Wire mesh sheets

Estimate full mesh sheets needed to cover a rectangular area, including the overlap required by your project.

Enter your measurements

Example values are prefilled. Replace them with your measurements before using the estimate. JavaScript is required to calculate.

Use your project’s overlap requirement. It must be at least 0 and less than the sheet length.

Use your project’s overlap requirement. It must be at least 0 and less than the sheet width.

How it is calculated

Sheets along length = 1 + ceil(max(area length − sheet length, 0) / (sheet length − length overlap)). Use the same calculation across the width. Total sheets = rows × columns.

Keep the full result when using it in another calculation. Results show up to three decimal places; very small positive results use scientific notation (for example, 1e-6). Whole sheets round upward to complete units. No extra material for waste is added.

Set the sheet direction and overlap first

Enter the area length and width, then enter each sheet dimension along the direction it will be placed. The calculator keeps that orientation for the full grid. Enter the overlap (also called a lap) specified for the project in each direction; it must be smaller than that sheet dimension.

After the first sheet, each additional sheet adds its dimension minus the overlap to the covered length. The calculation counts full sheets and does not plan cuts, reuse offcuts, or rotate sheets to reduce the total.

Why area alone can undercount sheets

For a 20 ft by 10 ft area with 12 ft by 6 ft sheets and a 1 ft lap in each direction, two sheets are needed along the length and two across the width. The fixed grid therefore uses four full sheets.

A simple area division would not show whether those sheets can cover each edge with the required laps. This result follows the entered grid dimensions; it does not determine the project’s reinforcement, required lap, or an optimized cutting layout.

Before you use the result

  • Sheets stay in the orientation entered and are not cut. The count allows sheets to extend beyond the covered area and includes at least one sheet in each direction.
  • Use the overlap required for your project. This calculator does not determine reinforcement or overlap requirements.
  • The count does not account for cutting, reusing offcuts, or rotating sheets to reduce waste.
Slab & rectangular volume

Estimate the concrete for a rectangular slab, wall, footing, or column using its length, width, and thickness.
