How to Calculate Wiremesh Requirements for Concrete Floors

Wire mesh is a popular material in construction projects, especially for concrete floors. Its function is clear: it makes the concrete stronger, more even, and less prone to cracking. However, builders or project owners often ask the question: "How much wire mesh is needed for a concrete floor?"

1. Measure the Floor Area to Be Cast
The first step is to measure the length and width of the floor area. For example, if the floor measures 6 m x 12 m, the total area is:
6 m x 12 m = 72 m²

2. Know the Wire Mesh Size
Typically, standard wire mesh has a sheet size of 2.1 m x 5.4 m, or approximately 11.34 m² per sheet.

3. Calculate the Number of Sheets
Now, simply divide the floor area by the area of ​​one sheet of wire mesh.
72 m² ÷ 11.34 m² ≈ 6.3 sheets

Since you can't buy half a sheet, round it up to 7 sheets.

4. Add a Spare Part
To account for cuts and joints, usually add 5–10% to the required amount. So, it's safer to buy 8 sheets of wire mesh for a 6 m x 12 m concrete floor project.

Conclusion
Calculating wire mesh requirements is very easy: just know the floor area, the wire mesh size, and then do a simple division calculation. With this calculation, you can save money and get the right amount for your project.
