Quick answer
Euler buckling load depends on stiffness divided by the square of effective length.
Pcr = π²EI ÷ (KL)²
How to use the Column Buckling Calculator
- 1Enter the material modulus and section I.

Frequently asked questions
Why does end condition matter so much?
Fixing both ends quarters the effective length and quadruples capacity.
Does Euler apply to short columns?
No — short columns fail by crushing, not buckling.
