# Block wise author and affiliation

I am using IEEEtran class and I am quite new to LaTeX how can I achieve this output in proper format using IEEEtran class.

The total width of the author blocks is too wide to fit within the text block margins, so it rolls over to the next line. If you wish to keep this format, you need to reduce the size of some of some of the content, abbreviate them, or combine them. For example, I tried with \small Vellore Institute of Technology which seems to work:

\documentclass[conference]{IEEEtran}

\title{Sample paper}

\author{\IEEEauthorblockN{Taher Ali Rangwala}%
\IEEEauthorblockA{\small Vellore Institute of Technology \\
taheralirangwala@gmail.com} \and
\IEEEauthorblockN{Manish Dipankar}
\IEEEauthorblockA{\small Vellore Institute of Technology \\
manishdipankar@gmail.com} \and
\IEEEauthorblockN{Saikiran Chanda}
\IEEEauthorblockA{\small Vellore Institute of Technology \\
saikiran@gmail.com} \and
\IEEEauthorblockN{Shanu Kumar}
\IEEEauthorblockA{\small Vellore Institute of Technology \\
shanukumar@gmail.com}
}

However, the IEEEtran class documentation mentions something in this regard:

If there are more than three authors and/or the text is too wide to fit across the page, use an alternate long format [...] The \IEEEauthorrefmark{} command will generate a footnote symbol corresponding to the number in its argument. Use this to link the author names to their respective affiliations. It is not necessary prevent spaces from being between the \IEEEauthorblock's because each block starts a new group of lines and LaTeX will ignore spaces at the very end and beginning of lines.

Here is an example of this, directly from the documentation:

\documentclass[conference]{IEEEtran}
