many of the concrete bags you will have to use for a single fence to multiply further.

**How many bags of concrete per fence post?**

**You need two 50 pounds bags of concrete per fence post that is 6-foot tall and 4×4 inches wide. To calculate the concrete volume that you need to use to build a fence post you need to use the following formula: **

**Concrete volume= [height of your fence post x 0.33- 0.5 ft + width of your fence post x 3]**.

Depth of hole in inches depth 1/2 to 1/3 high | Number of concrete bags for hole w/9 inch diameter 3'' post | Number of concrete bags for hole w/12 inch diameter 4'' post | Number of concrete bags for hole w/18 inch diameter 6'' post |
---|---|---|---|

10 inches depth | 1 concrete bag | 2 concrete bags | 4 concrete bags |

12 inches depth | 1 concrete bags | 2 concrete bags | 4 concrete bags |

14 inches depth | 2 concrete bags | 2 concrete bags | 5 concrete bags |

16 inches depth | 2 concrete bags | 3 concrete bags | 5 concrete bags |

18 inches depth | 2 concrete bags | 3 concrete bags | 6 concrete bags |

20 inches depth | 2 concrete bags | 3 concrete bags | 6 concrete bags |

22 inches depth | 2 concrete bags | 3 concrete bags | 7 concrete bags |

24 inches depth | 2 concrete bags | 4 concrete bags | 7 concrete bags |

26 inches depth | 2 concrete bags | 4 concrete bags | 8 concrete bags |

28 inches depth | 3 concrete bags | 4 concrete bags | 9 concrete bags |

30 inches depth | 3 concrete bags | 4 concrete bags | 10 concrete bags |

32 inches depth | 3 concrete bags | 5 concrete bags | 10 concrete bags |

34 inches depth | 3 concrete bags | 5 concrete bags | 10 concrete bags |

36 inches depth | 3 concrete bags | 5 concrete bags | 11 concrete bags |

This is, in simple words that how you can find out the number. Some might find the above mention way a little bit difficult to comprehend. This formula below is a little easier to grab the idea and to do some calculations.

This will give you the volume of your post hole, which in turn will tell you exactly how many bags of concrete you need. Most concrete comes in bags that are anywhere from 10-80 pounds, but here you can use the same bag of 50-pounds

**Why Concrete Is a Necessary part of constructing fences?**

Mixing concrete and digging around the fences you are making may seem unnecessary, but it is quite essential to do so. On the other hand, if you have a curvy sidewalk with multiple patterns or borders, then expect to pay more than those with simple and plain, straight, grey sidewalks.

Concrete plays a role in making the surface strong, so mixing it in the material for the fence posts is the most beneficial thing since it can help you make your fences strong enough for them to bear a strong and heavy wind flow. **It remains durable and long-lasting if you add concrete to the material.** This is also a case that fences made without concrete in their bases the winds can affect those fences’ durability and easily lose them from their bases and fall off without extra effort. Furthermore, concrete used in the sidewalks has become a trend and a part of the long way.

Concrete is also an important part of the sidewalks constructions since this can make the sidewalks more stable to bear the weight plus the weather conditions. Using them in the constructive material is now referred to as the essential ingredient. It can bear the strength of the wind storm and thunder rain as well.
