# Two pictures next to a big one, to fit in textwidth [duplicate]

I want two pictures next to another big one and every picture has a different size (like the example below).

I want that all pictures keep their aspect ratio and the pictures to the right should have the same height. Also all 3 pictures should be as wide as the \textwidth.

I've tried subfigure and \resizebox, but I could not set the right heights dependent on the height of the left picture. Manually trying to fit all the sizes is way too tedious, is there an easy way to do that?

Edit: Here are more informations for my problem. My current code looks like this. I've just adjustet the sizes of the pictures until they fit (trial end error). A very tedious process.

The pictures have individual caption with (a), (b) and (c) and the whole picture has another caption.

It would be nice to manage the size of the right pictures so that they are not bigger than the left one and that alle 3 pictures don't exceed the linewitdh.

If we denote by

• a and b the width and height of the picture on the left,
• c and d the width and height of the picture on the top right,
• e and f the width and height of the picture on the bottom right,
• v the the gap between the picture on the right,
• w the desired total width (a tad less than \textwidth),

we can denote by x, y and z the required scale factors for the three pictures (left, top right and bottom right). Then solving the linear system yields

x = (2​fw + ev)/(be + 2​af)
y = (bfw - afv)/(bde + 2​adf)
z = (bw - av)/(be + 2​af)

The obvious limitation is that the second and third scaling factors are positive.

Here's an implementation.

\documentclass{article}
\usepackage{graphicx,xfp}

\begin{document}

\begin{figure}

\sbox0{\includegraphics{example-image-a}}
\sbox2{\includegraphics{example-image-1x1}}

If you want subfigures, substitute minipage with subfigure.

\documentclass{article}
\usepackage{graphicx,xfp,subcaption}

\begin{document}

\begin{figure}

\sbox0{\includegraphics{example-image-a}}
\sbox2{\includegraphics{example-image-1x1}}
\sbox4{\includegraphics{example-image-b}}

\edef\Da{\fpeval{\wd0}}\edef\Db{\fpeval{\ht0}}
\edef\Dc{\fpeval{\wd2}}\edef\Dd{\fpeval{\ht2}}
\edef\De{\fpeval{\wd4}}\edef\Df{\fpeval{\ht4}}

\edef\Dv{\fpeval{8ex}}
\edef\Dw{\fpeval{\textwidth-3em}}

\edef\Dx{\fpeval{(2*\Df*\Dw + \De*\Dv)/(\Db*\De + 2*\Da*\Df)}}
\edef\Dy{\fpeval{(\Db*\Df*\Dw - \Da*\Df*\Dv)/(\Db*\Dd*\De + 2*\Da*\Dd*\Df)}}
\edef\Dz{\fpeval{(\Db*\Dw - \Da*\Dv)/(\Db*\De + 2*\Da*\Df)}}

\sbox{0}{%
\begin{subfigure}[b]{\fpeval{\Da*\Dx}pt}
\vspace{0pt}
\scalebox{\Dx}{\box0}
\caption{First pic}
\end{subfigure}%
}\usebox{0}\hfill
\begin{subfigure}[b][\ht0][s]{\fpeval{\Dw-\Da*\Dx}pt}
\centering
\vspace{0pt}
\scalebox{\Dy}{\box2}
\caption{Second pic}

\vfill

\scalebox{\Dz}{\box4}
\caption{Third pic}

• Wow, very impressive solution. It works very well thanks. I've got just one question. Is it possible to treat the pictures as subpictures so that they get the same caption number followed by the according letter (a), (b) and (c)? Dec 30, 2019 at 8:20

an @egreg solution--https://tex.stackexchange.com/a/87976/197451

You can use some minipage environment and \sbox to measure the height of the biggest box.

Notice that I've used subfig and not the obsolete subfigure. Also subcaption can be a choice and should if you use hyperref.

The demo option to graphicx is just to produce some mock pictures; I gave them a height to show the example.

\documentclass{article}
\usepackage{subfig}
\documentclass{article}
\usepackage{subfig}
\usepackage[demo]{graphicx}

\newsavebox{\measurebox}

\begin{document}

\begin{figure}
\centering
\sbox{\measurebox}{%
\begin{minipage}[b]{.33\textwidth}
\subfloat
[]
{\label{fig:figA}\includegraphics[width=\textwidth,height=5cm]{figA}}
\end{minipage}}
\begin{minipage}[b][\ht\measurebox][s]{.33\textwidth}
\centering
\subfloat
[]
{\label{fig:figB}\includegraphics[width=\textwidth,height=2cm]{figB}}

\vfill

\subfloat
[]
{\label{fig:figC}\includegraphics[width=\textwidth,height=2cm]{figC}}
\end{minipage}
\caption{my caption. (a) is .... (b) is .... (c) is ....}
\label{fig:Test}
\end{figure}
\end{document}
