Please let me know if already asked, but How to type a bigger $\oplus$ symbol?

I've tried $\mathlarger{\oplus}$ but it returns: \mathlarger⊕

Sorry for been unclear, I am looking for an "Oplus" "bigger" than the "bigoplus".

There is the bigoplus which is probably what you are after.

\documentclass{article}
\begin{document}

\[
  \bigoplus \oplus 
\] 

\end{document}

Edit:

After adding the last line of your question. If you need something arbitrarily large, you can use some other options. Here are two options using \mathlarger and \scalebox:

\documentclass{article}
\usepackage{relsize}    % for \mathlarger to work
\usepackage{graphicx}   % for \scalebox to work
\begin{document}

 \[
    x+y=z \leftrightarrow \vcenter{\hbox{$\mathlarger{\mathlarger{\mathlarger{\mathlarger{\oplus}}}}$}}
 \]
 %
 \newcommand{\Oplus}{\ensuremath{\vcenter{\hbox{\scalebox{5}{$\oplus$}}}}}
 \[
    x+y=z \leftrightarrow \Oplus \bigoplus
 \]

\end{document}

  • Sorry, no mean to offense: I knew that $\bigoplus$ worked, but I was looking for a "bigger" oplus (upvoted anyway) – High GPA Jun 11 '17 at 17:53
  • @LowGPA -- No offense at all, the question wasn't clear before you added the last line. I updated the answer. You still didn't show us why \mathlarger didn't work for you. You didn't provide a MWE, so as one can give you a precise answer. – AboAmmar Jun 11 '17 at 18:39
