# In beamer, why do images seem to be distorted when using 16:9 ratio?

I am having a slight issue. My images in beamer seem to be distorted when using a 16:9 aspect ratio, but fine if I do standard 4:3.

Can anyone provide any assistance or help with this?

Thanks.

EDIT:

To include images, I use the following code

\includegraphics[scale=x.xx]{NAME.png}


where x.xx is changed to have the image fit on the slide properly. Usually it is set to betwee 0.60 and 0.80.

• Please show is how you include your images. The most likely explanation would be that you specify both the with and the height of your images. – user36296 Mar 11 at 10:41
• Added to original post. I don't specify widths/heights, only a scaling parameter. – eBopBob Mar 11 at 10:44
• Can you make a minimal working example (MWE) that reproduces the problem? – user36296 Mar 11 at 10:46
• Do your mean "smaller compared to the paper width" if you say distorted? – user36296 Mar 11 at 10:48

The scale option scales the image relative to the original size of the image. If you change the aspectratio of the beamer slide, the paper with changes and the image will look smaller compared to the width of the frame. If this is not the behaviour you want, you can specify the with of the image relative to the width of the frame:

\documentclass[
aspectratio=169
]{beamer}

\begin{document}

\begin{frame}
\includegraphics[scale=0.5]{example-image-duck}
\end{frame}

\begin{frame}
\includegraphics[width=.5\textwidth]{example-image-duck}
\end{frame}

\end{document}

• would keepaspectratio option, not work here? – Raaja Mar 11 at 11:45
• @Raaja I don't think the images are actually distorted, so I don't think keepaspectratio would help -- but I hope the OP will further clarify the question – user36296 Mar 11 at 11:50
• Ahhh, like that, clear! – Raaja Mar 11 at 11:53
