Mezzanine Design Load Calculator
Beam UDL and column loads for a storage mezzanine layout.
An interior mezzanine column collects a full bay — 66 kN service for this 4×3 m at 5 kN/m². The slab UNDER each column then needs its own punching check; mezzanines have crushed many a ground slab.
Formula
Mezzanine Design Load Calculator is a free mezzanine design for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Mezzanine Design Load Calculator
Beam UDL and column loads for a storage mezzanine layout. The calculation implements w = q·bay width; P_col = q·bay area (+10% self) (IS 875; racking/mezzanine suppliers' practice). An interior mezzanine column collects a full bay — 66 kN service for this 4×3 m at 5 kN/m². The slab UNDER each column then needs its own punching check; mezzanines have crushed many a ground slab.

Frequently asked questions
What formula does the Mezzanine Design Load Calculator use?+
It computes w = q·bay width; P_col = q·bay area (+10% self), per IS 875; racking/mezzanine suppliers' practice. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
An interior mezzanine column collects a full bay — 66 kN service for this 4×3 m at 5 kN/m². The slab UNDER each column then needs its own punching check; mezzanines have crushed many a ground slab.
Can I use this for real structural design?+
It implements the exact textbook/code formula cited below the result and is ideal for sizing, checking and learning. Final designs should be verified by a qualified engineer against the full code with all load cases.
Is the Mezzanine Design Load Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
