The 4x8s for Concrete Wall Forms calculator computes the surface area and number of 4x8 sheets for concrete forms based on the wall's dimensions (length, height and width)./attachments/9e14ec60-c073-11e5-9770-bc764e2038f2/Forms.png                              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
  • (UP) Unit Price of one 4x8 (Note: Default is for 3/4" OSB from price survey below)

4x8s for Concrete Wall Form (nS):  The surface area (sA) is computed in square feet and the number of 4x8s needed to cover that area are provided.  The square feet can be automatically converted into other area units (e.g. square meters) via the pull-down menu.

Plywood and OSB Price Survey Information

The following is web survey of 4x8 sheets of plywood and OSB.  It provides the date of the web survey, the store and several price points on items that were advertised on the store's website.  This is for convenience only.  Local pricing should ALWAYS be used!

NOTE 2: Some stores carry plywood and OSB with thicknesses 1/32nd smaller than others.  Therefore, 3/4" might be represented by 23/32", 5/8" by 19/32", 1/2" by 15/32", and 3/8" by 11/32".

CAUTION: The pricing information provided is for calculating convenience with NO implied guarantees to the accuracy of the values listed. Authoritative sources should be sought to confirm any value before risking health or wealth on the veracity of the data. Furthermore, Calc gives no guarantee that you will be able to buy products at listed prices or even if they will be available.  The data provided is purely a convenience for making estimates, so we strongly recommend that one ALWAYS use local pricing and authoritative specifications.
