The **Surface Area of a Concrete Wall** calculator computes the surface area of concrete forms based on the wall's dimensions (length, height and width).** Concrete Forms **

**INSTRUCTIONS:** Choose units and enter the following:

- (
**L**) Length of the wall - (
**H**) Height of the wall - (
**W**) Width (thickness) of the wall - (
**s**) To help with estimating the materials for the forms, this calculator has three options:- one side - this computes the surface area of one side of the wall
- two sided - this computes the surface area of both faces of the wall
- two sides and edges (default) - the computes the surface area of both faces and the vertical edges

**Concrete Form Surface Area:** The surface area (**sA**) is computed in square feet. However, this can be automatically converted into other area units (e.g. square meters) via the pull-down menu.

Concrete forms are used to contain liquid concrete and maintain a shape until the concrete has solidified. In short, it helps the concrete maintain its "form". Forms are typically made of plywood or OSB.
