Calculate the open area of your perforated sheet
Quickly determine the theoretical open area of a perforated sheet from its geometry: hole shape, dimensions and pitch.
A technical tool designed for design offices, designers, engineers, architects and production engineering departments.
This preliminary sizing tool also estimates the theoretical number of perforations and the weight per unit area of the sheet, based on the material and thickness.
Open area
The open area is a key parameter when choosing a perforated sheet. In particular, it affects:
However, the choice of perforation must take into account the material, thickness, geometry, pitch, perforation direction and dimensions of the part all at once.
Open area calculator
Calculate the open area of a perforated sheet in seconds and compare different perforation configurations before settling on your solution.
Quickly calculate the open area of a perforated sheet relative to its unperforated surface.

Reading the result
The ratio between the open area and the total area. It determines airflow, transparency and weight saving.
It gives an idea of the perforation cost: the more holes, the more press strokes.
It is calculated from the remaining solid area. It does not take solid margins or rolling tolerances into account.
Limits
The results provided by this calculator are theoretical. They allow you to compare perforation geometries and guide preliminary sizing, but they do not constitute manufacturing validation.
Feasibility depends in particular on the material, thickness, perforation/thickness ratio, pitch, size, perforation direction, margins and manufacturing constraints.
Every configuration is validated by our technical team before quotation.
