Metal Sheet Weight Calculator
Estimate the weight of solid or perforated metal sheet from material density, length, width, thickness, quantity and optional open-area percentage.
Quick definition: sheet weight equals volume multiplied by density. For perforated sheet, this tool applies a theoretical reduction based on open area; finished-part weight may differ because of borders, forming and tolerances.

Formula used
Weight = length × width × thickness × density × (1 − open area ÷ 100)How to use the calculator
Enter nominal dimensions
Use the overall sheet length, width and finished thickness in millimetres or inches.
Adjust perforated sheet
Enter theoretical open area when estimating perforated sheet, then verify borders and unperforated zones.
Formula, assumptions and limits
The calculator converts every dimension to metres, calculates the full rectangular volume, then multiplies it by density. Quantity changes only the total weight.
For perforated metal, theoretical mass is reduced by the entered open-area percentage. This assumes the holes are distributed across the whole measured sheet.
Actual shipping weight can differ because of density variation, rolling tolerance, coating, burrs, edge trim, blank margins, welded frames, formed flanges and attached supports.
For expanded metal, woven wire mesh, sintered mesh or complex formed parts, use a product-specific calculation or measured sample weight.

Frequently asked questions
How do I calculate metal sheet weight?
Multiply length, width and thickness to obtain volume, then multiply volume by material density. Keep all units consistent before calculating.
Can I calculate perforated metal sheet weight?
Yes, for a preliminary estimate. Enter the theoretical open-area percentage. The result assumes that open area applies across the full measured sheet.
Does the calculator include coating or plating weight?
No. Add coating mass separately when it is significant, particularly for thick galvanizing, heavy polymer coatings or precision shipping calculations.
Why does actual sheet weight differ from the result?
Nominal thickness and density are not exact measured values. Mill tolerance, alloy chemistry, borders, burrs, forming and attached components can change final weight.
Should I use 304 or 316 density for stainless steel?
Select the actual grade when known. The difference is small for rough estimates but can matter across large quantities.
Can this result be used for structural design or freight billing?
Use it for preliminary estimating only. Confirm critical loads and billed shipping weights with approved drawings, certified material data and measured finished parts.
Need a production-ready sheet specification?
Share the material, thickness, dimensions, hole pattern, margins and drawing with our engineers.
