Balance columns in all document

Question

In IEEE documents all the columns are balanced. Is it posible to achieve this in an article class?.

Answer 1

In addition to commented multicols or balance packages and others as vwcol (this for a single page), may be a simpler method is the package flushend

\documentclass[twocolumn]{article}
\usepackage{flushend} %balanced columns
\usepackage{lipsum} % dummy text
\begin{document}
\lipsum[1-10] 
\end{document}

Another option, that could be problematic when using floats and enunciations (theorem, lemma, etc,) is set the fontsize, baseline and lines per page in the whole document with the grid package to fill the empty space of the last page or fit the text to n-1 pages.

For example, in this MWE with a single short column in the third page can be converted to a document with two or tree pages with no empty spaces:

\documentclass[twocolumn]{article}
\usepackage{lipsum}
% for a 2 pages document uncomment this
%\usepackage[fontsize=10pt,baseline=12pt,lines=51]{grid} 
% for a 3 pages document uncomment this
% \usepackage[fontsize=11pt,baseline=14pt,lines=35]{grid}
\begin{document}
\lipsum[1-16]
\end{document}
